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.

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.
