Control Software Manual Set-up of evaluation board and control software
1. Set up the AKD4114-B according to previous term. 2. Connect IBM-AT compatible PC with AKD4114-B by 10-line type flat cable (packed with AKD4114-B). Take care of the direction of 10pin header. (Please install the driver in the CD-ROM when this control software is used on Windows 2000 / XP. Please refer "Installation Manual of Control Software Driver by AKM device control software". In case of Windows95 / 98 / ME, this installation is not needed. This control software does not operate on Windows NT.) 3. Insert the CD-ROM labeled "AKD4114-B Evaluation Kit" into the CD-ROM drive. 4. Access the CD-ROM drive and double-click the icon of "akd4114-b0.exe" to set up the control program. 5. Then please evaluate according to the follows.
Operation flow
Keep the following flow. 1. Set up the control program according to explanation above. 2. Click "Write default" button. 3. Then set up the dialog and input data.

Explanation of each dialog
1. Function1 Dialog : Dialog to write data by keyboard operation Address Box: Data Box: Input register address in 2 figures of hexadecimal. Input register data in 2 figures of hexadecimal.
If you want to write the input data to AK4114, click "OK" button. If not, click "Cancel" button. 2. Write Dialog : Dialog to write data by mouse operation There are dialogs corresponding to each register. Click the "Write" button corresponding to each register to set up the dialog. If you check the check box, data becomes "H" or "1". If not, "L" or "0". If you want to write the input data to AK4114, click "OK" button. If not, click "Cancel" button.
Indication of data
Input data is indicated on the register map. Red letter indicates "H" or "1" and blue one indicates "L" or "0". Blank is the part that is not defined in the datasheet.
Attention on the operation
If you set up Function1 dialog, input data to all boxes. Attention dialog is indicated if you input data or address that is not specified in the datasheet or you click "OK" button before you input data. In that case set up the dialog and input data once more again. These operations does not need if you click "Cancel" button or check the check box.
