DMX operation
To connect the data link
1 Connect a data cable to the controller’s data output. If the controller has a 5-pin
output, use a 5-pin male to 3-pin female adaptor cable (P/N 11820005).
2 Lead the data cable from the controller to the first fixture and plug it into the
data input.
3 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.
4 Continue connecting fixtures output to input. Up to 32 devices may be
connected on a serial link.
5 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.
1-CHANNEL DMX OPERATION
The 1-channel DMX mode provides simple remote activation of the MX-4’s stand-
alone programs plus blackout and strobe functions. The 1-channel functions are
shown in Table 5. Each fixture runs its own program and therefore cannot be
synchronized with other fixtures.
