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 one of the units’ power is disconnected.
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 (+),
Pin4/5: Not used

4. How To Control The Unit
Three ways to operation:
A. Master/Slave operation
B. Easy controller CA-8
C. Universal DMX controller
4.1. Master/Slave operation
The unit can be linked together in daisy chain as many as you need in master/slave
mode, the first unit will control the others to give a coordinate automatic light show
and it’s good for instant shows.
In Master/Slave mode refer to the DMX settings below:
Master unit: Set DIP switch 1-9 to OFF.
Slave units: The DMX start address may set to any value but 0.
Î 4-Light show
Set dip switch 1-9 to OFF for the first unit which has nothing in its DMX input jack.
Set the DMX address of other units to 1,4,7 or 10 when the dip switch 10 ON, or set
the DMX address of other units to 1,5,9 or 13 when the dip switch 10 OFF, then the
units (slave) will follow the first unit (master) to run built-in program for 4-Light show.
The units which don’t set as mentioned earlier will run as slave 1.
Dip switch 10 OFF
Slave 1:dip / on: #1 (=1)
Slave 2:dip / on: #1,#3 (1+4=5)
Slave 3:dip / on: #1, #4 (1+8=9)
Slave 4:dip / on: #1, #3, #4 (1+4+8=13)
Dip switch 10 ON
Slave 1:dip / on: #1 (=1)
Slave 2:dip / on:,#3 (=4)
Slave 3:dip / on: #1, #2, #3 (1+2+4=7)
Slave 4:dip / on: #2, #4 (2+8=10)
