(Connection via) VIATOR Bluetooth modem
The VIATOR Bluetooth modem is a point-to-point interface for temporary connection to HART-
enabled field devices for configuration purposes. It is approved for hazardous areas and operates for
approx. 20 hours when powered by replaceable batteries. Our Field Xpert and the modem
communicate via Bluetooth, with the modem connected via cable to the HART field device.
The VIATOR Bluetooth modem incorporates a Class 1 Bluetooth radio with a range of up to
100 meters. The Field Xpert is equipped with a Class 2 Bluetooth adapter, which limits the range
to 10 meters. The range can be reduced by interference from other nearby devices transmitting in
the 2.4 Ghz ISM band. Sources of interference include cordless telephones, wireless networking
devices and also microwave ovens. In certain circumstances, reception interference may cause a
Bluetooth connection to be terminated completely, resulting in a redial into the HART network.
