Status change messages
The switcher-initiated status change messages are a result of front panel operations (actual
or software-simulated). The status change messages are the same as switcher responses
to certain commands. See the last column of the command and response command tables
(see the
MPS Switcher Error Responses
When the MPS switcher receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the switcher is unable
to perform the command because the command is invalid or contains invalid parameters, it
returns an error response to the host. The error response codes are:
E01 ] — Invalid input channel number (too large)
E06 ] — Invalid switch command (due to auto-input switch enabled)
E10 ] — Invalid command
E13 ] — Invalid parameter (out of range)
E14 ] — Not valid for this configuration
E17 ] — Invalid command for signal type
E22 ] — Busy
