1. Installation
The LabJack U12 requires a PC running Windows 98SE, ME, 2000, or XP. To determine your
operating system version, go to
Start => Settings => Control Panel => System => General
and make sure the version number is 4.10.2222 or higher (Win98SE=4.10.2222,
WinME=4.90.3000, Win2000=5.0.2195, WinXP=5.1.XXXX).
It doesn’t matter if the hardware or software is installed first.
1.1 Hardware Installation
With the PC on and using the included cable, connect the LabJack U12 to the USB port on the
PC or USB hub. The USB cable provides power and communication for the LabJack U12. The
status LED should immediately blink 4 times (at about 4 Hz), and then stay off while the
LabJack enumerates.
Enumeration is the process where the PC’s operating system gathers information from a USB
device that describes it and it’s capabilities. The low-level drivers for the LabJack U12 come
with Windows and enumeration will proceed automatically. The first time a device is
enumerated on a particular PC, it can take a minute or two, and Windows might prompt you
about installing drivers. Accept all the defaults at the Windows prompts, and reboot the PC if
asked to do so. Enumeration occurs whenever the USB cable is connected, and only takes a
few seconds after the first time.
When enumeration is complete, the LED will blink twice and remain on. This means Windows
has enumerated the LabJack properly.
If the LabJack fails to enumerate:
•
Make sure you are running Windows OS version 4.10.2222 or higher,
•
Try connecting the LabJack to another PC,
•
Try connecting a different USB device to the PC,
•
Contact LabJack at

1.2 Software Installation
Although, the low-level USB drivers for the LabJack are included with Windows, high-level
drivers are needed to send and receive data. The included LabJack CD installs the high-level
drivers, example source code, and example applications.
Close all open applications, especially LabJack related software, and insert the LabJack CD. If
autorun is enabled, the installation program should start automatically. If the installation does
not start, you will have to manually double-click on LabJackVXXX.exe.
When the LabJack installation is finished, it will start the National Instruments LabVIEW Run-
Time Engine (LVRTE) setup. The LVRTE is required for the example applications: LJconfig,
LJlogger, LJscope, and LJtest. If prompted to reboot after this installation, go ahead and do so.
