External Control Commands
Pause (PA)
Command:
Pauses the current file position and blacks out the picture.
Format:
PA<CR>
Response:
R<CR>
Explanation:
The PA command will pause playback, Scan Reverse or Scan
Forward. While having no visible effect on screen, it should also
transition from Stop to Pause holding on frame 1 of the first file of
the playlist. This is simply for compatibility with LDV devices
which can use PA as a means of spinning up the disc without
actually beginning playback. By transitioning from Stop to Pause
the Firefly will
give the control system the expected response if a status request is
made later. In all cases, PA results in video being blacked out until
another command is received. The Blackout will only remain in
effect for as long as the unit is in Pause mode. Any command
which transitions out of Pause mode will also unmute the video.
Examples:
PA<CR>
Pauses the Firefly and blacks out the video outputs.
0@PA<CR>
Pauses the Firefly and blacks out the video output.
