This is a low-profile PCI Express expansion card designed to add four RS-232 serial ports to a computer. It is ideal for users who need to connect legacy serial devices to modern systems that lack native serial ports. The card uses a native single-chip, single-lane PCI Express design, which ensures efficient performance and compatibility with standard PCIe slots. It is suitable for both standard and small form factor computers, making it a versatile solution for various computing environments.

The card supports data transfer rates up to 128000bps, ensuring reliable communication with serial devices. Each port features a 256-byte deep FIFO buffer, which helps reduce CPU overhead and improves data handling efficiency. The built-in 16C450/550 compatible UART ensures compatibility with a wide range of serial devices and applications. This makes it a good choice for industrial automation, embedded systems, or any scenario where serial communication is required.

The card comes with both standard and low-profile mounting brackets, allowing for easy installation in different types of computer cases. It is compliant with the PCI Express Base Specification 1.1, ensuring compatibility with a wide range of motherboards and systems. The green color of the card helps in identifying it easily during installation. Users should ensure their system has an available PCIe slot and proper power supply before installation.

The card is part of StarTech.com's lineup of expansion solutions, known for their reliability and compatibility. It is designed for users who need to maintain connectivity with older devices without the need for additional external adapters or converters. However, it may not be suitable for systems that do not have a PCIe slot or require higher data transfer rates beyond what the card supports.
