The AirLink101 USB to Serial Port driver helps Windows recognize the adapter and communicate with equipment that uses a serial connection. If you use it with a serial printer or another compatible peripheral, the correct driver allows software to access that equipment through an assigned COM port.

Key Features

• USB-to-serial communication: Enables applications to send and receive data through the AirLink101 adapter when a compatible driver is installed.
• COM port access: Makes the serial connection available to programs that require a COM port, including software used with supported serial printers.
• Configurable connection settings: Lets you adjust supported serial parameters, such as baud rate and flow control, through Windows or your application to match the connected equipment.
• Device recognition and troubleshooting: Helps Windows identify the adapter, so you can check its status and assigned port in Device Manager.

How to Install

1. Confirm the adapter and Windows version. Check the device label or its hardware IDs in Device Manager before selecting a download. For Windows 11, 10, 8, or 7, verify that the driver package explicitly supports your operating system and architecture; older adapter revisions may have different compatibility requirements.

1. Download and extract the matching driver. Save the AirLink101 driver package locally. If it is compressed, extract its contents before installation. Review any included instructions for adapter-specific requirements.

1. Install the driver. Run the supplied installer, if available, and follow its prompts. If the package contains driver files without an installer, open Device Manager, locate the adapter, select “Update driver,” and browse to the extracted folder.

1. Connect the adapter and verify detection. Follow the package instructions on when to plug it in. Once installation finishes, look under “Ports (COM & LPT)” in Device Manager and note the assigned COM number. Restart Windows if requested.

1. Configure and test your peripheral. Select the same COM port in your printer software or other application, then match the serial settings to the equipment’s requirements. Try a test print or communication check.

The adapter driver handles the USB-to-serial connection; a connected printer may still need its own driver or compatible printing software. If communication fails, check the cable, COM port selection, and serial settings before reinstalling.

Common Issues and Fixes

• Driver install fails or is blocked: Disconnect the AirLink101 USB-to-serial adapter, run the installer as administrator, and reboot before reconnecting. If Windows blocks an older package, check for a signed/updated driver rather than forcing installation.
• Device not detected / no COM port appears: Try a different USB port and cable, then open Device Manager and look for Unknown Device or Ports (COM & LPT). Uninstall any failed entry, reconnect the adapter, and rescan for hardware.
• Driver or COM-port conflicts: Remove older USB-serial/Prolific-style drivers and unused COM ports in Device Manager, reboot, then install only the matching AirLink101 driver. If the COM number is wrong or in use, reassign it under Port Settings > Advanced.
