AND
PRECAUTIONS
The 375 Field Communicator supports HART and
FOUNDATION fieldbus devices, letting you configure or
troubleshoot in the field. When using the 375 Field
Communicator, follow all standards and procedures
applicable to the location. Failure to comply may result in
equipment damage and/or personal injury. Be sure to
understand and comply with the following items:
375 Field
Communicator
Components
• The 375 Field Communicator includes an FSTN type
LCD with touch-screen display, a Nickel-Metal
Hydride (NiMH) Battery Pack or Lithium Ion (Li-Ion)
Power Module, an SH3 processor, memory
components, and integral communication and
measurement circuitry.
• Three terminals for the lead set are on the top of the
375 Field Communicator. The lead set and terminals
let you connect the 375 Field Communicator to a
device. Each red terminal is a positive connection for
its protocol, while the black terminal is a common
terminal shared by both protocols. An access door
ensures only one pair of terminals is exposed at any
one time. Several markings indicate which pair of
terminals is for which protocol.
• The infrared port and card reader let the 375 Field
Communicator or its System Card interface with a PC.
• Use the keypad or touch screen to enter data into the
375 Field Communicator.
WARNING
Using Windows Explorer and a card reader to transfer files between the System Card and a PC
can corrupt the System Card. This operation should only be performed under the direction of
Technical Support personnel.
WARNING
The touch screen should be contacted by blunt items only, preferably the stylus included with the
375 Field Communicator. Using sharp instruments, such as screwdrivers, can cause failure of
the touch-screen display and void the warranty. Repair of the touch screen requires replacement
of the entire 375 Field Communicator display assembly, which is possible only at an authorized
service center.
