The Mania SCX500’s data connections are XLR type, wired with pin 1 to
ground, pin 2 to signal - (cold), and pin 3 to (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.
