28 PCI-1710/1710HG User's Manual

4.1 Overview

The PCI-1710/1710HG is delivered with an easy-to-use 32-bit DLL

driver for user programming under the Windows 95/NT operating

system. We advise users to program the PCI-1710/1710HG 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-1710/

1710HG card at a 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.

4.2 I/O Port Address Map

The PCI-1710/1710HG card 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.

Table 4-1 shows the function of each register or driver and its address

relative to the card’s base address.
