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.
