The kuraCloud Desktop Application (KCDA) connects compatible PowerLab data acquisition units to Lt on a Windows computer. It runs in the background so you can record live data directly into a lesson in your web browser.
Install KCDA on the Windows computer connected to your PowerLab. Students record and analyse their data in Lt.
Download KCDA for Windows
Choose the installer that suits your setup. Administrator permissions are required to install KCDA.
- EXE installer: use this for a standard installation. An internet connection is required because the installer downloads its installation package.
- MSI installer: a packaged installer for IT teams deploying KCDA to managed computers. See the IT installation guide (PDF) for deployment and network configuration information.
Both download pages include release notes. Review these before installing or updating, particularly when deploying to a teaching laboratory.
KCDA is a Windows application. It is not available for macOS, ChromeOS, Android, iPadOS, or iOS. Data sampling in Lt is not currently supported on ChromeOS, Android, iPadOS, or iOS.
Using Lt LabStation?
These downloads are for browser-based Lt. Lt LabStation is a standalone Windows application with its own data service. It does not require a separate installation of KCDA or Lt Sampling.
Start recording with your PowerLab
- Install KCDA. Complete the installation on the Windows computer connected to your PowerLab. Ask your IT team for help if you do not have installation permissions.
- Connect your hardware. Connect the transducers required by your lesson to the PowerLab. Connect the PowerLab to the computer by USB and turn it on.
- Open your lesson in Lt. Go to the page containing the configured Data Sampling or Scope Sampling panel.
- Follow the lesson instructions and select Start. Keep the PowerLab connected while recording.
Lt requires an internet connection. Your computer, browser, and hardware must meet the Lt system requirements. Check the hardware compatibility guide for supported PowerLab models.
Using PowerLab Sensors?
For compatible PowerLab Sensors, use the Lt Sampling app, available for Mac and Windows. Follow that page's instructions to install the app and enable it for your course.
KCDA and Lt Sampling can be installed on the same Windows computer. With current versions of both applications installed, KCDA handles compatible PowerLab data acquisition units and Lt Sampling handles compatible sensors. Restart the applications after installation or updating if your devices are not detected.
Keep KCDA up to date
Use the latest released version of KCDA. Updates can include compatibility fixes and security certificates needed for communication between Lt and the app.
Automatic updates may be managed by your organisation. If updates are restricted, ask your IT team to review the current release notes and any required update deadlines before teaching begins.
Do I need to uninstall before updating? Follow the instructions for the release you are installing. Some upgrade paths require older versions to be removed. Uninstall and reinstall when the release instructions or Technical Support direct you to do so.
If Lt cannot detect your PowerLab
- Check that KCDA is installed and running on the same Windows computer as your browser.
- Check that the PowerLab is connected by USB and turned on.
- Close other applications that may be using the PowerLab.
- Check the KCDA download page for required updates, then restart KCDA and refresh the lesson.
- If your browser asks you to allow Lt to connect to local devices or apps, follow the browser connection troubleshooting guide.
On managed computers, ask your IT team to check that the required KCDA services and network connections are allowed. The IT installation guide (PDF) provides configuration details.
If the issue continues, contact ADInstruments Technical Support. Include the KCDA version, Windows version, browser, PowerLab model, and any error message.
