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.
The conversion table below is for use with the command and response table.
