DaqBook/260 User's Guide
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.

Hardware Setup
1 – Turn off system power and disconnect DaqBook/260
If the DaqBook/260 is presently connected in a system, turn off all system devices and disconnect it.
2 – Remove top cover
Remove the two top cover screws and slide off the top cover (see figure). DaqBook jumpers are now accessible.
3 – Remove card drawer
A. Remove the two screws holding the card drawer to the chassis (see figure).
B. Loosen the three captive thumbscrews holding the termination panels to the chassis (see figure).
C. Using the handle, carefully slide out the card drawer.
4 – Remove termination panels
Remove the two screws mounting each termination panel to the card drawer (see figure).

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.
2 DaqBook/260 User's Guide p/n 1034-0902 rev 2.0
• DBK33 – For use with a Log Book, DaqBook, DaqBoard, or Daq PC-Card. It supplies +5 V and ±15 V.
y
(-)
gh (+)
y
• CDK10 – For use with a Daq PC-Card. It supplies +5 V and ±15 V. The power source is housed in its
own expansion chassis.
6 – Configure chassis for power sources
Avoid having more than one power source on the P1 bus. +5 V is controlled by the JP1 and JP2 jumpers inside
the chassis. ±15 V is controlled by the JP1 jumpers on the acquisition processor.
A. If +5 V will be supplied to DBK cards outside the chassis, install the JP2 jumper on the P1 interconnect board
(see figure).
B. If +5 V will be supplied to DBK cards inside the chassis, install the JP1 jumper on the P1 interconnect board
(see figure).
C. If using a DBK32A or DBK33 power card anywhere in the system, remove the +15 V/-15 V jumpers from
JP1 on the acquisition processor board. Refer to
Hardware Setup
in the DBK32A or DBK33 section of the
DaqBook/DaqBoard/Daq PC-Card User’s Manual.
7 – Install power card if necessary
If you determined in step 5 that additional power is needed, add a DBK32A or DBK33 power card to the chassis.
(The CDK10 power card is housed in its own chassis.)
A. Carefully align the power card’s DB37 connector with a DB37 connector on the interconnect board and
gently press them together (see figure).
B. Mount the power card with two screws into the standoffs on the card drawer (see figure).
8 – Configure DaqBook/260
Refer to chapter 2 of the DaqBook/DaqBoard/Daq PC-Card User’s Manual. If a DaqBook/260 driver is not
available in software, select DaqBook/200.
9 – Configure DBK cards
10 – Install DBK cards
11 – Connect internal signals
BNC Connecto r
Termination Panel
()internal side
Configure unique channel addresses with the jumpers on the DBK cards. Some cards have other jumpers and/or
DIP switches. Refer to the particular DBK sections of the DaqBook/DaqBoard/Daq PC-Card User’s Manual.
You must use all analog DBK cards in the DaqBook/260. (A factory modification is available to use all digital
cards.)
A. Carefully align the DBK card’s DB37 connector with a DB37 connector on the interconnect board and gently
press them together (see figure).
B. Mount the DBK card with two screws into the standoffs on the card drawer (see figure).
C. Continue installation of any remaining DBK cards.
Connect signal inputs from DBK cards to termination panels. DBK cards connect to the termination panels in
various ways (see figure and particular DBK sections in manual):
•
Single-ended connections use analog common.
•
Differential connections require the proper polarity, typically red-to-red for high (+) and black-to-black for
low (-).
• For thermocouples, red is generally the low side, and the T/C connector and wire type must match the T/C
type used.

Mount the termination panels to the card drawer with two screws for each panel (see figure).
13 – Install card drawer
The card drawer slides into the bottom track of the chassis.
A. Hold the card drawer by its handle and tilt it up slightly. Place it on the bottom track of the chassis.
B. Carefully slide the card drawer into the chassis. When it engages the bottom track, level the card drawer and
continue inserting it until it engages with the P1 interconnect board.
C. Tighten the three captive thumbscrews holding the termination panels to the chassis (see figure).
D. Install the two screws holding the card drawer to the chassis (see figure).
14 – Connect external signals
Connect signal inputs from sensors to termination panels.
15 – Install top cover
Slide on the top cover and install the two top cover screws (see figure).
