 Error Codes
If an exception code other than 00 hex (normal operation) is returned in the response from the Reader/
Writer, you can use a GET COMMUNICATIONS ERROR LOG query to get details on the nature of the
error.
The following tables list the error codes that indicate the response results from the Reader/Writer. If an
error response is returned (i.e., an error code other than 0000 hex), a record is recorded in the
communications error log in the Reader/Writer. Records are not recorded for errors for which
responses are not returned to the host device. Reader/Writer operating errors and system errors are
recorded in the system error log in the Reader/Writer.
