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. Field Xpert and the modem communicate
with each other 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 maximum 10 meters, see also Chapter 4.1.7.
Notice!
• The modem is certified for use in hazardous areas, Zone 1. Once a modem has been used in a
non-Ex installation, it should never be used in an Ex installation, as there is a danger that the
protective circuits have been inadvertently overloaded and no longer function correctly.
