Introduction
This chapter lists what you need to get started, provides an overview of the
PXI hardware and the NI-CAN software for Windows NT, and describes
optional equipment you can order.
What You Need to Get Started
Make sure you have all of the following items before you attempt to install
the hardware and software:
❑ Windows NT 3.51 or later installed on your computer
– PXI-8461 one port
– PXI-8461 two port
– PXI-8460 one port
– PXI-8460 two port
❑ 3.5 in., high-density (1.44 MB) disks, which are included in your kit:
– NI-CAN Software for Windows 95/98/NT
Version 1.3
(Disk x of 3)
❑ CAN interface cables that meet the requirements in Appendix B,
Cabling Requirements for PXI-8461 High-Speed CAN or Appendix C,
Cabling Requirements for PXI-8460 Low-Speed CAN.
Hardware Overview
The PXI-8461 and PXI-8460 (one port and two port) are software
configurable and compliant with the PXI Specification and CompactPCI
Specification. With a PXI-8461 or PXI-8460 board, you can make your
PXI or CompactPCI chassis communicate with and control CAN devices.
The PXI-8461 physical layer fully conforms to the ISO 11898
physical layer specification for CAN and is optically isolated to 500 V.
The PXI-8460 physical layer conforms to the ISO 11519-2 physical layer
