Instruction Manual - Incite Digital Video Presentation Systems
Sets the resolution and refresh rate of the video input port addressed by D:P:S. Invalid combina-
tions are ignored by the SWITCHER.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_RES_REF-<horizontal>x<vertical>,<refresh-rate>'"
Variables:
horizontal = An integer value representing the horizontal.
vertical = An integer value representing the vertical. May have an additional qualifier such as 'i' or 'p'.
refresh-rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND VIDEO_INPUT_1,"'VIDIN_RES_REF-1440x480i,59'"
For a list of supported resolutions, see the Appendix A - Input Resolutions on page 135.
Requests the video input status of the video input port addressed by the D:P:S
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_STATUS'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_STATUS'"
Returns a COMMAND string of the form:
VIDIN_STATUS-<status string>
Requests the input Vertical shifting of the VGA video port addressed by the D:P:S. This command is
only valid for inputs whose format is set to VGA.
Syntax:
SEND_COMMAND <DEV>, "'?VIDIN_VSHIFT'"
Example:
SEND_COMMAND VIDEO_INPUT_1,"'?VIDIN_VSHIFT'"
Returns a COMMAND string of the form:
VIDIN_VSHIFT-<value>
Sets the vertical shift of the video port addressed by the D:P:S to <value>. This command is only
valid for inputs whose format is set to VGA.
Syntax:
SEND_COMMAND <DEV>, "'VIDIN_VSHIFT-<value>'"
Variables:
value = -10..10
Example:
SEND_COMMAND "'VIDIN_VSHIFT-2'"
Sets the vertical shifting of RGB video input port (#1 based on D:P:S) to 2 (shift upward).
SEND_COMMAND "'VIDIN_VSHIFT--3'"
Sets the vertical shifting of RGB video input port (#1 based on D:P:S) to -3 (shift downward).
Requests the aspect ratio of the video output port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDOUT_ASPECT_RATIO'"
Example:
SEND_COMMAND VIDEO_OUTPUT_1,"'?VIDOUT_ASPECT_RATIO'"
Returns a COMMAND string of the form:
VIDOUT_ASPECT_RATIO-<ratio>
See the VIDOUT_ASPECT_RATIO command for the list of aspect ratios.
Sets the aspect ratio of the video output port addressed by the D:P:S. Note that the <ratio> value is
case sensitive.
Syntax:
SEND_COMMAND <DEV>,"'VIDOUT_ASPECT_RATIO-<ratio>'"
Variables:
ratio = MAINTAIN, STRETCH, ZOOM, ANAMORPHIC
Example:
SEND_COMMAND VIDEO_OUTPUT_1,"'VIDOUT_ASPECT_RATIO-ZOOM'"
Requests the image setting of the video blanking feature on the video port addressed by the D:P:S.
Syntax:
SEND_COMMAND <DEV>, "'?VIDOUT_BLANK'"
Example:
SEND_COMMAND VIDEO_OUTPUT_1,"'?VIDOUT_BLANK'"
Returns a COMMAND string of the form:
VIDOUT_BLANK-<image>
See the VIDOUT_BLANK command for the list of images.
status string = NO SIGNAL, UNKNOWN SIGNAL, or VALID SIGNAL.
