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
E12 — Invalid output number
E13 — Invalid range
E22 — Busy
Timeout
Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The
command operation is aborted with no other indication.
