Note: A total of 255 base address settings are available. The switches are a binary representation of the decimal memory addresses. S1/A9 is the Most Significant Bit and switch S1/A2 is the Least Significant Bit. The switches have the following decimal values: S1/A9=512, S1/A8=256, S1/A7=128, S1/A6=64, S1/A5=32, S1/A4=16, S1/A3=8, S1/A2=4. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0) |
