Connecting the WiFiHU2 or WiFiHU2-NE to Your System
Prior to connecting the WiFiHU2 to a Window XP, the drivers should be installed. The
WiFiHU2 Modules are designed for easy connection to any standard USB Port and
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 even
when the computer is on. If using Windows, load the provided drivers. The WiFiHU2-NE
is now ready for use.
If you plan to embed the WiFiHU2 into your system, the initial evaluation consists of the
WiFiHU2 USB Module mounted onto a USB hub PCB (WiFiHU2-NE). To remove the
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 verify
or test the module functions.
If you use external antenna, connect one end of Radicom approved antenna to the on
board socket. For ultimate performance, we recommend using two antennas to meet MIMO
requirement with exceptional reception and throughput. If only using one antenna, you must
use the correct antenna socket for good performance. Connect single antenna to the socket closest
to the Radicom Research white silkscreen legend on the PCB.
