software tools, the National Instruments LabVIEW and LabWindows/CVI
application software, and the NI-VISA, NI-488.2M, and NI-DAQ software.
Hardware Description
Benefits of PXI
The PXI-8150B Series PXI/CompactPCI embedded computers are
high-performance CompactPCI-compatible system controllers that are
compatible with the PXI bus specification. PXI defines a compact modular
PC platform for industrial instrumentation. PXI leverages the PCI bus,
which is the de facto standard for today’s desktop computer software and
hardware designs. As a result, PXI users receive all the benefits of PCI
within an architecture that supports mechanical, electrical, and software
features tailored to industrial instrumentation, data acquisition, and
automation applications.
Well-suited for industrial applications, PXI leverages from the
CompactPCI specification, which defines a rugged form factor for PCI that
offers superior mechanical integrity and easy installation and removal of
hardware components. PXI products offer higher and more carefully
defined levels of environmental perfo rmance required by the vibration,
shock, temperature, and humidity extremes of industrial environments.
PXI adds mandatory environmental testing and active cooling to the
CompactPCI mechanical specification to ease system integration and
ensure multivendor interoperability.
Chapter 1 Introduction
Additionally, PXI meets the more specific needs of instrumentation users
by adding an integrated trigger bus and reference clock for multiple-board
synchronization, a star trigger bus for very precise timing, and local buses
for side-band communication between adjacent peripherals.
PXI-8150B Series Design
The PXI-8150B Series PXI embedded computers are high-performance
PXI system controllers with all the standard I/O features built in. The
PXI-8150B Series uses state-of-the-art technology and packaging to create
a fully PC-compatible controller for PXI. Due to the unique design and
packaging, these computers have onboard PCI video and are still able to
connect to the PXI bus without the need of a PCI-to-PCI bridge. As a result,
they preserve the full 132 Mbytes/s PCI bandwid th for other PXI boards. In
addition, the PXI-8150B supports masters in all seven available PXI slots.

National Instruments Corporation 1-3 PXI-8150B Series User Manual
Chapter 1 Introduction
The PXI-8150B Series design includes many standard PC peripherals,
which means you can install your custom-designed peripheral devices in all
PXI slots. It also has two user-accessible SO-DIMM sockets so it is easy to
upgrade memory. The unique packaging includes a built-in 1.44 MB floppy
drive and 2.5 in. hard drive. The mechanical assembly of the PXI-8150B
mounts these devices to the PXI-8150B main board so you can remove the
entire unit intact. This eases integration issues and cabling. The PXI-8150B
plugs directly into the system controller slot and expands to the left, thus
preserving all usable PXI slots for user-defined peripheral devices.
PXI-8150B Series Models
Currently the PXI-8150B Series consists of two models—the PXI-8155B
and the PXI-8156B. Both models have two CPU choices—a 233 MHz or
333 MHz MMX processor.
The models differ in the front-panel I/O. The PXI-8155B comes complete
with a 3.5 in. 1.44 MB floppy drive, 4 GB hard dri ve or larger, Super VGA
with 2 MB SGRAM, a serial port, an IEEE 1284 parallel port, a PS/2
keyboard and mouse, a USB connector, and software installed. The
PXI-8156B adds a second serial port, a 10BaseT Ethernet port, and an
IEEE 488.2 (GPIB) interface compatible with the National Instruments
AT-GPIB/TNT.
Memory
The PXI-8150B and its memory sockets are easily accessible so you can
install additional DRAM in the field. You can install up to 256 MB of
10 ns SDRAM, using 144-pin SO-DIMMS.
The PXI-8150B contains at least a 4 GB internal, enhanced IDE hard disk.
For information on adding RAM by installing SO-DIMMs, refer to
Appendix A, Specifications.
System Slot Functionality
You can use the PXI-8150B Series computers to achieve full PXI system
slot control of your PXI system. In the system slot, the PXI-8150B provides
master/slave capabilities to all slots in the PXI system.

Chapter 1 Introduction
Any GPIB application using NI-488.2M or NI-VISA will run on the
PXI-8156B.
NI-DAQ has an extensive library of functions that you can call from your
application programming environment. These functions include routines
for analog input (A/D conversion), buffered data acquisition (high-speed
A/D conversion), analog output (D/A conversion), waveform generation,
digital I/O, counter/timer operations, SCXI, RTSI, self-calibration,
messaging, and acquiring data to extended memory.
NI-VISA is the National Instruments implementation of the VISA
specification. VISA is a uniform API for communicating and controlling
Serial, GPIB, PXI, VXI, and various other types of instruments. This API
aids in the creation of more portable applications and instrument drivers.
For information on writing your own PXI instrument driver with NI-VISA,
see the NI-VISA Getting Started manual and the
NI-VISA directory.

You can also use the National Instruments LabVIEW and
LabWindows/CVI application programs and instrument drivers to ease
your programming task. These standardized programs match the modular
virtual instrument capability of PXI and can reduce your PXI software
development time. These programs feature extensive libraries of GPIB,
Serial, and VXI instrument drivers written to take full advantage of direct
PXI control. LabVIEW and LabWindo ws/CVI include all the tools needed
for instrument control, data acquisition, analysis, and presentation.
LabVIEW is a complete programming environment that departs from the
sequential nature of traditional programming languages and features a
graphical programming environment.
LabWindows/CVI is an interactive C development environment for
building test and measurement and instrument control systems. It includes
interactive code-generation tools and a graphical editor for b uilding custom
user interfaces.
