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)
E10
]
— Invalid command
E13
]
— Invalid value (out of range)
