Router 1 to 5 and default router (gateway) settings
The ET-LAN unit can communicate not only with the destination nodes on the source network, but also
with destination nodes on other networks, through the router.
There are two types of communication that can be carried out with destination nodes on other networks,
as described below.
(1) Communication with destination nodes on adjacent networks registered in advance (Other networks
1, 2, 3, ... in the diagram).
(2) Communication with destination nodes on any other desired network (Other networks A, B, C, ... in
the diagram)
With the ET-LAN unit, with regard to the routers on the source network through which the type of
communication described in (1) is handled (there may be up to five of these routers), the IP address(es)
of the router(s) and the network (sub-network) address(es) of the adjacent network(s) connected through
the router(s) are registered in the routing information. The router on the source network through which
the communication described in (2) is handled is called the default router (gateway), and the IP address
for this default router is also registered in the routing information.
