Control Soft Manual
■ Evaluation Board and Control Soft Settings
1. Set an evaluation board properly.
2. Connect the evaluation board to an IBM PC/AT compatible PC by a 10wire flat cable. Be aware of the direction of
the 10pin header. When running this control soft on the Windows 2000/XP, the driver which is included in the CD
must be installed. Refer to the “Driver Control Install Manual for AKM Device Control Software” for installing the
driver. When running this control soft on the windows 95/98/ME, driver installing is not necessary. This control soft
does not support the Windows NT.
3. Proceed evaluation by following the process below.
■ Operation Screen
1. Start up the control program following the process above.
The operation screen is shown below.

1. [REG]: Register Map
This tab is for a register writing and reading.
Each bit on the register map is a push-button switch.
Button Down indicates “H” or “1” and the bit name is in red (when read only it is in deep red).
Button Up indicates “L” or “0” and the bit name is in blue (when read only it is in gray)
Grayout registers are Read Only registers. They can not be controlled.
The registers which is not defined in the datasheet are indicated as “---”.
