Dmx- 512 Connection, Master/Slave Connection - Elation COLOR SPOT 150 User Manual

4.6 DMX- 512 connection, master/slave connection

The wires must not come into contact with each other, otherwise
the fixtures will not work at all, or will not work properly.
Only use a stereo shielded cable and 3-pin XLR-plugs and connectors in order to connect the controller with the
fixture or one fixture with another.
Occupation of the XLR-connection:
Building a serial DMX-chain:
If you are using the standard controllers, you can connect the DMX-output of the controller directly with the DMX-
input of the first fixture in the DMX-chain. If you wish to connect DMX-controllers with other XLR-outputs, you
need to use adapter-cables.
Connect the DMX-output of the first fixture in the 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.
Caution: At the last fixture, the DMX-cable has to be terminated with a terminator. Solder a 120 Ohm resistor
between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the DMX-output of the last fixture.
Building a master/slave-chain:
Connect the DMX-output of the master fixture in the data-chain with the DMX-input of the first slave. Always
connect output with the input of the next slave until all slaves are connected (up to 9 fixtures).
Caution:It's necessary to insert the XLR termination plug (with 120 Ohm) into the input of the master fixture and
into the output of the last slave fixture in the link in order to ensure proper transmission on the data link.
