will compare the values for those bytes. If the corresponding characters in the Data
matches the data in the tag for those locations, the tag will respond. If not, the tag will
not respond, and thus, will not be read or reported by the reader.

Command Group 8 – Auxiliary Reader Control
Group 8 commands provide control of reader functions, such as the sense input lines.
82N Select Input Status Change Report Option
Command #82N selects the input lines to be monitored to report any change in input status. The enabled
input lines are monitored for any changes in the logic states. If a change is detected, the reader generates
an input status change message and treats it as a tag ID. If the auxiliary information option is enabled, the
input status field displays the current input values. The value for N specifies the report options as shown
in Table 41 .

831 Enable Automatic Periodic RF Status Report
Command
#831
enables the automatic periodic RF status report. This function sends out a periodic RF
status report if no other message (a tag read) is sent from the reader for a period of time. This message
is the same message that would be sent in response to the
#527 Display RF Status
command.
Enabling this function is helpful in some sites where there may not be much tag activity, and the user wants
an automatic way to ensure the communication channel with the reader is still intact. With this function
enabled, the host system will get a message from the reader at least every three minutes.
