Setting the Communications

You communicate with the meter via a changeable COM1 communication port, or
through a second factory set serial RS-485/RS-422 COM2 port.

Communications Connections
Several communication options are available for the PM172:

• COM1 (check the label on the back of your meter):

RS-232/RS-422/RS-485
56K Dial-up modem
Ethernet 10/100BaseT
Profibus DP

• COM2:

RS-422/RS-485

The RS-232/RS-422/RS-485 port is the standard port for COM1. Other options are
ordered separately. Connections to the Ethernet RJ45 connector and to the

telephone RJ11 connector are made through a cable adaptor provided with your
meter (if ordered).
A full description of the communication protocols is found in the PM172 protocol
guides provided with your meter.
