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 digital scanner does not reconnected within
30 seconds, it enters low power mode. Thereafter, when you scan a bar code, the digital scanner attempts to
reconnect before transmitting the data.
To guarantee that a disconnected digital scanner can reconnect when it comes back in range, the cradle reserves
the connection for that digit al scanner for a period of time defined by the Connection Mai ntenance Interval. If the
cradle already supports the maximum four digital scanners, and one digital scanner disconnects, a fifth digital
scanner cannot pair to the cradle du rin g this interval. Connection Maintenance Interval options are:
•
15 minutes
•
30 minutes
•
One hour
•
Two hour s
•
Four hours
•
Eight hours
•
24 hours
•
Indefinitely.
Considerations
The system administrator de termines the Connection Maintenance Interval. A shorter interval allows new users to
gain access to abandoned connections more quickly, but cause s pr oblems 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 of f-shift can scan the unpair bar code on page 4-13 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 Minut es
Set Interval to 30 Minutes
