It is therefore necessary to set up the IP routing function in the router
shown in Fig.3.4(d) in such a way that network A, to which the NCs
belong, can communicate with network B, to which the viewer PC
belongs, using TCP/IP. Set up the router in such a way that a port
number set up for a port for TCP in each NC can be routed.
NOTE
The method of setting up IP routing varies
depending on what router you use.
If you use i CELL and the CIMPLICITY viewer this
way, be sure to check the setting method in
advance.
The configuration shown in Fig. 3.4 (e) is an example of providing the
server PC with router functions and using two networks. Also in this
configuration, the viewer PC communicates with NCs, using
FOCAS2/Ethernet. It is necessary to set up the IP routing function in
the server PC in such a way that networks A and B can communicate
with each other, using TCP/IP. Set up the server PC in such a way that a
port number set up for a port for TCP in each NC can be routed.

Two NICs (Network Interface
Cards), A and B, are set in the
server PC to configure two
networks.
The server PC is provided with

NOTE
The method of setting two NICs in the server PC for
having the server PC operate also as a router varies
depending on what operating system you use in
your server PC.
If you use i CELL and the CIMPLICITY viewer this
way, be sure to check the setting method in
advance.
