• DBK33 – For use with a Log Book, DaqBook, DaqBoard, or Daq PC-Card. It supplies +5 V and ±15 V.
• 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
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.
10 – Install DBK cards
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.
11 – Connect internal signals
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.
