PCI Express Serial Card SIIG Four Port 921Kbps

Description

Product Overview

The SIIG PCI Express Serial Card (model JJ-E40011-S5) delivers four high‑speed RS232 DB9 ports through a single x1 PCI Express slot. Designed for Windows systems, the card measures 4.72 x 3.66 x 0.87 inches and weighs just 1.6 ounces, making it a compact addition to any desktop. Each port features a 16550 UART with a 256‑byte FIFO buffer, supporting asynchronous baud rates up to 921 Kbps. Integrated jumper‑set power options provide 5 V or 12 V to attached devices, eliminating the need for external power supplies.

Usage

This card is perfect for point‑of‑sale terminals, barcode scanners, handheld data collectors, and industrial control equipment that rely on RS232 communication.
