HART® (Highway Addressable Remote Transducer) connections are made on the 4-20mA output of the GF UD2100. The GF
UD2100 must be equipped with the optional serial communication card for the Communication menu to appear, and for the HART
option to be able to be selected in the Communication menu. 4-20mA output location:

DD files allow the user's handheld HART communicator to fully configure the GF
UD2100. GF provides DD files for the Emerson 475 Communicator. The files are
included in the USB drive provided with your GF UD2100 flow meter. You may
also request the files from GF by calling or emailing us at info.ps@georgfischer.
com. Warning: The GF UD2100 and associated DDs are pending certification from
the Fieldcomm Group.
HART Protocol uses a digital signal superimposed on the 4-20mA output. When
the 4-20mA output of the GF UD2100 is connected with a load resistor (230Ω to
600Ω), the HART communicator can be connected on the loop in order to
communicate.
