This chapter describes the PCI-DIO-96; lists what you need to get
started, software programming choices, optional equipment; describes
custom cabling options; and explains how to unpack the PCI-DIO-96.
About the PCI-DIO-96
Thank you for purchasing a National Instruments PCI-DIO-96 board.
The PCI-DIO-96 is a 96-bit, parallel, digital I/O interface for PCI bus
computers. Four 82C55A programmable peripheral interface (PPI)
chips control the 96 bits of TTL-compatible digital I/O. The four OKI
Semiconductor 82C55A PPI chips can operate in unidirectional mode,
bidirectional mode, or handshaking mode and can generate interrupt
requests to your computer. You can program the 82C55A for almost any
8-bit or 16-bit digital I/O application. The OKI Semiconductor 82C53
counter/timer chip has two usable counters that can generate timed
interrupt requests to your computer. The digital I/O lines are all
accessible through a 100-pin female connector.
The PCI-DIO-96 is a completely switchless and jumperless DAQ board.
All resource allocation is completed automatically at startup, so you
will not need to set interrupt levels or base addresses for the
PCI-DIO-96.
You can use the PCI-DIO-96 in a wide range of digital I/O applications.
For example, you can connect the PCI-DIO-96 to any of the following:
panel meters, instruments and test equipment with BCD readouts and/or
controls, or optically isolated, solid-state relays and I/O module
mounting racks.
With the PCI-DIO-96, you can use your computer as a digital I/O
system controller for laboratory testing, production testing, and
industrial process monitoring and control.
Detailed PCI-DIO-96 specifications are in Appendix A, Specifications.
