OPERATION

This section describes setup and operation with DMX controllers.

Important! Controller operation is disabled if stand-alone mode is enabled.

DATA CONNECTION

RECOMMENDED CABLE

Reliable data communication begins with the right cable. Most microphone cable

does not transmit digital data reliably over long runs. For best results, use shielded,

twisted-pair cable designed for RS-485 applications with low capacitance and a

characteristic impedance of 85 to 150 ohms. The minimum wire size is 0.2 mm (24

AWG) for runs up to 300 meters (1000 ft.) and 0.322 mm (26 AWG) for runs up

500 meters (1640 ft.).

Your Martin dealer can supply the right cable in various lengths.

CONNECTIONS

The XLR data sockets are wired 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 MiniMAC Maestro to

the controller and other lights if they have 5-pin connectors or reversed signal

polarity on pins 2 and 3.
