Communication Protocols

“Switch Audio”: Switch Audio Crosspoint”

Request: 0x02 <input> <output> <machine>

Response: 0x42 <input> <output><machine>

Action: Set output to input

The “Switch Audio” command is used to request that a connection be made. Input and output are specified in hexadecimal notation. If 0 is specified for output, all outputs will be switched to the specified input. If 0 is specified for input, the specified output will be disconnected (Audio Mute). Bi-Directional command example:

	Command	Meaning
Command To Switcher	0x02 0x85 0x88 0x81	Connect audio input 5 to output 8
Response From Switcher	0x42 0x85 0x88 0x81	Audio input 5 connected to output 8

“Request Video Output Status”

Request: 0x05 <setup#> <output> <machine>

Response: 0x45 <setup#> <input><machine>

Action: Request status of Output

The “Request Video Output Status” command is used to request the current input connected to a specified output. This allows clients to poll the current status of the switcher. Bi-Directional command example:

	Command	Meaning
Command To Switcher	0x05 0x80 0x88 0x81	Request video input on output 8
Response From Switcher	0x45 0x80 0x85 0x81	Video input 5 is connected

“Request Audio Output Status”

Request: 0x06 <setup#> <output> <machine>

Response: 0x46 <setup#> <input> <machine>

Action: Request status of Output

The “Request Audio Output Status” command is used to request the current input connected to a specified output. This allows clients to poll the current status of the switcher. Bi-Directional command example:

	Command	Meaning
Command To Switcher	0x06 0x80 0x88 0x81	Request video input on output 8
Response From Switcher	0x46 0x80 0x85 0x81	Video input 5 is connected
