Connect the unit to upgrade to a spare COM (serial) port on your PC or laptop. The serial cable must be a "one-to-one" cable and NOT a null modem cable. This is because a null modem cable has "transmit" and "receive" wires swapped, and so will not work. [. . . ] used by the Wi-Fi adapter. Make sure that `Use the following IP address' is selected and the IP address is similar to that shown (i. e. If it is an auto-allocated address (typically of the format 169. 202. x. x), change it to one beginning 192. 168, but NOT ending with 224. 226 as that's the ADDRESS of the WiSP!Do NOT change the Default Gateway setting (normally blank)! ¥ © § ! ¦ § © § ¡ ¢ ¡ ¦ ¡ § © ¨ § ¦ ¥ ¤ ¡ £ ¢ ¡ Page 9 Search for and Establish a Wireless Link to the WiSP On your Windows desktop, double click on the Edimax Wi-Fi icon in the system tray beside the clock. Press the `Profile ' button at the top of this window to set up a new profile and the press `Add' below the empty `Profile List', rather than just scan for available networks, as this method is quicker and much more reliable. Make sure the window is expanded to show the bottom half - press the button with the arrow in the bottom right corner of the unexpanded widow. Note ­ the `Add' button won't work unless the adapter is ON ­ the Radio icon should be green. There are two tabs to configure ­ `System Config. ' and `Auth\Encry. ' On the `System Config. ' Tab make sure the following parameters are set up: Profile Name and SSID are `XTA WISP' ­ all in UPPER CASE!Network Type is set to `Adhoc'; Leave all other settings at default. Now click on the `Auth. \Encry. ' Tab to set up the security as shown below: Set `Authentication' to `Open' and `Encryption' to `WEP'. This has effect on the security settings.

Make sure this is selected (it should be by default) and press `Activate' just below the list. Assuming the WiSP is powered up and within range, if `Network' is now pressed at the top of the window, a list of all available wireless networks in range should be displayed as below. The network that the adapter is connected to is shown by the blue arrow on the left hand side of the name in the list. The signal strength and link quality and noise level (based on dropouts per second) update in real time as the adapter is moved, and the transmit and receive throughput graphs show how much data is being sent along the link. Connection Problems: Try experimenting with the location of the PC relative to the WiSP ­ sometimes the case of the computer can shield the radio link. Also, try to ensure that the WiSP is not too close to the computer, or the radio link may saturate (overload). Check the Edimax and Windows Network icons in the system tray on the task bar ­ if there appears to be a problem, double click on the Edimas icon to display the interface utility. Please refer to page 10 for detailed instructions of how to check/re-establish a connection. Note that it can take anywhere between 1 to 3 minutes for a network link to become available again. Moving radio links are more likely to lose connections than stationary ones, so if the link appears to be dropping out, try to minimise movement until the link is re-established. Computer Problems: Please ensure all power-saving features are disabled on your computer. Depending on the version of Windows you are using, select power as `Always On', ensuring that the system never goes into stand-by. Note that stand-by operation can also be enabled through the `Alarms' tab (on a laptop/tablet, used for low battery situations).

Adjusting the baud rate is a simple procedure, but please follow the steps carefully and in order. Assuming you have an established connection to begin with, the software should run and immediately find the WiSP, as shown here. . . The WiSP is actually configured though a standard web browser, with all configuration settings and the web pages themselves, being sent back from the device. To open a connection to the WiSP, simply double click on it in the list (it is the only item shown above) or select it, and click on "Open web interface" from the choices of Device Tasks on the left hand side of the window.
