The DaqBoard/2000 Series plug-in boards provide
cost-effective, high-speed data acquisition

The DaqBoard/2000 Series sets the price/performance benchmark for high-speed,
multifunction plug-and-play data acquisition for PCI bus computers. The
DaqBoard/2000 Series hardware designoffers all of the features normally foundon significantly more expensive boards,
including 16-bit, 200 kHz A/D, 100% ­digital
calibration, bus mastering, two or four
16-bit, 100 kHz D/A converters, 40 digital
I/O lines, four counters, and two timers.
DaqBoard/2000 Series is supported by a
growing family of over 40 signal conditioning and expansion options, offering signal
conditioning for thermocouples, RTDs,
accelerometers, isolation, high-voltage,strain gages, and much more. Up to 528
channels of analog and digital I/O can beaccessed using one DaqBoard/2000, while
maintaining the 5 µs per channel update
rate. Up to four DaqBoard/2000s can beinstalled into one PC.
In total, the DaqBoard/2000 Series sets theindustry standard for plug-and-play PCI
data acquisition.

Synchronous I/O for
High-Speed Applications
The DaqBoard/2000 Series sets a new
standard with its ability to make analog
measurements, read digital inputs, andread counter inputs, while synchronously
generating up to four analog outputs
and/or a 16-bit digital pattern output. Most
other boards require CPU interaction toaccess I/O other than analog ­input, making it impossible to generate time-criticalanalog waveforms or digital patterns. With
the DaqBoard/2000 ­Series, the true powerof todays’ PCI-based PCs can be unleashed.
The same synchronous features of the
DaqBoard extend to its family of DBK ­signal
conditioning and expansion options. Up to
256 analog input channels and 272 (256,P2 only) digital I/O channels can also beaccessed synchronously to one another,with precise and deterministic channelto-channel timing. Up to four DaqBoards
can be installed in one PC, quadrupling
the channel capacity to over 1,000 analog
input channels, 1,000 digital I/O channels
and 16 high-speed analog output channels.

Signal I/O
One 100-pin connector on the
DaqBoard/2000 Series provides access toall of the input and output signals. Unlike
other multifunction boards that require
multiple PC slots in order to access all of the
I/O, careful design of the DaqBoard/2000
Series accommodates all I/O using one
cable, and utilizing a single PCI slot.
The 100-pin DaqBoard/2000 Series I/O connector, P4, is logically divided into three
sub-ports, P1, P2, and P3. P1, the analog
input port, contains all of the analog input
channels, as well as the sequencer control
signals for accessing external analog input
options. All analog expansion options attach to the P1 port. P2, the general purpose
digital I/O port, can be used directly tocontrol and monitor 24 digital I/O lines.
P2 can also function as the digital I/O
expansion port, whereby the 24 lines are
exclusively used to control external digital
DBK expansion options, for up to 256 linesof digital input or output. P3 contains anadditional 16-bit digital I/O port, as wellas the counter inputs, timer outputs, andanalog outputs. Several options are available to provide easy user access to all of
the I/O signals on P4.

Analog Input (P1)
The DaqBoard/2000 Series has a 16-bit,
200 kHz A/D coupled with 16 single-ended,or 8 differential analog inputs. Thirteen
software programmable ranges provide
inputs from ±10V to ±156 mV full scale.
Each channel can be software-configured fora different range, as well as for single-ended
or differential, and unipolar or bipolar input.
Beyond the 16 built-in analog inputs, theuser can expand the DaqBoard/2000 Series

Measurement Computing

up to 256 analog inputs using external DBK
signal conditioning and expansion options.
As with the on-board channels, expansion
channels are scanned at the same 5 µs/channel rate (200 kHz), and most are software-­programmable for range. There is no speed
penalty for scanning expansion channels
versus built-in channels. The DBK expansion options offer a wide variety of signal­measurements, including thermocouples,
RTDs, strain gages, accelerometers, high­voltage, isolation, ­current, and much more.

Scanning
The DaqBoard/2000 Series has an on-board
scan sequencer that permits the user to selectany combination of up to 512 c­hannel/
range combinations. The sequencer scans
all channels contained in the sequence at
the fastest rate of 5 µs/channel, thereby
minimizing the time-skew from channelto-channel. The user can also set the time
between scan groups, from 0 to 6 hours.
In addition to scanning analog inputs,
the sequencer can scan digital inputs andcounter inputs.

Bus Mastering DMA
The DaqBoard/2000 Series supports Bus
Mastering DMA, which allows analog anddigital/counter input data, as well as analog
and digital output data to flow between the
PC and the DaqBoard/2000 Series without
consuming valuable CPU time. The driver
supplied with the DaqBoard/2000, as well
as all other third-party software support
such as DASYLab® and NI LabVIEW®,
automatically utilize Bus Mastering DMA
to efficiently conduct I/O from the PC tothe DaqBoard.

Triggering
Triggering can be the most critical aspectof a data acquisition application. The
DaqBoard/2000 Series supports a full complement of trigger modes to a
­ ccommodate
any measurement situation.
Hardware Analog Triggering. Many dataacquisition boards claim analog triggering,
but rely on the PC to take readings andmake a decision, which leads to uncertain and potentially long latencies. The
DaqBoard/2000 Series uses true a­nalogtriggering, whereby the trigger level­programmed by the user sets an analog
DAC, which is then compared in hardware
to the analog input level on the selectedchannel. The result is analog trigger latency
which is guaranteed to be less than 5 µs,
significantly shorter than most data acquisition boards. Any analog channel can beselected as the trigger channel, including
built-in or expansion channels. The user
can program both the trigger level, as wellas the edge (rising or falling).
Digital and Pattern Triggering (P1). A separate digital trigger input line is provided,
allowing TTL-level triggering, again withlatencies guaranteed to be less than 5 µs.
Both the logic levels (1 or 0), as well as theedge (rising or falling), can be programmed
for the discrete d­ igital trigger input.
Software-Based Triggering. Software-based
triggering differs from the modes describedabove because the readings, analog, digital, or
counter, are interrogated by the PC to detect
the trigger event, not in the hardware as described above. The advantage of this mode isto permit ­triggering based on more complex­situations, such as on a specific temperature,
which was derived from the acquisition of

at least two analog measurements, plus thecalculation of the measured t­ emperature using linearization algorithms.
The DaqBoard/2000 Series also supports
digital pattern triggering, whereby theuser can designate any of the digital input
ports as the trigger port. The programmed
digital pattern, including the ability tomask or ignore specific bits, is then compared to the actual input until a matchis detected, after which the sequencer­begins the scan sequence.
Triggering can also be programmed to ­occur
when one of the counters reaches, exceeds,
or is within a programmed level. Any ofthe built-in counter/­totalizer c­ hannels canbe ­programmed as a trigger source.
Normally software-based triggering resultsin long latencies from the time that a trigger condition is detected, until the actual
capturing of data commences. However,Measurement Computing

the DaqBoard/2000 Series circumvents
this undesirable phenomenon by useof pre-trigger data. Specifically, whensoftware-based triggering is employed,
and the PC detects that a trigger condition
has occurred, (which may be thousandsof readings later than the actual occurrence of the signal), the DaqBoard driver
automatically looks back to the location inmemory where the actual trigger-causing
measurement occurred. The acquired datathat is presented to the user actually begins
at the point where the ­trigger-causing
measurement occurs. The latency in thismode is equal to one scan cycle.
Stop Trigger. Any of the software trigger
modes described above can also be used tostop an acquisition. Thus an ­acquisition
can be programmed to begin on one event,such as a temperature level, and thencan stop on another event, such as adigital pattern.

Pre- and Post-Triggering Modes. Six modesof pre- and post-triggering are supported,
providing a wide variety of options toaccommodate any measurement requirement. When using pre-trigger, the user
must use software-based triggering to­initiate an acquisition.
No pre-trigger, post-trigger stop event. This,
the simplest of modes, acquires data uponreceipt of the trigger, and stops acquiring
upon receipt of the stop-trigger event.
Fixed pre-trigger with post-trigger stop
event. In this mode, the user specifies thenumber of pre-trigger readings to be acquired, after which, acquisition c­ ontinues
until a stop-trigger event occurs.
No pre-trigger, infinite post-trigger. No
pre-trigger data is acquired in this mode.
Instead, data is acquired beginning withthe trigger event, and is terminated when
the operator issues a command to halt
the acquisition.

The user specifies the amount of pre-­trigger

Variable pre-trigger with post-trigger stop
event*. Unlike the previous pre-trigger
modes, this mode does not have to satisfy
the pre-trigger number of readings before
recognizing the trigger event. Thus thenumber of pre-trigger readings acquired isvariable and dependent on the time of thetrigger event relative to the start. In thismode, data continues to be acquired until
the stop trigger event is detected.

Channel-Scanning Flexibility
The DaqBoard/2000 Series offers a 512-location scan sequencer that allows you toselect each channel and associated input amplifier gain at random. The sequencer
circuitry circumvents a major limitation encountered with many plug-in data acquisition boards—a drastic reduction in the scan rate for external expansion channels.
All DaqBoard/2000 Series channels, including the 528 potential expansion channels,
are scanned at 100K or 200 kHz (1 or 5 µs/channel), software programmable perchannel. In addition, the digital and frequency inputs can be scanned using thesame scan sequence employed for analog inputs, enabling the time correlation of
acquired digital data to acquired analog data. The DaqBoard/2000 Series permits
each scan group, which can contain up to 512 channel/gain combinations, tobe repeated immediately or at programmable intervals of up to 6 hours. Withineach scan group, consecutive channels are measured at a fixed 5 µs/channel rate.

DaqBoard/2000 Series Scanning Example

Variable pre-trigger with infinite post-­
trigger*. This is similar to the mode
­described above, except that the acquisitionis terminated upon receipt of a commandfrom the program to halt the acquisition.

tProgrammable,from 5 �s up to

Calibration
Every range on the DaqBoard/2000 Series iscalibrated from the factory using a digital
calibration method. This method works
by storing a correction factor for eachrange on the DaqBoard/2000 Series at thetime of calibration. Whenever a particularrange is selected, the appropriate calibration constant is automatically applied to acompensating DAC, thereby calibrating thespecific range. The result is that readings
generated by the A/D are already calibrated,and do not ­require additional processing.
This is significantly better than otherboards, that merely adjust the readings insoftware after they are transferred to the
PC. That method has the disadvantage ofreducing the dynamic range of the A/D,
and can adversely affect the speed at which
the PC can obtain a calibrated reading.
The DaqBoard/2000 Series also has auser-cal mode, whereby the user can adjust the calibration of the board in theirsystem, without destroying the factory­calibration supplied with the board. Thisis ­accomplished by having 2 distinct calibration tables in the DaqBoard/2000 Series
on-board EPROM, one which contains thefactory cal, and the other which is available
for user calibration.

Analog Output (P3)
DaqBoard/2000, & /2001 Only
Two or four 16-bit, 100 kHz analog output
channels are built into the DaqBoard/2000
Series, with an output from -10V to +10V.
These outputs are entirely separate fromthe D/As which are used to determine
analog trigger level (some data acquisitionboard suppliers confusingly refer to trigger
D/As as if they are available to the user).
Through the use of Bus Mastering DMA,

each D/A output can continuously output
a waveform, which can be read from PC
RAM or a file on the hard disk. In addition,a program can asynchronously output avalue to either of the D/As for non-waveform
applications, presuming that the D/A is not­ eing used in the waveform output
already bmode. Additional low-speed D/A channels
can be added to the DaqBoard through theuse of the DBK2 analog output option card.

General Information

When used to generate waveforms, theD/As can be clocked in several different
modes. Each D/A can be separately selected
to be clocked from one of the sources
described below.
Asynchronous Internal Clock. The on-board
programmable clock can generate updates
ranging from 1.5 Hz to 100 kHz, ­independentof any acquisition rate.
Synchronous Internal Clock. The rate ofanalog output update can be synchronized
to the acquisition rate derived from 100 kHz
to once every 5.96 hours.
Asynchronous External Clock. A user-­supplied external input clock can be used
to pace the D/A, entirely i­ndependent of
analog inputs.
Synchronous External Clock. A user-­supplied external input clock can pace
both the D/A and the analog input.

Digital Pattern­Generation (P3)The DaqBoard/2000 Series supports digitalpattern generation via Bus Mastering DMA
on the 16-bit high-speed digital I/O port.
In the same manner as Analog Output, thedigital pattern can be read from PC RAM ora file on the hard disk. Digital pattern generation is clocked in the same four modesas ­described above with ­analog output*.

Digital Inputs and­Outputs (P2, P3)
Forty TTL-level digital I/O lines are included in the DaqBoard/2000 Series. They
are divided into three 8-bit ports (P2) andone 16-bit port (P3). The P2 ports can be
programmed in 8-bit groups as either input or output. The 16-bit P3 port can be
programmed as all inputs or all outputs.
Ports programmed as inputs can be partof the scan group and scanned along withother analog and digital input channels,
or can be asynchronously accessed via the
PC at any time, including when a scanned
acquisition is occurring.

General Information & Expansion Options
Timer Outputs (P3)

In addition, the P2 ports can be expanded up to 256 digital
I/O lines using external DBK digital options. These options areavailable as TTL-level I/O, relay output, or optically isolated
input and output. Whenever expansion digital I/O is attachedto the DaqBoard/2000 Series, the P2 I/O lines are no longer userprogrammable, and are ­instead used to ­communicate with the­digital expansion options.

Two 16-bit timer outputs are built into the DaqBoard/2000, eachcapable of generating different square waves with a programmablefrequency range from 16 Hz to 1 MHz.

Multiple DaqBoards per PC
All of the features described for the DaqBoard/2000 can be replicated with up to four DaqBoard/2000s installed in the same PC.
The ­serial number on each DaqBoard/2000 is used to differentiate
one from another, and a user-selected name can be assigned toeach board for easy program documentation. Thus, with fourboards installed along with DBK expansion options, over 1,000
analog input channels and over 1,000 digital I/O channels could
be accessed from one PC. When multiple boards are installed,
all boards can be operated synchronously.

Counter Inputs (P3)
Four 16-bit counters are built into the DaqBoard/2000, each capableof counting up to 65,536 TTL-level transitions. Each of the four
counters will accept frequency inputs up to 10 MHz, and can be
configured for pulse count or totalize mode. The counters can also
be cascaded, allowing over four billion counts to be accumulated.
As with all other inputs to the DaqBoard/2000 Series, the counter
inputs can be read asynchronously under program control, or
synchronously as part of an analog and ­digital scan group.

DBK213 Expansion Module

DBK214 Expansion Module

The DBK213 module provides screw-­
terminal access plus
­expansion slots for the DaqBoard/2000 Series. The top of the
DBK213 is easily removed to reveal screw-terminal connections
that provide access to all analog and digital I/O from the hostdata acquisition b­ oard. Also included with the DBK213 are three
expansion slots that can accommodate any DBK analog or digital
expansion and signal conditioning cards.

The DBK214 module provides 16 BNC connectors for accessing
analog I/O, digital I/O, or counter/timer signals. In addition, screw-­
terminal connections for all signals are accessed by removing the
DBK214’s top cover. Eight of the BNC connectors are pre-defined
as analog inputs and are jumper selectable as single ended ordifferential. Another eight BNC connectors can be configuredby the user on a per channel basis as an analog input or output,
digital I/O, or counter/timer channels.

* When digital pattern generation is used, one of the analog output channels is
limited to ­asynchronous output mode

DBK202 Screw-Terminal Adapter Board
The DBK202 screw-terminal board provides convenient screw-­
terminal access to all signals from the DaqBoard/2000 Series. Divided into three ports (P1, P2, and P3), the DBK202 also provides
another way to access signals. There are male DB37 connectors on
P1 and P2 which can be used to connect to DBK signal conditioning
and expansion options. Mounting holes in the DBK202 permit it
to be easily screw-mounted into a user-provided enclosure.

DaqBoard/2000 Series
Expansion Options

DaqBoard/2000 Series Expansion Options for Rack-Mount Systems
analog input boards are daisy chained to the DBK206, and up to eight
DBK210 boards are daisy chained to the DBK206. The total I/O insuch a system is 256 analog input channels (via DBK207), 256 digital
I/O channels (via DBK210), plus four frequency inputs, two timer
outputs, four analog outputs and 16 TTL digital I/O via the DBK206.
All analog, digital and frequency channels can be scanned at
5 µsec/­channel (in the case of digital I/O, 16 channels per 5 µsec
is possible).

The DaqBoard/2000 Series can be expanded up to 100s of analog
and digital channels in a rack-mount system, with only one cableback to the DaqBoard. This is possible because of the uniquecapability built into the DaqBoard/2000 Series and the DBK200
Series options. Specifically, the DBK206, DBK207, DBK208, andDBK210 have on-board multiplexing and daisy-chain capability,
which means that only one DBK board within the rack system isconnected to the DaqBoard, and all other DBK boards are daisychained ­together (see diagram).

For applications with higher channel r­equirements, up to four
DaqBoards can be installed into one PC, for a total channel ­capacitythat is 4x a single DaqBoard s­ ystem.

In the example system described here, one CA-195 connects the
DBK206 screw-terminal board to the PC, while up to 16 DBK207

The DBK210 offers similar functionality as the DBK208 but withtwice the channel capacity per board. The DBK210 is the same
size physically as the DBK208 but by using the Grayhill 70M Series solid state relay modules (sold separately), provides space for
32 isolated d­ igital I/O. These modules feature a narrower footprint­allowing for high-density channel c­ apacity.
