After Reset, power-up or after changing the batteries, the Nordic ID RF651 will try to connect to the last device, in which
it was connected before switching off the power. If this device is not found, the device list (“Friendly Name”) will appear
on the screen and the user can select another device to connect.
Connection will be maintained until the Nordic ID RF651 goes to sleep, which will happen if no keys are pressed within
90 seconds, or alternatively the RF651 will maintain the connection also during the sleep (only display will be switched
to sleep mode). The user may select the type of operation by a special keyboard combination command (<SHIFT> +
<1> will toggle between the two different operation modes). When the user wakes the device up by pressing any key, the
Bluetooth connection will be established again if it was disconnected during entry into sleep mode.

Security
Bluetooth technology offers a high level of data transfer security. It is necessary that no external party without proper
authentication is able to access the network with a Bluetooth capable device.
Security implementation on the Nordic ID RF651 system is based on three factors:
• PIN code (0000-9999). The PIN code defines the Nordic ID RF651 network. The PIN code must be the same in the
Bluetooth Dongle installed into the Host Computer or on the Bluetooth Access Server(s) and in the Hand Terminal
before they can communicate with each other.
• Bluetooth data link encryption
• Authorizing scheme at the application side
This may include a password and user name input screen defined by the Host Application and displayed as the first
screen visible to the user trying to connect to the Host Application. Thus even with an authorized Bluetooth Hand
Terminal the user will have to identify him/herself. Furthermore the CommID of the Hand Terminal may also be used to
distinguish between an allowed and rejected Hand Terminal.

The Nordic ID RF651 Main Features
• Fast transactions with the Host Application over a Bluetooth connection (approximately 200 ms).
• Connects automatically to the last connected device after reset.
• Class 1 RF output power (100 meters).
The Nordic ID RF651 Hand Terminal is like a “Remote control” of the Host Application. No programming
is required in the Hand Terminal and the displayed screens (text) are defined by the Host Application. The
Host Application defines the user interface elements of the Hand Terminal screens.
