Base address setting (SW1 or S2)
For base address specify the I/O address of the first port and subsequent
ports are set continuous base addresses by the offset of 8 bytes. For
instance, if the first port is set for 300H, then the second port is set to
308H sequentially. For 8 ports, specify the continuous PORT number of
the first port and subsequent ports are mapped to continuous PORT num-
bers. For example:
Select an address, which is not already in use by another card in the sys-
tem. If you are installing more than one card in your system, set the card
to different base address. DIP switch (SW1) controls each card’s base
address, as shown below.
