Usage

• Use FA-124 software to copy the Add-in to your calculator.

• Use the LINK app in calcutor menu to connect the calculator to your computer.

• READ NOTICE BEFORE THIS STEP! Download Zadig from here. Open Zadig, click Options - List All Device, select CESG502, and replace the original driver with WinUSB.

• Open the Add-in in your calculator. It will automatically connect to your computer. If you didn't plug the USB cable, it will exit after a short time.

• Open the fxKeyboardLink software in your computer. Now you can use your calculator as a keyboard for your computer.

• Some special keyboard mapping:

Notice

• This tool will automatically open the NumLock in your computer.
• Once your use Zadig to replace the original driver, you can't use FA-124 to link your calculater. If you want to get back to the original driver, follow Zadig's FAQ here carefully. You need to know that the USB device is CESG502.
• If you can't connect your calculator to your computer in any way, try to restart your calculator by the button behind.

Known Issue

• Press the calculator key down continously will not work like that in your computer. The reason is that I only used GetKey function in this Add-in.
• In cursor mode, the cursor moved slowly in a constant speed.
• I would be glad if someone can fix the issues above.

Thanks
