•
Adapters as required (for example, 9-pin to 25-pin)
Procedure
1. Attach the signal converter to the serial port or USB port on your PC.
2. Start ProLink III.
3. Choose Connect to Physical Device.
4. Set Protocol to Service Port.
Tip
Service port connections use standard connection parameters and a standard address. You do not
need to configure them here.
5. Set the PC Port value to the PC COM port that you are using for this connection.

B.2.3 Make a HART/Bell 202 connection
Prerequisites
•
ProLink III is installed and licensed on your PC
•
One of the following:
—
RS-232 to Bell 202 signal converter
—
USB to Bell 202 signal converter
•
An available serial port or USB port
•
Adapters as required (for example, 9-pin to 25-pin)
CAUTION
If you connect directly to the mA terminals, the transmitter's mA Output may be affected. If you are using
the mA Output for process control, set devices for manual control before connecting directly to the mA
terminals.
Procedure
1. Attach the signal converter to the serial port or USB port on your PC.
2. To connect to 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 to achieve at least one volt across the connection points.
