Phidget SBC Configuration

Configure the Router

Wireless routers use channels 1 - 11 (G mode). Before you configure the router's access point (AP) use an application such as NetStumbler -  http://www.netstumbler.com (XP) or InSSider 2 http://www.metageek.net/products/inssider (XP, Win7) to survey the neighbourhood where the router will be used.

If you detect other wifi sources, note the channels and relative strengths. You need to set the access point to an unused channel. The best choices are channels 1, 6, and 11. The other channels are overlaps and strong, nearby signals will interfere. If the neighbourhood spectrum is crowded and the main channels used, use the signal strength information to set the channel to the an intermediate where existing sources have the the weakest signal.

The Linksys WRT54GL is set to DHCP by default. You can leave it as a stand alone router if you won't be connecting to an actual network with Internet Access.

Configure the Phidget SBC

Plug the computer and the SBC into the router (LAN ports). Since the router is set for DHCP they will pick up an IP address automatically when powered on.



The SBC can be accessed by running the Phidget Webservice from the task bar. You can either double click on the SBC link to open a browser or note the IP address at the bottom of the webservice window and enter it in the browser address window.



If the SBC has not been setup before or if it has been reset (push and hold the reset button for 10+ seconds), the first screen requires you to set a password. (Press the small set button when done.)

Upgrade the Firmware

The firmware used to control the SBC must be compatible with the version of the Phidget Webservice installed on your computer. It is best to visit the Phidgets website (http://www.phidgets.com) and download the latest version of both.

To install the firmware, navigate to the System Tab and click the Upgrade Tab.


When the Upgrade window opens, click the Browse button, find the downloaded firmware, and click Upgrade.



The upgrade won't take too long and the unit will reboot when it is done.

Configure the Ethernet Adapter

The next step would be to static address both the ethernet and wireless network adapters. You can't program an application unless you know the IP address of the SBC.

Click the Network tab and select Network (it should be the default)



Under TCP/IP settings, select Static and type an address that is not in use. If you are using the Linksys WRT54GL router as your access point, the default network is 192.168.1.x. The router is 192.168.1.1 and this is the Default Gateway. The DNS is the same as the Gateway in this case.



When the configuration is finished, click the Save button and then click Commit (and wait).



You will lose communication with the SBC because you have changed the IP address. Type the new IP address in the browser address window to re-connect.

Configure the Wireless Adapter

Now you must repeat the steps to statically address the wireless network adapter.  In addition, you must identify and connect to an access point. Make sure the USB wireless adapter is plugged in!

From the main Network tab, click the Wireless tab.

Choose the appropriate access point and enter the security password or key. If your access point is not broadcasting an SSID you will have to enter it manually.

Fill in the IP address, netmask, and gateway. The IP address should be different than the IP address of the wired ethernet adapter.



Click the Add This Network button. The selected wireless access point will be displayed as illustrated next.



Select the radio button and click Join This Network



If you don't see an indication that the adapter has joined the access point check the security key / password, and the TCP/IP settings.



Finally, save and commit the changes

Configure the Web Cam

onnect the web cam to the SBC's USB port.

Select the Webcam tab.

Select the Enable radio button.

Click Save and commit the changes



You should see a picture from the webcam. If not, try setting a lower frame rate.
