Rockwell Automation 2755-DM9, -DM9E High Speed Decoder - Manual (Page 92)

Chapter 6
Communicationg With a Host
6–10
Example #3 - If a No-Read occurs, the decoder would transmit the following:
#183Data From Scanner 1B3=No-Read==000015CRLF
Where 000015 is the package count.
Your host device can also transmit commands to the decoder. Using these
commands you can request data and/or change the operating configuration of
the decoder. Depending upon the type of communication interface used to
communicate with the decoder, refer to the following chapter:
•
If you are using the RS-232 or RS-422 interface, refer to Chapter 7.
•
If you are using the RS-485 interface, refer to Chapter 8.
Note: Chapter 7 and Chapter 8 describe the format of both a host command
and the decoder’s response to a command.
