Connection via HART modem
Procedure
1. Connect the HART modem using the connection terminals 5 and 6 or the eyes 7 and 8 of the
WirelessHART adapter.
– If the modem has an installed communication resistor, it must be switched on.
– If the modem does not have an installed communication resistor, connect a resistor
parallel to the HART modem and connect it to eyes 7 and 8:

– If the WirelessHART adapter is operated with a field device in a control loop with
communication resistor, the communication resistor of the HART modem becomes
obsolete.
2. Start the computer and then plug the connection plug of the HART modem into the port

.
– If you are using a USB port, the computer will recognize the new hardware. Install the
device driver according to steps 3 to 6.
– If you are using a RS-232 port, it is automatically connected to the corresponding COM
communication port. Steps 3 through 7 will become obsolete in this case.
