“Request Breakaway Setting”

Request: 0x0b <setup#> <value> <machine>

Response: 0x4b <setup#> <response> <machine>

Action: Request breakaway switching setting

The “Request Breakaway Settings” command is used to poll either the current breakaway configuration of the switcher, or a setup breakaway configuration. Specifying a value parameter of 0 requests current audio breakaway setting, and a value parameter of 1 requests the “follow” setting. Breakaway switching / follow is stored in setups. Example:

“Error Response”

Request: Not Valid

Response: 0x50 0x00 <error> <machine>

Action: Response sent to client from switcher

The “Error Response” is used by the switcher to send error messages to the client. An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the instruction is out of range (e.g., trying to save to a setup greater than the highest one, or trying to switch an input or output greater than the highest one defined). Reception of this code by the switcher is not valid. The error value can be any of the following values:

Error:

0 – Error

1 – Invalid Instruction

2 – Out of Range

3 – Machine Busy

Example:
