Error Responses
If the switcher is unable to execute a command it receives because the command is invalid
or contains invalid parameters, the SW USB returns an error response to the host. Error
response codes and their descriptions are:
E01 – Invalid input channel number (out of range)
E10 – Invalid command
E13 – Invalid value (out of range)
Using the Command and Response Table
The Command and Response Table on the next page lists valid ASCII command codes,
the responses of the switcher to the host, and descriptions of the command functions or the
results of executing the commands. The ASCII to Hex Conversion Table below is for use with
the Command and Response Table.
