1.2 Application Examples
The Wi232 has a serial port, an Ethernet port and an 802.11b transceiver. You can enable either the Ethernet
port or the Wireless LAN. The serial port connects to the serial communication port of your device. The
wireless transceiver connects to another wireless device or to an Access Point (AP) connecting to a network
through an Ethernet link.
This section includes four typical scenarios for using the Wi232.

Wi232
A PC connected to an Access Point via an Ethernet connection and a laptop with a wireless connection to
the Access Point LAN access the Wi232 as though they are directly connected to it. The combination of the
Wi232, a PC, and Redirector software allows the PC to directly communicate to the Wi232’s serial devices,
providing wireless serial tunneling.

In the above example, the Access Point is not present. The laptop makes a direct wireless connection with
the Wi232 to manage serial devices. Without an AP, it is a peer-to peer relationship.
