A quick guide to what you really need to know about DMX DMX Wiring Guide. Wire color is manufacturer specific. Use connector to determine pin number for each wire. XLR Pin. Wire Color and. Wires 4 and 5 are commonly used in non-DMX equipment to carry power-over-Ethernet. Best practice for DMX only wiring installers is to cap and turn back this pair to avoid accidental damage to equipment.

The use of RJ45 connectors for DMX equipment should only be done with caution, and should be restricted to patch bays in access-controlled rooms. RJ45 connectors and Cat5 cable should not be used to connect portable equipment. YouTube Twitter. All wiring must be in a continuous run and daisy-chained. Star wiring is only allowed in conjunction with an opto-splitter. Cable shield may be grounded at one end only, preferably at the control console.

Maximum cable length is 1, ft when used for DMX only Maximum cable length for systems incorporating RDM is ft due biblical meaning of insects timing constraints Receiving devices have male connectors, transmitters have female.

RJ45 connectors may be used with Cat5 cable, for permanent wiring. Cat5 UTP cable may be used inside metal conduit. Use Cat5 STP when installed in raceways. We strongly recommend wires 7 and 8 both be connected even. Category wire is not recommended for loose or temporary cabling.

Go to top.ESTA does not define a maximum run length for DMX over Cat5 since many factors will affect the maximum run length such as number of devices, number of splices in the cable, the strength of the DMX transmitter sif Remote Device Management RDM is being used, and sources of interference. Please note that the technical requirements, such as run-length and topology for other networking technologies, such as Ethernet, should be considered if using the installed cable for another networking technology in the future is anticipated.

Cat5 or equivalent is not preferred as a portable cable since it is not as rugged as other DMX cables. Male RJ45 connectors are especially prone to breakage over repeated re-connections. These can be, for example, headers specifically designed for the size of conductor or RJ45s.

Stripping the wire and then placing it in a solder cup or screw terminal is an easy invitation to conductor breakage. ANSI E1. External user accessible IEC 8-position modular connectors are permitted only on patch and data distribution products and only when permanently installed in controlled access areas. Note: Examples of not normally accessible or controlled access areas include a locked electrical room or control booth, provided those who need access have a key or lock combination available.

Note 2: Pin 8 should be wired as signal common even if pins 3 and 6 are NOT wired so that both conductors 7 and 8 are at equal potential. Pins 4 and 5 may carry voltages outside the EIA range in telecom applications e.

Pins 4 and 7 may carry voltages outside the EIA range in other applications e. Because of these various uses, misplugging unlike systems could cause serious damage. To the best of our information, CK uses the following:. Suggested Wiring Practices Do not run data signals next to or in the same conduit as high power sources. If necessary to be near these sources cross over them at 90 degrees or keep as much parallel distance between them as possible. Use IDCs for all Category 5 cable applications.

Plenum cable in plenum applications and also where physical damage may be a concern and conduit is not practical. Common Reference for Data 1 0v. Common Reference for Data 2 0v.When I first began working in this industry, I had no idea how to fix cables. I left that to highly paid professionals or just threw the cables away. I was scared of soldering, but I later found out that I had nothing to be afraid of. In fact, many DMX cables are a easy and quick fix.

If your connector is physically broken, you also will need new plugs for your cable. If it just came de-soldered, you may be able to just re-solder it back in place using your soldering iron, without doing any wire stripping. This is where I like to use my cable tester as a helper — I plug the cable into the tester to hold the plug upright as I hold the wire and soldering iron and get down to business. Use your soldering iron to heat up the wire and the receiver until they come apart.

You may need to pull on it gently once you see the solder liquefied.

Once you get the outer layer off, you can cut off the old soldered ends and re-strip the wire using your wire strippers. Before you begin, make extra sure that the connectors boot and strain relief are on the wire before you begin!

It stinks to finish and realize you forgot this! Many plugs nowadays have a strain relief that you can put on after soldering, but you definitely need to have that boot on there before soldering. Hold up your wires and iron to your plug and use the iron to heat the receivers on the plug, not the wire. You want to get the metal cup or strip hot enough that it melts the solder both on it and on the wire to fuse them together for the best connection.

Adaptors, Connectors

Once everything is visibly liquefied, you can carefully release the iron and hold everything in place. I also usually have a fan running while I do this or blow on the connection to help it cool faster.

DMX systems consist of a single transmitting or 'master' device plus between one and 32 receiving devices. For portable devices such as LED or automated fixtures, typically a receiver will use a five pin XLR type connector, with a male connector used for the DMX input to the device, and a female connector used for the DMX thru connector.

DMX should always be daisy chained from device to device. It should never be "Y-Split" as this will reduce the reliability of communication. It is not truly important which is used. Inwe started using a three pin removable header with both screw connector type and punchdown type connectors available with devices such as the Response MkII Gateways.

These should only be used in patch panel type scenarios; most RJ45 connectors are not rugged enough to be used in the field for data connections. They are very sensitive to the ingress of dust, and are also mechanically weak.

DMX uses a cable consisting of two twisted pairs plus a shield to carry data. The cable must be specifically impedance matched for the digital DMX signal. Network cable Cat5, 5e or 6 cable may be used to carry DMX in an installation; however special consideration must be given to shielding and termination. Under no circumstances should solid core cable like Cat5 be terminated into a screw down connector. Belden is a two pair cable, which allows for a spare pair for 'out and back' type terminations if needed.

Other cables may be acceptable; ETC project management can help with recommendations of other cables. ETC also maintains a cable cross databasewhich has a list of approved and unapproved cables for DMX and other signal types. The original and versions of the DMX standard specify ohm or ohm 1- or 2-twisted pair shielded cable suitable for use with EIA ohm and EIA ohm electronics. Cabling DMX uses a cable consisting of two twisted pairs plus a shield to carry data.

The basic troubleshooting steps are: Is the DMX terminated? Many people treat the fitting of a termination resistor as optional; but although DMX may work without it, in this state a small change to the DMX network, like adding another cable, may stop the system from working or cause intermittent effects like flicker of dimmers, twitching of moving lights and so on.

Adding termination can help eliminate these effects Is the cabling OK? DMX may continue to work partially even under extreme conditions like having one half of the data pair broken.

If you have a fixture which is misbehaving, take it and connect it directly to the DMX source with a short jumper cable. If it now works there is an issue with your cabling to be investigated Is the device OK? Damage to device DMX receivers can occur in many ways; lightning storms are a common problem. Some devices do not support the full range of timings. In order to help troubleshoot this, ETC products feature output speeds that can be altered to help slower devices.

Advanced Troubleshooting: Are both ends of the cable grounded to the same ground reference? DMX is a differential signal with the common pin 1 providing the reference for when the signal is high or low. Depending on the design of the DMX device, the common may reference Earth ground through the power supply or be an isolated ground reference. In some cases where one end of the DMX chain is referencing Earth ground while the other is isolated, the potential on the Earth ground can cause the reference point to float and can appear that there is no control or flickering control.

In these instances, as a troubleshooting step, try lifting disconnecting common pin 1 from one end of the DMX line. If this resolves the issue, an optical isolator is recommended to be placed in line to maintain proper DMX circuit design while correcting for the difference in potential on ground.More than just connectors.

This is very important. If they were, and if you were to pickup two DMX connectors that have different earth potentials you could get a very nasty or fatal shock. That "spare" data pair referred to hides a multitude of sins. Pulsar who make the electronics for Clay Paky stepped into a right hornets nest with their public announcement of their non-compliance. However, it is possible a lot of good may come from this.

The 4 pin XLR is used mostly by scrollers and colour changers to deliver both control and power to a lighting accessory. The 3 pin XLR is used mostly by moving lights. Of course, as the XLR3 was never standardised as a "proper" DMX connector, there is no "proper" pinout, so of course, both variations are used DMX is a bit fussy about the cables it is shoved down.

Lighting control cables have to satisfy the conflicting requirements of being physically tough, to survive life on the road, and also electrically impressive to conduct and contain a signal that is transitioning at speeds over an order of magnitude faster than traditional RS That said, DMX will survive being conducted along almost any twisted pair cable, and I have even seen DMX sucessfully being run down two cord zip lighting flex.

However it is likely that such installations will be more problemsome than one done using the correct cables. The theoretical length limit of a DMX cable from source to final terminator is 1KM, about feet. However to work reliably at this distance you must have perfect source, termination, and cable of adequate cross section. Being pragmatic, it's best not to run a show at the limit of technology, and choose a smaller 'maximum' for your own peace of mind, say feet. Pin Usual colour Usage Notes 1.When it comes to DMX Lighting, you can ask 5 different people about which connectors to use and probably get 5 different answers.

To take it a step further, you might find that your fixture takes 2 or more different input connections! This can be confusing and there are lots of contradicting sources out there.

At the time of this article's writing, no such adoption has ever occurred, and over time, cost among other reasons, has driven many manufacturers to opt for 3-pin XLR cables eerily similar to a microphone XLR cable or even the lower-cost, smaller still, RJ45 ethernet-style jack. As of now, connectors and cables are available in a wide array of types, sizes, and fittings, from 3-pin XLRs to 3-port terminal blocks.

With all these connectors and cables, it's important to know that you're using the right cable and have the this. If you'd like to skip ahead to the pinouts, you can do so here.

When setting up your system, it's important to have the right equipment and wiring, so we'll cover that here. You may be wondering why you can't use a Microphone cable with DMX. The answer is that you can. It may work in some situations and not in others, or it might work until you begin adding more fixtures, or it might work but produce some strange effects, such as strobing and flickering. If you happen to find yourself in this boat, we've got you covered with tips on troubleshooting DMX issues.

DMX cable, on the other hand, is created to carry the much higher bandwidth and frequency digital signal of DMX and has much higher impedance.

With DMX, there are tons of packets of data traveling through the cable carrying crucial lighting data that a microphone cable might not be able to effectively relay. So what is the proper cable?

According to the DMX specification, the cable must be ohm to meet the standard. This is a large difference from the ohms you would find in an audio cable. So as long as you are using a cable up to the standards, you should be just fine. You can find the most-current standards, maintained by ESTA, here. With the right DMX cable at your disposal, there are a plethora of ways to make the connection CueServer supports up to 7 different standard connection types alone!
