Note: A total of 128 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/7 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/7=512, SW1/6=256, SW1/5=128, SW1/4=64, SW1/3=32, SW1/2=16, SW1/1=8. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0)SW1 sets the address for port 1. The settings for SW2 through SW4 are identical and set the addresses for ports 2 through 4, respectively. |
