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
E13 - Invalid parameter
E14 - Invalid command for this configuration
