Connecting the WiFiHU2 or WiFiHU2-NE to Your System

rior to connecting the WiFiHU2 to a Window XP, the drivers should be installed. The

iFiHU2 Modules are designed for easy connection to any standard USB Port and

W wireless network. Connect one end of the USB cable into the USB connector on the WiFiHU2-NE and the other into any available USB receptacle on your computer. The WiFiHU2-NE’s “Hot Swap-able” interface allows you to plug or unplug the module when the computer is on. If using Windows, load the provided drivers. The WiFiHU2-N is now ready for use.

If you plan to embed the WiFiHU2 into your system, the initial evaluation consists of the

iFiHU2 USB Module mW WiFiHU2 carefully remove it from the two 8 pin headers on the WiFiHU2-NE USB interface board. Save this interface board. The WiFiHU2 can always be reinstalled into the WiFiHU2-NE USB interface board and connected to any standard USB port to verif or test the module functions.

If you use external antenna, connect one end of Radicom approved antenna to the on
