Move folders from the CD/download directly to C:\ .
If your device powers up but refuses to stay connected, the internal firmware might be corrupted. You will need a to reflash the AT91SAM7S256 chip with a clean binary. This is an advanced procedure but can revive a bricked unit.
Sometimes a software driver crash mimics a hardware disconnection. Open Windows .
Even if the hardware is fine, wrong drivers can cause "Not Connected" errors.
Physical issues found in clones include: iprog programmer not connected hot
If the iProg only gets hot when a specific adapter is attached, that adapter has a short. Test the main unit without any attachments to see if it remains cool and "Connected." Step 4: Software and Firmware Mismatch
Iprog+ should only be powered via the computer's USB 5V port. There is a known risk of burning out the device if you connect it to an external 12V power supply, which can also produce connection errors.
In other cases, scripts written for one software version may not function properly under another version. A user noted that a Smart 453 script was made for V87, and "if opened it under any lower version getting warning message that might not work correctly".
Disclaimer: Repairing electronic devices involves risks. Ensure the device is unplugged before attempting any physical repairs. Move folders from the CD/download directly to C:\
Right-click the device and select , ensuring you check the box to "Delete the driver software for this device". Restart your computer.
The table below outlines how to distinguish between standard configuration issues and hardware defects: Error Type Likely Cause Primary Symptom Quick Solution Windows Update overwritten files Blinking Red LED / Device Manager Warning Rollback or manually force-install legacy drivers. Power Starvation USB port power limits exceeded Drops connection only during heavy read/write cycles Inject dedicated external power to the adapter. Thermal Fault (Hot) Wrong resistor values on board Device works at first, then drops connection as it warms up Modify board with a 4k7 pull-up and 51k divider . 5. Best Practices to Prevent Connection Dropouts
Choose > Advanced options > Startup Settings > Restart .
Once resolved, follow these best practices: This is an advanced procedure but can revive a bricked unit
To avoid the "programmer not connected" error in the future:
Look for the transistors labeled (NPN) and BC807 (PNP).
Voltage drops cause the iProg's internal components to struggle to maintain a stable state, occasionally leading to communication drops and warm components due to fluctuating power cycles. Step-by-Step Troubleshooting and Solutions
