When a router is used between the server and viewer PCs
- Setting the router IP address
When using a router between the server and viewer PCs, you need to set
the default gateway address for each PC and the router IP address for
each NC. Set the IP address of the router as the default gateway address
and router IP address.
Because similarly to the server PC, the viewer PC uses
FOCAS2/Ethernet to communicate with NCs, you need to set up IP
routing for the router.
