UD Series Software Options
- Sample Applications: All free. LJControlPanel (part of the normal Windows installation) has a test panel where you can view all inputs and manually control all outputs. LJLogUD collects analog input data in command/response mode (generally 100 Hz or slower), displays it on screen, and writes it to file. LJStreamUD collects analog input data in stream mode (generally 10 Hz or faster), displays it on screen, and writes it to file. Both applications are free.
- Programming: All free. 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 UD Series Programming page.
- DAQFactory: Free and paid versions. DAQFactory is measurement and automation software from Azeotech, that allows non-programmers to make custom applications. Start on our DAQFactory page.
