Dmx Connection; Connection Of A Dmx Controller - MC Crypt DL-1114S Bedienungsanleitung

8. 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 IN DMX input to the DMX controller output.
• Use a screened XLR cable for this. The controller must have 2 free control channels.
• Connect the DMX OUT output to the DMX IN input of the subsequent device. 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.
