Video SEND_COMMANDs (Transmitters), continued
?VIDIN_STATUS
Requests the status of the video
input on the Transmitter.
Important:
In the case of the
Multi-Format TX, Wallplate TX,
or Decor Wallplate TX this will
only specify the status of the
currently routed input port.
Important:
Send to Port 7 for digital video or to Port 8 for analog video.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_STATUS'"
Variable:
status = NO SIGNAL, UNKNOWN SIGNAL, VALID SIGNAL
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_STATUS'"
Returns a COMMAND of the form:
VIDIN_STATUS-<status>
?VIDIN_FORMAT
Requests the video format on the
Transmitter.
Note:
All DXLink Transmitters
except the HDMI TX support
component, S-Video,
composite, and VGA signals.
Note:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_FORMAT'"
Variable:
format (port 8) = COMPONENT, S-VIDEO, COMPOSITE, VGA
format (port 7) = HDMI, DVI
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_FORMAT'"
Returns a COMMAND of the form:
VIDIN_FORMAT-<format>
VIDIN_FORMAT
Sets the video format on the
Transmitter (prior to sending,
VIDIN_AUTO_SELECT must be
set to DISABLE).
Note:
All DXLink Transmitters
except the HDMI TX support
component, S-Video,
composite, and VGA signals
Note:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'VIDIN_FORMAT-<format>'"
Variable:
format (port 8) = COMPONENT, S-VIDEO, COMPOSITE, VGA
format (port 7) = HDMI, DVI
Example:
SEND_COMMAND dvMFTX,"'VIDIN_FORMAT-COMPONENT'"
?VIDIN_RES_AUTO
Requests the setting for the Auto
mode on the Transmitter (Enable
or Disable).
Note:

Returns a COMMAND of the form:
VIDIN_RES_AUTO-<ENABLE|DISABLE>
VIDIN_RES_AUTO
Enables or disables the Auto
mode (for automatically
determining the resolution) on
the Transmitter.
Note:

Example:
SEND_COMMAND dvMFTX,"'VIDIN_RES_AUTO-ENABLE'"
?VIDIN_RES_REF
Requests the resolution and
refresh rate of the video through
the Transmitter.
Note:
Send to Port 7 or Port 8.
Syntax:
SEND_COMMAND <DEV>,"'?VIDIN_RES_REF'"
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'.
• rate = An integer value representing the refresh rate.
Example:
SEND_COMMAND dvMFTX,"'?VIDIN_RES_REF'"
Returns a COMMAND of the form:
VIDIN_RES_REF-<horizontal>x<vertical>,<rate>
