UD Series Software Options
- Sample Applications: LJControlPanel (part of the normal Windows installation) has a test panel where you can view all inputs and manually control all outputs. LJLogUD.exe collects analog input data in command/response mode, displays it on screen, and writes it to file. LJStreamUD.exe collects analog input data in stream mode, displays it on screen, and writes it to file.
- Programming: If you know any language we probably support it. This includes C, C++, C#, Delphi, Java, LabVIEW, LabWindows/CVI, MATLAB, Python, and Visual Basic (VB6/VB.NET). Start on our main support page.
- DAQFactory: DAQFactory is measurement and automation software from Azeotech. The Express version of DAQFactory is included with each U3/U6/UE9/U12. DAQFactory allows non-programmers to make custom applications. It is easy to collect input data, convert to engineering units, display it, and log it to file, without any programming (see the quick tutorial). Scripting is also supported so you can do advanced applications with control and automatic setting of outputs. Check out www.daqexpress.com, and on the UD downloads page check out the DAQFactory - LabJackUD Quick Tutorial and the DAQFactory - LabJackUD Application Guide.
- CloudDot: For applications at about 1 Hz or slower, our CloudDot system is a great way to do everything online. Get started for free at cloud.labjack.com.
All of these are free, at least to start. There are premium versions of DAQFactory and CloudDot available.

Thank you so much for your quick response. I was struggling with this late last night when I sent the request, and now first thing this morning I have a helpful reply. [...] By the way the upgrading process is so painless, it's fantastic! May I congratulate you on a well developed product with great product support.
