7. Troubleshooting
- Driver Installation Issues: If the cable is not recognized or drivers fail to install, ensure you are using the correct drivers for your Windows operating system (XP, 7, 8, 10). Try running the driver installer in compatibility mode if issues persist on newer Windows versions.
- Radio Cycling Self-Test: If your radio continuously cycles through a self-test when connected, this may indicate a compatibility issue with your specific radio model or the programming software version. Verify that your radio model is listed as compatible and that you are using the correct and updated CPS software.
- Connection Problems: Ensure the RJ-45 connector is fully and securely inserted into the radio's programming port. A loose connection can prevent proper communication.
- Software Not Detecting Cable: Confirm that the correct COM port is selected within your radio programming software. Check your computer's Device Manager to identify the assigned COM port for the USB Serial Port.
