A. PC
B. RS‐232 to RS‐485 converter
C. Transmitter with end‐cap removed
Note
This figure shows a serial port connection. USB connections are also supported.
3. To connect over the RS-485 network:
a. Attach the leads from the signal converter to any point on the network.
b. Add resistance as necessary.
c. Ensure that the PLC or DCS is not trying to communicate to this meter at this
time.
Restriction
The meter does not support concurrent connections from ProLink III and a PLC or DCS. If
another host is already communicating with the meter, ProLink III will not be able to
connect, but its connection attempts will corrupt messages from the other host. To make
a ProLink III connection, you can temporarily stop host communications or you can
disconnect the cable from the host.
