The OMB-DAQBOARD-2000 Series
sets the price/performance
benchmark for high-speed,
multifunction plug-and-play data
acquisition for PCI bus computers.
The hardware design offers all the
features normally found on
significantly more expensive boards,
including 16-bit, 200 kHz A/D; 100%
digital calibration; bus mastering,
two or four 16-bit, 100 kHz A/D
converters; 40 digital I/O lines;
4 counters; and 2 timers.

The OMB-DAQBOARD-2000 Series
is supported by a growing family
of over 30 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
be accessed with one
OMB-DAQBOARD-2000, while
maintaining the 5 µs per channel
update rate. Up to 4
OMB-DAQBOARD-2000s can
be installed into one PC.

The OMB-DAQBOARD-2000 has
more extensive software capabilities
than most other boards, with
comprehensive drivers for nearly
every programming environment
supported by Windows 95 and
higher. Included in this list are
Visual Basic, C++, Delphi,
TestPoint, LabVIEW, and
DASYLab, and C++ for Linux.
Also included is a suite of DaqView
software options for setup,
acquisition, display, and analysis
of acquired data—no programming

Synchronous I/O
for High-Speed Applications

The OMB-DAQBOARD-2000 Series
sets a new standard with its ability
to make analog measurements,
read digital inputs, and read counter
inputs, while synchronously
generating up to 4 analog outputs
and/or a 16-bit digital pattern output.
Most other boards require CPU
interaction to access I/O other than
analog input, making it impossible to
generate time-critical analog
waveforms or digital patterns. With
the OMB-DAQBOARD-2000 Series,
the true power of PCI-based PCs
can be unleashed.

The same synchronous features of
the OMB-DAQBOARD-2000 extend
to its family of OMB-DBK signal
conditioning and expansion options.
Up to 256 analog input channels
and 272 (P2 only) digital I/O
channels can also be accessed
synchronously to one another, with
precise and deterministic channel­to-channel timing. Up to 4
OMB-DAQBOARD-2000s can be
installed in one PC, quadrupling the
channel capacity to over 1000
analog input channels, 1000 digital
I/O channels, and 16 high-speed
analog output channels.

Signal I/O

One 100-pin connector on the
OMB-DAQBOARD-2000 Series
provides access to all the
input and output signals. Unlike
other multifunction boards that
require multiple PC slots, the
OMB-DAQBOARD-2000 Series
accommodates all I/O using one
cable and has only one PCI slot.

The 100-pin OMB-DAQBOARD/2000
Series I/O connector, P4, is logically
divided into 3 subports: P1, P2, and

D1-2

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
to control 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 OMB-DBK
expansion options, for up to 256
lines of digital input or output. P3
contains an additional 16-bit digital
I/O port, as well as the counter
inputs, timer outputs, and analog
outputs. Several options are
available to provide easy user
access to all of the I/O signals on P4.

Analog Input (P1)

The OMB-DAQBOARD-2000 Series
has a 16-bit, 200 kHz A/D coupled
with 16 single-ended or 8 differential
analog inputs. Thirteen software­programmable ranges provide
inputs from ±10 V to ±156 mV full
scale. Each channel can be
software configured for a different
range, as well as for single-ended or
differential and unipolar or bipolar
inputs. Beyond the 16 built-in
analog inputs, the user can expand
the OMB-DAQBOARD-2000 Series
up to 256 analog inputs using
external OMB-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 OMB-DBK expansion
options offer a wide variety of signal
measurements, including
thermocouples, RTDs, strain gages,
accelerometers, high voltage,
isolation, current, and much more.

ANALOG INPUT AND

MULTIFUNCTION CARDS

Scanning

The OMB-DAQBOARD-2000 Series
has an on-board scan sequencer
that permits the user to select any
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 channel-to-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 and counter inputs.

Channel-Scanning
Flexibility

The OMB-DAQBOARD-2000 Series
offers a 512-location scan
sequencer that allows the user to
select 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 OMB-DAQBOARD-2000
Series channels, including
the 528 potential expansion
channels, are scanned at 200 kHz
(5 µs/channel). In addition, the digital
and frequency inputs can be scanned
by using the same scan sequence
employed for analog inputs, enabling
the time correlation of acquired
digital data to acquired analog data.
The OMB-DAQBOARD-2000 Series
permits each scan group, which can
contain up to 512 channel/gain
combinations, to be repeated
immediately or at a programmable
interval of up to 6 hours. Within
each scan group, consecutive
channels are measured at a fixed
5 µs/channel rate.

Bus Mastering DMA

The OMB-DAQBOARD-2000 Series
supports bus mastering DMA, which
allows analog and digital/counter input
data, as well as analog and digital
output data, to flow between the PC
and the OMB-DAQBOARD-2000
Series without consuming valuable
CPU time.

The driver supplied with the
OMB-DAQBOARD-2000, as well as
all other third-party software support
such as TestPoint, LabVIEW, and

Triggering

Triggering can be the most critical
aspect of a data acquisition application.
The OMB-DAQBOARD-2000 Series
supports a full complement of
trigger modes to accommodate any
measurement situation.

Hardware Analog Triggering

Many data acquisition boards claim
analog triggering, but rely on the PC
to take readings and make a
decision, which leads to uncertain
and potentially long latencies. The
OMB-DAQBOARD-2000 Series
uses true analog triggering,
whereby the trigger level
programmed by the user sets an
analog DAC, which is then
compared in hardware to the analog
input level on the selected channel.
The result is analog trigger latency
that is guaranteed to be less than
5 µs, significantly shorter than that
of most data acquisition boards.

Any analog channel can be selected
as the trigger channel, including
built-in or expansion channels. The

Uni

Expansion channels (up to

rate as on-board channels

user can program both the trigger
level and the edge (rising or
falling).

Digital and Pattern
Triggering (P1)

A separate digital trigger input line
is provided, allowing TTL-level
triggering, again with latencies
guaranteed to be less than 5 µs.
Both the logic levels (1 or 0) and
the edge (rising or falling) can be
programmed for the discrete
digital trigger input.

Software-Based Triggering

Software-based triggering differs
from the modes described above
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 is to permit triggering
based on more complex
situations, such as on a specific
temperature, which was derived
from the acquisition of at least
2 analog measurements, plus the
calculation of the measured
temperature using linearization
algorithms.

The OMB-DAQBOARD-2000 Series
also supports digital pattern
triggering, whereby the user can
designate any of the digital input
ports as the trigger port. The
programmed digital pattern, including
the ability to mask or ignore specific
bits, is then compared to the actual
input until a match is detected, after
which the sequencer begins the
scan sequence. Triggering can also
be programmed to occur when one
of the counters reaches, exceeds,
or is within a programmed level.
Any of the built-in counter/totalizer
channels can be programmed as a
trigger source. Normally software­based triggering results in long
latencies from the time that a trigger
condition is detected until the actual
capturing of data commences. However,
the OMB-DAQBOARD-2000 Series
circumvents this undesirable
phenomenon by use of pre-trigger
data. Specifically, when
software-based triggering is
employed and the PC detects that a
trigger condition has occurred
(which may be thousands of
readings later than the actual
occurrence of the signal), the OMB­DAQBOARD-2000 driver
automatically looks back to the
location in memory where the actual
trigger-causing measurement
occurred. The acquired data that
are presented to the user actually
begin at the point where the trigger­causing measurement occurs. The
latency in this mode is equal to one
scan cycle.

Stop Trigger

Any of the software trigger modes
described above can also be used
to stop an acquisition. Thus an
acquisition can be programmed to
begin on one event, such as a
temperature level, and then can
stop on another event, such as a
digital pattern.

No pre-trigger, post-trigger stop
event.

acquires data upon receipt of the
trigger, and stops acquiring upon
receipt of the stop-trigger event.

This, the simplest of modes,

readings to be acquired, after
which acquisition continues until a

. In this mode, the user

The user specifies

Variable pre-trigger with
post-trigger stop event (driver
support only).

pre-trigger modes, this mode does
not have to satisfy the pre-trigger
number of readings before
recognizing the trigger event. Thus
the number of pre-trigger readings
acquired is variable and dependent
on the time of the trigger event
relative to the start. In this mode,
data continue to be acquired until
the stop-trigger event is detected.

Unlike the previous

Variable pre-trigger with infinite
post-trigger (driver support only).

This is similar to the mode
described above, except that the
acquisition
is terminated upon receipt of a
command from the program to halt
the acquisition.

appropriate calibration constant is
automatically applied to a
compensating DAC, thereby
calibrating the specific 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 other
boards that merely adjust the
readings in software after they are
transferred to the PC. That method
has the disadvantage of reducing
the dynamic range of the A/D, and
can adversely affect the speed by
which the PC can obtain a calibrated
reading. The OMB-DAQBOARD-2000
Series also has a USERCAL mode,
whereby the user can adjust the
calibration of the board in his or her
system, without destroying the
factory calibration supplied with the
board. This is accomplished by
having 2 distinct calibration tables in
the OMB-DAQBOARD-2000 Series
on-board EPROM, one that contains
the factory calibration, and the other
that is available for user calibration.

Analog Output (P3)

OMB-DAQBOARD-2000, -2001,
and -2004 Only

Two or four 16-bit, 100 kHz
analog output channels are built into
the OMB DAQBOARD-2000 Series,
with an output from –10 V to 10 V.
These outputs are entirely separate
from the D/As which are used to
determine analog trigger level
(some data acquisition board
suppliers confusingly refer to trigger
D/As as if they are available to the
user). With 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 a value
to either of the D/As for non-waveform
applications, presuming that the D/A
is not already being used in the
waveform output mode.

Pre- and Post-Triggering
Modes

6 modes of pre- and post-triggering
are supported, providing a wide
variety of options to accommodate
any measurement requirement.

With pre-trigger, the user must
employ software-based triggering to
initiate an acquisition.

Calibration

Every range on the
OMB-DAQBOARD-2000 Series is
calibrated from the factory using a
digital calibration method. This
method works by storing a
correction factor for each range on
the OMB-DAQBOARD-2000 Series
at the time of calibration. Whenever
a particular range is selected, the

D1-4

Additional low-speed D/A
channels can be added to the
OMB-DAQBOARD-2000 through the
use of the OMB-DBK2 analog
output option card. When used to
generate waveforms, the D/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, independent of
any acquisition rate.

Synchronous Internal Clock

The rate of analog 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 Pattern Generation
(P3)

The OMB-DAQBOARD-2000 Series
supports digital pattern generation
via bus mastering DMA on the
16-bit high-speed digital I/O port.
Like analog output, the digital
pattern can be read from PC RAM
or a file on the hard disk. Digital
pattern generation is clocked in the
same 4 modes as analog output
(when digital pattern generation is
used, one of the analog output
channels is limited to asynchronous
output mode).

Digital Inputs and Outputs
(P2, P3)

Forty TTL-level digital I/O lines are
included in the OMB-DAQBOARD-2000
Series. They are divided into three
8-bit ports (P2) and one 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

OMB-DBK200, $39,

inputs can be part of the scan group
and scanned along with other
analog and digital input channels, or
can be asynchronously accessed
via the PC at any time, including
when a scanned acquisition is
occurring. In addition, the P2 ports
can be expanded up to 256 digital
I/O lines using external OMB-DBK
digital options. These options are
available as TTL-level I/O, relay
output, or optically isolated input
and output. Whenever expansion
digital I/O is attached to the
OMB-DAQBOARD-2000 Series,
the P2 I/O lines are no longer user
programmable, but are used to
communicate with the digital
expansion options.

Counter Inputs (P3)

Four 16-bit counters are built into
the OMB-DAQBOARD-2000, each
capable of counting up to 65,
536 TTL-level transitions. Each of
the 4 counters will accept frequency
inputs up to 10 MHz. The counters
can also be cascaded, allowing
over 4 billion counts to be accumulated.
As with all other inputs to the
OMB-DAQBOARD-2000 Series, the
counter inputs can be read
asynchronously under program
control, or synchronously as part of
an analog and digital scan group.

Timer Outputs (P3)

Two 16-bit timer outputs are built
into the OMB-DAQBOARD-2000,
each capable of generating
different square waves with a
programmable frequency range
from 16 Hz to 1 MHz.

Multiple OMB-DAQBOARD-2000s
Per PC

All of the features described for
the OMB-DAQBOARD-2000
can be replicated with up to

4 OMB-DAQBOARD-2000s
installed in the same PC.

Each OMB-DAQBOARD-2000 has
a serial number for identification,
and a user-selected name can be
assigned to each board for easy
program documentation. Thus, with
4 boards installed along with
OMB-DBK expansion options, over
1000 analog input channels and
over 1000 digital I/O channels could
be accessed from one PC. When
multiple boards are installed, all
boards can be operated synchronously.
The OMB-DAQBOARD-2000 Series
provides all I/O signals on one
100-pin connector. The following
adaptor options make it easy for the
user to attach signals and
expansion options to the
OMB-DAQBOARD-2000 Series.

OMB-DBK200
Adaptor Board

Suitable exclusively for analog-signal
expansion, the OMB-DBK200
adaptor board contains one 100-pin
connector that connects to the
OMB-DAQBOARD-2000 Series via
the OMB-CA-195 cable, and one
female DB37 connector that mates
directly with the P1 port of any of
the OMB-DBK analog signal
conditioning and expansion options.
This is the most convenient way to
add analog expansion options if
access to the OMB-DAQBOARD-2000
Series digital I/O or frequency
signals is not required. Access to
P1 analog signals is also possible
via included female-mating
solder-lug connectors or optional
OMB-CA-37-x or OMB-CA-37-xT
expansion cables.

OMB-DBK201 and OMB­DBK209 Adaptor Boards

For both analog and digital
expansion, the OMB-DBK201
adaptor board mates with the
OMB-DAQBOARD-2000 Series
via a 1 m (3') OMB-CA-195 cable.
The OMB-DBK209 provides 3 male
DB37 connectors, divided into P1
analog input, P2 digital
I/O, and P3 analog output and
counter/timer I/O. Each port
on the OMB-DBK201 connects to
OMB-DBK expansion options via
an optional OMB-CA-37-x or
OMB-CA-37-xT expansion cable.
Alternatively, users can solder wires
to the included DB37 female-mating
solder-lug connectors, or custom
make their own cables that are
terminated with a female DB37. An
optional 1.8 m (6') cable is available
that contains a mating female DB37
connector at one end, and is
unterminated at the other end
(OMB-CA-113). The OMB-DBK209
is identical in function to the OMB­DBK201 but is snap-track (DIN-rail),
and rack-mountable with optional
mounting kits.

OMB-DBK202
and OMB-DBK203 Screw­Terminal Adaptor Board

The OMB-DBK202 screw-terminal
board provides convenient
screw-terminal access to all signals
from the OMB-DAQBOARD-2000
Series. Divided into 3 ports (P1, P2,
and P3), the OMB-DBK202 also
provides another way to access
signals. There are male DB37
connectors on P1 and P2, and an
adaptor cable (OMB-CA-60) can
be used to connect to the P3
header for connection to DBK signal
conditioning and expansion options.

OMB-DBK207, $249, shown smaller than actual size

Mounting holes in the OMB-DBK202
permit it to be easily screw-mounted
into a user-provided enclosure. The
OMB-DBK203 is identical to the
OMB-DBK202, except that it is
housed in a shielded metal enclosure,
which easily mounts to other
OMB-DBK signal conditioning and
expansion modules. Optional
fastener panels are available for
attaching other OMB-DBK modules.

OMB-DBK206 Screw­Terminal Adaptor Board

Similar in function to the
OMB-DBK202, but designed for
mounting in 19-inch enclosures,
the OMB-DBK206 features three
vertically mounted straight male
DB37 connectors for analog and
digital channel expansion (P1
analog I/O, P2 digital I/O, and P3
digital and counter-timer, plus
analog output). Two rows of
removable screw terminals provide
convenient access to all
OMB-DAQBOARD-2000 Series
I/O-signals (10-22 AWG wire). It
mates with the OMB-DAQBOARD-2000
Series via a 1 m (3')

OMB-CA-195 cable, and each port
(P1, P2, and P3) connects to DBK
signal conditioning and expansion
options via optional OMB-CA-37-x
cable(s). The standard OMB-DBK206
can be panel mounted, but it also is
DIN-rail mountable and rack-mountable
with optional mounting kits.

OMB-DBK207
and OMB-DBK207/CJC
Multiplexing Isolated
Analog Input Board

The OMB-DBK207 provides sockets
for 16 channels of isolated analog
input when populated with industry­standard 5B-style or compatible
signal conditioning modules. Each
channel features screw terminals
and sockets for current conversion
resistors (supplied with 5B current
input modules). The OMB-DBK207/CJC
features added cold-junction
compensation per channel for
thermocouple-based measurements.

Multiplexing is built-in, allowing up
to 16 OMB-DBK207 boards to be
directly connected to one
OMB-DAQBOARD-2000 Series
board for a total signal capacity
of 256 isolated analog inputs.
The 100-pin P4 connector on the
OMB-DBK207 attaches directly
to the OMB-DAQBOARD-2000
(via OMB-CA-195 cable). Two DB37
connectors permit daisy chaining to
other OMB-DBK207 boards, and to
any of the other OMB-DBK analog
signal conditioning boards and
modules. The OMB-DBK207/CJC
and the OMB-DBK207 can be rack
or snap-track mounted with optional
mounting kits.

OMB-DBK208
Multiplexing—Isolated
Digital I/O Board

The OMB-DBK208 provides
sockets for 16 channels of isolated
digital I/O when populated with
industry-standard Opto-22 style or
compatible solid-state-relay modules.
Each socket also features screw
terminals and an LED to indicate
logic status. The 16 digital I/O can
be jumper configured as either
inputs or outputs in 8-channel groups.

Multiplexing is built-in,
allowing up to 16 OMB-DBK208
boards to be
OMB-DAQBOARD-2000
board, for a total signal capacity of
256 isolated digital I/O channels.
On-board logic ensures that outputs
are disabled during power-up and
by a CPU reset. Also included is the
ability to choose whether outputs
are “off” or in the “last known state”
when loss of external power occurs.

The 100-pin P4 connector on the
OMB-DBK208 attaches directly to
a OMB-DAQBOARD/2000 Series
board (via OMB-CA-195 cable),
while 2 DB37 connectors permit
daisy chaining to other OMB-DBK208
boards and to any of the other
OMB-DBK digital boards and modules.

ANALOG OUTPUTS
(2000, 2001 and 2004)

The 2 or 4 analog output channels
are updated synchronously relative
to scanned inputs, and clocked from
either an internal on-board clock or
an external clock source. Analog
outputs can be updated
asynchronously, independent of any
other scanning in the system. Bus
mastering DMA provides CPU and
system-independent data transfers,
ensuring accurate outputs
independent of other system
activities. Streaming from disk or
memory is supported, allowing
continuous, nearly infinite-length,
waveform outputs (limited only by
available PC system resources).
Channels: 2 (2000); 4 (2001
and 2004)

Resolution: 16-bit
Output Voltage Range: ±10 V
Clock Sources: 4, programmable

1. On-board D/A clock, independent

of scanning input clock

2. On-board scanning input clock
(2000, 2001 & 2004 only)

3. External D/A input clock,
independent of external scanning
input clock

4. External scanning input clock
(2000, 2001 and 2004 only)

DIGITAL I/O
