| Note: A total of 32 base address settings are available. The switches are a binary representation of the hexadecimal memory addresses. SW1/7 is the Most Significant Bit and switch SW1/3 is the Least Significant Bit. The switches have the following hexadecimal values: SW1/7=4000h, SW1/6=2000h, SW1/5=1000h, SW1/4=800h, SW1/3=400h. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0) | ||||||
