Unit 1 Unit 2 Unit 3 Unit 4
1.
If you using a controller with a 5 pin DMX output, you need to use a 5 to 3 pin adapter-‐cable
2.
The last units DMX cable has to be terminated with a 120 ohm 1/4W resistor between pin
2(DMX-‐) and pin 3(DMX+) of a 3-‐pin XLR-‐plug and plug it in the DMX-‐output of the last unit.
3.
Connect the units together in a `daisy chain` by using a DMX cable from the output of the unit
to the input of the next unit. The cable can not branched or split to a `Y` cable. The DMX
output and input connectors are a “pass-‐through” type to maintain the DMX circuit even if
one of the units power is disconnected.
4.
Each fixture unit needs to have an address set to receive the data sent by the controller. The
address number are between 1-‐512
5.
The end of the DMX 512 line system should be terminated to reduce signal errors.
