Timer Outputs
Two 16-bit timer outputs are built into every 3000 series board. Each timer is capable of generating a
different square wave with a programmable frequency in the range of 16 Hz to 1 MHz.
Example 6: Timer Outputs
Timer outputs are programmable square waves. The period of the square wave can be as short as 1us or as
along as 65535 us. See the table below for some examples.
Divisor Timer Output Frequency
1 1 MHz
100 10 kHz
1000 1 kHz
10000 100 Hz
65535 15.259 Hz
There are 2 timer outputs that can generate different square waves. The timer outputs can be updated
asynchronously at any time. Both timer outputs can also be updated during an acquisition as the result of
setpoints applied to analog or digital inputs. See the section on pattern detection setpoints for more
information and examples.
Multiple DaqBoards per PC
The features described for DaqBoard/3000 Series boards can be replicated up to four times, as up to four
boards can be installed in a single host PC. The serial number on each board differentiates one from
another, and a user-selected name can be assigned to each board for easy recognition within the program.
When multiple boards are installed they can be operated synchronously. This is done by designating one
board as the master. The other boards [slaves] are synchronized to the master by the pacer clock which is
externally routed to the designated slave boards.
Software
Included with the /3000 Series is a complete set of drivers and example programs for the most popular
programming languages and software packages. Driver support includes Visual Basic®, C/C++,
LabVIEW®, DASYLab®, and MATLAB®. DaqCOM™ provides Windows®-basedActiveX/COM-
based programming tools for Microsoft® VisualStudio® and VisualStudio.NET®. Also included with the
/3000 Series is new DaqView™ software, a comprehensive Out-of-the-Box™ application that enables set-
up, data logging, and real-time data viewing without existing programming skills. Optional DaqView/Pro
also adds features such as direct-to-Excel® enhancements, FFT analysis, statistics, etc. DaqView software
provides Out-of-the-Box™, quick and easy set up and collection of data.
Daq devices have software options capable of handling most applications. Three types of software are
available:
• ready-to-use graphical programs, e.g., DaqView, DaqViewXL, and post acquisition data analysis
programs such as PostView, DIAdem, and eZ-PostView
• drivers for third-party, icon-driven software such as DASYLab and LabView
• various language drivers to aid custom programming using API
