Extend the life of critical serial equipment without replacing proven devices. The StarTech PEX8S1050 adds eight DB9 RS232 ports through a single PCI Express x1 slot, giving you a practical path for connecting PLCs, control systems, scanners, medical devices, and other legacy endpoints that still depend on serial communication. Built around a 16C1050 UART, this adapter supports bi-directional RS232 communication at up to 921.6 Kbps per port and includes a 256-byte FIFO to help maintain stable data handling across multiple attached devices. The included 18-inch DB62-to-8x DB9 breakout cable simplifies installation, while the low-profile design fits space-constrained systems. Power output options on DB9 pin 9 support 12 V, 5 V, or no power, with up to 3 A total. For environments where uptime and compatibility matter more than replacing hardware on schedule, this card provides a controlled, cost-effective bridge between modern PCIe systems and serial infrastructure already in production. TAA compliance also makes it suitable for government and regulated procurement workflows.
