Connecting to a HART Field Device
The Viator RS-232 Interface has a female 9-pin DB-9 serial port for
connecting to the computer. The standard interface has an integrated
6-foot connector cable terminating in 2 polarity-insensitive test clips.
The interface connection to the HART network is transformer isolated
and polarity insensitive. Transformer isolation allows you to connect
the interface across the load resistor or across the HART device.
Polarity insensitivity means that you may attach either test clip to
either side of the HART device or load resistor.
