                        BASE I/O ADDRESS SELECTION

    Note:      A total of 32 base address settings are available. The
               switches are a binary representation of the decimal memory
               addresses. SW1/1 is the Most Significant Bit and switch
               SW1/5 is the Least Significant Bit. The switches decimal
               values are unidentified. (Off=1, On=0)
