2) Set up the jumper pins and connectors. (According to explanations of ‘Evaluation mode’: P.4 to P.6)
3) USB Connect
Connect the board to PC with the USB cable packed.
It is required to push down the button ‘SW1’ to initialize PIC18F4550, the control device from PC.
4) Power on
Power the board on and start up the AK7600 control software.
5) Setup the control register (According to explanations of ‘Control Software Manual’: P.8 to P.22)
Click the button, ‘Board Init’ on the AK7600 software to initialize.
* When the power is down, DZF pin is off.
„ Evaluation Mode
(When you use a sub-board, the silk print numbers on the board of jumpers are changed
from the main board JP9 to the sub-board JP1A and the main board JP19 to the sub-board JP2A.)


This evaluation mode is for analog inputs and analog outputs by passing internal ADC and DAC.
