Note: A total of 256 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. SW1/1 is the Most Significant Bit and jumper SW1/8 is the Least Significant Bit. The jumpers have the following decimal values: SW1/1=4096, SW1/2=2048, SW1/3=1024, SW1/4=512, SW1/5=256, SW1/6=128, SW1/7=64, SW1/8=32. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0) | ||||||||
