Video SEND_COMMANDs (Cont.)
?INPUT
Queries for the input
connected to an output.
Normally, if the output port is not connected to any input port then the reply will
indicate this with an input port number of ZERO (0). For the DVX products, at
this time, the output parameter is ignored and assumed to be 1.
Syntax:
SEND_COMMAND <DEV>, "'?INPUT-<sl>,<output>'"
Variables:
sl = AUDIO or VIDEO.
output = The output port number.
Example:
SEND_COMMAND SWITCHER,"'?INPUT-AUDIO,1'"
Think of it as asking: Which audio input port is connected to output port #1?
Returns a COMMAND string of the form:
SWITCH-L<AUDIO|VIDEO>I<input>O<output>.
?OSD
