1] Marvell Configuration Utility

1.1] Overview

The Marvell Client Card Configuration utility is a Windows based application that allows
configuration and management of the Marvell high throughput client cards. The
configuration utility sets up profiles, and performs other wireless network management
tasks. The Marvell Client card configuration utility comes in an executable file. Running
the executable file opens up the setup window. Following the instructions on screen will
install the configuration utility. For details on installing the Marvell Client card
configuration utility, please refer page 41.

Note:

For windows XP and Windows Server 2003, it is preferable to use the Marvell
configuration utility when using Marvell client cards. Windows Zero Config and Marvell
Configuration Utility cannot be used at the same time. In such a case, it is preferable to
disable or manually stop the services running Windows Zero Config utility. Please refer
page 54, on how to manually stop the Windows Zero Config service.

2] Bringing up the Setup

This section provides the details on

1. Drivers for UAY-MMC85M cards

2. Steps to use the Dbgview.exe utility to see radar detection and other logs.

3. Steps to bring up the Ad-Hoc setup

2.1] Driver for UAY-MMC85M cards

The UAY-MMC85M has two versions of the same driver. These drivers are used for the
following purpose:

1. To detect the radar in test mode

This driver version is used to detect the radar pulses, but not switch channels. This

mode is known as test mode and used to count the number of radar pulses detected.

2. To detect the radar and switch channel

This driver version is used to detect the radar pulses and switch to a new channel.
In this case the UAY-MMC85M switches channels anytime it detects radar. This is
used to determine the moving and closing time of the channel switching.

2.2] Dbgview Utility

The current logs of the setup are displayed in the Dbgview utility window. It displays
when the channel availability check has started on a particular channel and whether it has
detected the radar or not. It also displays the channel switching process on the master and
the new channel, the master has switched to. The Dbgview icon is encircled below.

2.3.1] Using UAY-MMC85M switch mode driver

The following section provides steps to bring up the setup to test the master for radar
detection purposes. Please remember to use the test mode driver for these detections. In
case of finding the channel move time, the closing time, it is advised to use the channel
switch mode driver. The procedure below describes the steps to change the drivers.

1. On the Master laptop, double click on the Dbgview.exe icon to open it.

2. Double click on the Marvell GUI icon to open the GUI window.

3. Plug in the UAY-MMC85M master PCIe extender assembly in the laptop. The

laptop screen should look like below.

4. The UAY-MMC85M driver starts the CAC and after a period of at least 60

seconds, brings up the UAY-MMC85M card, if no radar activity is seen in the
channel 120. The Waiting for peer status is seen in the Marvell GUI.

5. Now follow steps 1, 2 and 3 on Slave laptop to bring up the slave UAY-

MMC85M.

6. The association between the master and slave takes place. The Network Status

tab shows the Status as Connected.
The status on the Marvell GUI should be seen as below. Please refer the page 37,
section 3.1, in chapter Debugging Ad-Hoc Setup if there are problems in
association.

2.3.2] Changing UAY-MMC85M driver

In the previous section, the UAY-MMC85M would switch channel whenever radar was
detected in the operating channel. The following section provides steps to change the
driver so that the master/slave would just detect the radar. This means that UAY­MMC85M will not switch the channel and give a count of the number of radar
detections. The procedure below describes the steps to change the drivers.

1. Open the folder C:\Documents and

Settings\admin\Desktop\DFS\dfsbuilds\fcc2006.

4. Go to C:\Windows\system32\drivers and paste the copied file.

5. Unplug and plug the UAY-MMC85M master assembly. The UAY-MMC85M

master / slave now has the test mode driver.

6. All the tests to count the number of radar detects can be carried out. The radar

detection count and logs will be seen on the Dbgview.exe window.

3] Debugging Ad-Hoc Setup

3.1] Slave does not associate with the Master

Sometimes the Slave would not join the Ad-Hoc network and would start the radar mode
channel availability process. This can be seen when a message shown below is seen in
the Dbgview window.

When such messages are seen in the Dbgview window on the slave, do the following:

1. Unplug the Master and the Slave UAY-MMC85M assemblies.

2. Plug in the Master assembly first.

3. Wait for the CAC time period, until the Dbgview window in Master shows the

message Starting adhoc network on channel.

4. Plug back the Slave assembly and wait for association to take place.

Page 39 Marvell® Proprietary. V 1.0

MMC85M wireless cards

Marvell AppNote

AN -xxxx

5. Please follow the steps 1-4 a couple of times, in case association does not take

place.

3.2] Link Instability

Sometimes the link between the Master and Slave can be quite unstable. In such a case,
please look for any loose connections in the setup. Please confirm that all the pads have
correct attenuation.

3.3] Video cannot be played

This can happen due to improper channel loading. In such cases, look at the Tx/Rx Rates
as seen in the Network Status tab below. If the rates stabilize around 6Mbps, the video
file cannot be played, even though the ping between the master and slave is successful. It
is preferred to unplug both the UAY-MMC85M extender assemblies and plug them back
starting with the Master assembly.
