3 Setting the PLC Modem

3 – 1 Communications Settings for the PLC Modem

Modems can detect the communication settings automatically to communicate with the

computer when the computer sends the AT command to the modem. That is why you do not

need to set the communications settings for the computer modem.

However, the PLC modem cannot detect the communications settings, because PLC is not a

computer and does not send the AT command to the modem. The communications settings for

the PLC modem must match the settings of the computer modem and the PLC.

Modems can detect the

communications settings

automatically to communicate with

the computer when the computer

sends the AT command to the

modem.

The communications settings

for the PLC modem must

match the settings of the

computer modem and the
