Encoder Error Responses

When the encoder receives a valid SIS command, it executes the command and sends a
response to the host device. If the encoder is unable to execute the command because the
command is invalid or it contains invalid parameters, the encoder returns an error response
to the host. The error response codes are:
E10 — Invalid command
E12 — Invalid port number
E13 — Invalid parameter
E14 — Invalid for this port configuration
E17 — Invalid command for signal type
E22 — Busy
E24 — Privilege violation
E25 — Device not present
E28 — Bad file name or file not found
The command operation is aborted with no other indication.
