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 scanner does not reconnected within 30 seconds, it enters low power mode. Thereafter, when a bar code
is scanned, the scanner attempts to reconnect before transmitting the data.
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 already supporting the maximum four
scanners, and one scanner disconnects, a fifth scanner cannot pair to the cradle during this interval. 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 4-14 to ignore the Connection Maintenance
Interval and make the connection immediately available.
To set the Connection Maintenance Interval, select one of the following bar codes.
*Set Interval to 15 Minutes
Set Interval to 30 Minutes
Set Interval to 60 Minutes
