StarTech.com 1-Port PCI Express RS232 Serial Adapter Card - PCIe RS232 Serial Controller Card - PCIe to DB9 UART16950 - Low Prof

This internal expansion card installs in a PCI Express slot to provide the computer with an RS232 serial port with a DB9 connector. It enables communication with peripheral devices such as printers, card readers, or PIN Pad terminals, achieving transmission speeds of up to 921.4Kbps. Its design includes a pre-installed low-profile bracket and an optional full-height bracket to fit different case form factors.

The adapter uses the Asix AX99100A chipset and is compatible with the standard 16950 UART specification. It features a 128-byte deep FIFO for both the transmitter and receiver, and supports data lengths of 5 to 9 bits. It offers compatibility with PCI Express 1.1 and allows for 5/12V output power on pin 9 via external connection. It works on Windows and Linux operating systems.
