PCIe-DIO-24HS - Acces I/O Products, Inc.

This product is a x1 lane PCI Express digital I/O board available in two models. The PCIe-DIO-24H is the basic DIO and the PCI-DIO-24HS features advanced change-of-state (COS) detection capabilities. The card emulates an 8255 compatible chip, providing 24 DIO lines. The DIO lines are grouped into three 8-bit ports: A, B, and C. Each 8-bit port is configured via software to function as either inputs or outputs. Port C can be further broken into two 4-bit nybbles via software and configured as either inputs or outputs.
