2. Control Software Manual Set-up of evaluation board and control software
The control software packed with this evaluation board does not support I2C control. 1. Set up the AKD5365 according to previous term. 2. Connect IBM-AT compatible PC with the AKD5365 by 10-line type flat cable (packed with the AKD5365). Take care not to insert the 10pin header to the wrong direction. (This control software does not operate on Windows NT / 2000 / XP, therefore please operate it on Windows95 / 98 / Me.) 3. Insert the floppy-disk labeled "AKD5365 Control Program ver 1.0" into the floppy-disk drive. 4. Access the floppy-disk drive and double-click the icon of "akd5365.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 "Port Setup" button. 3. Click "Write default" button. 4. Then set up the dialog and input data.
Explanation of each buttons
1. Port Setup : 2. Write default : 3. Function1 : 4. Function2 : 5. Write : Set up the printer port. Initialize the register of AK5365. Dialog to write data by keyboard operation. Dialog to evaluate IPGA. Dialog to write data by mouse operation.
Explanation of each dialog
1. Function1 Dialog : Address Box: Data Box: Dialog to write data by keyboard operation
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 AK5365, click "OK" button. If not, click "Cancel" button.

2. Function2 Dialog :
Dialog to evaluate IPGA
Indication of data
Input data is indicated on the register map. Red letter means "H" or "1" and blue one means "L" or "0". Blank means the part that is not defined in the datasheet.
Attention on the operation
If you set up Function1 or Function2 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. If you click "Cancel" button during operation, the operation is cancelled and returns to the initial window.
