   |   Note: The address range for the DMM-100 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, SW1/7=2, SW1/8=1, SW2/1=8, SW2/2=4, SW2/3=2,    |
   |   SW2/4=1, SW2/5=8, SW2/6=4. The DMM-100 requires four     |
   |   consecutive address locations.                           |
