BT SECURITY FEATURES
On the BT system, it is possible to set a (configurable) PIN code to authenticate/connect BT 
devices, and encrypt the data.
The BT PIN code can be enabled and configured by reading the bar codes
 in the following sec-
tions.
If you are using a BT scanner directly connected to a host through a BT dongle, verify that 
the scanner and the BT driver used by the dongle share the same PIN code and the same 
security level. Otherwise the connection cannot be established.
Follow these steps to set the PIN code for a scanner:
1. Enable BT Security Mode  by scanning the “Enable” ba
r code below.
2. Select a PIN code length of either 4 or 16 characters by scanning the appropriate bar code 
in
 "Select PIN Code Length" on pa
ge 224.
3. Scan the relevant bar code from "Set PIN Code" on page 22
4, then scan the desired alpha-
numeric characters from the keypad in Appendix D Keypad to set the PIN code.
See page 264 in “References” for more detailed information and examples for this feature.

This feature enables/disables authentication and encryption of the BT link. Use the feature "BT

Changing the security mode setting will unlink the devices. If the Automatic Configuration 
Update is set to the default “Enabled” setting, the devices must only be relinked. If the 
Automatic Configuration Update is set to “Disabled,” the Security Mode setting must also 
be updated in the Base Station using Aladdin. After the Base Station has been updated, the 
devices must be relinked.
