Note
To connect over a HART multidrop network:
a. Attach the leads from the signal converter to any point on the network.
b. Add resistance as necessary to achieve at least one volt across the connection
points.
Important
HART/Bell 202 connections require a voltage drop of 1 VDC. To achieve this, add
resistance of 250–600 Ω to the connection.
