7. Set Protocol to HART Bell 202.
Tip
HART/Bell 202 connections use standard connection parameters. You do not need to
configure them here.
8. If you are using a USB signal converter, enable Converter Toggles RTS.
9. Set Address/Tag to the HART polling address configured in the transmitter.
Tips
• If this is the first time you are connecting to the transmitter, use the default address: 0.
• If you are not in a HART multidrop environment, the HART polling address is typically left
at the default value.
• If you are unsure of the transmitter’s address, click Poll. The program will search the
network and return a list of the transmitters that it detects.
10. Set the COM Port value to the PC COM port that you are using for this connection.
11. Set Master as appropriate.
