| Issue | Possible Cause | Solution | | :--- | :--- | :--- | | | The radio's firmware is too old or new for the CPS version you are using. | Obtain a different version of the CPS, either older or newer, to match the radio's firmware. | | "Not Compatible" Error When Reading | The CPS version does not support the radio's specific firmware revision. | Find a version of the CPS that explicitly states compatibility with your radio's firmware. Try the R03.06.00 or R03.11.15 builds mentioned earlier. | | Can't Read or Write | Wrong COM port selected, faulty cable, or loose connection. | Verify the COM port settings in the CPS. Try a different USB port. Check all physical connections. Test with another cable if possible. | | USB Cable Not Recognized | Missing or incorrect USB driver (especially with counterfeit FTDI chips). | Install the official FTDI Virtual COM Port (VCP) driver. Avoid using cheap, counterfeit cables with fake chips. | | Radio Powers Off During Programming | Insufficient power supply or unstable connection. | Ensure the radio is connected to a stable 12V power source, not just battery power if possible. | While these families look similar, using the wrong
