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. Error
response codes and their descriptions are as follows:
E01 – Invalid input channel number (out of range)
E06 – Invalid input selection during auto-input switching
E10 – Invalid command
E13 – Invalid parameter (out of range)
Using the Command/response Table
The command/response table on the following pages lists valid ASCII and hexadecimal
command codes, the responses from the switcher to the host, and a description of the
command function or the results of executing the command.
The ASCII to HEX conversion table below is for use with the command/response table.
