| Note:A total of 64 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 SW1/6 is the Least |
| Significant Bit. The switches have the following |
| decimal values: SW1/1=512, SW1/2=256, SW1/3=128, |
| SW1/4=64, SW1/5=32, SW1/6=16. Turn off the switches |
| and add the values of the switches that are off to |
| obtain the correct address. (Off=1, On=0) |
