Connecting the WiFiHU or WiFiHU-NE to Your System

The WiFiHU 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 WiFiHU-NE and the other into any available USB receptacle on your computer. The WiFiHU-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 WiFiHU-NE is now ready for use.

If you plan to embed the WiFiHU into your system, the initial evaluation consists of the WiFiHU USB Module mounted onto a USB hub PCB (WiFiHU-NE). To remove the WiFiHU carefully remove it from the two 8 pin headers on the WiFiHU-NE USB interface board. Save this interface board. The WiFiHU can always be reinstalled into the WiFiHU-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.

Mechanical Specification and Pin Orientation for the WiFiHU

The WiFiHU USB Half Inch Modules are designed for easy connection to any standard USB interface and wireless network. The connection is made through two 8-pin headers, which may be attached to your device via a socket or by individually hardwiring each pin.

Notes:

1. Pin Spacing is 0.100 inch from center to center

2. Dimension of the WiFiHU module – 1.10 x 1.00 x 0.25 inch

3. Suggested mating female connector: Samtec P/N. #SSW-110-21-G-S (RoHS Thru-Hole)

Samtec P/N. #SSW-110-22-G-S-VS (RoHS SMT)

4. Square pins – 0.025 x 0.025 inch
