AIS Class B Transceiver (COM4) Driver

The AIS Class B Transceiver (COM4) driver allows Windows to recognize the USB connection to your Srt Marine transceiver and make its serial interface available to compatible marine software. It is intended for users setting up the device on a PC or troubleshooting an unrecognized USB connection or missing COM port.

Key Features

• USB-to-serial access: Provides the connection interface that compatible navigation and AIS applications use to communicate with the transceiver.
• COM port identification: Helps Windows expose the device as a serial port. Although the device name includes COM4, the assigned port number may differ between computers or USB connections.
• Legacy Windows support: Listed operating systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package that matches your Windows version and, where applicable, its 32-bit or 64-bit architecture.
• Connection troubleshooting: Installing the appropriate driver can address recognition problems caused by a missing or incompatible driver; it does not replace the transceiver’s firmware or marine application settings.

How to Install AIS Class B Transceiver (COM4) Driver

1. Check your system. Confirm your Windows version and system type before selecting an AIS Class B Transceiver (COM4) driver download for Windows. For Windows 10/11 users, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
2. Verify the package. Look for the latest version explicitly compatible with your Srt Marine device and operating system. If choosing a free download, check its source and any included installation instructions before opening it.
3. Install the driver. Follow the package’s setup instructions, including guidance on when to connect the USB cable. If no installer is provided, use Device Manager’s Update driver option and browse to the extracted driver folder.
4. Connect and check. Power the transceiver as directed by its documentation, connect it to the PC, and inspect Device Manager. Confirm that it appears without a warning icon and note the assigned COM port.
5. Configure your application. Select that COM port in your AIS or navigation software and apply the communication settings specified in the transceiver documentation. Restart Windows if the installer requests it.

Keep the driver updated when a compatible release addresses a connection issue or supports a system change. Before you update a working installation, review compatibility notes and retain the previous installer in case you need to roll back. A newer driver is useful only when it suits your hardware and Windows setup.
