LV-Link 3.0

Data Translation announces the release of a new version of its LV-Link software drivers for LabVIEW. LV-Link is a library of Virtual Instruments (VIs) that provide quick and easy access to Data Translation's USB modules and PCI boards in LabVIEW. Both the 32- and 64-bit versions of the graphical programming environment are supported. LV-Link 3.0 also includes a comprehensive, updated Help and additional example programs to facilitate application development.

The virtual instruments have been specially developed for high-speed data acquisition and output. They integrate all the subsystems and features provided by Data Translation's USB and PCI measurement hardware, including analogue I/O, digital I/O, counter/timers, quadrature decoders and streaming data to disk at full speed.

The use of polymorphic VIs allows a significant reduction in the number of virtual instruments within a LabVIEW application. Polymorphic VIs combine the functionality of different VIs into one VI that takes on different characteristics depending on the selected subsystem.

The software drivers are based on the DT-Open Layers .NET class library and are compatible with NI virtual instruments. LV-Link 3.0 supports LabVIEW 8.5.1 or higher and LabVIEW 2009 or higher. The previous LV-Link Version 2.0 is available for users of earlier LabVIEW releases. Both LV-Link versions are provided free to users of Data Translation data acquisition hardware and can be downloaded from the company’s website.
