  6. Click Start. Let it log for 5 minutes.
  7. Click Stop and then Download Data.

Software Functionality Review

Once the "fix" is applied and the connection is established, how does the software perform?

Interface: The interface is utilitarian and dated. It resembles Windows 98-era software. It is not intuitive; users must navigate through tabs like "Parameter," "Data," and "Export."

Key Features:

  • Parameter Setup: You can easily set the logging interval (from seconds to hours), alarm thresholds (high/low), and start modes (immediate or scheduled).
  • Data Download: Downloading logs is generally fast via USB. The data is presented in a graph format and a table format.
  • Export Options: The software allows exports to PDF, Excel (.xls), and Text (.txt). This is the strongest feature, as it allows for further analysis in proper tools like Excel.
  • Real-time Monitoring: The software allows for "Real-time" monitoring where the PC acts as the screen. This is useful for lab setups but requires the device to remain tethered.

Step-by-step driver fix:

  1. Download official CP210x driver
    Go to silabs.com/developers/usb-to-uart-bridge-vcp-drivers → Download the CP210x Windows Universal Driver (supports Win 7/8/10/11).

  2. Remove old/corrupt driver

    • Open Device Manager (Win+X → M).
    • Expand Ports (COM & LPT). If you see “CEM DT-172” or “CP210x” with a yellow triangle, right-click → Uninstall device → check “Delete driver software”.
    • Also check Universal Serial Bus controllers for any unknown device.

  3. Install fresh driver
    Run the downloaded .exe (Silicon Labs installer). Restart your PC.

  4. Reconnect DT-172
    Use a data-capable USB cable (not just a charging cable). Try a USB 2.0 port directly on the motherboard (avoid USB 3.0 hubs).

  5. Verify COM port
    In Device Manager → Ports, you should see “Silicon Labs CP210x USB to UART Bridge (COMx)”. Note the COM number.

2. Troubleshooting Common Download Issues

  • Slow or Interrupted Downloads: Ensure your internet connection is stable. If the download process is frequently interrupted, try using a download manager.
  • Compatibility Issues: Make sure you're downloading the software compatible with your computer's operating system (Windows, macOS, etc.).
