    Chapter 3. Modem Configuration 3.1 Configuration The modem must be configured by the WM-E Term software by configuring its ® parameters which must be performed before the normal operation and usage. Over the parameter settings of meter, modem and communication, etc., you can also test the modem communication by the configuration program.
