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 on the P1

interconnect board. ±15 V is controlled by the JP1 on the DaqBook/200 acquisition processor board.

JP2 on interconnect board – If +5 V will be supplied to DBK cards outside the chassis, install the JP2 jumper

on the P1 interconnect board (see previous figure).

JP1 on interconnect board – If +5 V will be supplied to DBK cards inside the chassis, install the JP1 jumper

on the P1 interconnect board (see previous figure).

JP1 on acquisition processor board – If using a DBK32A or DBK33 power card anywhere in the system,

remove the +15 V/-15 V jumpers from JP1 on the DaqBook/200 acquisition processor board. Refer to

Hardware Setup in the DBK32A or DBK33 section of the DBK options manual.

7 – Install a 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.

Carefully align the power card’s DB37 connector with a DB37 connector on the interconnect board and

gently press them together.

Mount the power card with two screws into the standoffs on the card drawer.

8 – Configure DaqBook/260

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 DBK options manual (p/n 457-0905) as needed.

10 – Install DBK cards

You must use all analog DBK cards in the DaqBook/260; or all digital DBK cards providing that a

factory modification is made to do so. At no time can you mix analog and digital cards in a

DaqBook/260.

Carefully align the DBK card’s DB37 connector with a DB37 connector on the interconnect board and gently

press them together (see previous figure).

Mount the DBK card with two screws into the standoffs on the card drawer.

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 the following figure). Refer to the DBK options manual (p/n 457-0905) as needed.

•

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

thermocouple type used.
