DMX Networking Guidelines
If you are connecting more than one DMX fixture, it is imperative to properly configure the DMX network. Following the
guidelines below should reduce the possibility of networking errors.
1. Only cables intended for DMX operations should be used. Avoid DMX runs parallel to power cables, particularly those
from dimmer racks.
2. Fixtures and other devices in a DMX network need to be configured in a daisy-chain fashion. The use of DMX “Y” devices
or “twofers” is not advised.
3. You can use up to 32 Brightline DMX fixtures on a single DMX data line. If there are more than 32 units, the use of a
DMX repeater amplifier or splitter amplifier is required. A repeater amplifier is an electronic device that boosts the
DMX signal. A splitter amplifier is an electronic device that boosts the DMX signal and provides for multiple DMX
outputs from a single DMX input since using multiple DMX devices may cause signal degradation.
4. Brightline DMX fixtures are self-termina ng. No DMX termina on switch is required. (With most DMX devices, there is a
“DMX Thru/DMX Terminate: switch that is set to “Terminate” for the last device on the data line and set to “Through” for
all other devices.)
5. Brightline fixtures, like the majority of DMX devices, use 5-pin, XLR-type plugs wired according to table 1. Pins 4 & 5 are
not used, and so, on Brightline fixtures, are not connected to wiring. Pin 1 (shield) should be connected to earth ground
only at the control console.
Note: These guidelines will help the user configure most DMX networks. For more information, contact the manufacturer of the control console, or a DMX
manual. A useful DMX guide is “Recommended Practice for DMX-512” by Adam Benne e, co-published by PLASA in the United Kingdom and USITT in
North America.
