mand acknowledgment. The LRP830 sends the second when the first
EAS-enabled tag enters the field, A third response is sent when field is clear
of EAS-enabled tags. Family ID is set to 0 so that any EAS-enabled tag will
trigger responses.
When an EAS-enabled tag enters the antennas’ field, the LRP830 responds
with an EAS tag-in-field response.
When all EAS-enabled tags have left the field, the LRP830 will send the fol
-
lowing response.
