Introduction:
=============

  This document shows you how to setup the driver in Windows CE 5.x operating system.


Installation:
=============

  Before starting with the installation process, make sure that the adapter
  is properly installed and configured.


    1. System hardware configuration:
       You should add USB OHCI, UHCI or EHCI(for USB 2.0) support in your platform design.

    2. Driver Installation:
       Please run VNUWLC5.MSI, it will copy all the driver files to the target
       installation directory:
       $(_WINCEROOT)\3rdParty\VNT\VNUWLC5\

       Also, VNUWLC5.MSI will import VNUWLC5.CEC to the catalog.

       The path of the driver in catalog menu is
       "Catalog\Third Party\Device Drivers\Networking\Local Area Networking (LAN) devices\
        VNT VNWLC5 Wireless LAN".

       If "VNT VNUWLC5 Wireless LAN" is not listed in catalog
       menu, please right click on "Catalog" node, then select "Refresh Catalog".

    3. Create and build a new platform:
       Assume a new platform based on CEPC:X86 BSP is created in Platform
       Builder 5.x and choose a suitable platform configuration such as
       Internet Appliance or Set-Top Box.

       Right-click on the "VNT VNUWLC5 Wireless LAN" in the
       catalog and select "Add to OS Design".

    4. To add the Windows Zero Config function into the platform, 
       drag the network driver named "CISCO Aironet 340/350 PCMCIA WLAN Card" 
       in the catalog menu into the workspace (features) window. 
       The path of the driver in catalog menu is
       "Catalog\Device Drivers\Networking\Local Area Networking (LAN) devices\
       CISCO Aironet 340/350 PCMCIA WLAN Card". 

    5. Modify the registry settings if necessary:
       You may need to modify the default registry settings in VNUWLC5.REG if necessary.
       Find details in Note 2.

    6. Select "Sysgen" from the "Build OS" menu.

    7. Download the binary image to your target platform.


  Note:

    1. Basic connection testing:
       On the development workstation, open a command prompt and type:

         ping  <IP address of the target device>

       As an example, if the network card's IP address in the target platform
       is 192.168.60.100, then type:

         ping 192.168.60.100

       If the driver is installed correctly and the network card works
       properly, the following messages will appear on the development workstation:

         Pinging 192.168.60.100 with 32 bytes of data:

         Reply from 192.168.60.100: bytes=32 time<10ms TTL=32
         Reply from 192.168.60.100: bytes=32 time<10ms TTL=32
         Reply from 192.168.60.100: bytes=32 time<10ms TTL=32
         Reply from 192.168.60.100: bytes=32 time<10ms TTL=32

       Note values for "time" and "TTL" may vary from system to system.
       If the network card or the driver itself fails to work properly,
       the following messages will appear on the development workstation:

         Pinging 192.168.60.100 with 32 bytes of data:

         Request timed out.
         Request timed out.
         Request timed out.
         Request timed out.

    2. Update registry VNUWLC5.REG:
       In Workspace's "FileView" Tab, edit Projects->VNUWLC5->Parameter files->VNUWLC5.reg
       as needed.

       After modifying it, Select "Sysgen" from the "Build OS" menu.

       Read below for more information on how to configure the driver settings.

       The VNUWLC5 drivers use several registry sub-keys under the
       [HKEY_LOCAL_MACHINE\Comm\VNUWLC51\Parms] key.

       TransmitBuffers
       Internal driver buffers for packet transmit.

       ReceiveBuffers
       Internal driver buffers for packet receive.

       Channel
       User chosen connection channel; it only used in ad-hoc mode

       ConnectionRate
       1M, 2M, 5.5M, 11M, 6M, 9M, 12,M, 18M, 24,M 36M, 48M, 54M, Auto Rate.

       FragThreshold
       When the packet size is larger than fragmentation threshold, it will be fragmented.

       RTSThreshold
       When the packet size is larger than fragmentation threshold, it will be send by using RTS-CTS mechanism.

       OperationMode
       Infrastructure or Ad-hoc mode.

       BeaconInterval
       It defines beacon interval in Ad-Hoc mode.

       DesiredSSID
       User defined SSID; driver will auto-connect to Desired SSID when driver starts.

       Long Retry Limit
       It means how many times this card should resent a packet which corrupted when the packet size is larger then RTS threshold.

       PreambleType
       Long: It means this card always use long preamble.
       Short: It means this card can support short preamble capability.

       RadioControl
       It defines Radio ON/OFF.

       The sub-keys under [HKEY_LOCAL_MACHINE\Comm\VNUWLC51\Parms\TcpIp]
       are addresses for IP, gateway, and subnetmask. The listed values
       are used as an example, and these keys must be
       modified according to your actual network environments.

       If a DHCP server exists in your network, set the sub-keys as below
       to enable the DHCP configuration,

         [HKEY_LOCAL_MACHINE\Comm\VNUWLC51\Parms\TcpIp]
               "EnableDHCP"=dword:1
               "DefaultGateway"=""
               "UseZeroBroadcast"=dword:0
               "IpAddress"=""
               "Subnetmask"=""
               "DNS"=""
               "WINS"=""

       If you want to use static IP address, set the sub-keys as below

         [HKEY_LOCAL_MACHINE\Comm\VNUWLC51\Parms\TcpIp]
               "EnableDHCP"=dword:0
               "DefaultGateway"=""
               "UseZeroBroadcast"=dword:0
               "IpAddress"="192.168.100.10"
               "Subnetmask"="255.255.255.0"
               "DNS"=""
               "WINS"=""
