The product has a DMX 512 input fitted with standard 5-pin XLR connectors. Screened cables in
compliance with EIA RS-485 specifications and the following characteristics must be used for connections:
- 2 conductors plus screen
- 120 Ohm impedance
- low capacitance
- max. transmission rate 250kBaud.
Cable connections:
see illustration, taking care with the screen, which must be connected to
Pin 1
DMX-512 connection with DMX terminator
For installations where the DMX cable has to run a long distance or is in an electrically noisy environment,
such as in a discotheque, it is recommended to use a DMX terminator. This helps in preventing corruption
of the digital control signal by electrical noise. The DMX terminator is simply an XLR plug with a 120 Ω
resistor connected between pins 2 and 3,which is then plugged into the output XLR socket of the last
fixture in the chain. Please see illustrations below.
