Why does my Martin MAC TW1 reset but respond erratically?

If your Martin Lighting Equipment resets correctly but responds erratically, the issue could stem from several factors. First, inspect the data link connections and cables for any damage or poor connections, and repair or replace as necessary. Ensure the data link is terminated by inserting a termination plug in the output jack of the last fixture on the link. Check the fixture's DMX addressing and ensure it matches the controller and that the fixture is set to the correct DMX mode. If problems persist, try bypassing one fixture at a time to see if one of them is defective. Another potential cause is an XLR pin-out mismatch; install a phase-reversing cable or swap pins 2 and 3 in the fixture that behaves erratically.
