Dmx-512 Connection / Master/Slave Connection - Futurelight MH-420 Manual Del Usuario

DMX-512 connection / Master/Slave connection

Controller operation
Master/Slave operation
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:
If you are using the recommended FUTURELIGHT-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.
Building a serial DMX-chain:
Connect the DMX-output of the first fixture in the DMX-chain with the DMX-input of the next fixture. Always
connect one output with the input of the next fixture until all fixtures are connected.
Ω
Caution: At the last fixture, the DMX-cable has to be terminated with a terminator. Solder a 120 resistor
between Signal (–) and Signal (+) into a 3-pin XLR-plug and plug it in the DMX-output of the last fixture.
Master/Slave-operation
The master/slave-operation enables that several devices can be synchronized and controlled by one master-
device.
On the side panel of the MH-420 you can find an XLR-jack (DMX Out) and an XLR-plug (DMX In), which can
be used for connecting several devices.
