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 pressing 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 barcode on the
cradle with the new digital scanner; or, scan Lock Override (<em_Emphasis><bl_blue>page 9-72) with
the new digital scanner then scan the PAIR barcode 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 unpair barcode
on<em_Emphasis><bl_blue>page 9-74 to ignore the Connection Maintenance Interval and make the
connection immediately available.
To set the Connection Maintenance Interval, scan one of the barcodes below
.
note The Connection Maintenance Interval only applies in locked pairing mode (see
<em_Emphasis><bl_blue>page 9-71).
note The cradle 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
<bl_blue><em_Emphasis>Unpairing barcode prior and reconnect each appropriate digital scanner by
scanning the PAIR barcode on the cradle.
