| | Note (1): The address range for the SCB-1040/1050 is |
| | from 0 to 3F8h. The switches are a binary |
| | representation of the addresses. When a switch is |
| | off, the corresponding bit is set to 1 and has the |
| | following decimal value: SW1/1=2, SW1/2=1, SW1/3=8, |
| | SW1/4=4, SW1/5=2, SW1/6=1, SW1/7=8. SW1/8 is not |
| | used and the factory setting should not be altered. |
| | The SCB-1040/1050 requires 8 consecutive address |
| | locations. |
