Method 8: HART/Bell 202 temporary connection to HART clips
Note: This method is supported by Model 2400S transmitters that support HART communication.
Using a VIATOR HART Interface, the PC can be connected directly to the HART clips on the face of
the transmitter. Figure 2-9 shows the wiring for connection to the HART clips.
1. At the PC, attach the VIATOR HART Interface to the PC’s serial or USB port, using a 25-pin
to 9-pin adapter if necessary.
2. At the transmitter, remove the housing cover.
3. Connect the HART interface leads to the HART clips.

4. If necessary, add a resistance across the HART clips. The VIATOR HART interface must be
connected across a resistance of 250–600 Ω. Note that the HART clips use the same circuit as
the mA output, so the required resistance may already be installed if the mA output loop is
connected to a remote device or a HART network (see Figure 2-1).

(1) On Model 2400S transmitters, service port connections are made via the service port clips which are located on the user interface.
Alternatively, service port connections are possible via the transmitter infrared port. For more information on using the infrared port,
refer to the transmitter configuration and use manual.
