Dmx Connection; A) Connection Of A Dmx Controller With Cable - Renkforce GM-313 Bedienungsanleitung

8. DMX connection

Use of XLR microphone cables may cause interferences in the DMX signal transmission. In this case,
please use special DMX high-frequency cables.
Never use any damaged DMX lines. Do not use any Y branches. The devices must be connected in series
directly to each other.

a) Connection of a DMX controller with cable

Only connect the device to a DMX controller with a DMX-512 protocol.
• Connect the connection DMX IN with the output of the DMX controller.
• The controller must have 4 or 7 free control channels (depending on DMX operating mode set at the effect light).
• Connect DMX OUT with the DMX input of the subsequent device.
• Proceed accordingly with all other devices of the DMX chain.
• If the effect light 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 OUT 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 effect light; this may result in interference in
signal transmission caused by ground loops.
