2-Port PCI RS232 Serial Adapter Card - StarTech.com PCI2S5502 - Dual DB9 Ports - Standard & Low Profile Brackets - Windows/Linux

This is a 2-port PCI RS232 serial adapter card designed to add two RS232 (DB9) serial ports to a computer via a PCI slot. It is ideal for users who need to connect legacy serial devices such as card readers, printers, PIN pads, and modems. The card is based on the ASIX MCS9865 chip with a 16C550 UART, offering speeds up to 115.2Kbps per port and supporting various data configurations including 5 to 9 data bits and multiple parity options. It is compatible with both Windows and Linux operating systems, making it suitable for use in mixed environments.

The card includes a standard profile bracket that is pre-installed, along with two optional low-profile brackets for easier installation in smaller cases. It supports auto IRQ and IO assignment, as well as IRQ sharing, which helps in managing system resources efficiently. The card is a direct upgrade from previous models like the PCI2S550_LP and PCI2S550, offering improved performance and reliability. It is backed by a lifetime warranty and free 24/5 technical support from StarTech.com.

The card features a 256-byte FIFO buffer, which helps in reducing data loss during high-speed transfers. It supports flow control options such as Xon/Xoff, RTS/CTS, and none, allowing users to manage data transmission effectively. The card operates within a wide temperature range of 0°C to 70°C and can be stored in temperatures ranging from -20°C to 85°C. It is designed for use in industrial environments where reliability and durability are essential.

Installation is straightforward with the included brackets and quick-start guide. The card is suitable for use in point of sale terminals, PLCs, CNC machines, scientific sensors, medical equipment, scanners, and oscilloscopes. It supports both standard and low-profile brackets, making it adaptable to different case form factors. The card's black color and compact design make it easy to integrate into existing systems without taking up too much space.
