Setup of an Ad-Hoc network using UAY-MMC85M wireless cards Marvell AppNoteAN -xxxx Page 23 Marvell® Proprietary. V 1.0 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.

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.

Setup of an Ad-Hoc network using UAY-MMC85M wireless cards Marvell AppNoteAN -xxxx Page 37 Marvell® Proprietary. V 1.0 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 UAY-MMC85M 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.

Select the file netmw145.sys and press Ctrl C to coy the file. 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.
Setup of an Ad-Hoc network using UAY-MMC85M wireless cards Marvell AppNoteAN -xxxx Page 39 Marvell® Proprietary. V 1.0 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.
Setup of an Ad-Hoc network using UAY-MMC85M wireless cards Marvell AppNoteAN -xxxx Page 40 Marvell® Proprietary. V 1.0 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.
Setup of an Ad-Hoc network using UAY-MMC85M wireless cards Marvell AppNoteAN -xxxx Page 41 Marvell® Proprietary. V 1.0 In case unplugging and plugging the assemblies does not increase the Tx/Rx Rates, do the following: 1. Go to the Profile manager tab on the Master. 2. Select the Default profile and click Apply. 3. Select the dfs120 profile.
