DIACOM USB Interface Cable (COM4) Driver

The DIACOM USB Interface Cable (COM4) driver enables Windows to recognize Rinda’s USB diagnostic interface cable and communicate with compatible DIACOM software. It is intended for technicians and boat owners who need to connect a PC to supported marine diagnostic equipment, especially when the cable appears as an unknown device or its serial connection is unavailable.

Before choosing a DIACOM USB Interface Cable (COM4) driver download for Windows, check that the package matches your operating system and system architecture. Supported operating systems listed for this device are Windows 10, 8.1, 7, Vista, and XP. If you are checking Windows 10/11 compatibility, note that Windows 11 is not included in this support list; confirm compatibility with Rinda before attempting installation. Choose a free download only from a trusted source, and verify that it is intended for this interface.

Key Features

• USB interface recognition: Helps Windows identify the Rinda cable so compatible diagnostic software can access it.
• Serial port communication: Provides the connection associated with the cable’s COM port. Although the device name includes COM4, Windows may assign a different port number.
• Diagnostic software connectivity: Supports communication between the connected interface and compatible DIACOM applications; the driver does not replace the diagnostic software.
• Support for listed Windows systems: Enables use on supported Windows versions when the correct driver package is selected.

How to Install DIACOM USB Interface Cable (COM4) Driver

1. Check your Windows version and whether your system is 32-bit or 64-bit. Select a matching package and review any included compatibility notes.
2. Download the driver from a trusted source. Extract the files if they are supplied in a compressed archive.
3. Close diagnostic applications, then run the installer if one is provided. Follow its instructions about when to connect the USB cable.
4. If manual installation is required, open Device Manager, locate the interface, select Update driver, and browse to the extracted driver folder.
5. Restart Windows if prompted. Check Device Manager for warning icons and the assigned COM port, then select that port in your DIACOM software if required.

Keep the driver updated when Rinda provides a compatible release that addresses your needs. Before you install the latest version, review its supported operating systems and release notes. An update may resolve connection issues, but software settings, USB connections, and the selected COM port are also worth checking.
