WiPort™ User Guide 1022:: IInnttrroodduuccttiioonnWiPort is a wireless embedded device server that provides a network-enablingsolution based on the IEEE 802.11b wireless standard. WiPort allows OriginalEquipment Manufacturers (OEMs) to add wireless connectivity to their products byincorporating it onto a circuit board.The WiPort functions independently of a PC, providing a fully integrated solution thatcombines a processor, memory, 802.11b, 802.11g transceiver, and dual high-speedserial ports into a single compact module. It includes an operating system, anembedded Web server, and a full TCP/IP protocol stack. In addition, the WiPortsends email alerts and supports numerous other network communication protocols,including ARP, UDP, TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.Both Wired Equivalent Privacy (WEP) and Wireless Protected Access (WPA) areavailable for security. WEP uses an RC4 encryption algorithm with a 64-bit or 128-bitkey. This key jumbles the data before it is sent over the airwaves. WPA is moresecure because re-keying is required. With WPA, the re-keying of global encryptionkeys is required. This key is changed using TKIP for unicast traffic.For OEMs who wish to customize the user interface by employing common andfamiliar tools, the WiPort serves applets to a Web browser, resulting in interactiveWeb pages. This customization of HTML Web pages and configuration screenstailors the WiPort to fit unique requirements.CapabilitiesThe WiPort device server has the following capabilities: Communication between TCP and UDP to serial. Wireless interface (802.11b and 802.11g) with WEP or WPA protection. Ethernet interface. Email notification of configurable alarms and events. Upgradeable firmware. SNMP monitoring. Connects devices through a TCP or UDP data channel to computers or toanother device server. Contains a web server allowing presentation of custom content and easyconfiguration through the browser. Contains eleven programmable I/O pins used to monitor or control attacheddevices.ApplicationsThe WiPort device server connects serial devices such as those listed below towireless and Ethernet networks using the IP protocol family.
