Safely eject/unmount the USB drive from your operating system to ensure data integrity. Step 4: Complete the Installation Process
If you bought a rebranded unit (e.g., "Velleman HPS2102S" or "SeeSii"), . You must get the update from your specific vendor. Using the wrong vendor’s firmware will corrupt the display controller.
Power it back on. The device will detect the file, perform the upgrade, and shut down automatically once finished.
The primary purpose of firmware updates is to fix specific bugs and improve stability. OWON has addressed certain issues in later revisions — for example, bugs related to frequency measurement in “Peak Detect” acquisition mode have reportedly been fixed in later firmware versions. However, users have noted that voltage drift appears to be hardware-related rather than firmware-related. Managing expectations is important: not all performance characteristics can be corrected through software.
Contact OWON support directly with:
on their website . If you proceed, ensure the firmware you use matches your hardware revision exactly .
The vibrant community of electronics enthusiasts and engineers on the EEVblog forum provides a wealth of real-world experience with the HDS2102S. One user discovered that firmware files for different models in the HDS200 series (like the HDS242S or HDS272S) are often identical and hashed for verification. For those with a V2.0.4 firmware, there is a possibility of updating to V3.0.1, but only after contacting OWON for guidance.
The v1.51 update ensures that waveforms are accurately mapped to the horizontal grid at high speeds, allowing for precise manual measurements using the on-screen divisions. How to Update Owon typically provides firmware based on the device's serial number range
After a successful , you must do three things to ensure stability. owon hds2102s firmware update
| Version | Notes | |-----------|-----------------------------------------------------------------------| | 1.0.1 | Early production | | 1.1.2 | Improved FFT stability, fixed trigger holdoff issue | | 1.2.0 | Added waveform recording/playback, better LAN stability (if equipped) |
If that doesn’t work: consult the official instructions included with the firmware package.
: Turn on your device, press the System button, and navigate to the System menu to view your current version.
: Firmware updates for the HDS series are often tied to specific serial number ranges (e.g., 2152xxx for HW 3.1). : Installing incompatible firmware can lead to an upside-down screen or a bricked device. Official Advice Safely eject/unmount the USB drive from your operating
You cannot downgrade across major hardware revisions. If you update from v1.2 to v1.3, the bootloader may have been upgraded. Downgrading might semi-brick the NAND driver.
The official OWON PC software requires libusb drivers, but Owowon uses WinUSB drivers instead. If you plan to use this tool, you'll need to install the appropriate drivers using Zadig or the provided driver files in the repository.
Before attempting a firmware flash, you must identify your device's specific hardware revision. Firmware versions for the HDS200 series are ; they are strictly tied to specific serial number ranges and hardware versions.
Before you rush to download files, let’s look at the real-world benefits of a modern firmware build. Using the wrong vendor’s firmware will corrupt the
