T4 Quickstart Tutorial

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

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".

Adjust the DAC0 analog output voltage, and you will see AIN0 follow DAC0 if the jumper wire is installed.

GND stands for Ground. Try connecting and disconnecting the FIO4 end of the jumper wire.

Digital inputs have an internal weak pull-up resistor that holds them high when nothing is connected. When the GND wire is connected to FIO4, the digital input will change from logic level High to logic level Low.

The FIO and EIO lines on the T4 can be configured as low voltage analog inputs.
