7. Control By Universal DMX Controller
7.1 Connection
1. At last unit, the DMX cable has to be terminated with a terminator. Solder a 120-ohm
1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a 3-pin XLR-plug and plug it in
the DMX-output of the last unit.
2. Connect the unit together in a “daisy chain” by XLR plug cable from the output of the unit
to the input of the next unit. The cable cannot be branched or split to a “Y” cable. DMX
512 is a very high-speed signal. Inadequate or damaged cables, soldered joints or
corroded connectors can easily distort the signal and shut down the system.
3. The DMX output and input connectors are pass-through to maintain the DMX circuit,
when one of the units’ power is disconnected.
4. Each lighting unit needs to have a DMX address to receive the data by the controller. The
address number is between 0-511 (usually 0 & 1 are equal to 1).
