Responses
The Series 2000 Controller returns a variety of responses that can be bro-

Success
All successful responses start with an A. If there is data returned, it will
follow the A and have a checksum after it. All responses end with a car-
riage return.
Examples:

All failure responses start with a N followed by a two hex digit failure
code and a carriage return.
