Dmx Connection; Connection Of A Dmx Controller - MC Crypt GLPS320-RGB Bedienungsanleitung

10. 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. The controller must have
17 free control channels.
• Connect the port DMX INPUT (4) with the output of the DMX controller.
• Connect DMX OUTPUT (3) with the DMX input of the subsequent device.
• Proceed accordingly with all other devices of the DMX chain.
• If the laser is the last or the only device in the DMX chain, insert an XLR plug with a 120 ohm/0.25 W terminating
resistor into the DMX OUTPUT (3) socket (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 device; this may result in interference in signal
transmission caused by ground loops.
