Overview
The DBK213 module is compatible with the following products:
• DaqBook/2000 Series • DaqBoard/2000 Series • DaqLab • DaqScan
The DBK213 module includes:
o P1, male DB37 connector for Analog I/O.
o P2, male DB37 connector for Digital I/O.
o P3, male DB37 connector for Pulse/Frequency (Digital and Counter/Timer) I/O.
o P4, 100-pin connector. Provides same signal connection as P1, P2, and P3 combined.
o Three slots for housing optional DBK cards. The DB37 connector of each card will extend out
through the rear panel where it can be secured with hex nuts.
o 12 on-board screw-terminal blocks (accessible after removal of cover)
o The terminal blocks [TB1 through TB12] tie in to P1, P2, P3, and P4 and provide for easy signal
connection.
o Three front panel slots for wiring pass-through.
o On-board socket locations for custom RC Filter networks (accessible after removal of cover).
DBK213 Front Panel
Upper Slots for Terminal Board Wiring Pass-Through
Lower Slots for Housing up to 3 DBK options, 1 per slot
DBK213 Rear Panel
The upper section includes P1, P2, P3 and P4 connectors. The lower section
has 3 openings for pass-through of DB37 connectors from optional DBK cards.
The three DB37 connectors can be used as direct connections points for I/O signals, or signals can be
connected to each 37-pin connector via a DBK card or module. The lower section of the DBK213 includes
three built-in expansion slots for housing card options.
The unit includes screw-terminal access to all analog and digital I/O from the host data acquisition device.
Related to the screw-terminals are 3 front panel upper slots for routing all I/O wiring.

Connection Tips
CAUTION
Turn off power to the host PC and externally connected equipment prior to connecting
cables or signal lines to DBKs. Electric shock or damage to equipment can result even
under low-voltage conditions.
Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)
Use care to avoid touching board surfaces and onboard components. Only handle
boards by their edges (or ORBs, if applicable). Ensure boards do not come into
contact with foreign elements such as oils, water, and industrial particulate.
Do not confuse connectors. Ensure that you only connect P1 I/Os to P1, P2 I/Os to P2,
and P3 I/Os to P3. Improper connection may result in equipment damage.
When using P4, e.g., for a DaqBoard/2000, be sure to align the P4 orientation
indicators [white arrows] prior to mating the P4 connectors.
1. Ensure power is removed from the device(s) to be connected.
2. Observe ESD precautions when handling the board and making connections.
3. Do not make redundant connections. For example, for ANALOG IN you could use
the P1 (DB37) connector or Terminal Blocks TB9 through TB12. You would not use both
sets of ANALOG IN connectors.
4. You do not need to remove the cover unless you need to access a terminal block or customize
an RC filter network. Information regarding both tasks follows shortly. Note that RC filter
networks are not to be made or used in association with additional DBK expansion options.
5. DBK213’s 100-pin P4 connects to a DaqBoard/2000 Series board’s P4 via a CA-195
one-hundred conductor ribbon cable.
The DaqBoard/2000 Series boards communicate [external from the host
PC] through a 100-pin P4 connector. The P1, P2, and P3 connectors
discussed in association with these boards are subset connectors of the 100pin P4 connector. The System Connections and Pinouts chapters of the
product hardware manuals include pinouts.
6. Connections to the DB37 connectors are made via CA-37 cables or CA-255 cables:
(a) P1 connects to an analog DBK card or module’s P1 connector.
(b) P2 connects to a Digital DBK card or module’s P2 connector.
(c) P3 connects to a Pulse/Frequency DBK card module’s P3 connector.
7. Refer to the separate CE Cable Kit instructions that are included with the associated
CE cable kit.

The DBK213 has three card slots which allow for the easy installation of DBK cards. To install a card
observe the following CAUTION and then complete the few simple steps.
Beneath
P2
Turn off power to the host PC and externally connected equipment prior to connecting
cables or signal lines to DBKs. Electric shock or damage to equipment can result even
under low-voltage conditions.
Take ESD precautions (packaging, proper handling, grounded wrist strap, etc.)
Use care to avoid touching board surfaces and onboard components. Only handle
boards by their edges (or ORBs, if applicable). Ensure boards do not come into

CAUTION
1. Refer to your specific DBK card instructions prior to installing the card. You may need to make
physical hardware configurations, for example, regarding channel assignments.
2. Complete all DBK card configuration per your application and channel assignment needs.
3. Make signal line connections on your DBK card as applicable. Screw-terminal connections and BNC
connections are typical.
4. If hex nuts are present on your DBK card’s DB37 connector, remove them and put them aside for
reuse in step 7.
5. Using the lower card-edge-guide on the DBK213 front panel [and possibly the upper guide for high
cards such as the DBK82], carefully slide the card into the desired slot such that the card’s DB37
connector goes to the rear panel of the DBK213. The following should be considered when choosing
a card slot.
o Analog I/O cards will connect to the DBK213’s P1 male DB37 connector.
o Digital I/O cards will connect to the DBK213’s P2 male DB37 connector.
o Pulse/Frequency (Digital and Counter/Timer) I/O will connect to the DBK213’s P3
male DB37 connector.
6. Push the DBK card until its DB37 connector extends through the rear panel of the DBK213.
7. Using the hex nuts removed in step 4 (or replacement hex nuts if needed), secure the card at the rear
panel. Tighten the hex nuts snug, but do not over tighten.
8. Repeat these steps for each remaining card.

System Examples
Example 1:
DaqBoard/2000 • DBK7 Analog I/O Card • DBK25 Digital I/O Card
Notes regarding the above system example:
1) A CA-195 100-conductor ribbon cable connects the P4 connector of the DBK213 to the P4 connector of the
DaqBoard/2000 (which is installed in the host PC).
2) In the illustration, DBK213 is housing a DBK7 (Analog I/O card) and a DBK25 (Digital I/O card).
3) A CA-255 [or CA-37] cable is used to connect the DBK7’s DB37 P1 connector to the DBK213’s P1 connector.
4) A CA-255 [or CA-37] cable is used to connect the DBK25’s DB37 P2 connector to the DBK213’s P2 connector.

Example 2:
DaqBoook/2001 • DBK7 • DBK80 • DBK82
-------- (3 Analog I/O Cards)---------
Notes regarding the above system example:
1) Either of two Ethernet cables can be used: CA-242 is a 1.5 ft cable; CA-242-7 is a 7 ft. cable.
2) In the illustration, DBK213 is housing a DBK7, DBK80, and DBK82. Each is an analog card that will make use of P1
in regard to analog signal I/O.

to the P1 connector of the DaqBook/2001.
5) The DBK213’s P1 connector [rear panel, upper-left] connects to the internal screw-terminal board to which analog I/O
signals could be connected via wire. The wires would be routed out through the upper slots of the front panel.
6) A CA-255 [or CA-37] cable is used to connect the DBK213’s P2 connector to the DaqBook/2001 P2 connector.
7) The DBK213’s P2 connector connects to the internal screw-terminal board, to which digital I/O signals could be
connected via wire. The wires would be routed out through the upper slots of the front panel.
8) In a different scenario, the DBK213’s P2 connector could be connected to digital DBK options instead of connecting
the P1 connector to analog DBK options as illustrated.
