2. Attach the HART devices. For many HART input devices (such as transmitters),
you need to connect a 250 to 300 resistor in series with the power source.
Be very careful when connecting an output device in a non-DCS loop
configuration to avoid device damage. Always consult the device product
manual for detailed connection information.
3. Attach the modem leads across the resistor, if required.
4. Attach a power supply to the HART device, if necessary. Figure 1 shows how a
HART device should typically be wired to a modem.
5. Verify that the transmitter has power.
6. After configuring the modem, reboot the PC to complete the installation.
Note
Follow output device manufacturers’ recommendations for loop wiring.
Note
If a device is connected to the modem but its icon is not displayed, see “After a modem is
installed” on page 76.
