Reference Notes:

o In regard to calculating system power requirements, refer to DBK Basics located near
the front of this manual.

Overview
DBK11A is a passive card that provides screw-terminal connections and optional BNC connections inplace of a 37-pin (DB37) connector; i.e., P1, P2, or P3. In addition to providing access to all 37 pins on aDB37 connector, the card includes sockets for optional passive-filtering components.
In regard to the optional filtering aspect, the card provides connectivity between DB37 pins and screw
terminals while passing through the card’s prototyping area, as can be seen in the following figure. Thisregion of the DBK11A can accommodate resistors, capacitors, and custom wiring. The user can choose
component values to meet application requirements.

Note:

DBK11A is compatible with DB37 connectors, for example the P1, P2, and P3 connectors on
LogBook, DaqBook, and DaqBoard devices. The DBK11A card has footprints for 4 BNC
connectors that can be soldered onto the card.

Hardware Setup
DBK11A Connections
The DBK11A connects to a P1, P2, or P3 DB37 connector via a CA-37-x cable. The card has screwterminal blocks for easy access to analog inputs and outputs. Each screw-terminal has a numberthat corresponds to a pin number on the DB37 connector.
The DBK11A prototyping area, see figure, contains standard 0.1” hole spacing for the optional installationof user-customized circuitry.
BNC connectors can be soldered to the board at footprints labeled: CN0, CN1, CN2, and CN3. These will
have connectivity to J6 and J12, as indicated in the figure. The J6 and J12 terminals can be wired to theother screw terminals to provide BNC connection for designated P1 pins.

DBK11A Board Layout

Reference Notes:
Refer to chapter 2, System Connections and Pinouts, to verify the pin designations for P1, P2, or P3,
as applicable. The DBK11A screw-terminals are labeled 1 through 37. These numbers correspond
one-to-one with specific DB37 pins for P1, P2, and P3.
To make wire connections to the card’s terminal blocks:

DBK11A, pg. 2

1.

Refer to the applicable pinout (P1, P2, or P3) in chapter 2, System Connections and Pinouts.

2.

Using 14 to 26 gage signal wire, make the appropriate connections to the DBK11A terminal blocks.
The screw-terminal numbers 1 through 37 correspond directly with the P1, P2, or P3 pins, dependingon which DB37 connector applies.

3.

Once all connections have been made, secure all wires at the end of the DBK11A board. Nylon tiewraps (not included) work well for this purpose.

If you want to add your own custom circuit to the DBK11A:
The DBK11A includes spare terminals for optional circuitry, such as RC networks. The card includes
several hundred unconnected solder pads and signal paths to the analog input terminals [pins 11-18 and30-37]. Note that the default circuit path is just a straight connection, with no options.
Optional RC filters can be located on the card to correspond with the DB37 pins for the 16 analog input
channels. Before adding components, drill out the 1/16” diameter jumper-removal holes.

DaqBook and DaqBoard Configuration
Due to the DBK11A’s simplicity and flexibility, no configurations are required other than those that may
depend on the nature of the signal source.

CE Compliance
Reference Note:
Should your data acquisition system need to comply with CE standards, refer tothe CE Compliance section of chapter 1, Signal Management.

Software Setup
Reference Notes:
o DaqView users - Refer to chapter 3, DBK Setup in DaqView.
o LogView users - No Setup in LogView.

Note: DaqView Users – The DBK11A is not listed in DaqView’s Hardware Configuration window;
however, to use the card you must configure the applicable DBK11A channel(s) for Direct Signal
Connect. When you select Direct Signal Connect, the applicable channels are made available on
the DBK11A, from within DaqView. Note that aside from the ability to read Analog accessed
through P1, the digital I/O window of DaqView can access a DBK11A connected to P2; and thecounter/timer window can access a DBK11A connected to P3.
