Installation
To install the driver from source code, first unzip the contents of the Exodriver source code. Then run the following commands in a
terminal (replace <Exodriver-Source-Directory> with the directory you unzipped the Exodriver source code to):
cd <Exodriver-Source-Directory>
sudo ./install.sh
Follow the install script’s instructions to install the driver.
For more Exodriver installation information go to the Exodriver page at labjack.com/support/linux-and-mac-os-x-drivers. The
source code download’s README, INSTALL.Linux and INSTALL.MacOSX also provides more information. If you run into
problems, first take a look at the comments section of the Exodriver page as the issue may have been helped with previously.
After installation, to test your U3 connect it to your computer with a USB cable. The USB cable provides data and power. Build and
run one of the examples from the source code download. Alternatively, install LabJackPython (at
labjack.com/support/labjackpython) and run one of its examples.
