D. 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 (usually 0 & 1 are equal to
1).
•
The end of the DMX512 system should be terminated to reduce 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 (+)
