Evaluation Flow
<Initial Registration>
・Connect AKD7756-A-SUBboard with the USB box and then plug the USB with PC.
・Push the HOOK button of the evaluation unit for seven seconds, then the build-in Bluetooth becomes a stand-by
state.
・Turn mobile phone into Bluetooth search status. It might be displayed as [Free2move WA]. Please select it and
register it. Enter [0000] when password is required.
・Message of [Registration Finish] will be displayed.
・Registered machine will be searched and connected automatically when power on next time.
The flow of search will be different according to the mobile phone. (Ex. Password of mobile phone is possible to be
required) Please refer to the handling instruction manual of the mobile telephone for concerning details
<Call & Disconnection>
Accept Call: When Call occurs, push HOOK on front panel of this board.
CALL Setup: Please call setup by mobile phone and then push HOOK on the board.
Disconnect: Push HOOK on front panel

Control Software Manual
„ Setup of the evaluation board and control software
(1) Power AKD7756-A-SUB evaluation board on and connect with USB control box.
(2) Connect USB control box to PC with USB cable.
The usb control box is recognized as HID (Human Interface Device). When it can not be recognized correctly
(e.g., unknown device is connected), please push reset button [yellow] on USB control box.
(3) Install AK7756.exe in your PC. Then ready to evaluate.
(4) When Bluetooth is used, connect mobile telephone with Bluetooth Transceiver. Please refer to the evaluation flow
of above-mentioned Bluetooth mode.
The start-up image of control software is as below.
Figure 4. Start-up Image of Control Software
Whenever USB control box is unplugged from PC; must run the control software again.
