MIDI’s development has changed how we listen to electronic music today.

Earlier, a musician could not plug two instruments of different brands to make music.

But with MIDI, you can connect several of them to create music.

From notes to vibrato, the cables can carry all kinds of messages.

So, how can we use MIDI cables to their full potential?

Why do we need a MIDI interface? What are the benefits of MIDI? Where to custom MIDI Cable for your project?

We will learn everything about MIDI in the following article.

Chapter 1: About MIDI Cable

MIDI is a simple technique that helps you achieve many things in the music industry.

A MIDI cable connects two different musical components of different brands.

The MIDI cable can carry event messages, music data, vibrato, panning, and more. MIDI almost acts as a remote control for the music gear.

You can play a keyboard and change the sound module’s volume, pitch, and tempo. 

A MIDI cable transfers the messages as data and not an audio signal.

Therefore, it offers more control over the other equipment.

A MIDI interface and MIDI controller are the end connectors of a MIDI cable.

The cables connect the device to the MIDI interface through a 5-pin connector type.

You need two of these cables per instrument to transmit and receive data.

A MIDI cable makes a musician’s job much more manageable.

MIDI is a technical standard that connects electronic musical instruments and computers.

It can be a communication protocol, a digital interface, or an electrical connector.

MIDI can connect various devices for playing, editing, and recording music.

Also, a single MIDI link can connect with sixteen channels through a MIDI cable.

Each of these channels connects a different set of instruments.

Earlier, electronic musical instruments from different manufacturers couldn’t communicate with each other.

However, a MIDI-compatible connector can connect modules, synthesizers, drum machines, etc.

Chapter 2: How does a MIDI cable work?

MIDI stands for Musical Instrument Digital Interface, and the device that creates these signals is the Master.

On the other hand, the device that receives the MIDI signals and responds accordingly to create a sound is known as a Slave.

All thanks to modern software, you can now create MIDI music on the computer as well, apart from the musical instrument. 

The cable that connects the master device to the keyboard or any other instrument that reproduces sound is known as the MIDI cable.

Most devices have 1-3 MIDI port types, namely MIDI Out, MIDI In, & MIDI thru. Since MIDI is a one-way communication protocol, a single MIDI port will either transmit or receive MIDI data.

If you want to send MIDI signals from your keyboard to the computer, you must connect the MIDI Out jack of the keyboard to the MIDI In jack.

MIDI Through is named so because it allows only MIDI data to pass through it, unlike MIDI Out, which sometimes also carries other information.

Earlier, the MIDI Thru jack connected many MIDI devices to form a daisy chain, all contented to a common source.

This helped in building complex systems. To form this daisy chain, you must connect the MIDI Through of the first sound device to the MIDI In Port of the next one.

In all such examples, you will need a secondary cable that can transmit signals back and forth and not just in a single direction.

Chapter 3:  Types of MIDI Cable

A MIDI cable can carry messages in various ways, i.e., through a 5-pin cable, USB, and more.

The transport speed determines the data a MIDI cable can carry and receive.

The types of MIDI cables are as follows:

USB cables connect the computer to other devices, including digital cameras and cell phones.  

HD 15 Monitor Cable – It is the most common cable. It’s blue. It communicates the image data to the monitor processor.

USB and FireWire – The music industry requires computers a lot.

So, they need to be able to get the signals from an instrument as soon as possible.

Thus, a MIDI USB cable helps connects musical instruments to computers. It directly connects the host to the drivers, so you don’t need to configure it.

The MIDI cable usually has a USB port on one end and a 5-pin one on the other.

Bluetooth – Everything works through Bluetooth today.

Many software allows the use of Bluetooth. So the next time you use sound recording software, don’t forget to check it out.

Chapter 4: MIDI Cable – Which Connectors do You Use?

A MIDI connector is at the end of every cable that can send or receive a signal.

You can connect it to an audio device or a computer. It can be of the following types:

5-Pin MIDI DIN:

The 5-pin connector is one of the earliest MIDI connectors and the most common.

It’s slower than the other high-speed digital transports like USB and ethernet.

But it can manage communication speed effectively between two devices.

Thus, a 5-pin cable connects two MIDI devices without a computer. 

USB and FireWire:

Computers have USB and FireWire ports that do not need any configuration.

It is, therefore, easier to connect a MIDI cable with a USB end between an instrument and a computer.

One end of this cable has a USB connector, while the other has the 5-pin one.

The best part about these connectors is that you must plug them in and play your instrument.

But you must install a driver on your PC to understand the information the MIDI cable sends.

TRS MIDI: 

MIDI over TRA is a connection format that uses Tip, Ring and Sleeve as connectors. In form and functioning, it lies between the 5-pin Din and USB connectors.

Earlier, MIDI In/Out used traditional 5-Pin DIN connections, but as the hardware is becoming smaller daily, using DIN connections has become challenging.

Also, MIDI uses only three out of 5 pins of DIN, so adopting the Tip, ring and Sleeve format is not a problem.

You can usually witness this Tip, Ring and Sleeve pattern in 3.5mm phone jacks, but it is also used on pedals of electronic audio processors by some renowned manufacturers.

There are two types of TRS MIDI: Type A and Type B. The basic difference between these two is that Tip and Ring sleeves have been swapped.

So, if you connect a TRS cable between two MIDI devices having different types, it won’t work.

Both the MIDI types were popular before the MIDI Manufacturer’s Association or MMA officially standardized this format and released specifications for its use.

After publishing the MIDI 2.0 specification, Type A was put on priority. However, you will find both types in all the devices available in the market.

Some products, like Teenage Engineering Oplab Akai Force, use Type A, while the Novation Circuit, 1010 Black Box and others use Type B. Some devices use both, like ALm PEXP-2 and others.

When the two types are different, it seems difficult to make connections. However, most MIDI products come with a 5-PIn breakout adapter so that you can connect any of the two types without any extra adapters.

Even if you need one, Make Noise offers Type A adapters and 1010 Music offers Type B adapters.

Now, brands have started adhering to a single type across all their line of products. But, still, you may need adapters to pair devices together as new products are coming up in the market every day.

Undoubtedly, MIDI 2.0 is going to make successful prospects in the future. You will surely see this format venturing in different directions, and this is evident with the fact that mioXl and iConenctivity’s mioXl offer RTP MIDI for MIDI connections over Ethernet.

Also, with the surge of smartphones and smartphones as music-making tools, audio controllers with wi-fi and Bluetooth connectivity are making their presence in the market. Just wait for the endless interconnected possibilities in the future.

Chapter 5: MIDI In, MIDI Out, and MIDI Thru

A MIDI port can send or receive electronic data from instruments. Each MIDI port type serves a different purpose, and here’s what they do.

MIDI In – MIDI In receives data from another device. A sequencer or other hardware can send instructions on your gear, and MIDI In will receive them.

MIDI Out – MIDI Out transfers data from an audio device to another source.

For example, if you send some information from your synthesizer to outboard gear, you use MIDI Out. MIDI Out sends the information to the MIDI In of another gear.

MIDI Out is usually for the use of DAW or sequencer. The other instruments use MIDI in or MIDI Thru.

MIDI Thru – Whatever data comes from the MIDI In port, MIDI Thru duplicates it.

Thus, you can connect multiple devices without several ports on your sequencer.

Most of the devices come with MIDI Thru capabilities.

But if they don’t, you can use a MIDI splitter. It gives one the option of multiple ports that send the information with MIDI Thru.

Chapter 6: Benefits of MIDI Cable

A MIDI setup can offer much more than just recording your audio tracks. MIDI allows you to edit your sound and performance continually.

You don’t need to re-perform the part as well. From changing a piano sound to the chord progression, you can change anything on it.

The simplest MIDI loops can also turn into a multi-track studio in no time. MIDI can make every performance of yours better in the low time.

All you need is a computer and a MIDI controller. You can sequence, edit, and arrange your sound directly from the PC.

You can then create hundreds of tracks with different sounds for each.

Can also add a synthesizer to the mix to get the full analog sound.

Chapter 7: Custom MIDI Cable — How Can We Help?

If you’re looking for a way to set up your musical instruments, we can help you. We will help you find the right MIDI cable as per your needs.

We also customize the cables according to your needs easily.

You can then synthesize, edit, and produce your music. You can connect up to sixteen channels with your MIDI cable and produce music.

Can contact us for any information you may need about the MIDI cables.

Length of the MIDI cable:

The MIDI cable comprises a head and the length of the insulated wire. Though available in different lengths, MIDI cable with the most effective results should be 20 feet or less.

For long-distance connections (more than 20 feet), you need high-quality MIDI cables because low-quality cables do not guarantee the integrity of signals.

Types of MIDI cables:

There are different types of instruments and devices, and for them, different MIDI cables are available to make the connections possible and compatible.

As the musical instrument connects through MIDI, the cable has MIDI connectors at both its ends. However, computers do not have MIDI sound cards or MIDI in jacks.

So, if you want to connect your musical instrument to a computer or any other recording device, the cable should have at least one end with a USB or Firewire connector.

You can also use an adapter to change a MIDI connector to USB or Firewire.

MIDI couplers help you plug two MIDI cables into them, allowing extension of connection.

Alternatively, the transition from male MIDI to female one and vice versa is possible with MIDI splitters and Y-cables.

Some other types of MIDI cables include:

Colored MIDI cables

Braided MIDI cables

Bus-powered USB MIDI

Right-angled 5-pin MIDI cable and so on

Conclusion

A MIDI cable can make the life of any musician easier. It is a great way to connect different musical instruments.

You can also connect your connector to a computer and produce music anytime. The only issue with a 5-pin connector is that it sends the data slowly.

The LAN or Bluetooth connection prevents us from transmitting the right data.

What is the FCT test? This is a question that you may have if you are new to PCBs. In this comprehensive guide, we will introduce you to the FCT test and explain what you can use it. FCT test is a key component of quality control in the PCB manufacturing process.  And it is essential that your PCB manufacturer performs this test on every batch of boards they produce. We will discuss the benefits of FCT testing and explain how it can help improve the quality of your PCBs.

What is FCT in PCB?/What is the ICT electronics test?

Multimeter probes examining a computer circuit board

FCT test, or functional circuit test, is a type of testing performed on PCBs during the manufacturing process. And this test checks for shorts and open circuits in the PCB and verifies that the board is functioning correctly. In addition, FCT is an important step in quality control for PCBs, and it typically gets performed after the soldering process.

Why is FCT important?

Oscilloscope Probe on Electronic circuit

FCT is important because it helps ensure that the PCBs function correctly and there are no manufacturing defects. Besides, this test can identify problems with the PCB before shipping to the customer, which can save time and money.

What is Required For Functional Testing?

In order to perform an industrial FCT test, you’ll need the following;

Test Fixture

A test fixture helps keep the PCB in place during the test. It controls the DUT (device under test) as it allows exposure to external variables and punctually records its actions.

Key Elements of FCT Fixtures

An FCT fixture is usually custom-designed for every PCB to provide the following primary functions;

• Test point interfaces – these are interconnect mechanisms such as edge connectors, test probes, or pogo pins that are integrated to make electrical contact with standard pads or test points on a PCB. Some popular options include flying probe fixtures and a bed of nails.
• Physical board holding – fixtures incorporate plates or a frame that securely holds the PCB in a certain position and orientation. This could include fixtures such as clamps or vacuum channels to maintain consistent contact.
• Grading for safety – fixtures provide insulation or shielding around PCB to provide protection against electrical hazards while you’re testing. Covers and ground planes are commonly used.
• Durability – a test fixture is designed to withstand the rigors of repeated testing over countless test boards without failing. Often, materials such as stainless steel are used.
• Handling ease – a fixture is designed for quick unloading and loading by handling equipment (such as robots) or operators. Thus improving test throughput and efficiency.

Two Primary Categories of Fixtures

• Flying Probe Fixture

A flying probe fixture uses movable test probes on precision robots to target specific test points on a PCB. Thus providing improved versatility to reach points on a complex board geometry. Flying probes can test highly sophisticated analog and digital circuits.

Also, there are hybrid fixtures that offer both flying probes and a bed of nails. The type of fixture you choose depends on your PCB’s complexity, design, test access requirements and various other considerations.

Caption: Flying Probe Fixture

• Bed of Nails Fixture

This fixture uses an array of spring-loaded pins or nails to contact test pads on the PCB. It provides access to test points across the entire board area. Bed of nail fixtures can test simple analog and digital circuits.

Connective Interface

Usually, testers use probe cards to connect your test equipment to your PCB.

System and Sensors 

These create the necessary ideal conditions to simulate the working environment for your test target board, ensuring it functions in pre-planned states as it obtains parameters for every state.

Test Software

Often referred to as firmware, test software is an application that manages the test method and collects key information.

It enables operators to perform functional tests automatically via a computer. The software communicates with external programmable instruments like communication ports, digital multimeters, and I/O boards.

The software works with the fixture interfacing the instruments with the device under testing to make it possible to perform an FCT.

There are some benefits of the FCT test for your PCB assembly.

First and foremost, FCT can improve product quality by detecting functional defects early in the manufacturing process.

Secondly, It allows you to make changes to the design quickly and easily without incurring high costs.

Lastly, FCT can save time by identifying potential problems with the PCB before shipping it to the customer.

PCB FCT Test Classification

Control Mode

The most productive PCB FCT tests are mostly semi-automated or fully automatic. Due to the demand to improve product efficiency and the fast development of technology, most functional testing methods are now fully automated. The testing software application (firmware) enables automated functional testing.

In order to interface with your test applications normally you should employ an external programmable instrument like a digital multimeter or I/O board.

You can perform FCT tests using instruments connected to devices under test via a test application and fixture. However, semi-automated or manual FCTs are popular when looking to decrease production costs and streamline design.

Controller

Embedded CPU controllers and MCU controllers – these are easy and quick FCTs for specialized programs and circuits for output and data display. 

PC controller – this is the most popularly used FCT as a result of its accessibility. Furthermore, its low prices contribute more to its use.

In such a case, the file processing and data output of the test results could be accomplished on a workstation’s operating system.

Also, the overall functioning of the test application is rather straightforward.

PCL controller- during development mode, it is a standard FCT focusing on the need to regulate induction components. In professional industrial control, the most commonly used controllers are PCLs.

ure the voltage levels on the PCB.  Also, we use the breadboard to connect different components of the FCT test.

What is the Process of the Functional Circuit Test?

Planning the tests you plan on performing is normally the first step before you start FCT testing. 

Functional testing involves connecting your electronic device to your test system and running a series of tests in order to make sure all the components are properly working.

The proper electrical connection between various parts is verified by applying signals and power and measuring the output in load and voltage.

Depending on the complexity of your PCB design, operators need to perform various tests, including logic tests, signal integrity tests, and power-on tests.

If the tests uncover any issues, professionals isolate the problem and determine the root of the problem. Any issues have to be addressed before the product is released into the market.

If the board is clear on all tests, it is cleared for further production operations and later released to the market.

Manufacturers must make sure that all FCT tests are done in accordance with industry regulations and standards.

This entails ensuring the test system is properly calibrated and maintained, and every element is tested according to its specification.

Furthermore, manufacturers have to document every test result and keep records of any modifications or changes made during the process.

Defects and Faults Found By FCT

FCT testing for different circuit issues and defects that could occur in the PCB fabrication stage. By using test signals and measuring the output response. The following are some of the issues that could be detected.

• Short circuits – unintended conductive bridges between 2 points not meant to be connected according to the design schematics. This could be caused by unwanted soldering, drill errors (such as plating through a hole wall), or copper smearing.
• Open circuits – breaks in the conductive path between points that should be connected according to the design schematics. This could be caused by incomplete holes, fabrication flaws, thinning and gaps in copper traces.
• Leakage – unwanted current flowing through points that should be isolated, thus indicating issues with the insulation resistance. This is often a result of contaminants such as residue on the PCB surface or moisture.
• Value faults – when impedances such as resistances or capacitances are out of tolerance from their designed value as a result of flaws or variations in fabricated parts on the PCB.
• Intermittent faults – defects appearing intermittently as you conduct the tests, indicating unstable or marginal connections that will likely cause reliability problems over time.
• Impedance faults – improper characteristic impedance of transmission lines, such as microstrips, that could impair signal integrity at high frequencies.
• Crosstalk – unintended signal coupling between neighboring components, traces, or vias as a result of fabrication variations. This could cause noise and interference. 
• Circuit logic faults – circuits failing FCT testing as a result of problems with the fabricated components or connections preventing proper logic function according to the design.

Summary

Choosing the proper BNC connector to suit the cable for your project usually comes with a price. The price typically needs to be an appropriate assessment of the intended line.

A significant issue plaguing most corporate organizations and teams is choosing the suitable cable. BNC cables remain one of the most used cable types across different industries.

This article presents all you need to know about the BNC cable. You will learn about Siamese cables, connectors, benefits, and applications of other types of lines.

BNC Connectors

What is a BNC Cable?

A BNC cable is a coaxial cable that utilizes the BNC connector, a type of RF connector.

You can use a BNC (Bayonet Neill-Concelman) cable to connect various devices such as televisions, radios, and other radio frequency devices.

A notable difference between BNC cables and other regular cables is that BNC cables use a coupling nut to fit the cable into devices.

BNC cables were once very popular and extensively used as computer network cables.

Over time, they lost their touch due to the introduction of various forms of digital technology that limit all cable types to certain devices.

Caption: BNC Cables

BNC Cable Types

Like other video cables, resistance or impedance is the core feature of BNC cables. Unlike S-video, composite, or component cables, BNC cables offer an impedance of about 50 – 75 Ohms.

Luckily, BNC connectors are compatible with several coaxial cables, such as RG-6, RG-11, and RG-59.

BNC Cable Uses

BNC cables are popular among radio and video frequency applications lower than 3 GHz. 

The BNC connectors use small amounts of plastic dielectric on every connector with a slotted conductor on the outside. 

As the frequency increases, so does the signal loss. Radio frequencies that are slightly higher than 3 GHz could generate a signal. 

As the frequency increases, the signal isn’t that constant. 

So, you can use BNC cables for various signal connections, such as aerospace electronics, amateur radio antennas, serial analog and digital interface video signals, and electronic test equipment.

For commercial video devices, you can use a BNC connector for composite video signals, and you can use it instead of using an RCA connector. 

Most electronic devices that use an RCA connector can use a BNC cable with a simple adapter. 

Plus, you can find BNC cables at various recording studios. Different instruments synchronize, enabling the digital recording equipment to easily work with timing signals.

What is a BNC Connector?

A BNC connector is normally used with a coaxial cable designed to facilitate the transmission of high-frequency signals over a long distance with minimal signal loss.

Often, BNC connectors are used in networking and video applications via a rotating ring that securely connects the two cables. 

Each cable’s inner conductor connects to a pin inserted in the opposing connector. Then, to secure the connection, all you have to do is twist the rotating ring.

There are several advantages to using BNC connectors, such as

• BNC connectors are easy to use
• BNC connectors are compatible with a wide variety of devices
• BNC connectors are capable of providing a secure and low-loss connection

BNC Connector Uses

You can use BNC connectors with both digital and analog signals. However, they’re mostly used in digital video applications requiring low signal loss and high bandwidth.

As previously mentioned, BNC connectors enable easy and simple synchronization of different components. 

So, they are popular with video surveillance, especially in instances where they are analog cameras.

Furthermore, if you want to upgrade and update your system, BNC connectors make it much more feasible. 

The BNC connector connects your analog video components from the cameras to your DVR or TV monitor. It firmly snaps into place to provide a secure and quality connection.

BNC Connector Types

Below are the various types of BNC connectors.

Twist-On BNC Connector

This connector is easy to use as you don’t need any tools to attach it; all you need to do is twist the connector onto your cable, as the name suggests. 

However, you might need a few tools if your cable wasn’t already stripped. 

Some people claim that twist-on BNC connectors are unreliable because they don’t provide a secure connection as compression or crimp connectors. 

However, if you properly prep your cable, a twist-on BNC connector should provide a secure enough connection.

BNC twist-on connectors

Crimp-On BNC Connector

Crimp-on BNC connectors are available in two styles: 3-piece and 2-piece. However, people rarely use the 3 piece. 

To install cables using a 2 piece crimp-on connector, you’ll need a cable stripper and a crimping tool. 

Although the connection process takes longer than the other connectors, the result is worth it. 

You get a secure connection and a guarantee that your cables won’t get loose anytime soon.

F-Compression BNC Connector

You can install F-compression BNC connectors by attaching a compression connector to your coax cable, then screwing on the BNC connector.

Most installers prefer the method because you don’t guess the length of your coax core, which can be seen; therefore, there’s minimal room for error.

F-Crimp BNC Connector

The crimp connector is similar to the compression; the only difference is that the crimp connector uses a crimp-on connector.

Like the above method, the crimp connector is first attached to a cable, then a screw-on BNC connector.

BNC crimp-on connectors

BNC wiring

There are different types of coaxial cables with their associated BNC connectors, and it is advisable to read the manufacturer’s instructions before starting the attachment task.

Nevertheless, here are the steps you should follow for attaching BNC connectors. 

How to connect BNC Twist-on Connectors:

Use a coaxial cable stripper tool to cut the ends of the coaxial cable. In our testing, the exact length of the cut was 9/16 inches. Be careful not to cut the copper braid on the cable.

Test the length by inserting the cable into the connector. Press on the cable so that you feel the inner opening of the connector grasping the core of the cable.

Turn the connector clockwise. Turn until the connector is snug, but do not overtighten or it will bend the coax core.

Pull on the end of the BNC connector to confirm that it is securely connected to the cable.

How to connect BNC Crimp-on Connectors:

Prepare the cable and ensure the cable ends are flush.

Insert the coax cable into the cavity of the cable stripper with a notch for the cable conductor.

Align the blade 1/4 inch from the cable flush end.

Rotate the stripper around the cable in a circular motion.

The outer jacket, braid, foil shield, and dielectric insulator will come off easily after a few turns.

Now, use another cavity to peel off the outer jacket only 1/4 inch from where the conductor is exposed.

Fold the braided shield over the outer jacket.

Install the center pin or “male contact.” The center conductor must be long enough to go all the way inside the pin, but the open end of the pin must be against the white dielectric.

Use crimping pliers to tighten the pins.

Slide the sleeve over the end and down so it doesn’t get in the way of the cable.

Leave the ends of the braid slightly open and ensure there aren’t any stray wires flowing toward the tip that might come into contact with the center conductor.

Then, slide the body of the connector over the dielectric underneath the braid. Again, make sure there aren’t any stray wires underneath the knurled section.

Slide the sleeve back toward the ends and slip it over the braid.

Using a crimping tool, crimp the sleeve onto the cable and connector.

It must crimp onto the open braided part for electrical connection and the bits of the outer protector for mechanical connection.

As a final step, when there is continuity on both ends, use an ohmmeter to make sure the electrical connection is correct.

Ensure the center pin is not shorted to the case and that both ends are electrically connected.

Choosing a suitable cable is hard, and figuring out its harness design is even more challenging. It requires a lot of practice to recreate the perfect setting. For that, the cable manufactures colored wires so that it is easy to connect and maintain them.

Let’s find out the color codes for RJ45 and how to achieve it.

What are RJ 45 Connectors?

Ethernet networks use RJ45 connectors to transfer audio and video data. They are standard except for the highest-end Cat.8 networks, but it’s also used on Cat.1, Cat.6, and Cat5e networks.

Initially, they worked as a more compact and affordable replacement for traditional hardwired telephone setups. As a result of its plug-and-play nature, the setup is simplified.

RJ45 is more flexible than its predecessor, RJ11, and may be utilized in more comprehensive situations, such as Ethernet networking, telephone, and factory automation.

In most cases, people will use some combination of Ethernet connections, modems, personal computers, portable media players, and printers.

Caption: 8 pins on the RJ 45 ports

About the Ethernet Cable

There are four pairs of wires in an ethernet cable.

Category 5 or above Unshielded Twisted Pair (UTP) ethernet cable is widely available in bulk from electronics retailers and home improvement stores.

For 10/100 functioning, Cat 5 is necessary; for gigabit, Cat 5e is preferable; and for some degree of future-proofing, Cat 6 or higher is recommended.

For more protection against outside interference, you can utilize STP (Shielded Twisted Pair).

Although there is a wide variety of bulk ethernet cables, they may be broadly classified into two groups: solid and braid stranded.

Desktop patch applications benefit most from using stranded ethernet wire. It is simpler to operate, more flexible, and more durable than a solid Ethernet connection, but it is only helpful for wiring shorter distances.

And you can use the Ethernet cable with solid conductors for permanent installations over extended distances. 

When running an Ethernet connection across a plenum or other air-handling facility, you must utilize a plenum-rated cable, for instance, underneath a raised floor or above a false ceiling.

Identifying the sort of ethernet cable inside a package or from a label may be difficult or impossible. Therefore it’s best to remove one end and look inside.

RJ45 ethernet port color code

 It is common practice to utilize patch cords to connect computers and network hubs. T568A and T568B are the two different types of wiring standards.

The more prevalent T568B standard and the less common T568A differ in how their wires are colored and organized.

One key distinction is that the green and orange pairs of pins are reversed in orientation.

Color-codes for rj45: Functions of 8 Pins in RJ45 Port

Pins 1 and 2 in the RJ 45 port on your computer and router are for sending data; pins 3 and 6 are for receiving the data, and pins 4,5,7, and 8 are for the electrical supply for Point-of-ethernet devices.

However, the RJ45 ports on the hub or switch receive data from pins 1 and 2, transmit data from pins 3 and 6, and connect the power over Ethernet (PoE) devices through pins 4,5,7, and 8.

Color-codes for rj45: RJ45 Plug Termination

Uplink port transmitting and receiving pins 1 and 2 on 10BASE-T and 100BASE-T nodal devices like PCs and routers.

However, hubs and switches use pins 3 and 6 for transmission and pins 1 and 2 for reception. For 1000BASE-T and higher speeds, you need all four pairs.

Connecting the transmitter to the receiver pin allows two networking devices to exchange data. 

Because of this, when we need to link two completely different gadgets, such as PC to PC, Switch to PC, Router to Switch, etc., we employ straight-through pinout patch cable terminations (both sides need to have the same connection criteria; either EIA/TIA 568A or EIA/TIA 568B).

However, connecting two similar devices, such as PC to PC, Switch to Switch, and Router to Router, requires only a T568A termination at one end and a T568B termination at the other. Crossover cables are a common name for these kinds of patch connections.

In many cases, current gadgets can detect when you connect them and initiate crossover transmission automatically.

Color-codes for rj45: RJ45 Jack Termination

The module’s internal wiring dictates the colors assigned to the jacks. Typically, jacks use lead frames (a single metal strip) or printed circuit boards (PCBs) to transmit signals from the cable or the jack’s rear to its contacts or pins.

Connectors with a color code indicate whether they are T568A or T568B so that you know the type while terminating the jack.

Moreover, the jack color coding also varies; hence don’t forget to look over the label carefully. Different manufacturers, or even models of the same manufacturer’s connectors, may use different color codes.

Caption: the color code of the T568A standard

Caption: the color code of T-568B standard

Types of RJ45 Ethernet cable and RJ-45 wiring

There are many types of RJ45 Ethernet cables. Which type should you choose? In many cases, tradition influences the choice. Because of AT&T’s previous 258A color code, T568B is standard in America.

Although you can use either T568A or B for cabling in new construction, it is essential to be consistent so that plugs and jacks align.

Color-codes for rj45: Straight-Through Cables

Straight-through cables have identical terminations on both ends, conforming to the EIA/TIA-568-A or B standards.

Nowadays, most systems use the T568-B standard to terminate patch cables. However, you can use both standards in straight-through cables.

The standard for linking MDI and MDIX devices is a straight cable. Thus, you will connect the MDI and MDIX interfaces via a straight cable, even though they are very different devices.

Additionally, 10Base-T and 100Base-T use two pairs of wires in a four-wire (UTP) line. On the other hand, 1000Base-T uses all eight wires in a quad-pair cable.

Color-codes for rj45: Crossover Cables

Cross cables link two devices with the same type of RJ45 Port, such as a personal computer (PC) to another PC, a switch to another switch, or a router.

For this purpose, we are using an RJ45 cable to link two devices with identical pin configurations. You have to link the sender pin with the reception pin for two devices to exchange data.

So, as you make a cross-connection, you’ll need to adhere to the EIA/TIA 568A regulation on one end and the EIA/TIA 568B specification on the other.

The color of the crossover cable makes it easy to identify the appropriate connectors.

Following this logic, you will connect Pins 1 and 2 to Pins 3 and 6. On both ends of the cable, you’ll use the identical formula.

Color-codes for rj45: Rollover Cable

Using this cable, you can access the router or switch console on a Cisco device. A computer or laptop on one end, a network hub or switch on the other. The RJ45 connector on one end of this cable pairs up with a DB9 serial port on the other. 

Moreover, Pin1 on one end connects to Pin 8 on the other, making this type of cable known as a “rollover.” Following that, pin2 on one side links to pin 7 on the other, and so on.

The EIA/TIA 568A and 568B standards can be used to set up a rollover cable. Remember that the other side requires a full reversal of the color scheme, regardless of the criteria you choose. 

Moreover, the cable is not for sending or receiving data. It is only for configuring the router.

Color-codes for rj45: Loopback Cable

RJ45 loopback cables have a jack with four contacts and are best for loopback connections in Ethernet networks. In such cables, all eight contacts are used in a redirected or looped transmission in Gigabit Ethernet.

How to Build an Ethernet Cable?

Building an Ethernet cable is simple. Even while patch cords with factory-terminated plugs are widely available, it is not unusual for users to create patch cables in the field. Here we go.

• Get the required length by pulling the cable off the reel and cutting it with wire scissors or cutters. You can connect RJ-45 connectors once the cable draws through the opening.
• Remove the cable’s outer jacket, starting at one end, using a wire stripper or a knife. Make sure you don’t nick the wires, or you’ll have to start over.
• Flatten the cable, separate the pairs, and rewire it so the ends match up. Cut the wires so their ends are parallel, and no more than 1/2 inch of wire remains. Create a flat surface between your forefinger and thumb and flatten the end.
• Ensure the clip is facing down or away from you when holding the RJ-45 plug. Now, push the wires firmly into the connector. Also, be sure to connect the wires in the correct order. Hold the cable securely while you crimp the RJ-45 connector.
• Verify that you have aligned the wires with the correct polarity and that the crimped link is not ready to unravel. You need to check the Ethernet cable to see if any of these are wrong.

FAQ About RJ45 B Color Code

Does It Matter If I Use The RJ45 A or The RJ45 B Color Code?

There’s no electrical difference between T568B and T568A wire sequences. Therefore, none of the wire sequences is superior to the other. 

The only difference between the two is in regard to how frequently they’re used in a certain type of organization or region.

In the United States, the majority of ethernet installations adhere to the T568B wire sequence for the RJ45 color code.

Also, it’s the most commonly used standard when cabling for businesses, while the T568A is used in all US government installations.

However, in Pacific and European countries, the most commonly used standard is the T568A.

Can You Mix The RJ45 A Color Code With The RJ45 B Color Code?

Mixing T568B and T568A will result in connectivity issues. 

Keep in mind a network jack has 8 pins. When a cable connects two different devices, each pin has to match each jack in order to establish a proper connection.

Mismatched wiring does not allow all eight pins to connect properly; therefore, the devices will not be able to communicate. 

However, if you mix T568B and T568A in a single cable run, it will result in crossed pairs.

Why is RJ45 B Color Code Much Better?

In a modern data network, both the T568B and T568A function and perform the same from a practical standpoint.

Just make sure to use the same color code at both ends of the cable, and you shouldn’t encounter any problems.

T568B and T568A are the termination standards used by internet backbone infrastructure and internet providers, all the way down to businesses and homeowners.

The only actual difference between them is the orange and green pairs. In every cable, these two sets are switched.

Despite being switched, both are still effectively straightforward or direct connections.

Although there’s a lot of misinformation regarding the two, fortunately, most of it is benign.

None of the misinformation is malicious, but sometimes, when people get used to doing something a certain way, it becomes popular.

Often, the cause of misinformation is outdated information.

There are some rare instances (for example, United States government contractual requirements) that the T568A may be required for use.

Therefore, unless your client prefers a certain standard, the choice comes down to your personal preference.

If you don’t have specific requirements regarding the standard to use, just choose one and stick to it.

How To Crimp RJ45 to T568B Standard?

1. First, gather the necessary tools; these include cable caps, RJ45 plugs, one pass-through RJ45 crimping tool, and an ethernet cable.
2. Insert your cable cap into a wire for later use.
3. Unlock your RJ45 pass-through crimping tool, then press down on the handle to push out the lock button.
4. Use a ruler to measure 3 cm for the terminal and mark it.
5. Place your ethernet into the strip port of the crimper and rotate it in a circular motion to easily strip off 3 cm of insulation using a sharp blade.
6. After, you should be able to see the exposed twisted four-pair wires in all colors.
7. Separate the wires, then cut off the film inside or aluminum foil. Ensure to keep the wires in the correct order as illustrated by the table below.

8. Cut the wires from the brown to the white-orange at an oblique angle. Ensure the oblique angle isn’t too steep.
9. Reserve about 2.5 cm of the orange-white wire, followed by cutting the wire horizontally.
10. Attach your core wire to your RJ45 plug.
11. Extra wires are normally longer than the plug. Ensure all the colors are in their correct positions.
12.   Insert the cable cable left before you plug upwardly.
13. Place the plug into your crimping tool.
14. Push the handle to your bottom crimp. Ensure you push the wire into the end of the plug’s hole.
15. Ensure it’s functioning, then insert your cable tester.

Conclusion

After knowing the color codes for RJ45, you must have a clear picture of Ethernet Cable Types.

Further, ethernet cable can be made in many configurations, be it straight or crossover, Cat 5e or Cat 5, plenum-rated or riser-rated, and so on.

Each configuration contributes to different functionality and usage. Here at Cloom, we offer wiring harness solutions so that you don’t have to worry about perfection.

Wire harness assemblies are an integral part of all-electric systems, and all-electric systems come with factory-made harnesses. However, sometimes, you need to build your harness to improve its appearance or make it fit for an application. If you know the basics of wire harness making, it becomes easier and less time-consuming. This blog post will teach us how to construct a DIY wire harness assembly.

What Do I Need To Know Before Making a Wiring Harness?

In order for an application to work as intended, you should consider every component and cable assembly that you plan on using on the wiring harness. Therefore, it’s not a bad thing to remind yourself about the basics when designing a cable harness.

Purpose

Ask yourself what else your wiring harness needs to do besides transmitting power and electrical signals between components.

Think about the specific needs of your application. For instance, does it need to fight vibration?

Also, does it need protection against electromagnetic interference or whether it can withstand pressure, heat, and other conditions? 

Wire Selection

Below are the main factors to consider when choosing a wire for your design.

Wire Specifications

Consider the electrical requirements determined by the wire’s thickness or gauge, especially the amount of current your wire needs to convey and its carrying capacity, all measured in amps.

Keep in mind that length is also an important factor, as a longer wire means you’ll lose more voltage through heat and resistance.

You can solve such a problem by increasing the gauge, which in turn increases the amp capacity.

Environmental Conditions

Ensure the wire you choose can withstand the environmental conditions of your application’s environment.

For instance, if you plan on exposing your harness to high temperatures, you should choose a wire with a high-temperature rating.

If you plan on exposing the harness to moisture, then select a wire with a moisture-resistant coating.

Mechanical Properties

A wire’s ability to withstand mechanical stress determines the wire’s correct and efficient output, which includes twisting or bending without losing electrical properties or breaking.

Also, if you plan on exposing the wire to scraping or rubbing, choose one with efficient abrasion resistance. 

Wire Connection

Connectors create electrical circuits while protecting the wires from environmental conditions like EMI and abrasion.

The connectors you choose should be in regard to their mechanical and electrical properties. The wires will influence the connectors; therefore, you should know the wire’s length, material, and gauge.

You should consider circuit density and size as well as space limitations. Also, if necessary, it’s important to consider the ease of disconnecting and connecting wires. 

The Termination End Matters, Too

You’ll need specific connectors for board-to-wire, board-to-board, or wire-to-wire. A clamping device and other hardware are used to install and support your connector; therefore, it’s important to prioritize quality.

The Importance of Standardization

Using standard connectors and other components will make it easier to source what you need. Although the search could still be time-consuming, it’s best to go further with the Arcadia Component Database.

There you can quickly search for parts and find necessary documentation for parts. Also, it helps avoid duplication in inventory and enables you to quickly review your price details.

Routing:

Ensure to route the wires in a way that makes accessibility easy. Optimum positioning is important as you want a harness that’s easy to install and maintain. Also, any wires that might need repairing or replacing should be easy to access.

Furthermore, it’s important to consider any potential sources of electromagnetic interference that could affect your wiring harnesses’ performance. The routing in a wire and cable harness should reduce the risk of interference and prevent signal degradation.

Segregate your Wires.

Do this according to their signal type, function, and voltage to help prevent interference and ensure your wires are correctly connected to their respective devices. It’s important to ensure all your wires are routed to the correct system points.

Strain Relief

Designing a wire harness assembly for strain relief will help avoid future problems. If you don’t do this, your wires might break or loosen as a result of pulling, vibration, or other forces, especially in applications that expose the harness to extreme mechanical stress. 

Add Strain Relief Components If Necessary

The first step is identifying potential sources of stress. You should consider cable management to assist with strain relief.

Components like cable clamps, cable ties, or grommets could help protect the wire harness assembly. Your choice is dependent on your application, environment, and design of the harness.

Grommets

Also, determine the ideal spots in your harness for strain relief components. Normally, you should place them in positions where the wire is exiting the harness, as these are more vulnerable.

Furthermore, ensure your harness is flexible enough to facilitate bending and movement while maintaining its structural integrity.

Material Matters

Don’t forget to consider the material for the strain relief. The material should withstand environmental conditions while providing the properties you need, like chemical resistance and strength. 

Wire Harness Diagram

It’s advisable not to try and come up with the diagram by hand. You can use a wire harness design tool like ECAD or computer-aided design to create a good wire harness diagram.

Plus, you can check your design to observe its behavior and voltage drop in real-time to make necessary adjustments using a browser.

Also, you can check to determine if your design meets safety standards. 

Ensure Flexibility:

Ensure your harness is flexible enough to facilitate bending and movement if necessary, while maintaining its structural integrity.

This will help you save costs, thus optimizing the design phase. Manual harness diagrams are an efficient way to work.  

Protective Covering:

Cover your wire harness with a protective sleeve or sheath to protect it from damage. Also, providing an additional layer of insulation will protect the cables and wires.

To do this, you need to understand the environmental conditions you plan on exposing your wiring harness and the material of the protective covering.

Pay Attention To Material Properties

For instance, if you are designing an engine wire harness, chemicals, fluids, rattles, and vibration are a concern.

Your protective material should be able to handle all these threats. Protective coverings are different according to type, such as heat shrink sleeves, tape, pulled-on braided tubing, and spiral wrap.

Also, the protective covering helps keep your wires in a neat bundle.

Caption: Heat Shrink Sleeves

Testing

Testing should always be on your mind, even during the early stages. Do not overlook anything when testing the prototype, or you’ll be risking downtime during the quality control stage, bringing you back to the design process.

Ensure you have all the necessary equipment for testing electrical integrity. It should be able to find problems across all conductors of the UUT (Unit Under Test) without human intervention. 

Since you’re testing the quality of the connection, you should include electrical load and embedded resistors. The test should:

• Check for intermittent connections
• Allow you to set up dual thresholds or limits
• Measure resistance

Documentation

Documentation is vital for service and after-sale consultants. This includes an intelligent, technical publications export, including the schematic design and connector information, plus locations embedded into an offline/online viewer. This makes it easier for your engineers to understand and the technical publications to generate.

Compliance:

The design and manufacturing process of a wire harness is subject to standards and regulations.

Regulatory and Safety Standard Agencies

Every region enforces the testing of electrical devices. In the United States, the IPC/WHMA-A-620 is the industry standard for wire harness assembly. For applications targeting international markets, you might need to use the following as your guideline.

• European Committee for Electrical Standardization (IEC)
• International Commission for Rules for Approval of Electrical Equipment (CEE)
• International Electrotechnical Commission (CENELEC)

Components that make up a Custom Wire Harness

Wire harness assembly comprises wires, cables, terminations, connectors, sleeves, and other things that help organize these parts in an extensive electrical system. 

Wiring harness wires

Wires are the main component of wiring harnesses. There is either a single conducting strand of aluminum or copper or can be braided or stranded wires. The use of different wires depends on the needs of the project. 

Sometimes, you may also need different gauge wires in the same wire assembly to provide multiple functions. According to the AWG system, manufacturers use standard gauges in wire harnesses 10, 12, and 14.

In addition, standard wire colors and their functionality are:

Black wires: indicates a hot/positive current

White wires: indicates a negative current

Green wires: mainly used for ground wiring in residential applications

Red wires: work as a secondary line for hot/positive currents

Blue wires: designates a point of connection

Cables

The electrical industry uses different standard cables. These cables typically have a neutral, hot, and ground wire. Each of these wires twists and bonds together to form a single wire. The cable wires have PVC insulation or others to prevent shocks. Also, the color coding of insulation helps identify the wires.

Different cable standards help engineers design a system based on cable specifications. As a result, they save a lot of time and money rather than manufacturing the harness from scratch. UL-certified cable types include TPT, SPT-2, SVO, TST, SJE, and SJOOQ. 

Connectors

There are connectors available in different shapes and sizes, but there are specific connectors for a particular cable. For example, in a complex custom wiring harness, you can find socket-type connectors, dip connectors, d-sub connectors, and card edge connectors, along with ribbon cable connectors.

Terminations

When you terminate a cable at the connection point of equipment, wall outlet, panel, or any other device, you need to terminate it perfectly and safely. You can find endless terminations options, including insulated or non-insulated spades, ring terminals, hook terminals, and others.

The tools & parts you need for building a wiring harness

While building a wire harness, you need to make several electrical connections for which you need to do splicing and termination. As a result, you may require some tools to get the job done. 

Electrical tapes and cable ties 

These will help shield the wires and cables from abrasion, essential for preventing electrical fires.

Soldering iron

You can use it for splicing wires. Though the process is time-consuming and requires skill, it’s much more professional and robust. You may also need heat shrink tubing to complete the process.

Wire cutters and crimpers

Other than soldering iron for splicing wires, you may also need to make a crimp connection. Thus, you may also need a wire cutter and crimper. You can also take an automatic wire stripper.

A helping hand station

You may also need a helping hand station where a clamp holds the wires together while working.

A dielectric grease

You may also want a dielectric grease for installing the wire harness.

A workbench

You will need a workbench with vast space to extend the harness.

Build an automotive wiring harness at home

Running the wiring harness through the vehicle is the most daunting task. There are chances of cuts and bruises while hooking wires and different dash components. So, it’s better to be safe. Always wear your safety glasses and gloves while working. Further, there are high chances of electrical shocks and fire. So, always keep a fire extinguisher with you. Also, ensure that you do not supply any power to the harness while working; otherwise, it can be hazardous. Also, take precautions while moving parts with sharp or dull edges, as it can damage the casing.

Study a schematic

While building wire harnesses, you will have to refer to the schematics or wiring diagrams. With the right schematics, you can be sure that you are making the right connections. Also, it helps you to avoid tapping harmful wires in power devices. The cable harness diagram also saves time if you study them before building.

Lay out your harness

If you are replacing an old harness, it can work as a reference point for building a new one. So, lay it out and try to understand wire lengths and routing.

Decide where to mount the fuse block.

Mainly, it will not mount at the old location, thus throwing off the measurements for some wires.

Take note of routing in the car.

You need to learn where to run the wires before making connections. When you know this, you can cut and splice the wires without any potential mistakes. It is the most annoying job in the whole wire harness-building process, whether a short harness or a long one. You can take the help of the factory wiring diagrams. Some universal-style harnesses come with proper labeling to make things easier.

Replicate your wire routing on the workstation

Create a replica of the wiring diagrams in the car on your workstation. With this, you need not run back to your vehicle a hundred times, and also, you will get much more accurate results. Simply trace the dimensions and lay the wire on them.

Separate, Protect, and Secure

Separate all the wires before splicing. Add wire tapes, looms, or sleeves to prevent the tangling of the wires. Once done, take the harness to the car for the last mockup.

Source old connectors 

Now, you can cut connectors from your old harness and put them in the new one. However, start one by one; otherwise, it will confuse you. Take notes in a notebook, or draw pictures or label wires to clarify things. 

Instead, you can also use crimp connectors, but the finish could be better.

Strip the wire

Take a wire stripper and remove a small portion of the wire insulation from one end. Remember, you must attach wires to terminals and cut them according to the terminal size.

Cut the heat shrink

Cut a heat-shrink tubing longer than the stripped wire length, and insert this tubing over the unstripped part of the wire.

Attach a terminal

1. Pick a terminal, put its seam into the pliers, and crimp it slightly.
2. Insert this terminal onto the wire and squeeze the wire and terminal with the pliers.
3. Apply enough force to crimp the wire and not damage them.

Cover the wire

Next, pull the shrink tubing over the crimped edge of the wire and the terminal. Make sure that the tubing closes the two parts completely and tightly.

Shrink the tubing

In this step, you need a heat gun. Switch on the gun set the required temperature, and let it warm. Now direct the hot air from the gun over the heat shrink tubing.

Are you installing a new car stereo? Do you know what you need to achieve this? First, you need to know the aftermarket car stereo wire color codes. Secondly, ensure the wiring harness adapter identifies your vehicle specifications. The good news is that the CEA has all the color coding standards listed. All you need is to connect the proper wires to the correct terminals.  This article will provide further insight into wire harness colors in a stereo harness. So, read on!

What’s A Stereo Wire Harness?

You can describe a harness as an adapter. A stereo harness is a vital adapter that assists in installing an aftermarket stereo in the car. Stereo harnesses are readily available in the market and are surprisingly affordable. The only challenging part is choosing the correct wiring harness for the car and stereo.

To ensure your stereo harness works, it has to match your car specs and the stereo. If you find it hard to choose the proper stereo harness, you can use online tools to simplify your work. 

Over the years, the wiring harness has evolved and can now handle complex wiring and data transfer, such as bypassing built-in amplifiers and stretching the length of a wire. 

Specialized Harnesses For Stereo

Diversity in wiring systems has made it hassle-free for individuals. There are varieties of specialized harnesses in the market to choose from. Here are some areas harnesses may assist you:

Extension Harnesses

Some cars have stereo connectors at a distance from their stereo. Similarly, there are some cars with connectors in their trunks. So, this is where extension harnesses come in handy. Experts designed extension harnesses with longer cables. 

The more advanced extension harnesses give you room for adjustments suited to your needs.

Safety Alarm Retainer 

Many vehicles have safety alarms integrated into the factory stereo. Therefore, the alarms disappear when replacing the stereo, which is dangerous. The good news is there are specialized harnesses designed to keep the sound alarms working after installing a new stereo. 

Programmable Harness

Today’s modern vehicles have unique features inbuilt into factory radios. These features make wiring more complicated. Examples are FORD sync, GM OnStar, Chrysler Uconnect, and many more. 

You will lose the inbuilt features when replacing the factory stock radio. But it would be best if you didn’t worry; the world has become advanced, and you can still enjoy these features despite replacements. There are now better harnesses that you can program with these features.

You’ll spend an extra cost on the advanced harnesses, but it’s worth it.

Amp Bypassing

There are cases when your car’s stereo system may be separate from the amplifier. Therefore you can use your amplifier with your aftermarket stereo.

Suppose your aftermarket stereo comes with an amplifier, the better for you. You can bypass the factory amplifier using a specialized harness. 

How Do I Find The Right Wiring Harness?

Finding the correct wiring harness is hassle-free. You only need a little information, and you are set. It mostly has to do with your vehicle. Therefore, look out for the following in your vehicle:

• The year
• Make 
• Model
• Whether your vehicle has a factory-amplified system
• Whether your vehicle has an aftermarket radio.

You don’t need a wire harness if your vehicle has an aftermarket radio because dealers use a wiring harness when installing an aftermarket stereo.

On the other hand, if you have a factory amplified system, you’ll need a specialized harness. The goal is for it to provide a signal to your factory amplifier. 

How To Install An Aftermarket Stereo Using Harness?

Before you begin your installation, remove the old stereo. Secondly, disconnect the ground wire, which is usually the black terminal of the battery, i.e., the negative wire. Failing to disconnect the ground wire may cause damage to your stereo system or yourself. 

The next step will be to connect the new aftermarket wiring harness adapter. Remember, you checked that it’s the best fit for your car. Now, connect the new radio plug to the wiring harness adapter. The setup allows you to plug the car’s wiring harness into the stereo. 

All you need to do is match the stereo wiring colors with the colors on the harness adapter. Matching the wrong color wires will only give you more headaches. 

Important: The circuit breaker should be off when working with electrical wires. Also, consider what to consider before choosing your wire harness components beforehand. 

What Color Wires Go Together In A Car Stereo?

In the day, vehicle manufacturers used color codes that varied by vehicle model or brand. But, nowadays, they use standardized car stereo wire colors when manufacturing cars. Typically, you should find your car’s stereo wiring diagram providing you with an aftermarket stereo. If you don’t find these, use the aftermarket radio wire colors. 

The electrical wires are available in categories, with each color’s purpose:

Wire Harness Labeling: Ground wire

It is a single black wire. It offers additional parts for electrical circuits to flow to the earth. It’s a safety wire.

Wire Harness Labeling: A power wire
