Cables and Connections


(Category 5 or Category 6)

Inspired by PoE (Power Over Ethernet), we bring low voltage to our fixtures using Cat5 or Cat6 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 Cat5/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.

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

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

Cat 6 22 AWG is also a 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 CBNA fixture comes with a RJ45 terminator.

DMX Wire

The DMX Wire itself is has nothing special to it. 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


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.

To keep strong data transmission, we recommend using a shielded 24 AWG pair for runs no longer than 300’/90m and each DMX line should be terminated.

DMX Pinout


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.

DMX Terminator

A DMX terminator is used on the last device thru/output to close the line; it is simply a connector (male) with a 120 Ω (Ohm) resistor connected across data signal pair (D+ and D-) to match the cable’s characteristic impedance which absorbs signal reflections.

DMX Terminator


If some lights seem to be flickering randomly, you maybe getting some interference on the DMX cable. Try adding a DMX terminator with a 120 Ω (Ohm) resistor at the end of your DMX bus. The resistor will need to be connected to the D+ and D- pins.

The use of the DMX Terminator is highly recommend, but not mandatory.
