<ENABLE|DISABLE>'"
Variable:
value = ENABLE | DISABLE
Example:
SEND_COMMAND dvTX,"'VIDIN_AUTO_SELECT-ENABLE'"
?INPUT-VIDEO
Requests the video input being
used on the TX (output is
always 6): either the digital
video input (Port 7) or the
analog video input (Port 8).
If neither port is connected,
the reply is 0.
Note: This command applies to
the Multi-Format TX and
Wallplate TX only.

Wallplate TX only.
Important: This command must be sent to Port 1.
Syntax:
SEND_COMMAND <DEV>,"'VI<input>O<output>'"
Variables:
input = 7 for digital video; 8 for analog video
output = 6
Example:
SEND_COMMAND dvTX,"'VI8O6'"
?VIDIN_STATUS
Requests the status of the
video input on the Transmitter.
Important: This only specifies
