Ethernet/Serial/USB Control
The Light Cue Pro may be controlled using Ethernet using UDP on
port 2639, USB, or serial RS-232 messages via the rear DB-9
Control Connector or the DB-37 Control Connector. The data
format is 9600,N,8,1: 9600 baud, no parity, 8 bits/byte, with one
stop bit. The protocol is ASCII-based, and many commands are
identical to Pioneer Disc protocol. Upper or lower case characters
can be used interchangeably.
The most commonly used serial commands are:
“Jam-sync” means that
the DMX data will jump
ahead, backward, or
pause to maintain
synchronization to
incoming SMPTE
timecode.
