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