PM175 Quick Start Guide
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. Depending on
what was ordered, the COM1 port is equipped with an RS-232/RS-422/RS-485
serial interface, with a dial-up modem for communicating through public telephone
lines, or with an Ethernet module for communicating through the Internet.
To configure the PM175 communication via PAS:
1. Select Configuration from the Tools menu. Under the
Communication group of the Instrument Setup tab, select the
type of a connection for your device.
2. Enter the device communication address you assigned to the
PM175.
3. In the Sampling Rate box, select a rate at which PAS updates
data on your screen when you continuously poll the device in
the PAS Data Monitor.
The communication protocol and port settings in PAS must match the settings
made in your device.
COM1 Settings
Code Parameter Options Description
Prot Communications protocol ASCII, rtu*, dnP3 ASCII, Modbus RTU or DNP3.0 protocol
rS
Port Interface, depends on
order
232 = RS-232
