Note: A total of 32 base address settings are available. The switches are a binary representation of the decimal memory addresses. JP5 is the Most Significant Bit and switch SW1/3 is the Least Significant Bit. The switches have the following decimal values: JP5=131072 JP6=65536, SW1/1=32768, SW1/2=16384, SW1/3=8192. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0) | ||||||
