Connection Maintenance Interval
The Connection Maintenance Interval only applies in locked pairing mode.
When a scanner disconnects from a cradle due to a Link Supervision Timeout, the scanner
immediately attempts to reconnect to the cradle for 30 seconds. If the auto-reconnect process
fails, it can be restarted by pulling the scanner trigger.
To guarantee that a disconnected scanner can reconnect when it comes back in range, the
cradle reserves the connection for that scanner for a period of time defined by the Connection
Maintenance Interval. If the cradle is supporting the maximum three scanners and one
scanner disconnects, a fourth scanner cannot pair to the cradle during this interval. To connect
another scanner: either wait until the connection maintenance interval expires then scan the
PAIR symbol on the cradle with the new scanner; or, scan Lock Override with the new
scanner then scan the PAIR symbol on the cradle.
The cradle stores the remote pairing address of each scanner in memory regardless of the
scanner condition (e.g., discharged battery). When you want to change the scanners paired
to the cradle, unpair each scanner currently connected to the cradle by scanning the
Unpairing symbol prior and reconnect each appropriate scanner by scanning the PAIR
symbol on the cradle.
Considerations
The system administrator determines the Connection Maintenance Interval. A shorter interval
allows new users to gain access to abandoned connections more quickly, but causes
problems if users leave the work area for extended periods. A longer interval allows existing
users to leave the work area for longer periods of time, but ties up the system for new users.
To avoid this conflict, users who are going off-shift can scan the Unpairing symbol to ignore
the Connection Maintenance Interval and make the connection immediately available.
