Reference Notes: During software installation, Adobe ® PDF versions of user manuals will
automatically install onto your hard drive as a part of product support. The default location
is in the Programs group, which can be accessed from the Windows Desktop. Refer to the
PDF documentation, especially the DBK Option Cards and Modules User’s Manual
(p/n 457-0905) for details regarding both hardware and software in relevant to DBKs.
A copy of the Adobe Acrobat Reader ® is included on your CD. The Acrobat Reader
provides a means of reading and printing the PDF documents. Note that hardcopy versions
of the manuals can be ordered from the factory.
How Do DBKs Connect to the Data Acquisition Device?
Each DBK connects to the primary data acquisition device; e.g., a DaqBook, DaqBoard, or LogBook,
through one of three 37-pin ports, which are designated as follows:
• P1 – Analog I/O
• P2 – Digital I/O
• P3 – Pulse/Frequency/High-Speed Digital I/O
Depending on the primary data acquisition device, connectivity issues differ slightly. This will be made
clear by the figures and accompanying text that follow.

Reference Notes:
o
DaqBoard/2000 Series and /2000c Series users, refer to page 4.
o
DaqBook/2000 Series users, refer to page 5.
For DaqBook/100 Series and DaqBook/200 Series devices, ISA-Type DaqBoards, and LogBooks, DBK
connections are not made directly to the port, but through a CA-37-x ribbon cable, where “x” indicates the
number of expansion devices that can be connected. For example, in addition to providing a DB37
connector to interface with the primary data acquisition device, a CA-37-3 cable includes three additional
DB37 connectors. These provide a means of adding three DBKs to one port. Use of a CA-37-16 cable will
allow up to 16 DBKs to be added. The CA-37-x cable system is excellent for DaqBooks, LogBooks, and
ISA-type DaqBoards.
