Low Profile PCI Express RS232 Serial Adapter Card - 1 Port PCIe to DB9 - 16950 UART - Windows & Linux (PEX1S953LP)

This PCI Express RS232 Serial Adapter Card allows you to add a single DB9 serial port to a computer via a PCIe slot. It is designed for systems that require communication with legacy or industrial serial devices such as card readers, printers, modems, and control systems. The card uses the ASIX AX99100 chipset and supports speeds up to 921.6Kbps, making it suitable for high-speed data transfer needs in environments like factories or laboratories. It is ideal for users who need to connect older equipment to modern computers without the need for additional external adapters.

The card features a 16950 UART with a 256-byte FIFO buffer and supports a 9th data bit for enhanced communication capabilities. It also provides optional power output of 12V, 5V, or none through pin 9, allowing flexibility in powering external devices. This makes it useful in applications where external power requirements vary. The card is compatible with both Windows and Linux operating systems, ensuring broad integration into mixed environments. Its support for various data bit configurations (9, 8, 7, 6, 5) adds to its versatility in different communication scenarios.

The card comes with a low-profile bracket pre-installed, making it suitable for compact cases, while an additional full-profile bracket is included for compatibility with standard desktop cases. This dual bracket option ensures ease of installation regardless of the system's form factor. The card is PCIe 1.1 compliant and includes a lifetime warranty and free technical support from StarTech.com. Users can rely on its durability and performance in demanding environments such as industrial automation or scientific research.

It is commonly used in point-of-sale terminals, PLCs, medical equipment, and other industrial applications where reliable serial communication is essential. The card's ability to handle high baud rates and provide stable power output makes it a reliable choice for these use cases. However, it is important to note that this card is not suitable for systems without available PCIe slots or those requiring multiple serial ports.
