Once the DFU tool says "Update Successful" (approx. 90 seconds), close the tool and unplug the USB cable.

  • Signal Verification: Use the built-in 1kHz square wave on the probe compensation terminal. Go to 500mV/div and 500us/div. The rising edge should be clean. If there is overshoot or a flat line, the FPGA logic was not updated correctly (rare, but rebooting usually fixes it).

    • If you're still unsure about any steps or if your device doesn't seem to be updating correctly, consider contacting OWON's technical support for assistance.

    Updating the firmware on an Owon HDS2102S requires extreme caution because hardware versions (HW) and serial numbers dictate compatibility. Attempting to install the wrong version can permanently brick your device. Critical Pre-Check

    Before attempting any update, you must identify your current version and hardware: owon hds2102s firmware update verified

    Check Current Version: Navigate to the System or About menu on your device to find your current firmware (e.g., V1.x.x, V2.x.x, V4.x.x). Verify Compatibility:

    Firmware versions are not interchangeable across mainboard versions. For example, a V1.x.x unit cannot be upgraded to V2.x.x.
