The OME-PCI-1800 Series is a
family of high-performance data
acquisition boards for the PCI bus.
It features continuous, 330 kHz,
gap-free data acquisition under
DOS and Windows.

The OME-PCI-1800 family has
two 12-bit D/A output channels,
16 digital input channels, and
16 digital output channels.
The OME-PCI-1800H and
OME-PCI-1800L provide 16
single-ended or 8 differential inputs.

The OME-PCI-1802H and
OME-PCI-1802L provide 32
single-ended or 16 differential
inputs. The suffix “H” denotes a
high-gain model and the “L” denotes
a low-gain model. The boards
feature advanced scanning
features. The scanning mechanism
not only scans the different input
channels at vastly different rates,
but also at different gains. Even in
multichannel scan mode, the
sampling rates can be maintained
at 330 KS/s.

The OME-PCI-1800 Series also
has some outstanding features,
including:

•

Data transfer rate of digital I/O
is up to 5.4 MB

•

Throughput of D/A is up
to 2 MHz (max)

•

Three flexible external trigger
modes such as post-trigger,
pre-trigger, middle trigger

•

True “plug & play” under DOS
and Windows

•

OME-PCI-1800 Series
System Expansion

Several daughter boards are
available that can expand the
analog and digital I/O capability
of the OME-PCI-1800 Series
high-performance data acquisition
boards. These include:
OME-DB-1825, OME-DB-8225,
OME-DB-8025, OME-DB-889D,
OME-DB-16P, OME-DB-16R.

OME-DB-889D 16-Channel
Analog Multiplexer Board

The OME DB-889D is an expansion
multiplexer/amplifier board for use
with OME-PCI-1800H/L boards.
Each OME-DB-889D multiplexes
16 differential analog input channels
into one analog input of the data
acquisition board. The high-grade
instrumentation amplifier provides
software programmable gains of

0.5, 1, 5, 10, 50, 100, 500, and

1000. Thermocouple measurements
are handled easily with the OME-DB­889D. The board includes cold­junction sensing and compensation
circuitry that provides a scaling of

24.4 mV/°C. Biasing resistors are
included for open thermocouple
detection. The OME-DB-889D can
be cascaded to a total of 128
channels of voltage measurements
or 112 channels of thermocouple
measurement.

OME-DB-16P 16-Channel
Isolated Digital Input Board

The OME-DB-16P is a 16-channel
isolated digital input daughter board
for any of the OME-PCI­1802H/1802L/1800H/1800L/1602/
1602F/1202H/1202L/1002H/1002L
PCI-bus multifunction boards.
The optically isolated inputs of the
OME-DB-16P consist of a bi­directional OPTO-coupler with
a resistor for current sensing. The
OME-DB-16P can be used to sense
DC signals from TTL levels up to
24 V and also a wide range of AC
signals. The OME-DB-16P can also
be used to isolate the computer
from large common-mode voltages,
ground loops and voltage spikes
that often occur in industrial
environments.

OME-DB-16R 16-Channel
Relay Output Board

The OME-DB-16R 16-channel relay
output board consists of 16 Form C
relays for efficient switching of loads
by programmed control.

The OME-DB-16R can be used with
any of the OME-PCI-1802H/1802L/
1800H/1800L/1602/1602F/1202H/
1202L/1002H/1002L PCI-bus
multifunction boards. The relays are
energized by applying a 5 V signal
to the appropriate relay channel on
the 20-pin flat cable connector.
Sixteen annunciator LEDs, one for
each relay, light when their associated
relay is activated. To avoid
overloading the PC’s power supply,
this board provides a screw terminal
connection for a power supply.

Software
Development Kit

All data acquisition boards are
supplied with a standard software
development kit for Windows
98/NT/2000/XP. The software
development kit includes DLL
files for programming in C, C++,
or other high-level languages,
and OCX files
for Visual Basic
or Active X
programming.
LabVIEW drivers

are also included.
