Register Structure and Format
C.1 Overview
The PCI-1711/1731 is delivered with an easy-to-use 32-bit DLL
driver for user programming under the Windows 95/98/NT operating
system. We advise users to program the PCI-1711/1731 using the 32-
bit DLL driver provided by Advantech to avoid the complexity of
low-level programming by register.
The most important consideration in programming the PCI-1711/
1731 at the register level is to understand the function of the card's
registers. The information in the following sections is provided only
for users who would like to do their own low-level programming.
C.2 I/O Port Address Map
The PCI-1711/1731 requires 32 consecutive addresses in the PC's I/O
space. The address of each register is specified as an offset from the
card's base address. For example, BASE+0 is the card's base address
and BASE+7 is the base address plus seven bytes.
The table C-1 shows the function of each register or driver and its
address relative to the card's base address.
