Zebra DS6878 Product Reference Guide

4 - 26 DS6878 Product Reference Guide
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 4-23) 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 4-24 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 4-23).
NOTE When the CR0078-S cradle supports the maximum three digital scanners and the CR0078-P supports the
maximum seven 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.
