AL5740 Honolulu Users Guide

OVERVIEW

This document is a users guide to explain how to establish a wireless connection using an Alereon HWA and an AL5740 Honolulu board.

1.0 INSTALLATION

There are two software packages necessary to use the AL5740 Honolulu board with the AL5604 or AL5616 Host Wire Adapter (HWA).

• The Wireless USB Manager - This software package includes the drivers for the HWA.

• The DispalyLink Driver Package - This software package contains the drivers necessary to enable the video output of the Honolulu
board.

1.1 Installing the Wireless USB Manager

Alereon provides MSI based installers. Each installer is designated by the platform it supports in the filename. For example,

• Setup_wusb_X86_XXXX.msi - indicates that this MSI is for 32 bit systems

• Setup_wusb_X64_XXXX.mdi - indicates that this MSI is for 64 bit systems

You can launch the installation process by double clicking the MSI package. Please follow the following steps in order to install Alereon's
Wireless USB Manager.

Note: Wireless USB Manager has a dependency on Microsoft .NET 2.0. you will have to install this software manually before going through the setup or

connect the PC to the internet and the setup will automatically download this dependency from the internet. Microsoft .NET is included in Windows
Vista and newer operating systems.

Step 1: Complete the installation of the Wireless USB manager by running the included Wireless USB installer. If you need
more detailed instructions for this please see the included Wireless USB Manager User’s Guide.

Step 2: Insert the HWA in to an open USB port on the PC and allow the drivers to load.

1.2 Installing the DisplayLink Driver Package

Alereon provides an installer package for the DisplayLink device on the Honolulu board. Installation of this driver package is necessary to
enable the video output of the Honolulu board. The DisplayLink installer files are named in this manner:

• Displaylink-5.X.XXXXX.exe - The X’s indicate the driver package version. You can launch the installation process by double clicking the

exe file. Please follow the following steps in order to install Alereon's Wireless USB Manager.

Note: In some cases, separate driver packages will be included for the various supported operating systems.

Step 3: Run the DisplayLink installer.

Step 4: Reboot the PC. If you choose not to reboot, the Honolulu video output may not work correctly until a reboot is

completed.

2.0 ESTABLISHING A WIRELESS CONNECTION

Step 5: Open the Wireless USB manager and select the "Connection Rules" tab.

Step 6: Click the On/Off button under "Wireless Associations". The button should turn green. If this button is disabled, please

ensure that the HWA drivers are properly loaded. Please see the Wireless USB Manager User’s Guide.

Step 7: Connect the power cable to the AL5740 Honolulu board. You must do this within 3 minutes after enabling wireless
associations in the Wireless USB Manager.

Step 8: After a few seconds, the Wireless USB Manager should report that a device wants to wirelessly associate. When this
happens enter the PIN "Alereon!". The A is capitalized and there is an exclamation mark at the end. The quotes are not part
of the PIN.

Step 9: The PIN association should succeed and the in a few seconds the device should connect and enumerate. If the PIN
association was successful but the device fails to connect, power cycle the device and it should connected within a few
seconds. If for any reason this process fails to prompt you for a PIN please remove the HWA and remove power from the
Honolulu board, then repeat steps 5 to 8.

Step 10: Your Honolulu adapter should now have a wireless connection to the host PC. Connect a monitor or TV using a VGA
or HDMI cable and enjoy.

3.0 USAGE NOTES AND RECOMMENDATIONS

• Optimal Resolution for Video performance - The DisplayLink drivers perform more advanced video compression when TV specific
resolutions are used. When typical PC resolutions are used, the video performance may be degraded in some cases. The recomm­mended output resolutions for the Honolulu board are 640X480, 720x480, 800x600 and 1280x720. Choosing other resolutions could
degrade video performance.

• Changing the Resolution (Windows XP and Vista) - You can change the resolution of the Honolulu attached display using the Dis-
playLink Manger which can be found in the Windows system tray. The icon has a blue monitor with a wire attached. An example is pro­vided to the right of this paragraph.

• Changing from Mirror to Extended Mode (Windows XP and Vista) - You can change the mode of the Honolulu attached display
using the DisplayLink Manger which can be found in the Windows system tray. In Mirror mode, the image and resolution of the main
display is also used on the second display. In extended mode, the resolution output of the Honolulu can be changed indepen­dently of the main PC display.

• Windows 7 - The Mode and resolution of the Honolulu attached display must be changed through the display resolution settings
included in Windows 7. To access this functionality right click on the desktop and select "display resolution".

• Playing Full Screen Video in Windows XP - The DisplayLink drivers have a limitation when playing full screen Flash video. Typical
examples of Flash video are YouTube and Hulu. The workaround for this is to disable hardware acceleration in the flash video. On most
PC’s this changed is retained by the flash player, so these steps should need to be performed only once. Here are the steps to perform
this workaround:

•1. Right click on the flash video, select Settings

•2. Go to the Display card

•3. Uncheck "Enable hardware acceleration"
