Connection Maintenance Interval
When a digital scanner disconnects from a cradle due to a Link Supervision Timeout, the digital scanner
immediately attempts to reconnect to the cradle for 30 seconds. If the auto-reconnect process fails, it can be
restarted by pulling the digital scanner trigger.
To guarantee that a disconnected digital scanner can reconnect when it comes back in range, the cradle reserves
the connection for that digital scanner for a period of time defined by the Connection Maintenance Interval. If the
cradle is supporting the maximum three digital scanners and one digital scanner disconnects, a fourth digital
scanner cannot pair to the cradle during this interval. To connect another digital scanner: either wait until the
connection maintenance interval expires then scan the PAIR bar code on the cradle with the new digital scanner;
or, scan Lock Override (page 4-20) with the new digital scanner then scan the PAIR bar code on the cradle.
Connection Maintenance Interval options are:
• 15 minutes
• 30 minutes
• One hour
• Two hours
• Four hours
• Eight hours
• 24 hours
• Indefinitely.
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 unpair bar code on page 4-21 to ignore the
Connection Maintenance Interval and make the connection immediately available.
NOTE The Connection Maintenance Interval only applies in locked pairing mode (see page 4-20).
NOTE When the cradle supports the maximum three digital scanners, it stores the remote pairing address of
each digital scanner in memory regardless of the digital scanner condition (e.g., discharged battery).
When you want to change the digital scanners paired to the cradle, unpair each digital scanner currently
connected to the cradle by scanning the Unpairing bar code prior and reconnect each appropriate digital
scanner by scanning the PAIR bar code on the cradle.
