Error Responses

If the switcher is unable to execute a command it receives because the command is invalid
or contains invalid parameters, the switcher returns an error response to the host. The
following error response codes can be sent:

E01

– Invalid input channel number (out of range)

E06

– Invalid input selection during auto-input switching

E10

– Invalid command

E13

– Invalid value (out of range)

Using the Command and Response Table

The

command and response table

, starting on page 22, lists valid ASCII and

hexadecimal command codes, the switcher responses to the host, and a description of the
command function or the results of executing the command.
