Note: A total of 1023 memory base address settings are available. The switches are a binary representation of the decimal addresses. Switch 1 is the Least Significant Bit and switch 10 is the Most Significant Bit. The switches have the following decimal values: switch 1=1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128, 9=256, 10=512. Add the values of the off switches to obtain the correct memory address. (On=0, Off=1)
