The LabJack U12 is a measurement and automation peripheral that enables the connection of a
PC to the real world. Although the LabJack U12 has many redundant protection mechanisms, it
is possible, in the case of improper and/or unreasonable use, to damage the LabJack and even
the PC to which it is connected. LabJack Corporation will not be liable for any such damage.
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 does not matter if the hardware or software is installed first.
If you experience installation problems on Windows 98 Second Edition, before contacting us,
please go to the downloads page at labjack.com and download “win98sehid.zip” (see the
readme file for more information).
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.
