4. HOW TO CONTROL THE UNIT
( 1 ) By universal DMX controller
The DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.
A DMX512 system requires a controller, lighting equipment and cable. These are
connected together in a "daisy chain" with the terminator at the end. The cable cannot be
branched or split to a "Y" cable.
The terminator requires a 90-120 Ohm 1/4 Watt resistor soldered between two signal cables.
The DMX512 uses a very high-speed signal. Inadequate or damaged cables, bad solder joints or
corroded connectors can easily distort the signal and shut down the system. A reliable DMX512
system starts with good quality cables.
Each lighting unit needs to have an address set to receive the data sent by the controller. The
address number is between 0-511. The end of the DMX512 system should be terminated
reducing signal errors.
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 (+)
