TThe SIIG DP 1‑Port RS‑232 Serial PCI with 16550 UART (model JJ‑P01311‑S1) is a compact and efficient internal adapter card designed to add a standard 9‑pin serial (DB‑9) RS‑232 port to a PCI‑equipped desktop computer. Utilizing a high‑speed 16550 UART chip with a 256‑byte FIFO buffer, it supports data transfer rates of up to 230 Kb/s — ideal for legacy peripherals like modems, point‑of‑sale systems, industrial machinery, and serial printers. Its universal PCI design works across both 3.3 V and 5 V slots and is fully compliant with PCI Local Bus Specification rev.2.3. The dual‑profile form factor includes both standard and low‑profile brackets, ensuring compatibility with full‑tower and slimline chassis. Certified to CE, FCC, and RoHS standards, this card delivers reliable serial connectivity, supports a broad range of Windows (including XP, Vista, 7, 8, 10) and DOS environments, and comes backed by a two‑year warranty. The package includes the card, spare low‑profile bracket, driver CD, and user manual, making it an affordable and practical solution for systems requiring RS‑232 support.
