Theory of Operation
for DaqBoard/2000 and /2000c Series Boards
As implied by the following matrix, the operational material does not apply globally to every
DaqBoard/2000 Series board or /2000c Series board. For example, boards /2002, /2003, /2004, and their
respective compact-PCI counterparts have no analog input.
For ease of understanding, each board is discussed independently, following the matrix. Note that pinouts
are provided in chapter 2.

versions)
Analog Input
Channels
Analog Input signals enter
through P4 , go to MUX, to
PGA, to Gain & Offset
Amplifier, then to Analog-
to-Digital Converter (ADC)
Analog Output
Channels
Digital Signals go through
Digital-to-Analog
Converters, then through
“DAC Out” on P4.
Digital I/O
Channels
Digital signals pass
through one 16-bit
Digital I/O Port and
three 8-bit Digital I/O
Ports located on P4.
Counter/
Timers
Four 16-bit Counter
Input signals and Two
16-bit Timer Output
signals via P4 and
System Controller.
