Motorola Symbol LS4278 - Connection Maintenance Interval

Radio Communications 4 - 23
Connection Maintenance Interval
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 bar code on the cradle with the new scanner; or, scan Lock Override (page 4-20) with the new
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 scanners, it 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 bar code prior and reconnect each appropriate scanner by scanning the PAIR bar
code on the cradle.
