The I/O port address is a hexadecimal number and must be any multiple of
020h within the range of 060h to 03C0h. The hexadecimal address is then
converted into binary code so the DIP switches can be set to the “1”
position (OFF) or to the “0” position (ON). The most commonly used
I/O addresses are listed in the following table.
Note: The recommended I/O port address is 300h. Other I/O ports may be set on
the card. If you are unable to determine the DIP switch settings for the
desired I/O port, contact EXFO.
