Cables and Connections

RJ45

Inspired by PoE (Power Over Ethernet), we bring low voltage to our fixtures using Cat6 22 AWG cable.

Just like AC system, cable gauge and length have a vital impact on the stability and efficiency of Low Voltage systems. We use the shortest twisted pair of conductors within Cat6 wires which reduces the loss power transmission and color rendering (RGB).

To minimize the impact of cable length, refer to the pinout chart and adhere to maximum recommended cable run length per category wire.

You may also use Cat 5 or regular Cat6 cables, but this will limit your the distance you can have between the lights and the drivers.

Cat 5 24 AWG conductor Maximum length: 200’ or 45m

Cat 6 23 AWG conductor Maximum length: 300’ or 75m

Cat 6 22 AWG is the recommended option.

If you expect runs greater than 300’/75m consider a second electrical room.

RJ45 Loop Terminator

A bridge is necessary to enable the DC loop. The last fixture on each line requires a terminator. This terminator is very different than a DMX terminator as it has no resistor, simply a bridge to create the required loop in VDC.

Each Colorbeam Lighting fixture comes with a RJ45 terminator.

Note

Please be aware that the Loop Terminator that comes with our RGB lights, may not work properly with Bi-White lights.

DMX Wire

The DMX Wire is a 120 Ohm cable, used to control the noise on the DMX bus. You will just need to make sure the proper pins connect to each other. In other words, D+ to D+, D- to D- and Ground to Ground. You will also need to make sure that when you connect devices together with the DMX Wire, that you connect from the DMX Out of a device to a DMX In of the next device in the chain (DMX bus). The order in which your devices are connected does not matter.

3 Pin Terminal Block

Note

Never use ‘T’s’, ‘Y’s’ or ‘star’ connection to split signal in DMX wiring. Just daisy chain the drivers or use a our DMX Amplifiers.

Note

If you are not using a proper DMX cable, we recommend using a shielded 24 AWG pair for runs no longer than 300’/90m and each DMX line should be terminated. This is to keep a strong data transmission over the DMX bus.

DMX Pinout

Note

We recommend not connecting more than 6 DMX devices on the same chain. If you need to connect more devices, you would best use a DMX Amplifier.
