Method 3: HART/Bell 202 temporary connection to RFT9739 rack-mount transmitters

1. At the PC, connect the VIATOR HART Interface to the PC’s serial or USB port.

2. Attach the leads of a Bell 202 cable to the leads of the VIATOR HART Interface, and insert the

cable prongs into the HART jack on the transmitter’s faceplate (see Figure 2-3). The

connection is polarity-insensitive; you can insert the cable prongs in either direction.

3. If necessary, add resistance in the loop by installing resistor R1 with a resistance of

250–1000 Ω

. Note that the hookups use the same circuit as the primary mA output, so the

required resistance may already be installed if the primary mA output loop is connected to a

remote device or a HART network.
