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

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