Pairing Bar Code Format
When the device is configured as an SPP Master, you must create a pairing bar code for the remote Bluetooth
device to which the device can connect. You must know the Bluetooth address of the remote device. Pairing bar
codes are Code 128 bar codes and are formatted as follows:
device to which the device can connect. You must know the Bluetooth address of the remote device. Pairing bar
codes are Code 128 bar codes and are formatted as follows:
<Fnc 3>Bxxxxxxxxxxxx
where:
•
B (or LNKB) is the prefix
•
xxxxxxxxxxxx represents the 12-character Bluetooth address.
Pairing Bar Code Example
If the remote device to which the device can connect has a Bluetooth address of 11:22:33:44:55:66, then the
pairing bar code is:

Connection Maintenance Interval
When a device disconnects from a cradle due to a Link Supervision Timeout, the device immediately attempts to
reconnect to the cradle for 30 seconds. If the auto-reconnect process fails, it can be restarted by pulling the device
trigger.
reconnect to the cradle for 30 seconds. If the auto-reconnect process fails, it can be restarted by pulling the device
trigger.
To guarantee that a disconnected device can reconnect when it comes back in range, the cradle reserves the
connection for that device for a period of time defined by the Connection Maintenance Interval. If the cradle is
supporting the maximum three devices and one device disconnects, a fourth device cannot pair to the cradle
during this interval. To connect another device, either wait until the connection maintenance interval expires then
scan the PAIR bar code on the cradle with the new device; or scan Lock Override (

supporting the maximum three devices and one device disconnects, a fourth device cannot pair to the cradle
during this interval. To connect another device, either wait until the connection maintenance interval expires then

Connection Maintenance Interval options are:
•
15 minutes
•
30 minutes
•
One hour
•
Two hours
•
Four hours
•
Eight hours
•
24 hours
•
Indefinitely.
Paring Bar Code Content:

NOTE
The Connection Maintenance Interval only applies in locked pairing mode (see
NOTE
When the cradle supports the maximum three devices, it stores the remote pairing address of each device
in memory regardless of the device condition (e.g., discharged battery). When you want to change the
devices paired to the cradle, unpair each device currently connected to the cradle by scanning the
in memory regardless of the device condition (e.g., discharged battery). When you want to change the
devices paired to the cradle, unpair each device currently connected to the cradle by scanning the
bar code prior and reconnect each appropriate device by scanning the PAIR bar code on the
cradle.
