Next, set the controller’s Base I/O Port address with the W2 and W3 jumpers. W3
selects the high-order address, and W2 the low-order address. The values of the
settings are shown in the following table:

To calculate the Base I/O Port address, add the values of the jumpered positions of
W3 and W2. For example, the E281{A}-4025 is usually shipped jumpered for a
Base I/O Port address of 280 hexadecimal. W3 is jumpered in the third position
(200), and W2 is jumpered in the fifth position (80). The address is the sum of
200 + 80, which is 280.
