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 32 devices may be connected on a serial link.
CONNECTION DAISY CHAIN
Connect the DMX data output from the DMX source to the product DMX input (male connector XLR)
socket.
Run the data link from the product XLR output (female connector XLR) socket to the DMX input of the
next fixture.
Terminate the data link by connecting a 120 Ohm signal termination. If a splitter is used, terminate
each branch of the link.
Install a DMX termination plug on the last fixture on the link.
CONNECTION OF THE DMX LINE
DMX connection employs standard XLR connectors. Use shielded pair-twisted cables with 120Ω im-
pedance and low capacity.
The following diagram shows the connection mode:
