Building a serial DMX-chain
z
If you are u sing the st andard DMX-controllers, you can connect the
DMX-output of the controller directl y with the DMX-input of the first fixture in
the DMX-chain. If you wish to co nnect DMX-controllers with other
XLR-outputs, you need to use adapter cables.
z
Connect the DMX-output of the first fixture in th e DMX-chain with the
DMX-input of the next fixture. Always connect output with the input of the next
fixture until all fixtures are connected.
z
If you use a controller with 5 pins DMX connector, you need to use a 5 to 3
pins adpter
z
At last fixture, 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 pins
XLR-plug and plug it in the DMX-output of the last fixture.
z
Connect the fixture tog ether in a dai sy chain by XLR plug cable from the
output of the fixtur e to t he input of the ne xt fixture. The cable ca nnot be
branched or s plit to a Y cable. DMX 512 is a v ery high speed signal.
Inadequate or damaged cables, soldered joints or corroded connectors can
easily distort the signal and shut down the system.
z
The DXM output and input connectors are pass-through to maintain the DMX
circuit, when power is disconnected to the unit.
z
Each fixture needs to have a DMX address to receiv e the data from the
controller. The DMX address number which could be read from rear panel of
each fixture is between 000~511.
z
The end of the DMX 512 chain should be terminated to reduce signal errors.
