Method 1: HART/Bell 202 temporary or hard-wired connection to transmitter or multidrop network
Note: This method is supported by RFT9739, RFT9712, and IFT9701/9703 transmitters, by Model 
1700/2700 transmitters with the analog outputs option board or configurable input/outputs options 
board, by Model 1500/2500 transmitters, by Model 2400S transmitters with the analog outputs option 
board, and by Series 3000 transmitters.
Using a VIATOR HART Interface, the PC can be connected directly to a transmitter’s primary mA 
output terminals, to the output wires from these terminals, or to any point in a multidrop network that 
is wired to these terminals. Figure 2-1 shows the wiring for this connection type.

HART/Bell 202 temporary or permanent connection to transmitter or multidrop network
1. At the PC, connect the VIATOR HART Interface to the PC’s serial or USB port.
2. Attach the VIATOR HART Interface leads:
•
To any point on the network (hard-wired connection)
•
Directly to the primary mA output terminals on your transmitter (temporary connection). 
See Table 2-6
•
To the output wires from the primary mA output terminals on your transmitter (hard-wired 
connection). See Table 2-6
The connection is polarity-insensitive; you can attach either lead to either terminal. For 
assistance in identifying the primary mA output terminals, see Appendix A.
