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:
