With its CF Type II extended form factor, low power consumption, advanced power management, and rugged design (with antenna on the card), the card is ideally suited for integration into your Pocket PC. It allows your Pocket PC to wirelessly gain access to corporate networks and thereby to share resources on the network, such as file transfers or Internet Access. This card features acknowledgment protocol and the option to be tuned to another frequency channel to ensure the wireless connectivity in environments with radio interference. This card transfers data at speeds of up to 11Mbps. Both Peer-to-Peer Group (also referred to as Ad-Hoc mode) and Access Point connection (also referred to as Infrastructure mode) are supported. For network security concern, it also provides 64-bit or 128-bit WEP (Wired Equivalent Privacy) encryption to ensure data security. 11..22 SSyysstteemm RReeqquuiirreemmeennttss To use this Wireless CF Card, you will need:

Quick Installation Guide 2 22 WWiirreelleessss LLAANN BBaassiiccss This section contains some Wireless LAN basics to help you better understand how the product can be used to create a wireless network. 22..11 LLooccaall AArreeaa NNeettwwoorrkk ((LLAANN)) Simply put, a LAN is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and peripheral devices such as printers. The Wireless LAN Card allows you to interact with other computers without having to run cables normally associated with networks. This lets you move your computer around while staying connected to your network. There are two ways to use the Wireless LAN Card. One way is to connect directly to one or more Wireless LAN Card equipped computers, forming an Ad-Hoc wireless network. The second way is to connect to an Access Point that gives you access to an existing wired LAN, forming an Infrastructure wireless network. 22..22 AAdd--HHoocc MMooddee Ad-Hoc mode offers peer-to-peer communication between wireless stations within range of each other, eliminating the need for an Access Point. When set to use Ad-Hoc mode, the wireless-enabled Pocket PC can connect to another Ad-Hoc peer, which could be other computer or Pocket PC equipped with 802.11b wireless adapter set in Ad-Hoc mode. A typical Ad-Hoc network may look like Figure 1-1 where all the wireless stations use the same SSID, channel, WEP settings (if enabled). They are in the same subnet and can share files by using TCP/IP and NetBEUI protocol. Figure 1-1 Ad-Hoc Mode 22..33 IInnffrraassttrruuccttuurree MMooddee The Infrastructure network uses an Access Point or several Access Points as a gateway, linking the wireless network to a wired LAN. As a result, portable workstations or desktops on your wireless network have access to all of the features of your wired LAN including e-mail, Internet access, network printers and file server. 3 Wireless CF Card User Manual 22..44 RRooaammiinngg Figure 1-2 Infrastructure Mode Multiple Access Points can be installed to extend the wireless service coverage area for seamless wireless access. Within an extended service area, all Access Points and wireless clients must have the same Service Set Identity
(SSID). Roaming among different Access Points is controlled automatically to maintain the wireless connectivity at all times. Figure 1-3 Roaming Across Multiple Access Points 4 33 IInnssttaalllliinngg tthhee DDrriivveerr aanndd CCFF CCaarrdd The software provided with the Wireless CF Card supports Windows CE 2.11, 2.12, 3.0 and 4.0. Most Windows CE devices use a host computer with Microsoft ActiveSynch software to synchronize data. Therefore you should synchronize your Pocket PC and a host computer before installing the driver and utility. The Wireless CF Card is to be inserted into your Pocket PC at the last stage. Follow the steps described in this chapter to complete the installation. Caution: DO NOT insert the Wireless CF Card into your Pocket PC before you install the driver. Step 1: Install Microsoft ActiveSynch. Please have Microsoft ActiveSynch 3.0 or higher installed on your host computer and hooked up to your Pocket PC. Most Windows CE devices came with ActiveSynch in the supplied CD-ROM. You can also download the latest version of ActiveSynch from Microsoft website. Step 2: Install the driver. Make sure your Pocket PC is connected to your host computer before proceeding. 1. Insert the provided Software Utility CD into the CD-ROM of the host computer. 2. Locate and run Setup.exe from D:\Utility&Driver of the Software Utility CD where D is the drive letter. 5 Wireless CF Card User Manual 3. When the Welcome screen pops up, click Next. 4. Click Yes to install the driver into the default directory. To change the directory, click No to locate desired directory and then click Yes to proceed. 5. If no additional steps are required on your Pocket PC as shown in the example figure below, just click OK. Otherwise you should follow the instructions on your Pocket PC before you click OK on the host PC. The screen on Pocket PC indicates the installation is complete. 6 6. Click Finish to complete the installation. 3. Installing the Driver and CF Card Step 3: Disconnect the Pocket PC from the host computer. Since the synchronization between the host computer and the Pocket PC has been completed, you may now disconnect your Pocket PC from the host computer. Step 4: Insert the Wireless CF Card. At the last stage, insert the Wireless CF Card into the Type II CompactFlash slot in your Pocket PC with the printed label facing up. If the card is securely inserted, the red LED should blink to indicate the wireless connection. Then you should be able to find the wireless icon in the system tray:
