Asynchronous notifications are not available for the Receivers via NetLinx Studio (or Telnet).
Video SEND_COMMANDs (Receivers), continued
Command
Description
?VIDOUT_SCALE
Requests the current Scaling Mode
that the Receiver is set to. The modes
are AUTO (SmartScale
®
), MANUAL,
and BYPASS.
Syntax:
SEND_COMMAND <DEV>,"'?VIDOUT_SCALE'"
Example:
SEND_COMMAND dvRX,"'?VIDOUT_SCALE'"
Returns a COMMAND of the form:
VIDOUT_SCALE-<AUTO/MANUAL/BYPASS>
VIDOUT_SCALE
Sets the Scaling Mode on the
Receiver to AUTO (SmartScale
®
),
MANUAL, or BYPASS.
Syntax:
SEND_COMMAND <DEV>,"'VIDOUT_SCALE-<scaling mode>'"
Valid response:
scaling mode = AUTO, MANUAL, BYPASS
Example:
SEND_COMMAND dvRX,"'VIDOUT_SCALE-MANUAL'"
?VIDOUT_RES_REF
Requests the resolution and refresh
rate of the video through the
Receiver.
NOTE:
If the Scaling Mode is set to
Bypass, the response will be
“BYPASS.”
Syntax:
SEND_COMMAND <DEV>,"'?VIDOUT_RES_REF'"
Valid responses:
• horizontal = An integer value representing the horizontal.
• vertical = An integer value representing the vertical. May have an additional qualifier such as 'i'
or 'p'.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvRX,"'?VIDOUT_RES_REF'"
Returns a COMMAND of the form:
VIDOUT_RES_REF-<horizontal>x<vertical>,<rate>
VIDOUT_RES_REF
Sets the resolution and refresh rate
of the video through the Receiver and
also sets the Scaling Mode to
MANUAL.
IMPORTANT:
The “valid responses”
used must come from the
Resolution Names listed in the table
in the “Supported Output
Resolutions” appendix on
page 110.
NOTE:
The default for Manual Mode
is 1280x1024,60.
Syntax:
SEND_COMMAND <DEV>,"'VIDOUT_RES_REF-<horizontal>x<vertical>,<rate>'"
Valid responses:
• horizontal = An integer value representing the horizontal.
• vertical = An integer value representing the vertical. May have an additional qualifier such as 'p'
or 'i'.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvRX,"'VIDOUT_RES_REF-1920x1080p,60'"
?VIDOUT_RES
Requests the resolution and refresh
rate of the video through the
Receiver.
NOTE:
If the Scaling Mode is set to
Bypass, the response will be
“BYPASS.”
Syntax:
SEND_COMMAND <DEV>,"'?VIDOUT_RES'"
Valid responses:
• horizontal = An integer value representing the horizontal.
• vertical = An integer value representing the vertical. May have an additional qualifier such as
'i' or 'p'.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvRX,"'?VIDOUT_RES'"
Returns a COMMAND of the form:
VIDOUT_RES-<horizontal>x<vertical>,<rate>
?VIDOUT_ASPECT_RATIO
Requests the aspect ratio preference
of the video through the Receiver.
(For explanations of the ratio
options, see page 67.)
Syntax:
SEND_COMMAND <DEV>,"'?VIDOUT_ASPECT_RATIO'"
Valid responses:
ratio = STRETCH (default after FACTORYAV), MAINTAIN, ZOOM, ANAMORPHIC
Example:
SEND_COMMAND dvRX,"'?VIDOUT_ASPECT_RATIO'"
Returns a COMMAND of the form:
VIDOUT_ASPECT_RATIO-<ratio>
