Clearing cues and cue lists
To clear button function, right click the line representing the button and select clear.
The preferences menu
Preset use Cues/Preset use Background Cues - use this switch to determine if the preset buttons are
used to call up regular cues or background cues. The dialog will automatically switch between
showing assigned cues or background cues.
Clear Cue/BGCue on Preset Off - when enabled the current cue or background cue is cleared when
the preset button is toggled off. Note that the cue will only be cleared if it is identical (same cue/
background cue number) as the one assigned to the preset button - e.g.. if cue #1 is loaded by preset
button 1 it will only clear the cue when toggled off, if the current cue is #1.
Clear Cuelist on Auto off - When enabled, toggling the Auto button off clears the current cue list, but
only if the current cue list is identical to the cue list assigned to the Auto button (see above)
Clear Cuelist on Preset - When enabled the current cue list will be cleared as any of the preset
buttons toggled on. This function will clear any cue list.
RS-232 remote control
The RS-232 remote control option is supported through an external support application, LJ_RS232.
EXE - located in the LightJockey Installation folder.
The RS-232 remote application
For automated purposes, either start the program via the Windows Startup folder, or use
LightJockey's auto-launch facility in the startup options. The program enables remote control various
LightJockey options, such as calling up a cue or call a fade out. Before the application can be used,
RS-232 settings to be used must be configured. Select Setup -> RS 232 settings to configure the
RS-232 parameters. Select COM Port from 1 through 4 and one of the possible Baud-Rates. The RS-
232 data format is fixed at 8 data bytes, 1 stop byte and no parity.
RS-232 Protocol
The RS-232 protocol is based on a 3 byte binary protocol.
The format for all commands are identical: [Command] [Data1 (MSB)] [Data2 (LSB)]
All 3 bytes must be sent to LightJockey within 0.2 seconds, otherwise an incomplete command times
out.
All bytes with a value of 128 or above are treated as a [command] byte. Consequently all data bytes
must have a value of 127 or lower.
When the both the data bytes are used to send a value the value must be split into an MSB and an
LSB pair.
Examples:
To load cue number 130: Send [129] [1] [2] - 129 is the Load Cue command, and 1*128+2 selects
cue number 130.
To load cue list number 2 Send [128] [0] [2] - 128 is the load cue list command, and 0*128+2 selects
cue list number 2.
