1 - Installation

Windows Installation Overview

The LJUD driver requires a PC running Windows. For other operating systems, go to labjack.com for available support. Software will be installed to the LabJack directory which defaults to c:\Program Files\LabJack\.

Install the software first: Go to labjack.com/support/ue9.

Connect the USB cable: (See Section 2.2 for Ethernet installation tips) The USB cable provides data and power. After the UD software installation is complete, connect the hardware and Windows should prompt with “Found New Hardware” and shortly after the Found New Hardware Wizard will open. When the Wizard appears allow Windows to install automatically by accepting all defaults.

Run LJControlPanel: From the Windows Start Menu, go to the LabJack group and run LJControlPanel. Click the “Find Devices” button, and an entry should appear for the connected UE9 showing the serial number. Click on the “USB – 1” entry below the serial number to bring up the UE9 configuration panel. Click on “Test” in the configuration panel to bring up the test panel where you can view and control the various I/O on the UE9.

If LJControlPanel does not find the UE9, check Windows Device Manager to see if the UE9 installed correctly. One way to get to the Device Manager is:

Start => Control Panel => System => Hardware => Device Manager

The entry for the UE9 should appear as in Figure 1-1. If it has a yellow caution symbol or exclamation point symbol, right-click and select “Uninstall” or “Remove”. Then disconnect and reconnect the UE9 and repeat the Found New Hardware Wizard as described above.

Linux and Mac OS X

The Exodriver is the native USB driver for Linux and Mac OS X. With it you can use low-level functions to interact with your UE9 over USB. A TCP interface is not included in the Exodriver, but most programming languages have a TCP library to use. We demonstrate low-level function usage over TCP using C/C++ in the examples at labjack.com/support/ue9/c-native-tcp-example. The LJUD driver, LJControlPanel and LJSelfUpgrade applications are not available for Linux or Mac OS X.

Download the Exodriver at labjack.com/support/software or labjack.com/support/linux-and-mac-os-x-drivers. For Mac OS X you can use the Mac Installer for installation, otherwise use the source code and install script.

Mac OS X Installer

Unzip the contents of Exodriver_NativeUSB_Setup.zip and run Exodriver_NativeUSB_Setup.pkg. Then follow the installer’s instructions to install the driver.

Source Code

Mac OS X Requirements

  • OS X 10.5 or newer
  • Xcode developer tools
  • libusb-1.0 library available at libusb.info

Linux Requirements

  • Linux kernel 2.6.28 or newer.
  • GNU C Compiler
  • libusb-1.0 library and development files (header files)

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 UE9 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.
