(blue ports). Try connecting to a standard USB 2.0 port or using a USB hub. Check the USB Cable

When diagnosing a newly unboxed iProg unit that refuses to connect, systematically work through this quick triage list: Ensure the device is connected to a dedicated .

Add the entire iProg folder to your antivirus before turning protection back on. 3. Best Practices for Running iProg Software

The clear blue USB cables included in many clone kits are notoriously low quality. Replace it with a high-shielded, shorter USB cable (like a high-quality printer cable) to eliminate data packet drops. 4. Run the Software in Compatibility Mode

If your software setup is flawless but a brand-new clone still shows "Programmer is not connected" or returns a , the underlying circuit board may have bad resistor or capacitor tolerances.

Upon reboot, press or F7 to select "Disable driver signature enforcement."

Add the entire extracted folder to your antivirus exclusion list. This ensures Windows does not delete critical .dll files or the main iprog.exe script.

With the device powered and connected, measure the voltage on the GND and VCC pins of the main IC. It should be 3.3V or 5V depending on the design. Low or fluctuating voltages indicate power supply failure. The upper power board can be removed and tested separately.

Does the device appear under in Device Manager without errors?

Some antivirus programs flag the iProg scripts as "false positives," which can prevent the software from initializing the connection to the hardware. REVELTRONICS Programmer is not connected (V1.9.0) - REVELTRONICS

| | Likely Cause | Recommended Solution | |-------------|-----------------|--------------------------| | Device shows as "unknown" in Device Manager | Driver installation failed | Uninstall and reinstall drivers; try different USB port | | Programmer detected but won't connect to target | Wiring or power issue | Check RESET pin; try "Connect under reset"; verify power supply | | Error only with certain scripts | Script compatibility issue | Check script file extensions; use compatible script versions | | Works on Windows 7 but not 10 | OS compatibility | Use compatibility mode; disable security features; try virtual machine with Windows 7 | | Clone device not working | Software version mismatch | Use device-specific software version (V777, etc.) | | Intermittent connection | Power or cable issue | Use powered USB hub; replace USB cable | | "Power overload" error | Power supply problem | Use original USB cable; avoid external power |

Using incompatible software versions is a common issue, especially with clone devices. For instance, if you have an iPROG V777 clone, you need specifically the "777 serial software" rather than generic iPROG software versions like 85-78-55.
