INSTRUCTIONS FOR A RELIABLE DMX CONNECTION
Use shielded twisted-pair cable designed for RS-485 devices: standard microphone cable cannot trans-
mit control data reliably over long runs. 24 AWG cable is suitable for runs up to 300 meters (1000 ft).
Heavier gauge cable and/or an amplifier is recommended for longer runs.
To split the data link into branches, use splitter-amplifiers in the connection line.
Do not overload the link. Up to 20 devices may be connected on a serial link and 11 units througth
RDM or DATAMASTER.
NOTE: To connect the unit to your DMX network, it is necessary to use the adapters XLR 5 pin-
IP67 signal connector, supplied with this product.
CONNECTION DAISY CHAIN OF THE DMX LINE
Connect the DMX data output from the DMX source to the product DMX input (male connector).
Run the data link from the product DMX output (female connector) connector to the DMX input of the
next fixture.
Terminate the data link by connecting a 120 Ohm signal termination.
The termination is prepared by 120Ω 1/4 W resistor between pins 2 and 3 of the male DMX connector.
Install a DMX termination plug on the last fixture on the link. If a splitter is used, terminate each branch
of the link.
NOTE: when not using the DMX input or DMX output connectors, you must seal the cable ends
with the supplied caps.
