Troubleshooting
Setting the DMX Address
LED fixture responding incorrectly
• Ensure all wiring connections are correct. Reversing the Data + and Data - will cause lights to flicker
and not respond to controller:
• Check power connections of all components (drivers, DMX decoders/fixtures, DMX controller).
• Ensure a compatible constant voltage driver is installed.
• Ensure the driver and DMX fixture(s) have the same voltage specifications (12V & 12V, or 24V & 24V).
Fixture does not dim • Ensure desired address is selected before changing brightness.
Fixture is flashing or flickering
• Verify a compatible constant voltage driver is installed.
• Ensure all connections are properly secured.
Prior to troubleshooting, ensure a compatible system is installed. Verify compatible fixtures, drivers, controls and additional components were specified correctly.
Use the 3 buttons and digital display to adjust the values of the DMX address (Fig. 1). The
decoder will control up to 512 channels. Once an address is selected, the remaining 3
channels will be utilized digitally. For example, if the decoder is addressed to 001 on the
display then CH1 – 001, CH2 – 002, CH3 – 003, CH4 – 004.
