HART Communicator

C.3

Connections and hardware

The HART Communicator can interface with a transmitter from the control room, the instrument site, or 
any wiring termination point in the loop through the communicator connections as shown in 

Figure C-2

, 

Figure C-3

, and 

Figure C-4

. To communicate, connect the HART Communicator in parallel with the 

instrument or load resistor. The connections are non-polarized. Before connecting the HART 
Communicator in an explosive atmosphere, make sure the instruments in the loop are installed in 
accordance with intrinsically safe or nonincendive field wiring practices.

Note

The HART Communicator needs a minimum of 250 ohms resistance in the loop to function properly. The 
HART Communicator is not a measurement device and does not need to be calibrated; it is a 
communications device through which the transmitter configuration information can read and adjusted. 
All variable outputs displayed by the communicator are functions of the transmitter.

Note

Do not make connections to the serial port or NiCad recharger jack in an explosive atmosphere.
