Analogue Inputs

The LabJack UE9 has 14 external analogue inputs (AIN0-AIN13) and 2 internal analogue inputs (AIN14-AIN15). AIN0-AIN3 are available on screw terminals and also on the DB37 connector. All 14 analogue inputs are available on the DB37 connector. The Mux80 multiplexer can expand this to to 80 single ended or 40 differential channels.

Each analogue input can be configured individually as unipolar (0-5 volts) or bipolar (±5 volts). An internal PGA provides gains of 1, 2, 4, or 8 (unipolar ranges only at this time). Analogue input resolution is 12-bits at max speed (10 us conversion time giving 50kHz rate), increasing up to 16-bits at slower speeds (10 ms conversion time).


It is possible to connect thermocouples directly to the UE9, if you don't require great accuracy: a resolution of ±1 °C is achievable. You need set the resolution to maximum (17 bits) and use the highest gain setting. The UE9 has an internal temperature sensor, which can be used for cold junction compensation. DAQFactory contains thermocouple linearisation as a built-in conversion function. A DAQFactory thermocouple example will be available shortly.

Analogue Outputs

The LabJack UE9 has 2 analogue outputs (DAC0 and DAC1) that are available both on screw terminals and the DB37 connector. Each analogue output can be set to a voltage between 0 and about 4.8 volts with 12-bits of resolution.

Digital I/O

The LabJack UE9 has 23 digital I/O channels which can be individually configured as input, output-high, or output-low. 8 of these lines are called flexible digital I/O (FIO) and can be software configured as up to 6 timers and 2 counters.

The first 4 FIO are available on screw terminals and the DB37 connector. All 8 FIO and 3 MIO are available on the DB37 connector, and 8 EIO and 3 CIO are available on the DB15 connector.

Up to 6 FIO can be configured as timers. The timers are very flexible, providing options such as PWM output for motor control, pulse timing, and quadrature input. Up to 2 FIO can be configured as 32-bit counters.



A Ready-to-run executable logs from 1-16 channels on a U3, U6, or UE9. Displays selected channels on a graph and writes data to file. Executable requires the LabVIEW 6.0 run time engine (which can coexist with other versions of the LVRTE).


For faster acquisitions use the ready-to-run executable which streams analog inputs from 1-16 channels on a U3, U6, or UE9. Displays selected channels on a graph and writes data to file. Executable requires the LabVIEW 6.0 run time engine (which can coexist with other versions of the LVRTE).


Supplied with LabVIEW VI's. These VIs make use of the native TCP capability of LabVIEW. They do not require any special LabJack drivers, and thus should work on any LabVIEW platform that supports TCP


If you know any language we probably support it. This includes C, C++, C#, Delphi, Java, LabVIEW, LabWindows/CVI, MATLAB, Python, and Visual Basic (VB6/VB.NET). Start on the UD Series Programming page.

DAQFactory Express

The free Express version of DAQFactory works with the U12. DAQFactory allows non-programmers to make custom applications. It is easy to collect input data, convert to engineering units, display it, and log it to file, without any programming. Scripting is also supported so you can do advanced applications with control and automatic setting of outputs.
