DMX Control Wiring and Termination

Follow the DMX termination kit instructions provided with the product to terminate the
control wiring.
DMX termination is made to J8 and J9 on the termination board. Use the DMX Pass-Thru if you
are daisy-chaining to another panel or DMX device.
After completing the DMX data connections, you must
properly terminate the DMX line using the termination
switch (S2) on the relay panel termination board. Data
termination eliminates reflections at the end of the
DMX data run.
Note:
The RDM position is not used.
