Note:

A total of 255 base address settings are available. The switches are a binary representation of the decimal memory addresses. S1/A10 is the Most Significant Bit and switch S1/A3 is the Least Significant Bit. The switches have the following decimal values: S1/A10=1024, S1/A9=512, S1/A8=256, S1/A7=128, S1/A6=64, S1/A5=32, S1/A4=16, S1/A3=8. In addition, a base value of 7 must be added to all decimal values to account for fixed bits A2, A1, and A0. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0)
