DBK Basics
This “DBK Basics” section of the manual does not apply to DaqBoard/500 Series or DaqBoard/1000
Series boards. Those boards are not intended for use with DBK options; nor will they support such
options.

CAUTION
Turn off power to all devices connected to the system before connecting cables or
setting configuration jumpers and switches. Electrical shock or damage to
equipment can result even under low-voltage conditions.
CAUTION
The discharge of static electricity can damage some electronic components.
Semiconductor devices are especially susceptible to ESD damage. You should
always handle components carefully, and you should never touch connector pins or
circuit components unless you are following ESD guidelines in an appropriate ESD
controlled area. Such guidelines include the use of properly grounded mats and
wrist straps, ESD bags and cartons, and related procedures.
Introduction
The term “DBK” typically refers to a card or module that is used to expand or enhance a primary data
acquisition device, such as a DaqBook, DaqBoard, or LogBook. As will be seen in the upcoming DBK
identification tables, DBKs provide a wide variety of data acquisition functions. Depending on the DBKs
used, one or more of the following can be realized:
• signal conditioning
• analog output
• digital I/O
• channel expansion
• supplying powering to another acquisition device
• providing an interface for different connectivity; for example, in a DaqBoard/2000 Series board,
converting a P4, 100-pin connector to P1, P2, and P3 37-pin, DB37 connectors.
