Note:

A total of 30 address settings are available. The switches are a binary representation of the hexadecimal memory addresses. SW1/1 is the Most Significant Bit and SW1/5 is the Least Significant Bit. The switches have the following hexadecimal values: SW1/5=01h, SW1/4=02h, SW1/3=04h, SW1/2=08h, SW1/1=10h. Turn on the switches and add the values of the switches to obtain the correct memory address. (Off=0, On=1)
