Description
The Galileo PETR02A is a high-performance serial expansion card designed to integrate legacy RS-232 devices into modern computing environments. Utilizing a PCI-Express 1X interface compatible with 2.0, 3.0, and 1.0 specifications, this card offers two independent 9-pin serial ports. It features the industry-standard 16c550 UART with a 256-byte FIFO buffer, ensuring low-latency communication and reliable data integrity for critical industrial and commercial applications.
This product is for:
- Industrial automation engineers requiring stable connections for PLC and CNC machinery.
- IT professionals maintaining legacy server hardware or networking equipment via console ports.
- Retail business owners integrating POS systems, barcode scanners, and receipt printers.

Installing the PETR02A is a straightforward process thanks to its broad compatibility with various PCI-E slot sizes. In practical use, the card maintains consistent 115.2Kbps throughput without data loss, even during full-duplex operations. The hardware flow control effectively manages data traffic, preventing buffer overflows when communicating with older hardware. Its native support for a wide range of operating systems, from legacy Windows XP to modern Windows 10 and Linux, makes it a versatile tool for cross-platform environments.
Unlike USB-to-Serial adapters which often suffer from driver instability and latency issues, the Galileo PETR02A provides a direct bus-level connection. This results in significantly lower CPU overhead and more precise timing, which is essential for industrial synchronization. Compared to older PCI-based serial cards, the PETR02A utilizes the faster 2.5Gbps bandwidth of the PCI-Express architecture, ensuring that the serial ports are never bottlenecked by the system bus.
