The optional external SERIAL Link interface provides 4x serial RS 232/422 ports via ethernet.
A SERIAL Link port can be used to control the playback control of the timeline via RS232 or RS422. Each port can be connected to a separate sequence to allow multiple input devices to control individual sequences.
Once the serial connection is set up, the following commands are valid:
Sets the sequence state to play
Sets the sequence state to pause
Stops and rewinds the sequence
ID = enter number based on cue ID to jump to that cue directly
(Cue13), sets the timeline now-pointer to the time of cue 13
See further instructions in the Serial Link Device Manual.
