1. 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.
2. Connect the unit together in a "daisy chain" by XLR plug 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 1-512.
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.
5.2 Address Setting
If you use a universal DMX controller to control the units, you have to set DMX address from 1 to
512 so that the units can receive DMX signal.
Press the MENU button to enter menu mode, select DMX Address, press the ENTER button to
confirm, the present address will blinking the display, use the UP/DOWN button to adjust the
address from 001 to 512, press the ENTER button to store. Press the MENU button back to the last
menu or let the unit idle 30 seconds to exit menu mode.
Please refer to the following diagram to address your DMX512 channel for the first 4 units.
