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.
