The Viator® Bluetooth® Interface is a point-to-point HART modem for temporary connection to HART field devices. The modem is operated by replaceable AAA batteries and can operate for approximately 20 hours. It attaches to a HART field device with 18-inch leads and test clips. The PC host uses an internal Bluetooth interface or a USB-to-Bluetooth converter to communicate with the modem.
