1-2 Overview 02-13-02 Daq Systems
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.
•
cPCI DaqBoard/2000c Series boards plug into a cPCI-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).
The following table lists various features of DaqBooks, ISA-DaqBoards, and Daq PC-Cards. Note that
PCI and cPCI-type DaqBoards (the DaqBoard/2000 Series and DaqBoard/2000c Series Boards) are
covered in separate documentation.
