Connecting The Serial Data Link - Martin Mania SCX500 User Manual

applications. Your Martin dealer can supply suitable high quality cable in
various lengths.

Connecting the serial data link

The Mania SCX500's data connections are XLR type, wired with pin 1 to
ground, pin 2 to signal - (cold), and pin 3 to signal + (hot). This is the
standard configuration for DMX devices.
One or more adaptor cables may be required to connect the Mania
SCX500 to the controller and/or other types of fixture, because some
devices may have 5-pin XLR connectors, and others may have reversed
signal polarity (pin 2 hot and pin 3 cold). Connector polarity is normally
specified on the device or in the device's user manual.

To connect the data link:
1. Power all devices off.
2. If you are using a DMX controller, run a data cable from the DMX
controller's data output to the first fixture's data IN socket. If the
controller has a 5-pin output, use a 5-pin male to 3-pin female adaptor
cable (P/N 11820005).
3. If you are not using a DMX controller, insert a female DMX termination
plug (P/N 91613018) in the first fixture's data IN socket.
4. Plug a data cable into the OUT socket of the first fixture and the IN
socket of the next one. Continue connecting up to 32 Mania SCX500s
output-to-input.
5. Terminate the link by inserting a male termination plug (available from
your Martin dealer: 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.
