Field Communicator

The Field Communicator exchanges information with the transmitter from the control
room, the instrument site, or any wiring termination point in the loop. To assist
communication, connect the Field Communicator in parallel with the transmitter, as
shown in
panel of the Field Communicator. Do not make connections to the serial port of the
NICAad recharger jack in explosive atmospheres. To use the Field Communicator in an
explosive atmosphere, the instruments in the loop should be installed according to
intrinsically safe or non-incendive field wiring practices.
When using a Field Communicator, configuration changes must be sent to the transmitter
using the "Send" key (F2).
For more information regarding the Field Communicator, see the
User Guide.
