Error Messages
When the switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the switcher is unable to execute the command because the command is invalid or it contains invalid parameters, the switcher returns an error response to the host. The error response codes are:
E01 | – | Invalid input channel number (out of range) |
E06 | – | Invalid input channel change (auto switch is active) |
E10 | – | Invalid command |
E13 | – | Invalid parameter |
