Not Connected New | Iprog Programmer
Do not rely on Windows Update.
Some versions of the iProg software contain self-protection logic.
The phrase is self-explanatory but misleading. It means the iProg software is detecting a hardware unit, but the firmware or driver signature does not match the current software’s expectation.
The keyword here is (New) . The software labels the connected device as "New" because it has either:
If you want a headache-free experience, replace the iPROG clone with a genuine PICkit 3, PICkit 4, or a cheap PicKit2.5 (TL866).
iPROG is old, slow, and unreliable on modern OSes.
But if you must use it:
The "iprog programmer not connected" error is a common hurdle for new users setting up the iProg+ Universal Programmer. This error typically signifies a communication failure between the software, the device driver, and the physical hardware. 🛠️ Core Troubleshooting Steps
If you encounter the "Programmer not connected" message, follow these primary diagnostic steps:

The "Not Connected" error in the iProg software interface typically stems from a breakdown in the USB-to-Serial communication layer. Unlike native USB devices, the iProg hardware architecture often relies on a bridge controller (commonly CH340 or FT232) to communicate with the host PC. A failure in this chain—whether driver-based, power-based, or firmware-related—results in the software inability to enumerate the hardware. This paper dissects the root causes and proposes systematic solutions.
The "iProg programmer not connected" error is rarely a fatal device failure. In 90% of cases involving new units, the culprit is a missing CH340 driver, an incorrect COM port number assignment, or a low-quality USB cable. Addressing the USB-to-Serial bridge configuration typically resolves the issue immediately.
The "Programmer is not connected" error with iProg+ devices typically stems from driver installation failures, power supply issues, or hardware component defects common in clone units. Core Troubleshooting Steps
Driver Verification: This is the most common cause. If the red LED on the device is blinking, it indicates the hardware is receiving power but cannot communicate with the PC.
Action: Manually uninstall the current driver from the Windows Device Manager and reinstall the specific driver version provided with your software. Check the Reveltronics Forum for official driver installation guides. LED Status Indicators: No LED: Programmer is damaged or has no power supply. Blinking Red: Driver is missing or incorrectly installed.
Solid Green/Blue: Programmer is working and correctly connected. Hardware Fixes for Clone Units
Many new iProg+ clone units have "Port Errors" due to incorrect internal components. Common hardware modifications include:
Resistor Replacement: Some units require changing pull-up resistors on the mainboard or adjusting the ADC voltage divider to resolve 10V/12V power errors. MC3406 Resistors: Replacing current sense resistors with variants is often necessary for stable operation.
External Power: Ensure external power is connected when using specific adapters like RFID or UART, as some functions cannot run on USB power alone. Software & System Configuration
OS Compatibility: While newer software versions attempt to support Windows 11, users frequently report "not connected" errors on this OS. Running the software in Compatibility Mode for Windows 7 or 10 is often recommended.
USB Port Power: High-power devices like the iProg+ may struggle with USB 3.0 ports on some laptops (e.g., Surface Pro). Try using a USB 2.0 port or a powered USB hub if the connection is intermittent.

When your new iProg+ programmer displays a "Programmer not connected" error, it typically stems from driver installation issues, hardware power failures, or software configuration mismatches. Immediate Troubleshooting Steps
If you are seeing this error on a new device, check these basics first: LED Status Check:
No Lights: Indicates the programmer has no power supply or is physically damaged.
Blinking Red LED: Usually means the hardware is functional, but the driver is not installed or recognized correctly.
Solid Green/Blue: Typically indicates a successful connection.
USB Connection: Connect the device directly to your PC's motherboard ports (on the back for desktops) rather than a USB hub, as hubs often provide insufficient power.
Cable Swap: Faulty USB cables are a common cause of "Not Connected" errors; try a known working cable. Step-by-Step Driver Installation
Most connection errors are resolved by manually installing the specific iProg+ drivers, especially on Windows 10 and 11. Fix Unrecognized USB Device? 12 Solutions (2025) - HP
When your iProg+ programmer displays the "Not Connected" status despite being a new device, it usually stems from a driver conflict, a power supply issue, or a serial number mismatch in the software. Troubleshooting Steps
Check Driver Installation: The most common cause is the lack of proper FTDI drivers. Open Device Manager on your PC.
Look for "Ports (COM & LPT)" or "Universal Serial Bus controllers."
If you see a yellow exclamation mark or "Unknown Device," right-click and manually update the driver using the "Drivers" folder provided with your iProg software.
Verify Serial Number (SN): The software and the hardware must share the same serial number to communicate. The phrase is self-explanatory but misleading
Check the sn.txt file in your software directory. It must match the hardware ID (common IDs for clones include 1, 35, or 45).
If they don't match, the software will refuse to initialize the connection. USB Port & Cable:
Ensure you are using a USB 2.0 port. Some iProg clones struggle with USB 3.0 (blue ports).
Try a different USB cable; the ones bundled with the units are often of lower quality and may fail to provide stable data transmission.
Power Supply: iProg requires stable 12V for many operations (like EEPROM or MCU programming). Ensure your external power supply is connected if the script you are running requires more than just USB power.
Disable Antivirus: Security software often flags iProg executable files or scripts as "cracks" or malware, deleting essential .dll files needed for the connection. Re-extract the software with your antivirus temporarily disabled. Common Status Indicators Red LED: Power is reaching the board.
Green LED: Data communication is active. If only the red light stays on and the software says "Not Connected," the PC is not "talking" to the internal FTDI chip.
