LabJack U12 Downloads

U12SetupV120a.exe: This is the legacy software installation for the LabJack U12. The directory and file structure has been changed since V1.17, so LabJack U12 software V1.17 or lower should be uninstalled first. If you are not sure what version you currently have installed, run LJtest and see if it reports driver version 1.17 or lower. LabJackUD does not support the U12, so this U12 specific driver should still be used. This install includes drivers, documentation, examples (LabVIEW), and sample applications. 05/30/2007, 17 MB, Windows 98SE/ME/2000/XP/Vista.
