DaqBooks, DaqBoards and Daq PC-Cards
Daq*s connect to one or more DBKs on their signal input side and a computer on their output side. Each
Daq type 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] is an internal card that plugs into an ISA-bus slot within a computer.
•
The DaqBoard/2000 Series boards plug into a PCI-bus slot within a computer.
•
The Daq PC-Card is inserted in the PCMCIA slot of a notebook computer.
Features common to the Daq*s include:
•
100-kHz channel-to-channel scan and gain switching (10 µs); 200-kHz for the DaqBoard/2000.
•
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).
Each type of Daq has several models to meet various needs. The table lists these models and their features.
