Measurement Computing 2000 Series Daqboar - Manual (Page 28)

1-2 Daq Systems and Device Overviews 10-18-02 DaqBoard/2000 Series & /2000c Series User’s Manual
In addition to the included out-of-the-box software, Daq products can be controlled via user-written
custom programs through Applications Program Interface (API). Several languages are supported,
e.g., C/C++, VisualBASIC, Delphi.
DaqView and DASYLab can only be used with one DaqBoard/2000 Series board or
/2000c Series board at a time. LabView can be used with multiple boards.
For multiple board use (via custom programming) refer to the
Using Multiple
Devices section of the Programmer’s Manual . During software installation from the
data acquisition CD (p/n 1022-0601), a PDF version of the Programmer’s Manual is
automatically loaded onto your hard drive as a part of product support. The
default location is the Programs directory.
Reference Note:
Programming topics are covered in the Programmer’s User Manual (p/n 1008-0901).
As a part of product support, this manual is automatically loaded onto your hard drive
during software installation. The default location is the Programs directory, which can
be accessed through the Windows Desktop.
DaqBooks, DaqBoards and Daq PC-Cards
Daq products connect to one or more DBKs on their signal input side and a computer on their output side.
Each type of Daq device connects to the computer in a different way:
• The DaqBook is an external module that connects to a computer’s enhanced parallel port (EPP)
interface or PC-Card link.
• The DaqBoard [ISA type] board is an internal card that plugs into an ISA-bus slot within a
computer.
• DaqBoard/2000 Series Boards plug into a PCI-bus slot, within a host PC.
• DaqBoard/2000c Series boards plug into a compact-PCI-bus slot, within a host PC.
• The Daq PC-Card slides into the PCMCIA slot of a host computer, typically a notebook PC.
Features common to the Daq products include:
• 100-kHz channel-to-channel scan and gain switching (10 µs);
200-kHz for DaqBoard/2000 Series and DaqBoard/2000c Series Boards.
• 512-location sequence memory that can be loaded with any combination of channels and gains.
• Ability to access up to 256 different channels of DBK signals while maintaining the channel-to-
channel scan rate. The DBK expansion options can accommodate mixed-signal inputs from
thermocouples and RTDs to isolated high-voltage inputs and strain gages.
• Ability to handle 8 differential or 16 single-ended signal inputs without DBK expansion units.
• Ability to handle fixed digital I/O up to 4 TTL lines in and 4 TTL lines out (accessible only if no
analog expansion cards are in use).
