to equipment.
Several communication options are available for the PM130:
COM1: RS-485
COM2:
Ethernet 10/100BaseT
Profibus DP
GPRS
RS-232 or RS-422/485
A connection to the Ethernet connector is made through a cable adaptor
provided with your meter.
A full description of the communication protocols is found in the PM130
protocol guides that come with your meter.
