(1) Setting of dialup router
Set the dialup router so as to connect received call (data communication) via public telephone line to
the LAN side. And then, set an IP address to be assigned to the dialup router and PC in remote
locations.
The IP address of the dialup router is recommended to be [192.168.1.254] and the IP address of a PC
to be assigned to the telephone line in remote locations is recommended to be [192.168.1.211].
Also, the IP address of the PC to be assigned to LAN must be set to [192.168.1.*] so as not to be the
same IP address as used in the system at site.
(2) Network setting of G-50A
Set the IP address, subnet mask, and gateway address of G-50A by means of the initial setting tool
for gateway address, set the IP address of the dialup router.

In case of setting to the same system, data communications are not available by way of the dialup line, because telecommunications data are
input from the LAN port of the PC.

A gateway address can not be set only from the initial setting tool. (Other addresses can be set from G-50A.)

As the IP address of telephone line is [192.168.1.211],
set the IP address of PC to [192.168.1.211] so as to
avoid competing against each other.
