 DaqLab/2000 
Series 
 
Each DaqScan/2000 Series model is packaged in 1U high (1.75”), 19” wide full-rack package, 
and includes a rackmount kit that can attach to either the front or the rear of the enclosure. 
Multiple DaqScan models can be combined in the same system.  Up to 4 units can be 
synchronized [scan synchronous post-trigger] via rear panel SYNC connectors. 
 
DaqScan/2000 Series devices include comprehensive drivers for popular Windows-based 
environments, including Visual Basic, C/C++, ActiveX/COM, LabVIEW, MATLAB, and DASYLab.   
The devices include DaqView, an interactive spreadsheet-style application that is ideal for 
verifying signal connections during system design. 
 
 
Reference Notes:  
¾  Block diagrams are presented in chapter 3.

Connectors and pinouts are discussed chapter 4.
 
Product Features 
•   Can be used to add 
analog I/O, digital I/O and frequency I/O to Ethernet-based test 
systems.  Each DaqScan/2000 Series device has a different combination of features 
(see comparison matrix on page 2-1). 
• 
All I/O can be synchronous, enabling precise timing between various I/O functions 
ƒ  Up to 4 units can be synchronized [scan synchronous post-trigger] via rear panel 
SYNC connectors. 
•  
8 differential, or 16 single-ended inputs, expandable up to 256 voltage or 896 TC 
channels using signal conditioning and expansion options 
•  
Up to 40 built-in TTL-level digital I/O, expandable up to 256 channels of isolated I/O 
using low-cost isolation modules 
•  Configuration through software only.  Device settings are made via software.  There 
are no hardware settings to be made, for example, there are no device DIP switches 
to be set or jumpers to be positioned.  However, note that DBK expansion options 
may require s small degree of manual set up.  Refer to the DBK Option Cards and 
Modules User’s Manual (457-0905) for details.  A PDF version of the document is 
included on the installation CD. 
• 
Includes support for Visual Basic®, C/C++, ActiveX/COM, LabVIEW®, MATLAB®, and 
DASYLab®
 
• 
Includes Out-of-the-Box™ DaqView™ software to facilitate signal and wiring 
verification with no programming required 
• 
Convenient 1U high (1.75”), 19” wide rack mount package minimizes rack space in 
test systems 
•  Four 16-bit counters. Each can accept frequency inputs up to 10 MHz. The counters 
can be cascaded into two 32-bit counters.  Counter connection is via a removable 
screw terminal block on the front panel.  
•  Two 16-bit timer outputs. Each can generate square waves from 16 Hz to 1 MHz.  
Connection to the timer outputs is via a removable screw terminal block on the front 
panel 
•   Scan Sequencing.  Each DaqLab/2000 Series device has a scan sequencer that can 
select up to 16384 channel/range combinations.  Scan rates are programmable on a 
per channel basis to 5 µs/channel, 10 µs/channel, or 1000 µs/channel. 
Note:   Inputs can be measured at the 5 µs/channel rate.  However, some DBK 
expansion options require more settling time and can be measured at the 
slower rate of 10 µs/channel or 1000 µs/channel.   All types of measurements 
can be mixed within the scan group.
