Introduction
This chapter describes the 6034E and 6035E devices, lists what you need
to get started, gives unpacking instructions, and describes the optional
software and equipment.
Features of the 6034E and 6035E
Thank you for buying a National Instruments 6034E or 6035E device. The
6035E features 16 channels (eight differential) of 16-bit analog input,
two channels of 12-bit analog output, a 68-pin connector, and eight lines of
digital I/O. The 6034E is identical to the 6035E, except that it does not have
analog output channels.
These devices 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 seamless changing of the sampling rate.
1
With other DAQ devices, you cannot easily synchronize several
measurement functions to a common trigger or timing event. These devices
have the Real-Time System Integration (RTSI) bus to solve this problem.
In a PCI system, the RTSI bus consists of the National Instruments RTSI
bus interface and a ribbon cable to route timing and trigger signals between
several functions on as many as five DAQ devices in your computer. In a
PXI system, the RTSI bus consists of the National Instruments RTSI bus
interface and the PXI trigger signals on the PXI backplane to route timing
and trigger signals between several functions on as many as seven DAQ
devices in your system.
These devices can interface to an SCXI system—the instrumentation front
end for plug-in DA Q de vices—so that you can acquire analog signals from
thermocouples, RT Ds, strain g auges, v oltage sources, and current sources.
You can also acquire or generate digital signals for communication and
control.
Using PXI compatible products with standard CompactPCI products is an
important feature provided by PXI Specification, Revision 1.0. If you use a
PXI compatible plug-in card in a standard CompactPCI chassis, you will be
unable to use PXI-specific functions, but you can still use the basic plug-in
card functions. For example, the RTSI bus on your PXI E Series device is
available in a PXI chassis, but not in a CompactPCI chassis.
The CompactPCI specification permits vendors to develop sub-buses that
coexist with the basic PCI interface on the CompactPCI bus. Compatible
operation is not guaranteed between CompactPCI devices with different
sub-buses nor between CompactPCI devices with sub-buses and PXI.
The standard implementation for CompactPCI does not include these
sub-buses. Your PXI E Series device will work in any standard
CompactPCI chassis adhering to PICMG CompactPCI 2.0 R2.1 core
specification.
PXI specific features are implemented on the J2 connector of the
CompactPCI bus. Table 3-3 lists the J2 pins used by your PXI E Series
device. Your PXI device is compatible with any Compact PCI chassis with
a sub-bus that does not drive these lines. Even if the sub-bus is capable of
driving these lines, the PXI device is still compatible as long as those pins
on the sub-bus are disabled by default and not ever enabled. Damage may
result if these lines are driven by the sub-bus.

Chapter 1Introduction
•Measure
•NI-DAQ for PC Compatibles
•VirtualBench
❑ Your computer equipped with one of the following:
•PCI bus for a PCI device
•PXI or CompactPCI chassis and controller for a PXI device
Your device is shipped in an antistatic package to prevent electrostatic
damage to the device. Electrostatic discharge can damage several
components on the device. To avoid such damage in handling the device,
take the following precautions:
•Ground yourself via a grounding strap or b y holding a grounded object.
•Touch the antistatic package to a metal part of your computer chassis
before removing the device from the package.
•Remove the device from the package and inspect the device for
loose components or any other sign of damage. Notify National
Instruments if the device appears damaged in any way. Do not install
a damaged device into your computer.
•Never touch the exposed pins of connectors.
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 soft ware 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 cap a bilities 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.
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.
6034E/6035E User Manual1-4www.natinst.com
Chapter 1Introduction
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.

Installation and Configuration
This chapter explains how to install and configure your 6034E or 6035E.
Software Installation
2
Caution
You should install your software before you install your device.
If you are using LabVIEW, LabWindows/CVI, other National Instruments
application software packages, or the NI-DAQ driver software, refer to the
appropriate release notes. After you have installed your application
software, refer to your NI-DAQ release notes and follow the instructions
given there for your operating system and application software package.
If you are a register-level programmer, refer to the PCI E Series
Register-Level Programmer Manual and the DAQ-STC Technical
Reference Manual for software configuration information.
Hardware Installation
Note
Install your software before you install your device.
After installing your software, you are ready to install your hardware. Your
device will fit in any 5 V expansion slot in your computer. However, to
achieve best noise performance, leave as much room as possible between
your device and other devices. The following are general installation
instructions. Consult your computer user manual or technical reference
manual for specific instructions and warnings.
♦PCI Installation
1.Turn off and unplug your computer.
2.Remove the top cover of your computer.
3.Remove the expansion slot cover on the back panel of the computer.
4.Touch any metal part of your computer chassis to discharge any static
electricity that might be on your clothes or body.
5.Insert the device into a 5 V PCI slot. Gently rock the device to ease it
into place. It may be a tight fit, but do not force the device into place.
6.Screw the mounting bracket of the device to the back panel rail of the
computer.
7.Visually verify the installation.
8.Replace the top cover of your computer.
9.Plug in and turn on your computer.
♦PXI Installation
1.Turn off and unplug your computer.
2.Choose an unused PXI slot in your system. For maximum
performance, the device has an onboard DMA controller that can only
be used if the device is installed in a slot that supports bus arbitration,
or bus master cards. National Instruments recommends installing the
device in such a slot. The PXI specification requires all slots to support
bus master cards, but the CompactPCI specification does not. If you
install in a CompactPCI non-master slot, you must disable the device
onboard DMA controller using software.
3.Remove the filler panel for the slot you have chosen.
4.Touch any metal part of your computer chassis to discharge any static
electricity that might be on your clothes or body.
5.Insert the device into a 5 V PXI slot. Use the injector/ejector handle to
fully insert the device into the chassis.
6.Screw the front panel of the device to the front panel mounting rail of
the system.
7.Visually verify the installation.
8.Plug in and turn on your computer.
The device is installed. You are now ready to configure your hardware and
software.
6034E/6035E User Manual2-2www.natinst.com
Hardware Configuration
Due to the National Instruments standard architecture for data acquisition
and standard bus specifications, these devices are completely
software-configurable. You must perform two types of configuration on the
devices—bus-related and data acquisition-related configuration.
The PCI devices are fully compatible with the industry-standard PCI Local
Bus Specification Revision 2.1. The PXI device is fully compatible with the
PXI Specification Revision 1.0. These specifications let your computer
automatically set the device base memory address and interrupt channel
with no user interaction.
You can modify data acquisition-related configuration settings, such as
analog input range and mode, through application-level software. Refer to
Chapter 3, Hardware Overview, for more information about the various
settings available for your device. These settings are changed and
configured through software after you install your device. Refer to your
software documentation for configuration instructions.
The analog input section of each device is software configurable. The
following sections describe in detail each of the analog input settings.
The devices have three different input modes—nonreferenced single-ended
(NRSE) input, referenced single-ended (RSE) input, and differential
(DIFF) input. The single-ended input configurations provide up to
16 channels. The DIFF input configuration provides up to eight channels.
Input modes are programmed on a per channel basis for multimode
scanning. For example, you can configure the circuitry to scan
12 channels—four differentially-configured channels and eight
single-ended channels. Table 3-1 describes the three input configurations.
Input Range
Table 3-1.
ConfigurationDescription
DIFFA channel configured in DIFF mode uses two analog
input lines. One line connects to the positive input of
the device’s programmable gain instrumentation
amplifier (PGIA), and the other connects to the
negative input of the PGIA.
RSEA channel conf igured in RSE mode uses one analog
input line, which connects to the positive input of the
PGIA. The negative input of the PGIA is internally
tied to analog input ground (AIGND).
NRSEA channel configured in NRSE mode uses one
analog input line, which connects to the positive
input of the PGIA. The negative input of the PGIA
connects to analog input sense (AISENSE).
For diagrams showing the signal paths of the three conf igurations, refer to
the Analog Input Signal Overview section in Chapter 4, Signal
Connections.
The devices have a bipolar input range that changes with the programmed
gain. Each channel may be programmed with a unique gain of 0.5, 1.0, 10,
or 100 to maximize the 16-bit analog-to-digital converter (ADC)

Multichannel Scanning Considerations
The devices can scan multiple channels at the same maximum rate as their
single-channel rate; however, pay careful attention to the settling times for
each of the devices. No extra settling time is necessary between channels
as long as the gain is constant and source impedances are low. Refer to
Appendix A, Specifications, for a complete listing of settling times for each
of the devices.
When scanning among channels at various gains, the settling times may
increase. When the PGIA switches to a higher gain, the signal on the
previous channel may be well outside the new, smaller range. For instance,
suppose a 4 V signal is connected to channel 0 and a 1 mV signal is
connected to channel 1, and suppose the PGIA is programmed to apply a
gain of one to channel 0 and a gain of 100 to channel 1. When the
multiplexer switches to channel 1 and the PGIA switches to a gain of 100,
the new full-scale range is ±50 mV.
Measurement Precision

305.2 µV

1.53 µV
The approximately 4 V step from 4 V to 1 mV is 4,000% of the new
full-scale range. It may take as long as 100 µs for the circuitry to settle to
1 LSB after such a large transition. In general, this extra settling time is not
needed when the PGIA is switching to a lower gain.
Settling times can also increase when scanning high-impedance signals
due to a phenomenon called charge injection, where the analog input
multiplexer injects a small amount of charge into each signal source when
that source is selected. If the impedance of the source is not low enough,
the effect of the charge—a v oltage error—will not have decayed by the time
the ADC samples the signal. For this reason, keep source impedances under
1kΩ to perform high-speed scanning.
Due to the previously described limitations of settling times resulting from
these conditions, multiple-channel scanning is not recommended unless
sampling rates are low enough or it is necessary to sample several signals
as nearly simultaneously as possible. The data is much more accurate and
channel-to-channel independent if you acquire data from each channel
independently (for example, 100 points from channel 0, then 100 points
from channel 1, then 100 points from channel 2, and so on.)
These devices supply two channels of 12-bit analog output voltage at the
I/O connector. The bipolar range is fixed at ±10 V. Data written to the
digital-to-analog converter (D A C) will be interpreted as two’ s complement
format.
Analog Output Glitch
In normal operation, a DAC output will glitch whenever it is updated with
a new value. The glitch energy differs from code to code and appears as
distortion in the frequency spectrum.
Digital I/O
The devices contain eight lines of digital I/O (DIO<0..7>) for
general-purpose use. You can individually software-configure each line for
either input or output. At system startup and reset, the digital I/O ports are
all high impedance.
The hardware up/down control for general-purpose counters 0 and 1 are
connected onboard to DIO6 and DIO7, respectively. Thus, you can use
DIO6 and DIO7 to control the general-purpose counters. The up/down
control signals are input only and do not affect the operation of the DIO
lines.
6034E/6035E User Manual3-4www.natinst.com
Timing Signal Routing
The DAQ-STC chip provides a flexible interface for connecting timing
signals to other devices or external circuitry. Your device uses the RTSI
bus to interconnect timing signals between devices, and the Programmable
Function Input (PFI) pins on the I/O connector to connect the device to
external circuitry. These connections are designed to enable the device to
both control and be controlled by other devices and circuits.
There are a total of 13 timing signals internal to the DAQ-STC that can be
controlled by an external source. These timing signals can also be
controlled by signals generated internally to the DAQ-STC, and these
selections are fully software-configurable. Figure 3-2 shows an example of
the signal routing multiplexer controlling the CONVERT* signal.

CONVERT* Signal Routing
This figure shows that CONVERT* can be generated from a number of
sources, including the external signals RTSI<0..6> and PFI<0..9> and the
internal signals Sample Interval Counter TC and GPCTR0_OUT.
Many of these timing signals are also available as outputs on the R TSI pins,
as indicated in the RTSI Triggers section in this chapter, and on the PFI
pins, as indicated in Chapter 4, Signal Connections.
Programmable Function Inputs
Ten PFI pins are available on the device connector as PFI<0..9> and are
connected to the device’s internal signal routing multiplexer for each
timing signal. Software can select any one of the PFI pins as the external
source for a given timing signal. It is important to note that any of the PFI
pins can be used as an input by any of the timing signals and that multiple
timing signals can use the same PFI simultaneously. This flexible routing
scheme reduces the need to change physical connections to the I/O
connector for different applications.
You can also individually enable each of the PFI pins to output a specific
internal timing signal. For example, if you need the UPD ATE* signal as an
output on the I/O connector, software can turn on the output driver for the
PFI5/UPDATE* pin.
Device and RTSI Clocks
Many device functions require a frequency timebase to generate the
necessary timing signals for controlling A/D conversions, DAC updates, or
general-purpose signals at the I/O connector.
These devices can use either its internal 20 MHz timebase or a timebase
received over the RTSI bus. In addition, if you configure the device to use
the internal timebase, you can also program the device to drive its internal
timebase over the R TSI b us to another device that is programmed to recei ve
this timebase signal. This clock source, whether local or from the R TSI bus,
is used directly by the device as the primary frequency source. The default
configuration at startup is to use the internal timebase without driving the
RTSI bus timebase signal. This timebase is software selectable.
♦PXI-6035E
The RTSI clock connects to other devices through the PXI trigger bus on
the PXI backplane. The R TSI clock signal uses the PXI trigger <7> line for
this connection.
6034E/6035E User Manual3-6www.natinst.com
RTSI Triggers
Chapter 3Hardware Overview
The seven RTSI trigger lines on the RTSI bus provide a very flexible
interconnection scheme for any device sharing the RTSI bus. These
bidirectional lines can drive any of eight timing signals onto the RTSI bus
and can receive any of these timing signals. This signal connection scheme
is shown in Figure 3-3 for PCI devices and Figure 3-4 for PXI devices.
Refer to the Timing Connectionssection of Chapter 4, Signal Connections,
for a description of the signals shown in Figures 3-3 and 3-4.
6034E/6035E User Manual3-8www.natinst.com
Signal Connections
This chapter describes how to make input and output signal connections to
your device via the I/O connector.
The I/O connector for the devices has 68 pins that you can connect to
68-pin accessories with the SH6868 shielded cable or the R6868 ribbon
cable. You can connect your device to 50-pin signal accessories with the
SH6850 shielded cable or R6850 ribbon cable.
