1: Using This Guide Purpose and Audience This guide provides the information needed to configure, use, and update the WiSpan. It is for network administrators, system integrators, and those responsible for installing and maintaining the WiSpan. Chapter Summary The remaining chapters in this guide include: Chapter Description 2: Introduction The main features of the WiSpan and the protocols it supports. 3: Hardware The WiSpan's connectors and LEDs.
1:Using This Guide Additional Documentation The following guides are available on the product CD and the Lantronix web site (www.lantronix.com) WiSpan Quick Start Provides instructions for getting your WiSpan up and running. DeviceInstaller Online Help Provides information on using DeviceInstaller to view current configuration settings.
2: Introduction 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.
2: Introduction 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.
3: Hardware 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).

4: Quick Start This chapter describes how to install and configure the WiSpan unit to get it up and running. You must configure the WLAN settings for the WiSpan to communicate on a wireless network. Note: You only need to configure the WiSpan's IP address and other network settings if you want to discover and configure your WiSpan device from the wired network; these settings only apply to communication on the Ethernet interface.
4: Quick Start Using the Ethernet Port To connect to and initially configure the WiSpan using the Ethernet port: 1. If a device is connected to the WiSpan's Ethernet port, disconnect it and connect a PC for configuring the WiSpan. 2. Set up the PC's Ethernet port for AutoIP or assign a static IP address in the AutoIP range (169.254.x.x). 3. Use a utility such as DeviceInstaller to locate the WiSpan’s MAC address and IP address. This utility must use the Lantronix access protocol to query the WiSpan.
4: Quick Start Server Settings To configure the Server (WiSpan) settings, select 0 Server from the Change Setup menu. The unit’s basic server (network) values display when you select Server (option 0 from the Change Setup menu). The following sections describe the configurable parameters within the Server configuration menu. Network Mode: The network mode (Bridging ). Set the IP Address: The unit has an automatically assigned IP address. To assign a static address, enter it manually.

Infrastructure mode communicates with Access Points. Ad Hoc mode communicates only with other clients. Topology 0=Infrastructure, 1=AdHoc (1) ? Network Name (SSID): Enter the name of the network to which the WiSpan will connect.
4: Quick Start The passphrase input is safer because it is up to 63 chars long. ASCII input is a maximum of 5 (WEP64) or 13 (WEP128) characters long and limits the number of key combinations. Please refer to the other equipment’s manual to determine the passphrase input style recommended. Note: Lantronix recommends using a passphrase of 20 characters or more for maximum security. TX Key index Select the WEP key used for transmissions from your access point. Enter a value from 1 to 4.
4: Quick Start Note: Lantronix recommends using a passphrase of 20 characters or more for maximum security. Encryption Set the type to the minimum required security level. The “+” sign indicates that the group (broadcast) encryption method is different from the pairwise (unicast) encryption. For example, for CCMP+TKIP, CCMP is the pairwise encryption and TKIP is the group encryption. Fixed or Automatic Data Rate WiSpan enables you to control of the transmission rate.
5: Using DeviceInstaller You can use DeviceInstaller, a utility on the product CD, to locate a WiSpan and manually assign it a static IP address, view its current configuration settings, and upgrade its firmware.
