PC-Based, 16-Bit Data Acquisition with Expansion System
This guide primarily describes the system expansion capabilities of the DaqBook/260. For more information on
DaqBook issues, refer to chapter 2 in the DaqBook/DaqBoard/Daq PC-Card User’s Manual. For more information on
DBK cards, refer to chapter 5.
The DaqBook/260 is a combination of a DaqBook/200 and a DBK60 expansion chassis. The DaqBook sits on an
upper shelf within the enclosure. Below it a card drawer can hold three analog DBK cards and provide termination
panels with connectors for various sensors.
The front panel has male DB37 connectors for
system expansion via P1, P2, and P3. Above the
DB37 connectors, the DaqBook section includes a
power switch, a DIN-5 connector for power-in, a
DB25 connector for printer pass-through, a DB25 to
the PC’s parallel port, and LED status indicators for
power, buffer overload, P1-P2-P3 active, and A/D
active.
