       Note:The address range for the QS-100D is from 0 to FFFFh. The
       switches are a binary representation of the addresses. The
       switches have the following decimal values: SW1/1=8, SW1/2=4,
       SW1/3=2, SW1/4=1, SW1/5=8, SW1/6=4, SW2/1=2, SW2/2=8, SW2/3=4,
       SW2/4=2, SW2/5=1.
