| Note: |
| |
|A total of 255 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 |
|SW1/8 is the Least Significant Bit. The switches have the |
|following decimal values: SW1/1=256, SW1/2=128, SW1/3=64, |
|SW1/4=32, SW1/5=16, SW1/6=8, SW1/7=4. Turn off the switches |
|and add the values of the switches, including an additional |
|value of 512 as a fixed setting, to obtain the correct |
|memory address. (Off=1, On=0) |

| the switches to another 37-pin connector (Port B). |
