Introduction
This chapter describes the PCI-MIO E Series boards, lists what you
need to get started, describes the optional software and optional
equipment, and explains how to unpack your PCI-MIO E Series board.
About the PCI-MIO E Series
Thank you for buying a National Instruments PCI-MIO E Series board.
The PCI-MIO E Series boards are completely Plug and Play,
multifunction analog, digital, and timing I/O boards for PCI bus
computers. This family of boards features 12-bit and 16-bit ADCs with
16 analog inputs, 12-bit and 16-bit DACs with voltage outputs, eight
lines of TTL-compatible digital I/O, and two 24-bit counter/timers for
timing I/O. Because the PCI-MIO E Series boards have no DIP
switches, jumpers, or potentiometers, they are easily software-
configured and calibrated.
The PCI-MIO E Series boards are completely switchless and jumperless
data acquisition (DAQ) boards for the PCI bus. This feature is made
possible by the National Instruments MITE bus interface chip that
connects the board to the PCI I/O bus. The MITE implements the PCI
Local Bus Specification so that the interrupts and base memory
addresses are all software configured.
The PCI-MIO E Series boards use the National Instruments DAQ-STC
system timing controller for time-related functions. The DAQ-STC
consists of three timing groups that control analog input, analog output,
and general-purpose counter/timer functions. These groups include a
total of seven 24-bit and three 16-bit counters and a maximum timing
resolution of 50 ns. The DAQ-STC makes possible such applications as
buffered pulse generation, equivalent time sampling, and seamlessly
changing the sampling rate.
Often with DAQ boards, you cannot easily synchronize several
measurement functions to a common trigger or timing event. The
PCI-MIO E Series boards have the Real-Time System Integration
(RTSI) bus to solve this problem. The RTSI bus consists of our RTSI

Chapter 1 Introduction
PCI-MIO E Series User Manual 1-2 © National Instruments Corporation
bus interface and a ribbon cable to route timing and trigger signals
between several functions on as many as five DAQ boards in your
computer.
The PCI-MIO E Series boards can interface to an SCXI system so that
you can acquire over 3,000 analog signals from thermocouples, RTDs,
strain gauges, voltage sources, and current sources. You can also
acquire or generate digital signals for communication and control.
SCXI is the instrumentation front end for plug-in DAQ boards.
Detailed specifications of the PCI-MIO E Series boards are in
Appendix A, Specifications.

Software Programming Choices
You have several options to choose from when programming your
National Instruments DAQ and SCXI hardware. You can use National
Instruments application software, NI-DAQ, or register-level
programming.
National Instruments Application Software
ComponentWorks contains tools for data acquisition and instrument
control built on NI-DAQ driver software. ComponentWorks provides a
higher-level programming interface for building virtual instruments
through standard OLE controls and DLLs. With ComponentWorks, you
can use all of the configuration tools, resource management utilities,
and interactive control utilities included with NI-DAQ.
LabVIEW features interactive graphics, a state-of-the-art user
interface, and a powerful graphical programming language. The
LabVIEW Data Acquisition VI Library, a series of VIs for using
LabVIEW with National Instruments DAQ hardware, is included with
LabVIEW. The LabVIEW Data Acquisition VI Library is functionally
equivalent to NI-DAQ software.
LabWindows/CVI features interactive graphics, state-of-the-art user
interface, and uses the ANSI standard C programming language. The
LabWindows/CVI Data Acquisition Library, a series of functions for
using LabWindows/CVI with National Instruments DAQ hardware, is
included with the NI-DAQ software kit. The LabWindows/CVI Data
Acquisition Library is functionally equivalent to the NI-DAQ software.
VirtualBench features virtual instruments that combine DAQ products,
software, and your computer to create a stand-alone instrument with the
added benefit of the processing, display, and storage capabilities of
your computer. VirtualBench instruments load and save waveform data
to disk in the same forms that can be used in popular spreadsheet
programs and word processors.
Using ComponentWorks, LabVIEW, LabWindows/CVI, or
VirtualBench software will greatly reduce the development time for
your data acquisition and control application.

Chapter 1 Introduction
PCI-MIO E Series User Manual 1-4 © National Instruments Corporation
NI-DAQ Driver Software
The NI-DAQ driver software is included at no charge with all National
Instruments DAQ hardware. NI-DAQ is not packaged with SCXI or
accessory products, except for the SCXI-1200. 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
(timed D/A conversion), digital I/O, counter/timer operations, SCXI,
RTSI, self-calibration, messaging, and acquiring data to extended
memory.
NI-DAQ has both high-level DAQ I/O functions for maximum ease of
use and low-level DAQ I/O functions for maximum flexibility and
performance. Examples of high-level functions are streaming data to
disk or acquiring a certain number of data points. An example of a
low-level function is writing directly to registers on the DAQ device.
NI-DAQ does not sacrifice the performance of National Instruments
DAQ devices because it lets multiple devices operate at their peak.
NI-DAQ also internally addresses many of the complex issues between
the computer and the DAQ hardware such as programming interrupts
and DMA controllers. NI-DAQ maintains a consistent software
interface among its different versions so that you can change platforms
with minimal modifications to your code. Whether you are using
conventional programming languages or National Instruments
application software, your application uses the NI-DAQ driver
software, as illustrated in Figure 1-1.

NI-DAQ, and Your Hardware
Register-Level Programming
The final option for programming any National Instruments DAQ
hardware is to write register-level software. Writing register-level
programming software can be very time-consuming and inefficient, and

Even if you are an experienced register-level programmer, using
NI-DAQ or application software to program your National Instruments
DAQ hardware is easier than, and as flexible as, register-level
programming, and can save weeks of development time.

Custom Cabling
National Instruments offers cables and accessories for you to prototype
your application or to use if you frequently change board
interconnections.
If you want to develop your own cable, however, the following
guidelines may be useful:
• For the analog input signals, shielded twisted-pair wires for each
analog input pair yield the best results, assuming that you use
differential inputs. Tie the shield for each signal pair to the ground
reference at the source.
• You should route the analog lines separately from the digital lines.
• When using a cable shield, use separate shields for the analog and
digital halves of the cable. Failure to do so results in noise coupling
into the analog signals from transient digital signals.
The following list gives recommended part numbers for connectors that
mate to the I/O connector on your PCI-MIO E Series board.
