Product information

Description

The StarTech 2-Port PCI Express Serial Card (21050-PC-SERIAL-CARD) provides two RS-232 (DB9) serial ports for adding legacy serial communication to a desktop or small form factor (SFF) system. The card supports PCIe 2.0 x1 host interface, includes both standard and low-profile brackets, and is compatible with Windows and Linux operating systems.

Advantages

This dual-port PCIe to RS232 card offers 16C1050 UART support with 256-byte FIFO for transmit and receive, and per-port bidirectional speeds up to 921.6 Kbps. Low-profile brackets are included for SFF installations, and front-panel LEDs indicate serial port status. The card enables continued use of legacy serial peripherals without replacing existing equipment and is supported by a two-year StarTech.com warranty with multi-lingual technical assistance.

Suitable for

Connecting POS terminals and receipt printers
Integrating security systems and access control
Legacy industrial equipment in manufacturing and logistics
Audio/visual installations requiring serial control
IT systems needing COM port retention for specialized software

How to use

Power down the computer and insert the card into an available PCIe x1 slot inside the desktop or SFF chassis. Fit the appropriate bracket (standard or low-profile) to match the system form factor, secure the card with a screw, then power on the system. Install the required drivers for Windows or Linux if the OS does not automatically detect the device. Connect serial peripherals to the DB9 ports and verify communication using serial terminal software or the application that requires COM port access.

Usage recommendations

For stable communication, use quality shielded serial cables and verify COM port settings (baud rate, parity, data bits, stop bits, and flow control) to match the connected device. When installing in SFF systems, ensure adequate clearance and airflow around the PCIe slot to prevent overheating.

Ports & interfaces

Serial interface type:: RS-232
Serial ports quantity: The number of serial ports in a computer or peripheral. A serial port is a serial communication physical interface through which information transfers in or out one bit at a time. The term "serial port" usually identifies hardware more or less compliant to the RS-232 standard, intended to interface with a modem or with a similar communication device. In modern computers and peripherals, serial ports have largely been replaced by USBs and other interfaces.: 2
Expansion card standard:: PCI 2.0
Expansion card form factor:: Full-height / Low-profile
Host interface: Interface that enables a host controller to communicate with a driver.: PCIe
Output interface: The socket (port) where the output connectors are connected.: Serial

Performance

LED indicators:: Activity
Chipset: Set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.: ASIX - AX99100, ASIX - ZT3243LFEY
