Next, set the controller’s Base I/O Port address with the W2 and W3 jumpers. W3
selects the high-order address, and W2 th 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 E281-4035 is 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.
