4-3-8 DIP Switch Circuit
The key board circuit consist of the scan signal of 3 lines and the return signal of 2-line. The CPU sends
repeatedly and continuously the scan data DIP_A~DIP. The DIP S/W information input in the return signal if
the specific DIP S/W is ON status during the given time. The CPU reads the data through DIP IN1~IN2 and
analyzes what DIP S/W is ON and performs the selected function.
