6.1 DMX512 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 can only be used in series and cannot be
connected in parallel. 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.
