Multifunction DAQ with WiFi, Ethernet, and USB

Choose the T7 series for ultimate flexibility. With 16 to 24-bit analog inputs, the option to use USB, Ethernet, or WIFI, and numerous built-in firmware features, the T7 Series can help you accomplish nearly any data acquisition need.

It's great for acquiring signals from virtually any kind sensor, and can serve that sensor data out through any of its 3 communication interfaces. With instrumentation amplified inputs, software selectable gain settings, dozens of digital I/O features, and a Modbus TCP front-end, the T7 Series is our most versatile multifunction DAQ platform. Common applications include laboratory research, industrial control and monitoring, and prototype development.  Additionally, the T7 series devices are capable of stand-alone operation by running Lua Scripts.

T7-Pro vs. T7

The T7-Pro has all the features of the normal T7 with the major addition of 802.11b/g WiFi connectivity and an auxiliary low-speed high-resolution (24-bit) sigma-delta ADC.

OEM Versions

The T7 and T7-Pro come in standard and OEM versions. The OEM versions are intended to be embedded in another device.  They are missing the enclosure and most connectors, as it is easier to install connectors than it is to remove them.  LabJack can customize the boards to add or remove hardware before shipping, for an additional fee. More information on OEM versions can be found in the OEM Versions section of the T7 Datasheet.

Other Highlights

  • Each purchase includes lifetime support
  • Actively monitored and highly informative forums where users can share ideas, ask questions, and get answers from both peers and our technical support staff
  • Free applications to configure, test, and log data to file
  • Free examples: C/C++, C#, Delphi, Java, LabVIEW, MATLAB, Python, VB.NET and more...
  • Modbus TCP – Use any platform that supports TCP/IP, no driver required
  • Free cross-platform LJM Library – Extends/wraps the Modbus protocol for convenience
  • Expansion boards – Add ±10V DACs, 4-20 mA inputs, terminal boards, relay boards and more...
  • This all sounds like what I need, but why LabJack?


Every feature of the T7 can be accessed directly using the associated Modbus TCP address, or use the LJM Library to access all features by name. This provides a powerful yet simple interface for almost any language or program.

Getting Started

1. Download and install the T7's installation package.
2. Connect the T7 to the computer via USB.
The T7's status LED should blink at power up and then stay solid on. If Windows asks about installing new hardware accept the defaults.
3. Run Kipling.
Kipling is a free application installed by the T7's installation package. You should be able to find it in the Start Menu links.

Go to the T7's Quickstart page for more detailed instructions.

T7 Applications

Kipling: T7/T7-Pro compatable USB, Ethernet, WiFi Configuration & Control Application


Kipling is an application that allows users to configure T7/T7-Pro devices, discover device features, write and upload Lua Scripts, and update their firmware.

LJLogM: T7/T7-Pro compatable USB, Ethernet, WiFi Data Logging Application


LJLogM is an application that allows data to be collected at variable rates from a T7/T7-Pro and saved to a .csv file. This logging program should be used when collecting data slower than 100Hz. Simple scaling equations can be used to apply mathematical filtering to the values before they are graphed & logged to a file.

LJStreamM: T7/T7-Pro compatable USB, Ethernet, WiFi Data Logging Application


LJStreamM is an application that uses the T7/T7-Pro's streaming functionality to collect data at high rates to graph and save the data to a .csv file. This logging program should be used when collecting data faster than 100Hz. Simple scaling equations can be used to apply mathematical filtering to the values before they are graphed & logged to a file.

T7 uSD Card Utility: T7/T7-Pro compatable USB, Ethernet, WiFi uSD File Downloading Utility

T7 uSD Card Utility

The T7 uSD Card utility is an application that connects to T7/T7-Pro devices to allow files saved to installed uSD cards to be downloaded with out having to remove the uSD card from the device. This allows files that were created by lua scripts to be downloaded.
