PCI Express RS232 Serial Adapter Card StarTech.com 1‑Port 16950 UART

Description

Product Overview

The StarTech.com PCI Express RS232 Serial Adapter Card is engineered to provide a robust, single‑port serial solution for a wide range of computing environments. Built around the ASIX AX99100 chipset, the card features a 16950 UART that can handle bi‑directional RS232 communication at speeds up to 921.6 Kbps, ensuring fast and reliable data transfer for demanding applications. Its low‑profile bracket fits into compact desktop and server chassis, while an optional full‑height bracket is included for greater installation flexibility. The adapter supports both Windows and Linux operating systems, offering plug‑and‑play compatibility with most modern drivers. Power can be supplied through the PCIe slot or configured via pin 9 to deliver either 12 V, 5 V, or no external voltage, allowing you to match the power requirements of your specific hardware setup. With a 256‑byte FIFO buffer and a selectable 9th data bit, the card provides ample headroom for high‑throughput serial communication, making it suitable for point‑of‑sale terminals, industrial automation, scientific instrumentation, and more.

Usage

Designed for versatility, this serial adapter excels in environments where reliable, high‑speed serial connectivity is essential. In retail settings, it can link POS terminals to barcode scanners, receipt printers, and cash drawers, delivering smooth transaction processing without bottlenecks. In manufacturing and factory automation, the card interfaces with programmable logic controllers (PLCs), motor controllers, and sensor arrays, enabling precise control and monitoring of equipment. Laboratory and research facilities benefit from its ability to connect oscilloscopes, data loggers, and other scientific instruments that rely on RS232 communication for accurate data capture. The low‑profile design also makes it an excellent choice for space‑constrained servers that need to maintain legacy serial connections while supporting modern operating systems. Whether deployed in a rugged industrial enclosure or a quiet office workstation, the adapter’s configurable power options and broad OS support simplify integration and reduce the need for additional adapters or converters.

FAQ

What operating systems are supported by this serial adapter?

The adapter is fully compatible with modern Windows versions (including Windows 10 and Windows Server editions) and a wide range of Linux distributions. Drivers are provided by StarTech.com and are regularly updated to maintain compatibility with the latest kernel releases. This ensures that the card can be deployed in mixed‑OS environments without the need for additional software layers.

Can I use the card in a low‑profile server chassis?

Yes. The card ships with a low‑profile bracket pre‑installed, making it ideal for slim server cases and desktop PCs where space is limited. If a full‑height slot is available, the included full‑height bracket can be swapped in, providing flexibility for future upgrades or different mounting requirements.

How does the configurable power feature work?

Power can be supplied via the PCIe slot or manually configured through pin 9 on the card. By selecting either 12 V, 5 V, or leaving the pin unconnected, you can match the power needs of attached devices such as external RS232 converters or custom hardware. This feature is especially useful in industrial settings where power budgets may vary.

Is the card suitable for industrial automation applications?

Absolutely. The robust 16950 UART, high data‑rate capability, and reliable FIFO buffering make the adapter well‑suited for connecting PLCs, motor controllers, and sensor networks. Its rugged design and support for both Windows and Linux platforms allow it to be integrated into a variety of automation systems, from small‑scale test rigs to large‑scale production lines.

What warranty and support options are available?

StarTech.com provides a standard limited warranty that covers manufacturing defects for a period of one year from the date of purchase. In addition, the company offers technical support via phone, email, and an online knowledge base. Customers can also access firmware updates and driver downloads through the StarTech.com support portal, ensuring the product remains up‑to‑date throughout its service life.
