A reliable data connection begins with the right cable. Standard microphone cable
cannot transmit DMX data reliably over long runs. For best results, use cable
specifically designed for RS-485 applications. Your Martin dealer can supply high
quality cable in various lengths.
The FiberSource QFX 150’s data sockets are wired pin 1 to ground, pin 2 to signal -
(cold), and pin 3 to (hot). This is the standard pin assignment for DMX
devices.
One or more adaptor cables may be required to connect the fixture to the controller
and other devices because many devices have 5-pin connectors and others may have
reversed signal polarity, that is, pin 2 hot and pin 3 cold.

1 Connect a data cable to the controller’s data output. If controller has a 5-pin
output, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005).
2 Lead the data cable from the controller to the first fixture and plug the cable
into the data input.
