Dmx Connection; A) Connection Of A Dmx Controller - Renkforce DL-LED107S Operating Instructions Manual

7. 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 connection DMX IN with the output of the DMX controller.
• The controller must have three or six 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 inter-
ference in signal transmission caused by ground loops.
