ATTENTION
Termination reduces signal errors and to avoid signal transmission problems and
interference. It is always advisable to connect a DMX terminal (Resistance 120 ohm 1/4W
between pin2 (DMX-) and pin3 (DMX+) of the last fixture).
1.
At the 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.
2.
Connect the unit together in a
“daisy chain”
plug the XLR cable from the output of the unit to the
input of the next unit. The cable cannot be 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.
3.
The DMX output and input connectors are pass-through to maintain the DMX circuit, when one of
the units’ power is
disconnected.
4.
Each lighting unit needs to have a DMX address to receive the data by the controller. The address
number is between 0-511 (usually 0 & 1 are equal to 1).
5.
The end of the DMX 512 system should be terminated to reduce signal errors.
6. 3 pin XLR connectors are more popular than 5 pins 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 (+), Pin4, Pin5 not used.
Address Setting
If you use a universal DMX controller to control the units, you have to set the DMX address from 1 to
512 so that the units can receive DMX signal.
