NI PXI-6508 PCI-6503 board

Description

NI PXI-6508 PCI-6503 board

PPI x, where the x is replaced by A, B, C, or D, refers to one of the four programmable peripheral interface (PPI) chips on the PCI-DIO-96 or PXI-6508. The PCI-6503 contains only one PPI, PPI A.

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.

To set up and use your PCI-DIO-96/PXI-6508/PCI-6503 board, you will need the following:
❑ PCI-DIO-96, PXI-6508, or PCI-6503 board
❑ PCI-DIO-96/PXI-6508/PCI-6503 User Manual
❑ One of the following software packages and documentation:
– LabVIEW
– LabWindows/CVI
– NI-DAQmx
– Traditional NI-DAQ (Legacy)
– Measurement Studio
❑ Your computer, or PXI or CompactPCI chassis and controller

The mating connector for the PCI-6503 is a 50-position, polarized ribbon socket connector with strain relief. National Instruments uses a polarized (keyed) connector to prevent inadvertent upside-down connections. Recommended manufacturer part numbers for this mating connector are as follows:

• Electronic Products Division/3M (part number 3425-7650)

• T&B/Ansley Corporation (part number 622-5041)
