Rs232 / Ir Control - Adcom GDV-850 Owner's Manual

[48] Menu Button
The menu button will always display
the menu for a disc when pressed. If
pressed when in a playback mode, the
location is marked and play may be
resumed by using the resume button
on the remote, as described below.
[49] Navigation Buttons &
Select Button
This group of buttons is used to navi-
gate the OSD for the menus of the DVD
player itself and the menus for discs
during playback. This group of buttons
is comprised of four direction buttons
and a select button in the center.
[50] Subtitle Button
The subtitle button will display subti-
tles in languages available on the disc.
Continue to press this button to cycle
to the next language or to turn sub-
titles off. If a preference has been set
to display subtitles in the DVD player's
setup menu, making this selection
during playback will only affect that
single playback of the DVD-disc.
[51] Zoom Button
Use the zoom button to magnify the
video track. Press the zoom button to
first set the magnification to a level of
X1.5, pressing this button again will set
the level to X2.0. Use the navigation
buttons to move to different areas of
your magnified image. The movie will
continue to play while the zoom fea-
ture is active. To exit the zoom mode
press the zoom button a third time.
[52] Angle Button
An angle is a scene recorded from dif-
ferent viewpoints. Each angle is equal
in time length, and an angle block may
contain up to nine (9) angles. Pressing
this button will cycle through any
available angles. If none are available
a white hand will be displayed.
[53] Resume Button
The resume button functions much
like the play button and will resume
playback when using other functions
of the DVD player, such as slow/step
or while in the menu.
[54] RGB Video Output Button
Pressing this button turns the optional
RGB video output on. Note: This fea-
ture may be disabled in some regions
due to copy protection requirments.
[55] Compnt (Component)
Video Output
Pressing this button turns the compo-
nent video output on. Note: This fea-
ture may be disabled in some regions
due to copy protection requirments.
[56] Digital Audio Out Off
Pressing this button turns the digital
audio output off. When turned off
the GDV-850 will output the highest
resolution signal via the analog out-
put jacks. Note: This feature may be
disabled in some regions due to copy
protection requirments.
[57] Digital Audio Out On
Pressing this button turns the digital
audio output on. The bitstream select-
ed on disc will be sent to preamp. Due
to copy protection requirments, when
playing a DVD-Audio with digital audio
out on, DVD-Audio will be truncated to
16bit/48k operation.

2.3 RS232 / IR Control

The Adcom GDV-850 can be controlled
via its serial RS-232 port. The serial port
can be connected to a PC or 'dumb ter-
minal' via a straight-through standard
9-pin serial port cable (MALE on one
end and FEMALE on the other end).
When using a PC, a terminal emulator pro-
gram, such as ProComm or the Windows
"Terminal" program can be used.
The communications
should be set as follows: 9600 baud,
8 data bits, no parity, 1 stop bit and
Hardware Flow Control
Some of the commands can only be sent
to the Video Switch when it has been
'unlocked'. This protects it against
inadvertent re-programming of its
serial number, and its default settings.
NOTE: all commands are CAPITAL let-
ters (ASCvII characters)...lower case
letters, or unrecognized commands
are ignored and a '?' may be returned.
Data bytes associated with a command
can be upper or lower case letters and
numbers as appropriate.
Commands can only be entered after
the ">" prompt character is displayed.
The exception to this rule is that the
GDV-850 does not echo the command
prompt when first plugged in. After
the first command is received, prompts
are then automatically generated.
When a command has been received,
the command letter is echoed, fol-
lowed by a CR/LF, then ">" as a
prompt character.
If the command is one that returns
data (e.g. "S" – Status), then the data
is returned, followed by the echoed
command letter, and a CR/LF, then
">" as a prompt character.
Command echoing can be turned on and
off by issuing the "E" command (see
below). The GDV-850 echoes commands
by default on line cord power-up.
