The WiSpan is an industrial 802.11 b/g wireless-to-Ethernet bridge allowing
10/100 Ethernet-enabled devices to seamlessly connect and communicate over
802.11 b/g wireless networks. By bridging 10/100 Ethernet to 802.11 b/g, wireless
mobility can be added to Ethernet devices.
The WiSpan Ethernet bridge connects or bridges Ethernet devices to wireless networks
using the IP protocol.
Note: The Ethernet interface can only bridge a single wired device.
Typical applications of the WiSpan include:
Cash registers
POS terminals
Vending machines
Industrial equipment
Security panels
Protocol Support
The WiSpan Ethernet bridge uses the TCP/IP protocol stack for network
communications. Other supported protocols include:
ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, HTTP, and SNMP for network
communications and management.
TCP, UDP, and Telnet for connections to the setup port.
TFTP for firmware and web page updates.
IP for addressing, routing, and data block handling over the network.
User Datagram Protocol (UDP) for typical datagram applications in which devices
that support UDP interact with other devices without maintaining a point-to-point
connection.
Configuration Methods
For the unit to operate correctly on a network, it must have:
An IP address
Appropriate settings for network communications to an access point
(Infrastructure Mode) or for peer-to-peer connection (Ad Hoc Mode).
Methods for logging into the WiSpan to set configurable parameters include:
2: Introduction
WiSpan User Guide 9
Serial & Telnet Ports: There are two approaches to accessing Setup Mode: make a
Telnet connection to the network port (9999) or connect a terminal (or a PC running a
terminal emulation program) to the unit’s setup (serial) port.
DeviceInstaller: This utility provides a GUI interface for locating the WiSpan on the
network, assigning an IP address, viewing the current configuration, and updating
firmware.
Web-Manager: Once the unit has an IP address, you can configure the WiSpan and its
settings using the WiSpan’s web interface, Web-Manager.

The WiSpan has one setup (serial) port and one Ethernet port for setup and for
connecting an Ethernet device using a network crossover cable. It has an 802.11 b/g
transceiver that connects to another wireless device or to an Access Point (AP).
Following is a description of the serial and Ethernet connectors.
Serial Connector Pinouts
One DB9M DTE setup port provides default settings for RS-232C communications of
9600 baud, 8 bits, no parity, and 1 stop bit (9600, 8, N, 1). The only use of this port is to
configure the unit in Setup Mode.

Figure 3-2. DB9M DTE Serial Connector
Network Interface
The back panel of the WiSpan contains a 9-30 VDC power plug and an RJ45 (10/100)
Ethernet port. You may use the Ethernet port to configure the unit as well as to connect a
network-enabled device to the network using a network crossover cable.
