Note: SW4 sets the I/O addresses for port1, SW 3 sets the I/O addresses for port 2, SW2 sets the I/O addresses for port 3, and SW1 sets the I/O addresses for port 4. A total of 128 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1-4/1 is the Most Significant Bit and switch SW1-4/7 is the Least Significant Bit. The switches have the following decimal values:SW1-4/1=1024, SW1-4/2=512, SW1-4/3=256, SW1-4/4=128, SW1-4/5=64, SW1-4/6=32, SW1-4/7=16. Turn off the switches and add the values of the switches to obtain the correct memory address. (On=0, Off=1) | |||||||
