Note: A total of 127 memory address settings are available. The switches are a binary representation of the hexadecimal memory addresses. SW1/7 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following hexadecimal values: SW1/6=200h, SW1/5=100h, SW1/4=80h, SW1/3=40h, SW1/2=20h, SW1/1=10h. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0) | |||||||
