| 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. |
