system components provide analog, digital,
and frequency I/O capability for Ethernetbased test systems. The DaqScan Series builds
on IOtech’s IEEE 488-based predecessors.
All DaqScan models are packaged in 1U highfull-rack package, and include a rack-mount
kit that can attach to either the front or
the rear of the enclosure. M­ ultiple DaqScan models can be combined in the same
system and synchronized using a simpleSYNC connection between units. All I/O isaccessed via male DB37 connectors locatedon the rear of the unit, making cabling easy
from the DaqScan to your device under test.
Two models in the DaqScan Series areavailable, and include the full-featured
DaqScan/2001 which provides 16 analog
inputs, 4 a­ nalog outputs, 40 digital I/O,
4 frequency i­nputs, and 2 timer outputs.

1The DaqScan includes comprehensive
drivers for all popular Windows-based
environments, including DASYLab,NI LabVIEW, Visual C++, Visual C#,
Visual Basic, and Visual Basic .NET. Also
included with the DaqScan is DaqView,
an interactive spreadsheet-style software
application that is ideal for verifying signal
connections during system integration.
The DaqScan/2000 Series has the same s­ ignal
I/O, synchronous scanning, t­riggering,and signal expansion capability as our­DaqBook/2000 Series. The compact 1U high19” rack packaging of the DaqScan make it acompact ­component for rack-based s­ ystems.
In addition to the built-in I/O provided by
the DaqScan/2000 Series, a wide variety ofsignal conditioning and expansion options
are available. The following page features
sample systems that can be derived fromthe DaqScan along with DBK options.

General Information

High-Channel Count
Thermocouple Measurements

The 168 TC channel system
consists of one DaqScan/2005
plus three DBK90 modules
with rack-mount kits

When combined with the DBK90 thermocouple input module, the DaqScan canmeasure up to 896 channels of TC input.
In the example system to the right, any
TC type can be installed into any channel using standard mini TC connectors.
Each 56 channel 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 TC conversion algorithms
built into the software make temperature
measurements easy. Thermocouples aremeasured at 1 ms/channel in a system
based on the DBK90.

High-Isolation Voltage &Thermocouple Measurements

The 32-channel isolated
system includes a
DaqScan/2005 plus two
DBK207/CJC boards. The
system is capable of scanningall channels at 5 µsec perchannel, and provides
500V isolation for all inputs.

The DaqScan can be combined with
DBK207/CJC options to create an isolated system capable of measuring up to256 channels of voltage, thermocouple, RTD
and strain gage inputs. All input channels
can be scanned up to 200 kHz, and areisolated by 500V from other channels andfrom system common. Any combination ofinput signals are possible by selecting theappropriate 5B signal conditioning module
for the DBK207/CJC. DBK207/CJCs can bemounted in the front or rear of the rack,and attach to the DaqScan via a simple
CA-37-x cable.

Isolated Digital I/O System

The 64-channel isolated
discrete I/O system consistsof one DaqScan plus two
DBK210 boards withrack-mount kits

When a DaqScan/2002 is combined with
the DBK208 or DBK210 options, up to256 channels of isolated digital I/O arepossible, capable of controlling AC or DC
voltages up to 250V, or sensing the presence of AC or DC voltages. All channels
are isolated from one another and fromthe system by up to 500V. Inputs can bescanned in 16-bit increments at speeds
up to 200 Kreadings/s. The DBK208 andDBK210 can be mounted in the front orrear of the rack.

Input Sequencer

Analog Output (Model /2001)

Analog, digital, and frequency inputs can be scanned
synchronously, based on either an internal­programmable timer, or an external clock source.
Scan Clock Sources: 2
1. Internal, programmable from 5 µs to 5.96 hours
in 1 µs steps
2. External, TTL level input up to 200 kHz maxProgrammable Parameters per Scan: Channel(random order), gain, unipolar/bipolar
Depth: 16,384 locations
On-Board Channel-to-Channel Scan Rate: 5 or 10 µs
per channel, programmable
Expansion Channel Scan Rate: 5 µs, 10 µs, or 1000 µs
per channel, programmable

The four analog output channels are updated synchronously relative to scanned inputs, and clocked fromeither an internal onboard clock, or an external
clock source. Analog outputs can also be updated
asynchronously, independent of any other scanningin the system.

Triggering
Trigger Sources: 6, individually selectable for startingand stopping an acquisition. Stop acquisition canoccur 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 the256 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 thesoftware trigger channel. If the trigger channel
involves a calculation, such as temperature, thenthe 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 t­ riggering.

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.

Digital I/O
Channels: 40, expandable up to 272 with external
digital DBK options
Input Scanning Modes: 2
1. Asynchronous, under program control at any
time relative to input scanning
2. Synchronous with input scanning
