FL-9XX (COM5) Driver

The FL-9XX (COM5) driver helps Windows recognize the Hach device over USB and enables compatible software to communicate with it through a serial COM port. It is intended for users connecting the device for the first time or troubleshooting an unrecognized connection in Windows 10, 8.1, 7, Vista, or XP. The COM5 label identifies the assigned port; Windows may assign a different number on another computer.

Key Features

• USB device recognition: Helps Windows identify the connected Hach FL-9XX so compatible applications can access it.
• COM-port communication: Provides the connection needed for software that communicates with the device through a Windows serial port.
• Support for listed Windows systems: Intended for the supported Windows versions above, subject to the compatibility details of the selected driver package.
• Connection troubleshooting: Installing the correct driver can help resolve missing-driver warnings or detection problems caused by an absent or incompatible driver.

How to Install FL-9XX (COM5) Driver

1. Check your Windows version and system type. Confirm whether your installation is 32-bit or 64-bit, then review the package requirements. For Windows 10/11 systems, note that Windows 10 is listed as supported, but Windows 11 compatibility is not confirmed here.
2. Choose a compatible package. Before starting your FL-9XX (COM5) driver download for Windows, verify the device model, supported operating systems, and source. If offered as a free download, confirm that it includes the actual driver rather than an unrelated installer.
3. Prepare the files. Extract the downloaded archive if necessary and read any included instructions. Connect or disconnect the USB device as directed by the package documentation.
4. Install the driver. Run the supplied setup program, or open Device Manager, locate the device, choose Update driver, and browse to the extracted driver folder. Administrator permission may be required.
5. Verify the connection. Restart Windows if prompted, reconnect the device, and check Device Manager for warning icons. Select the assigned COM port in your compatible application; use COM5 only if that is the port Windows shows.

Keep the driver updated by checking for the latest version that explicitly supports your device and operating system. Review compatibility notes before you update, and retain a working driver package in case you need to restore the previous setup.
