1. If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pin adapter-cable.
2. 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.
3. Connect the unit together in a `daisy chain` by XLR plug from the output of the unit to the input of the next
unit. The cable can not be branched or split to a `Y` cable. DMX512 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.
4. The DMX output and input connectors are pass-through to maintain the DMX circuit, when power is
disconnected to the unit.
5.
Each lighting unit needs to have an address set to receive the data sent by the controller. The
address number is between 0-511 (usually 0 & 1 are equal to 1).
6.
The end of the DMX512 system should be terminated to reduce signal errors.
7.
3 pin XLR connectors are more popular than 5 pin XLR.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
