First switch all Audio and video outputs from input 1,
Then switch video input 3 to output 4, video input 2 to output
2, video input and disconnect video output 2.
Then switch audio input 3 to output 2,
Then disconnect audio output 1.
Then get status of all links (assume this is 4x4 matrix).
Commands processing start after entering
CR
, response will sent
for each command after processing it.
