Note: A total of 255 memory base address settings are available. The switches are a binary representation of the decimal addresses. Switch 8 is the Least Significant Bit and switch 1 is the Most Significant Bit. The switches have the following decimal values: switch 8=1, 7=2, 6=4, 5=8, 4=16, 3=32, 2=64, 1=128. Turn off the switches and add the off switches to obtain the correct memory base address. (On=0, Off=1) | ||||||||
