32 Serial Control
Active Mode Request
Description: This command causes the Digital Video Machine 2 to report its Active
Operating Mode.
Command bytes: [<ID>@]?P<CR>
Message Response: P0n<CR>
where n is 1 (Stopped), 3(Searched), 4 (Playing), 5 (Stilled) or 6 (Paused)
Chapter Request
Description: This command causes the Digital Video Machine 2 to report its Active Chapter.
Command bytes: [<ID>@]?C<CR>

Audio Sample Rate Select
Description: This command causes the Digital Video Machine 2 to change the sample rate at
which it plays audio.
Command bytes: [<ID>@]nAR<CR>
where n is 0 (Auto Detect), 1 (32KHz), 2 (44.1KHz) or 3 (48KHz)
Message Response: R<CR>
Comments: The DVM2 will automatically decide on a default sample rate at power-up. If
an auto executing file exists that causes video to play at power-up (playlist #0,
video #0, schedule, etc), the first video to play will determine the default sample
rate. Otherwise, the lowest numbered clip on the unit will determine the default
sample rate. This default sample rate will persist for the duration of the power
cycle. If the Sample Rate Select command is used to switch to Auto Detect
mode, each search will take longer while the unit determines the sample rate of
the selected video.
Device ID Set
Description: This command causes the Digital Video Machine 2 to change its Device ID.
This command is useful if you cannot use Ethernet and the Web Page Setup.
Setting Device ID’s should be done one unit at a time. When communicating
with multiple units, do not send this command as a wildcard command, as this
will change every unit’s Device ID.
Command bytes: [<ID>@]nID<CR> or [<ID>@]nnID<CR> or [<ID>@]nnnID<CR>
where n, nn, or nnn is the Device ID in ASCII (‘0’ -‘126’). Do not use ‘127’ as
this is the designated wildcard ID.
