S1. If there is no DMX signal to Dimmers or Lighting Fixture
- Is the DMX connector inserted onto the board?
- Is it the correct DMX connector or Artnet Port RJ45, it might be in the wrong input DMX A or DMX B.
- Check the DMX connector , is any of the wires disconnected
- Check the cable, Is it damaged? Do you have connection to the Dimmer?
- Is the Power for the dimmers ON?
- Is the MCBs Turned ON for the channel
- On the Lighting Board- can you go to Super User mode and set the DMX patch to Default mode (DMX address 1 to Dimmer channel 1)
- Is the Cable connecting from the Lighting Board to the dimmers tested?
- If there is a DMX Splitter in the system?,
- Is there power to the DMX splitter?
- Is the Connections to the Splitter correct, DMX IN and DMX outs?
- Can you test the Splitter or bypass the Splitter for the test.
- Is the DMX cable wire damaged or has the wire been disconnected from the soldering points ( please check both ends, literally by opening the connectors, also at the DMX splitter)
- Please change the connection to another dimmer or Lighting Fixture , it could be that the existing dimmer or lighting fixture's DMX PCB is faulty.
- If there are a few dimmers in the system, the dmx wires are wired in a daisy chain method. There could be a problem with one of the dimmers's DMX circuit. Try unplugging the dmx wiring and bypassing each dimmer to isolate the faulty dimmer.
- Is there a 120ohm Termination resistor at the end of the DMX circuit
