1.1.5 Connections Between Networks
With an Ethernet, communication is possible not only between the home network and a node, but also
between the nodes of other networks, using routers.
As shown in the illustration above, communication with nodes of other networks is classified as follows:
-
The router is registered in advance, and communication is carried out between partner nodes of
adjacent networks (other networks 1, 2, 3, etc. in the above illustration)
-
Communication is carried out with the partner nodes of networks other than those shown above (other
networks A, B, C, etc. in the above illustration)
Key Point:
When using the ET-LAN unit to carry out communication with partner nodes on another network, the
router used by the ET-LAN unit should be registered.
(1) Up to five routers can be registered for the source network, enabling communication with any of the
nodes on another adjacent network.
(See other networks 1, 2, 3 etc. in the left illustration.)
(2) Only a single default router can be registered, and communication carried out with any desired node
on any network other than those covered by (1), through the default router. (See other networks A,
B, C, etc. in the left illustration.)
The router may be one of the five routers specified at (1), or may be a different router.
