LabJack Software

NOTE:  All executable files are stored in our web site as .exx files.  After downloading, simply rename the file extension to filename.exe and run as normal.

LabJackV103.exx: Now supports Windows XP. This is the complete software installation for the LabJack U12. It includes drivers, examples, and sample applications. V1.03, 9/19/2001, 13 MB, Windows 98SE/ME/2000/XP. 

LabJackV103_driversonly.exe: Now supports Windows XP. For those without a high-speed Internet connection, this file installs only the driver DLL, ActiveX wrapper, and LabVIEW6 VIs. V1.03, 9/19/2001, 439 KB, Windows 98SE/ME/2000/XP. The normal LabJack installation includes a VI library for LabVIEW6, but since many people still use LabVIEW 5.1, the LabJack VIs have been reverted in this library. 8/15/2001, 416 KB.

VBSimple: A very simple example of a Visual Basic program that uses the ActiveX LabJack drivers component. 9/5/2001, 5 KB.

LJConsole: A very simple example of a Visual C console (DOS) program that calls a function from the LabJack DLL. 9/5/2001, 35 KB.

LabVIEW Miscellaneous Utilities

LJ Clock : Uses the combined values of "Get Date/Time In Seconds" and "Tick Count (ms)" to determine the absolute time (with milliseconds) since midnight on January 1, 1904. 8/27/2001, LabVIEW 6.0.2

Quit LabVIEW if Executable: A minor modification of "Quit" which only exits if called as part of an executable program. This is useful so that when running a VI in the development environment, LabVIEW will not shut down every time the VI is stopped. 6/17/2001, LabVIEW 6.0.2

Sort 2D: This is a nifty little VI which can be used to perform a cascading multi-column sort on a 2-dimensional array of alphanumeric values. 5/30/2001, LabVIEW 6.0.2

NickClick: How about a $25 PC/LabVIEW based image processing platform. Here are VIs to aquire and download images with an inexpensive Nick Click digital camera. 11/30/2000, LabVIEW 6

1wweather - LabVIEW drivers for the iButton Dallas Semiconductor 1-Wire Weather Station which provides real-time weather for LabJack Corporation. Includes standalone drivers for the DS1820 1-Wire temperature sensor and DS2423 1-Wire counter. This download includes the DLL, all source code, example VIs, and the Visual C project.
