Serial Port Topologies

1

In addition to the Ethernet Port Topologies for the 10Base-T port of
your WaveLAN/EC-S device (described in the previous pages), its
RS-232 port enables you setup the device for a number of wireless
serial network topologies as well.

Although many varieties of serial networks exist, all can be
simplified into the three examples described on the following
pages:

■

Station-to-Station Topology (described below).

■

Broadcast Topology (described on page 1-12).

■

Hybrid Topologies (described on page 1-13).

If you would like to use both the Ethernet and RS-232 serial
connections of the WaveLAN/EC-S, please refer to “Combining
Ethernet and Serial Topologies” on page 1-14.
