ME-9000/PCI Port 3 - RS232 (COM5) Driver

The ME-9000/PCI Port 3 – RS232 (COM5) driver enables Windows to recognize and communicate with the corresponding serial port on your Meilhaus Electronic hardware. It is intended for users setting up RS232 equipment, restoring an unrecognized port, or troubleshooting communication through COM5.

Although listed in the USB category, the device name identifies a PCI serial interface, so confirm the hardware identity before choosing a package. The listed operating systems are Windows 10, 8.1, 7, Vista, and XP; select a driver that matches both your Windows release and system architecture.

Key Features

• Serial-port recognition: Allows Windows to identify the associated RS232 port and make it available to compatible software.
• Communication support: Provides the driver interface needed for applications to exchange data with connected serial equipment.
• Device Manager integration: Helps you check the port’s status, inspect driver information, and investigate installation errors.
• Windows-specific packages: Choosing the appropriate release helps avoid compatibility problems across the listed Windows versions.

How to Install ME-9000/PCI Port 3 – RS232 (COM5) Driver

1. Identify your system and device. Check your Windows version and whether it is 32-bit or 64-bit. In Device Manager, compare the device’s hardware IDs with those supported by the driver package.
2. Choose a verified package. Before starting your ME-9000/PCI Port 3 – RS232 (COM5) driver download for Windows, confirm that the package comes from Meilhaus Electronic or a trusted source. A free download should still include clear compatibility information.
3. Prepare the files. Extract the downloaded archive if necessary, read any included instructions, and close applications using the serial port.
4. Install the driver. Run the supplied installer, or open Device Manager, right-click the relevant device, select Update driver, and browse to the extracted driver folder. Restart Windows if prompted.
5. Test the connection. Confirm that Device Manager shows no warning icon. Check the assigned COM number rather than assuming it remains COM5, then configure your application’s baud rate, parity, and other serial settings to match the connected equipment.

Keep the driver updated when a compatible release addresses your issue or improves support. Check the latest version against your hardware before you update, and retain a working installer in case you need to roll back. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility requires separate confirmation from the vendor.
