This section describes how to connect fixtures to a controller.
RECOMMENDED CABLE
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.
CONNECTIONS
The Acrobat’s XLR data sockets are wired with pin 1 to ground, pin 2 to signal -
(cold), and pin 3 to signal + (hot). This is the standard pin assignment for DMX
devices.
One or more adaptor cables may be required to connect the Acrobat to the
controller and/or other lights because many devices have 5-pin connectors and
others may have reversed signal polarity, that is, pin 2 hot and pin 3 cold.
