Motorola DS3478 User Manual

4 - 10 Symbol DS3478 Product Reference Guide

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 digital scanner for a period of time defined by the Connection Maintenance 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 during this interval. Connection Maintenance Interval options are:

15 minutes

30 minutes

One hour

Two hours

Four hours

Eight hours

24 hours

Indefinitely.

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

 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.
