Nonfatal Errors
The NORM/ERR indicator flashes once if an error occurs in communications between the Reader/
Writer and host device or in communications with an RF Tag.
If a nonfatal error occurs, the Reader/Writer will add 80 hex to the function code that was specified by
the host device and set the result in the function code field in the response message. It will also set an
exception code that classifies the error in the exception code field.

Returned Function Code Example for an Error
For details, refer to
Host Communications Specifications.
After the host device detects an error, it can send a GET COMMUNICATIONS ERROR LOG query to
the Reader/Writer to check the error detail information. Refer to the following tables for the error codes
that indicate error detail information.

The NORM/ERROR indicator flash yellow when Communication Diagnosis is enabled and the diagnostic result is
" Warning" . This means NOT occurring error.
Refer to
for communication diagnostic.
If you use multi-Reader/Writer operation, the NORM/ERR indicator on any Reader/Writer that detects an error in
communications with an RF Tag will light red once. The NORM/ERR indicator on any Reader/Writer that normally
completes communications with an RF Tag will light green once. When the Master Reader/Writer returns a response to
the host device, the NORM/ERR indicator will light green or red depending on whether the response shows a normal or
error result.
