Overview
The 375 Field Communicator is a communication interface device. It supports HART and
Fieldbus devices letting you configure and troubleshoot in the field.
The 375 Field Communicator includes an LCD with touch-screen display and keypad. Use touch-
screen or keypad to enter data into 375 Field Communicator.
Three terminals for the lead set are on the top of the 375 Field Communicator. The lead set and
the terminals let you connect the 375 Field Communicator to a device. An access door ensures
only one pair of the terminals can be used at any time. Several markings indicate which pair of
terminals is for which protocol. The "F" indicates the Fieldbus protocol while "H" indicates the
HART protocol.
The infrared port (IrDA) lets the 375 Field Communicator interface with the PC. IrDA is a PC
interface supported for transfer of device descriptions (DD), software update, configurations
and application licenses. IrDA communication can either be built into the PC or provided
through a USB to IrDA adapter. The PC application can either be AMS Suite or 375 Easy Upgrade
Programming Utility. The 375 must be in the "Listen for PC" mode when communicating
through IrDA.
Refer to the 375 Field Communicator User Manual for details.

resistor,
. The HART connections are not polarity sensitive. A minimum 250 ohms
resistance must be present in the HART loop for the 375 Field Communicator to function
properly.
Explosions can result in death or serious injury. Do not make connections to the Field
Communicator's serial port, digital signal line, or NiCad recharger jack in an explosive
atmosphere.
