9. DMX Connection
You can operate a maximum of 32 devices in a DMX chain without overloading the controller.
The maximum total length of the DMX chain should not exceed 500 m.
Use of XLR microphone cables may cause interferences in the DMX signal transmission. In this
case, please use special DMX high-frequency cables.
a) Connection of a DMX Controller
Only connect the device to a DMX controller with a DMX-512 protocol.
• Connect the DMX INPUT (3) DMX input to the DMX controller output.
• Use a screened XLR cable for this. The controller must have up to 48 free control channels depending on DMX
operating mode.
• Connect the DMX OUTPUT (4) DMX output with the DMX input of the next device in sequence. If the effect light is
the last or only device in the DMX chain, insert a plug with a 120 Ohm/0.25 W terminator here (between Pin2 and
Pin3).
Pin assignment of the DMX connection: Pin1 = earth / Pin2 = (-) / Pin3 = (+).
Never connect the earth pin GND to the casing earth of the effect light; this may result in interference in
signal transmission caused by ground loops.
