8.HART COMMUNICATION
8.1 Connection and Requirements
A standard HART communicator can be used for programming the YTA70.
The HART communicator must be loaded with the appropriate DDL driver
for YTA70.
Minimum loop resistance is 250Ω. If the receiving equipment has a lower
resistance, a serial resistor must be inserted to communicate with the
HART communicator.
