Error Responses

When the unit receives a valid SIS command, it executes the command and sends a response
to the host device. If the unit is unable to execute the command because the command is
invalid or it contains invalid parameters, the unit returns an error response to the host. The
error response codes are:
E10 - Invalid command
E11 - Invalid preset number
E13 - Invalid parameter
E14 - Invalid command for this configuration
