2. Setting ISA Card Address
Each ISA I/O card installed in a PC uses one or more I/O address
locations within your computer's I/O address space. These address
locations are used by software running on the PC's processor in
communicating with electronics on the card.
In order to not interfere with other installed cards in the PC, each
card must use unique addresses. The interface card address
determines the card's location within your computer's I/O address
space.
Certain I/O addresses are used by the PC, others are free and may be
used by the interface card. Refer to the manual that accompanied
your PC for information regarding available address location in your
PC.
The CIO-DIO24 ISA interface card uses 4 consecutive addresses
starting with the base address selected with the ADDRESS switch
on interface card . The factory default setting for the interface card
is 300H. We recommend the default factory setting be tried first.
The ADDRESS switch may be set for addresses in the range of
000H to 3FCH. It should not be hard to find a free address area for
the card in your PC. Addresses 300H to 31FH are is a prototype
card area, and is often available for add-in cards. Addresses 390H to
39F may also be available.
The InstaCal software provides a graphical representation of
ADDRESS switch settings. We recommend that you install and run
InstaCal software before installing the interface card in your PC.
