Troubleshooting Troubleshooting Problem Probable cause(s) Remedy Fixture is completely dead. No power to fixture. Check AC mains power and connections. Internal circuit fault. Have faulty fixture serviced by Martin service technician. One or more fixtures resets correctly but responds erratically or not at all to the controller. Fault on data link. Inspect connections and cables. Correct poor connections. Repair or replace damaged cables. Data link not terminated. Insert termination plugin output connector of the last fixture on the link.

Unplug XLR in and out connectors and connect them directly together to bypass one fixture at a time until normal operation is regained. Have faulty fixture serviced by Martin service technician. XLR pin-out on fixtures does not match (pins 2 and 3 reversed). Install a phase-reversing cable between the fixtures or swap pins 2 and 3 in the fixture that behaves erratically.
