T4 Quickstart Overview
The installer covers UD devices (U3, U6, UE9) and LJM devices (T-series, Digit), so not all installed applications will work with the T4. The following applications work with the T4:
- Kipling,
- LJLogM, and
- LJStreamM.
Only run 1 application at a time.
If there is an installation problem, see the Windows Installer Troubleshooting (App Note)

The status LED should blink at power up and then stay solid on to indicate successful enumeration.
If Windows asks about installing new hardware accept the defaults.
If the device does not enumerate see item F on the USB Communication Failure App Note.

Kipling is a free LabJack application installed along with the driver. To start it:
- Windows: You should be able to find it in the Start Menu links.
- Mac: Kipling.app in the Applications folder
- Linux: Open a terminal and execute the command labjack_kipling
7. Connect a jumper wire securely from DAC0 to AIN0.

For a guaranteed valid connection, a conductor must be clamped in the screw-terminal, not just touching some part of the screw-terminal.
DAC stands for "Digital to Analog Converter", AIN stands for "Analog Input".
