Echo Relay Panel Feedthrough Installation Manual
DMX Control Wiring and Termination
DMX wire preparation will vary with the type of wire and termination kit being utilized. Please
refer to the instructions provided with the DMX termination kit for specifics on the wire
preparation. DMX termination is made to J8 and J9 on the termination board.
After completing the DMX data connections, you must properly terminate the DMX line using
the termination switch (S1) on the relay panel termination board. Data termination eliminates
reflections at the end of the DMX data run.

Connect Emergency Contact
The Echo Relay Panel Feedthrough can connect to an external
emergency circuit. Emergency can be triggered by a normally
open or normally closed contact input. In addition, the relay panel
optionally offers a +24Vdc (maximum 25mA) Emergency Out that
provides a feed to a lamp or LED, indicating emergency activity.
