Multiple Personal Daqs
Multiple modules can be operated synchronously. This is done by designating one as the master. The other
modules [slaves] are synchronized to the master by the pacer clock which is externally routed to the
designated slave units.
For two or more Personal Daqs to be operated synchronously:
(1) Use coax (or twisted-pair wire) to either (a) connect the APCR signals together,
or (b) connect the DPCR signals together.
(2) Connect Digital Common [of each Personal Daq] to one of the twisted pairs,
or to the shield of the coax.
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
Ready-to-use programs are convenient for fill-in-the-blank applications that do not require programming
for basic data acquisition and display:
• DaqView is a Windows-based program for basic set-up and data acquisition. DaqView lets you
select desired channels, gains, transducer types (including thermocouples), and a host of other
parameters with a click of a PC’s mouse. DaqView lets you stream data to disk and display data
in numerical or graphical formats. PostView is a post-acquisition waveform-display program
within DaqView.
• ViewXL/Plus allows you to interface directly with Microsoft Excel to enhance data handling and
display. Within Excel you have a full-featured Daq control panel and all the data display
capabilities of Excel.
• Post acquisition data analysis programs, e.g., PostView, DIAdem, and eZ-PostView, typically
allow you to view and edit post-acquisition data.
• The Daq Configuration control panel allows for interface configuration, testing, and
troubleshooting.
Each Daq system comes with an Application Programming Interface (API). API-language drivers include
C/C++ and Visual Basic. The latest software is a 32-bit version API.
