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.

Electrical Shock Hazard! To avoid injury or equipment damage, turn off power to all connected
equipment during setup.
Use ESD tools, containers, and procedures during setup of DBK cards. Electrostatic discharge can
damage some of the components.
To prevent pin damage, align DBK cards with the backplane DB37 connectors before gently
pressing them together.

5 – Determine power requirements
Depending on the power needs of your system’s DBK cards, you may need to add a power card. Refer to
Calculating Your Power Needs in chapter 5 of the DaqBook/DaqBoard/Daq PC-Card User’s Manual.
A. Use the
DBK Power Requirements Work Table
to calculate the power requirements of your system’s DBK
cards.
B. Use the
Available Power Chart
to determine your system’s power availability.
C. If the required power in step 5A is more than the available power in step 5B, you need an additional power
card. There are three auxiliary power supply cards:
• DBK32A – For use with a LogBook, DaqBook, or DaqBoard. It supplies ±15 V.
