Control Software Manual Set-up of evaluation board and control software
1. Set up the AKD4345-A according to the Operating Sequence located on page 2. 2. Connect IBM-AT compatible PC with AKD4345-A by 10-line type flat cable (packed with AKD4345-A). 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 "AKD4345-A Evaluation Kit" into the CD-ROM drive. 4. Access the CD-ROM drive and double-click the icon of "akd4345-a.exe" to set up the control program. 5. Please evaluate according to the following.
