4 - LabJackUD High-Level Driver [U3 Datasheet]

LabJackUD is the high-level Windows driver for the U3, U6 and UE9. LabJackUD is also referred to as UD and LJUD.

For Linux or Mac OS X, use the Exodriver.

The low-level U6 functions are described in the low-level documentation, but most Windows applications will use the LabJackUD driver instead.

See the UD Library User's Guide. U3 specific pseudocode is available in Section 4.1.

Installation Details

The UD library is supported on Windows XP and newer. The archived 3.06 version supports Windows 98, ME, and 2000.

Please install the software before making a USB connection to a LabJack.

The download version of the installer consists of a single executable. This installer places the driver (LabJackUD.dll) in the Windows System directory, along with a support DLL (LabJackWUSB.dll). Generally this is:

  • Windows 98/ME:C:\Windows\System\

  • Windows 2000/XP and 32-bit Windows Vista/7/8/10:C:\Windows\System32\

  • 64-bit Windows Vista/7/8/10:C:\Windows\System32\ (64-bit drivers) C:\Windows\SysWOW64\ (32-bit drivers)

Other files, including the header and Visual C library file, are installed to the LabJack drivers directory. Defaults are:

  • 32-bit Windows:C:\Program Files\LabJack\Drivers\

  • 64-bit Windows:C:\Program Files (x86)\LabJack\Drivers\
