Connection Of The Dmx Line; Construction Of The Dmx Termination - Luxibel LX119 User Manual


When all devices have the same address, all the units will "listen" to the control signal on one
particular channel. In other words: changing the settings of one channel will affect all devices
simultaneously. If you set individual addresses, each device will "listen" to a separate channel
number. Changing the settings of one channel will only affect the device in question.
Example of a configuration with 8 channels:
number of start address
channels
8
DMX address 33

Connection of the DMX Line


When applicable, connect an XLR cable to the female XLR output of a controller (not incl.) and the
other side to the male XLR input [3 or 4] of the device. Multiple devices can be linked through serial
linking. The linking cable shall be a dual core, screened cable with XLR input and output connectors.

Maximum recommended serial data link distance is 500 meters (1640 ft). Maximum recommended
number of devices on a serial data link is 32 devices.

Construction of the DMX Termination


A DMX terminator is recommended for installations where the DMX cable has to run a long distance
or is in an electrically noisy environment (e.g. discos). The terminator prevents corruption of the
digital control signal by electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω
resistor between pins 2 and 3, which is then plugged into the XLR output socket of the last device in
the chain
