30 Serial Control
Select File
Description: This command causes the Digital Video Machine 2 to select the specified A/V
clip or Playlist. Once this command is sent, the next Play command causes the
specified file to play from the beginning. The unit defaults to file #1 at power-
up, unless an autoexec file exists. When receiving this command, the Digital
Video Machine 2 always looks for the file on the currently selected drive.
Command Bytes: [<ID>@]nSE<CR> or [<ID>@]nnSE<CR> or [<ID>@]nnnSE<CR> or
[<ID>@]nnnnSE<CR> or [<ID>@]nnnnnSE<CR>
where n, nn, nnn, nnnn or nnnnn is the file number in ASCII.
or
[<ID>@]”<filename>” SE<CR>
where <filename> is an ASCII file name surrounded by quotation marks.

used in Pioneer Laser Disc protocol. The maximum file number is 99999.
Examples: Select file 215: 215SE<CR>
Select file 4: 4SE<CR> or “ vid00004.mpg”SE<CR>

Play
Description: This command causes the Digital Video Machine 2 to play the file, which was
specified with the “ Select File” command, meaning that often a user will select a
clip and then play it using the SE command above and then the PL command.
This will interrupt the currently playing video and go onto the newly selected
file. If a clip is stilled, this command resumes play. If this command is issued
while a Playlist is being played, the Digital Video Machine 2 will skip to the
next clip in the Playlist and play it. This command sends a response when it is
executed, and another when the playback is complete.
Command bytes: [<ID>@]PL<CR>
Message Response: R<CR>
Completion Response: <CR> (This character is configurable from the Advanced section of the Serial
Port Setup Web Page)
Comments: If the video material ends with a non-black screen, that picture will be displayed
