DMX OPERATION 6
This section describes how to set up and connect the MX-4 for operation with DMX
controllers.
DATA CONNECTION
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 MX-4’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 MX-4 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.
