375 FIELD
COMMUNICATOR
The HART Communicator exchanges information with the transmitter from
the control room, the instrument site, or any wiring termination point in the
loop. To facilitate communication, connect the HART Communicator in parallel
with the transmitter (see Figure 2-6). Use the loop connection ports on the
rear panel of the HART Communicator. The connections are non-polarized.
Do not make connections to the serial port or the NiCad recharger jack in
explosive atmospheres. Before connecting the HART communicator in an
explosive atmosphere, make sure the instruments in the loop are installed in
accordance with intrinsically safe or non-incendive field wiring practices.
When using a HART Communicator, any configuration changes made must
be sent to the transmitter by using the “Send” key (F2).
For more information regarding the 375 Field Communicator, please see the
375 Field Communicator Reference Manual

HART Menu Tree
Options listed in bold type indicate that a selection provides other options. For
ease of operation, changing calibration and setup, such as sensor type,
number of wires, and range values, can be completed in several locations
The review menu lists all of the information stored in the Rosemount 248. This
