This chapter describes the PCI-DIO-96, PXI-6508, and PCI-6503; lists
what you need to get started, software programming choices, and optional
equipment; describes custom cabling options; and explains how to unpack
your board.
Thank you for purchasing a National Instruments PCI-DIO-96, PXI-6508,
or PCI-6503 board. The PCI-DIO-96 is a 96-bit, parallel, digital I/O
interface for PCI bus computers. The PXI-6508 is a 96-bit, parallel, digital
I/O interface for PXI and CompactPCI chassis. The PCI-6503 is a 24-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 on the PCI-DIO-96 or PXI-6508. On
the PCI-6503, one 82C55A PPI controls the 24 bits of TTL-compatible
digital I/O. The 82C55A PPI chips can operate in unidirectional mode,
bidirectional mode, or handshaking mode and can generate interrupt
requests to your computer. The digital I/O lines are all accessible through a
100-pin female connector on the PCI-DIO-96 or PXI-6508 and a 50-pin
male connector on the PCI-6503.
Your DIO board 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.
With your DIO board, 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, PXI-6508, and PCI-6503 specifications are in
Appendix A, Specifications.
