4.5 DMX512 Connection
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 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.
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 DMX 512 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 (+)
Pin 4/5: Not used.
