1.2 - Software Installation [U12 Datasheet]

Although the low-level USB drivers for the LabJack are included with Windows, high-level drivers are needed to send and receive data. Get started by going to labjack.com/support/u12.

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 such as LJtest. If prompted to reboot after this installation, go ahead and do so. Virus scanners can often interfere with the installation of the LVRTE. If you have trouble running the example applications, repeat the LabJack software installation to make sure the LVRTE is installed.

To test the installation, start LJtest by selecting

Start → Programs → LabJack U12 Legacy → Legacy U12 Samples → LJtest.

Make sure “Test Fixture Installed” and “Continuous” are not selected, and press the “Run” button. LJtest will step through 14 separate tests and all should pass. The I/O tests assume nothing is connected to the U12 (except USB), so they will likely fail if you have any connections.
