Auxiliary Reader Control — Command Group 8
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 7-23.

830 Disable Automatic Periodic RF Status Report (Factory
Default)

status report.
Reader response:
Done
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 min-
utes.
