Note:The address range for the PC-02 is from 0 to 3FCh. The switches are a binary representation of the addresses, increasing in weight from left to right. When a switch is off, the corresponding bit is set to 1 and has the following decimal value: SW1/1=4, SW1/2=8, SW1/3=1, SW1/4=2, SW1/5=4, SW1/6=8, SW1/7=1, SW1/8=2. | |||||||||
