4PACKAGE CONTENTS & SYSTEM REQUIREMENTS Package 1. Manual (this document) 2. Drivers and configuration utilities on CD-ROM 3. Quick Install Guide If you miss any of these items please contact your reseller. System Requirements  PDA with Windows® Pocket PC 2002 and 2003 with at least 32 MB memory  Secure Digital (SD) slot (Assuming SDIO host controller and driver are already installed)  Microsoft® Active Sync® should be installed  An IEEE802.11b or Wi-Fi approved Access Point/Base station INTRODUCING SD WLAN CARD The SDW11B is a wireless network card that complies with the IEEE 802.11b standard on wireless LANs (Revision B). SDW11b features and benefits • Wi-Fi (Wireless Fidelity) certified (Expected in Q2/04). • Supports data rates up to 11 Mbps. • Fully compatible with any other wireless LAN system based on Direct Sequence Spread Spectrum (DSSS) radio technology that complies with the “IEEE 802.11b standard on wireless LANs (Revision B)”. • Automatic Transmit Rate Select mechanism in the transmit range of 11, 5.5, 2 and 1 Mbps. • 128 bit Wired Equivalent Privacy (WEP) data encryption and WPA support (WPA will be optionally supported in Q2/04). • Efficient Power Management. • Roaming over multiple channels. • Working range up to 400 meters in an open environment. • Supports Ad-hoc and infrastructure modes for easy wireless communication. SDW11b Wireless Network Scenarios • The SDW11b enables you to: • Connect your computer to a Peer-to-Peer workgroup of wireless computing devices • Connect your computer to a Small Office/Home Office (SOHO) network that includes Wi-Fi access points. • Connect your computer to a Local Area Network (LAN) Infrastructure that includes the SDW11b, or other IEEE 802.11b compliant LAN systems Wireless stations can be equipped with the SDW11b, but also with other WLAN PC Cards. Both the SDW11b and the WLAN PC Card share the same wireless functionality.
5Peer-to-Peer (Ad-hoc) Workgroup The Peer-to-Peer workgroup configuration enables you to quickly set up a small wireless workgroup, where the workgroup participants can exchange files using features like “Files and Printer Sharing” as supported by Microsoft® Networking. You can use this option to setup a temporary or Ad-hoc network in environments where no access points are available (for example in Small Office/Home Office “SOHO” environments). As long as the stations are within range of one another, this is the easiest and least expensive way to set up a wireless network. Home Networking With SDW11b, wireless access to the Internet or other devices is at your fingertips. All you need to do is connect the SD WLAN Card to an existing access point that may be connected to the external Cable TV or xDSL modems and you are ready to:  Share files and printers, and  Access the Internet. 2-2-3 Enterprise Networking With the Wi-Fi certified Access Point in the corporate network system, you can connect to a corporate Local Area Network (LAN) infrastructure to have wireless access to all network facilities. LAN Infrastructures may either be:  Stand-alone wireless LANs.  Wireless network infrastructures connected to an existing Ethernet network.

Insert the SDW11b into the PDA 3. Check the LED on the SDW11b. If steady Blue light is seen, the SDW11B is active. 4. (Optional) To check the quality of the network connection, you should use the SDW11b configuration utility program as described in the next section SDW11b CONFIGURATION UTILITY 1. Click Install Utility to perform utility installation. 2. Click “YES” to proceed the installation. Step 2
8 3. Click “OK” to complete the driver installation.

14TROUBLESHOOTING Introduction This chapter provides typical problems with their own specific troubleshooting tips. Common Troubleshooting Tips LED Activity If you encounter difficulty using and/or installing your SD WLAN Card product, the error may be related to various causes : - Out-of range situation, which prevents the SDW11b from establishing a wireless connection with the network. - Configuration mismatch, which prevents the SDW11b from establishing a wireless connection with the (correct) network. - Absence of, or conflict of the SDW11b Driver . - A problem or conflict with the SDW11b socket from powering on. - A conflict of the SDW11b hardware with another device. The starting point to troubleshoot problems with your SDW11b is looking at the LED activity of the SDW11b. LED Activity  The power LED will be blank when the SDW11b is properly inserted but not transmitting/receving data.  The Act LED will be blinking Blue when transmitting/receiving wireless data. Cannot Connect To Network If your SDW11b seems to be working fine, but you are not able to connect to the network, this error might be due to a configuration mismatch. For example if LED of your SDW11b lights, the problem is likely to be caused by a configuration mismatch of : - Network Name (The SDW11b Network Name is case-sensitive). - Encryption Key Other causes may be : - No driver loaded. - Station not authorized to access network. - SDW11b defect. The most common cause is simple mistake. First check whether the card is inserted properly or not. Check whether any APs are available or not. If you see many APs, select any of one those APs and click connect. If you don't see any APs click Rescan Button. If you still don’t see AP list after refscanning, it is possible that no active AP is nearby. You may be in the dead zone. Move around or change the PDA orientations. It may help. Cannot Find the AP Check the available access point in the neighborhood by clicking the Site Survey tab in the utility. If the access point requires WEP key, input the same WEP key then try to connect again. If you do not know the WEP key, contact the system administrator to obtain the appropriate key. For identifying the specific AP, check the wireless networks available in the neighborhood. If the AP shows ESSID, use the same ESSID to connect the AP. ESSID is assigned to the specific AP for that purpose.
15The System is Very Slow Some devices with non-powerful CPU may suffer their performance significantly. If the system is very slow, check - If you are opening many windows, close them - Change the antenna orientation for better signal reception - Check the signal strength if it is weak move toward the AP. SDW11b Does Not Operate After Returning From the Stand-by or Sleeping Mode This may happen when the driver is not functioning. Reinstall the SDW11b driver again.
