Interface card Internal PCIe Lanberg PCE-DB9-004

The Lanberg PCE-DB9-004 is an internal PCIe interface card that adds serial connectivity to desktop systems. Designed for installation into a PCI Express slot, the card provides DB9 serial ports for connecting legacy equipment, industrial devices, modems, or serial consoles. It is compatible with a range of Windows operating systems and has compact dimensions that fit standard PC cases.

Advantages

The card delivers a straightforward way to expand a PC's connectivity with a reliable DB9 serial interface. Its PCIe output ensures stable data transmission while keeping installation simple. Compact physical dimensions allow fitting into most desktop towers without occupying significant space or interfering with adjacent components. Broad compatibility with common Windows versions simplifies deployment in existing systems.

Suitable for

• Connecting industrial controllers and sensors that use RS-232 serial communication
• Adding serial ports for network equipment configuration via console ports
• Using legacy peripherals such as barcode scanners, receipt printers, or modems
• Home or office PCs requiring additional legacy serial interfaces

Key specifications

How to use

Power down the computer and open the case following manufacturer safety guidelines. Insert the card into an available PCI Express slot and secure it to the chassis. Close the case and power on the system. Install the appropriate drivers for your Windows version if the operating system does not automatically detect the device. After driver installation, connect serial devices to the DB9 ports and configure serial port parameters (baud rate, parity, stop bits, flow control) in the operating system or application to match the connected equipment.

Recommendations

Use short, shielded serial cables where possible to minimize signal degradation and electromagnetic interference. Verify driver compatibility with your specific Windows build before deployment and ensure BIOS/UEFI settings allow the PCIe slot to be active. For industrial environments, place the PC and cable routing away from heavy electrical noise sources and secure connectors to prevent accidental disconnection.
