StarTech 2-Port PCIe RS232 Serial Card | 16950 UART | PEX2S953
The StarTech PEX2S953 delivers dual RS232 serial connectivity through a single PCIe slot, engineered for demanding computing environments. Built on the ASIX AX99100 chipset with 16950 UART architecture, this adapter achieves 921.6Kbps bidirectional throughput per port while maintaining low CPU overhead via its 256-byte FIFO buffer. Each DB9 port features independently configurable Pin 9 output—selectable between 5V, 12V, or disabled—accommodating diverse peripheral power requirements. The card ships with standard and low-profile mounting brackets, enabling deployment across multiple system configurations. TAA-compliant and validated for Windows and Linux environments, the PEX2S953 integrates seamlessly into x1, x4, x8, or x16 PCIe slots for legacy serial device integration in modern infrastructure.
