Note
This figure shows a serial port connection. USB connections are also supported.
3. To connect from a point in the local HART loop:
a.
Attach the leads from the signal converter to any point in the loop.
b. Add resistance as necessary.
Important
HART/Bell 202 connections require a voltage drop of 1 VDC. To achieve this, add
resistance of 250–600 Ω to the connection.
