DMX-512 CONNECTION
If you are using a standard DMX controller, you can connect the DMX output of the controller directly to the DMX input of the
first unit in a DMX chain. Always connect the output of one unit with the input of the next unit until all units are connected.
5-pin XLR DMX Connectors.
Some manufactures use 5-pin DMX-512 data cables for DATA transmission in place of 3-pin. 5-pin DMX fixtures may be
implemented in a 3-pin DMX line. When inserting standard 5-pin data cables in to a 3-pin line a cable adaptor must be used.
The chart below details a proper cable conversion.

At the last fixture, the DMX cable has to be terminated. Solder a 120 Ohm resistor between signal (-) and signal (+) into a 3-pin
XLR connector and plug this into the DMX output of the last fixture in the chain.
