The OMB-DAQSCAN-2000 Series
of Ethernet-based data acquisition
system components provides
analog, digital and frequency I/O
capability for Ethernet-based test
systems.
All OMB-DAQSCAN-2000 models
are packaged in a 1U high-full rack
package and include a rack-mount
kit that can attach to either the front
DaqView Software Real-Time Chart
or the rear of the enclosure.
Multiple OMB-DAQSCAN models
can be combined in the same
system and synchronized using a
simple SYNC connection between
units. All I/O is accessed via female
DB37 connectors located at the rear
of the unit, making cabling easy
from the OMB-DAQSCAN-2000 to
your device-under-test.
The OMB-DAQSCAN-2000 Series
includes comprehensive drivers for
all popular Windows-based
environments, including Visual
Basic, C/C++, ActiveX/COM,
LabVIEW, MATLAB, and DASYLab.

Also included with the OMB-DAQSCAN-2000 Series
is DaqView, an interactive spreadsheet-style
application that is ideal for verifying signal
connections during system design.
The compact 1U high 19” rack packaging of the
OMB-DAQSCAN-2000 make it a compact component
for rack-based systems. In addition to the built-in I/O
provided by the OMB-DAQSCAN-2000 Series, a wide
variety of signal conditioning and expansion options
are available.

Below are some sample systems that can be
derived from the OMB-DAQSCAN-2000 along
with OMB-DBK options.
High Channel Count
Thermocouple Measurements
When combined with the OMB-DBK90 thermocouple
input module, the OMB-DAQSCAN-2000 Series can
measure up to 896 channels of T/C input. In the
example system to the right, any T/C type can be
installed into any channel using standard mini T/C
connectors. Each 56-channel OMB-DBK90 option
consumes 2U of rack space and can be mounted
on the front or rear of the rack chassis. Built-in cold
junction compensation coupled with T/C conversion
algorithms built into the software make temperature
measurements easy. Thermocouples are measured
at 1 ms/channel in a system based on the
OMB-DBK90.
High-Isolation Voltage
and Thermocouple Measurements
The OMB-DAQSCAN can be combined with the
OMB-DBK207/CJC options to create an isolated
system capable of measuring up to 256 channels
of voltage, thermocouple, RTD and strain gage
inputs. All input channels can be scanned up to
200 kHz and are isolated by 500 V from other
channels and from system common. Any
combination of input signals is possible by
selecting the appropriate OM5 signal conditioning
module for the OMB-DBK207/CJC.
DaqView Software Real-Time Display
The 168 TC channel system consists of one
OMB-DAQSCAN-2005 plus three OMB-DK90
modules with rack-mount kits
OMB-DBK207/CJCs can be mounted at the
front or rear of the rack. They attach to the
OMB-DAQSCAN via a simple OMB-CA-37-10 cable.
C-2
The 24-channel isolated system includes an
OMB-DAQSCAN-2005 plus two OMB-DBK207/CJC
boards. The system is capable of scanning all
channel and provides 500 V isolated for all inputs

SM
Measurement System
The OMB-DAQSCAN-2005 can
be combined with OMB-DBK85
16-channel voltage input
modules to build a 5 µs/channel
voltage measurement system
with up to 256 channels. All
inputs can have a different
software programmable input
range, from 156 mV FS to 10 V
FS, programmable on a perchannel basis. The 16 BNC
inputs on the OMB-DBK85 can
be accessed from either the front
or the rear of a rack system.
The 80-channel high-speed scanning system consists of an
OMB-DAQSCAN-2005 plus five OMB-DBK85 16-channel
voltage scanning modules. All channels can be measured
at the maximum rate of 5 µs/channel
OMB-DAQSCAN-2005,
front and back, shown
smaller than actual size
Multifunction I/O System
All of the foregoing capabilities can be
combined into a single system using
one OMB-DAQSCAN-2001 as the
system centerpiece.
The system provides 56 non-isolated TC
inputs, 16 isolated voltage inputs, 4 analog
outputs, 4 frequency inputs and 32 isolated
discrete high-volage outputs.

TRIGGERING
Trigger Sources: 6, individually
selectable for starting and stopping
an acquisition. Stop acquisition can
occur on a different channel than
start acquisition; stop acquisition
can be triggered via modes 2, 4, 5
or 6, described below.
1. Single-Channel Analog
Hardware Trigger
Any analog input channel can be
software-programmed as the
analog trigger channel, including
any of the 256 analog expansion
channels.
2. Single-Channel Analog
Software Trigger
Any analog input channel, including
any of the 256 analog expansion
channels, can be selected as the
software trigger channel. If the
trigger channel involves a
calculation, such as temperature,
then the driver automatically
compensates for the delay
required to obtain the reading,
resulting in a maximum latency of
one scan period.
3. Single-Channel Digital Trigger
A separate digital input is provided
for digital-triggering.
4. Digital Pattern Triggering
8- or 16-bit pattern triggering on any
of the digital input ports.
Programmable for trigger on equal,
above, below, or within/outside of a
window. Individual bits can be
masked for “don’t care” condition.
5. Counter/Totalizer Triggering
Counter/totalizer inputs can trigger
an acquisition. User can select to
trigger on a frequency or on total
counts that are equal, above, below
or within/outside of a window.
6. Software Triggering
Trigger can be initiated under
program control.
