Building a serial DMX-chain
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.
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.
If you use a controller with 5 pins DMX connector, you need to use a 5 to 3
pins adpter
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.
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.
The DXM output and input connectors are pass-through to maintain the DMX
circuit, when power is disconnected to the unit.
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.
The end of the DMX 512 chain should be terminated to reduce signal errors.
