CONNECTION

A reliable data connection begins with the right cable. For best results, use cable

specifically designed for RS-485 applications, available from your Martin dealer.

CONNECTIONS

The data sockets are wired with pin 1 to ground, pin 2 to signal - (cold), and pin 3

to signal + (hot) for compatibility with DMX devices. One or more adaptor cables

as shown below may be required for connection to the controller or other lights.

To connect the data link

1 Connect a cable to the controller’s data output. If the output socket has a 5

pins, use a 5-pin male to 3-pin female adaptor. Lead the cable to the first

fixture and plug it into the data input.

2 Connect the output of the fixture closest to the controller to the input of the

next fixture. If connecting to a fixture with reversed-polarity (pin 3 cold),

insert a phase-reversing cable between the two fixtures. Continue connecting

fixtures output to input. Up to 32 devices may be connected on a serial link.

3 Terminate the link by inserting a male termination plug (P/N 91613017) into

the data output of the last fixture. A termination plug is simply an XLR

connector with a 120 ohm, 0.25 W resistor soldered across pins 2 and 3.
