Keep serial infrastructure connected with a PCIe expansion card designed for dependable RS232 access in modern systems. The StarTech PEX2S953LP adds two DB9 serial ports through a PCI Express 1.1 interface, giving you a clean way to support legacy equipment without external dongles or additional host overhead. This card is built for environments where serial connectivity still matters: industrial controllers, point-of-sale devices, lab instruments, and administrative consoles. With data transfer rates up to 921.4 Kbps and 256-byte FIFO depth per transmitter and receiver, it is suited to applications that need stable, predictable communication rather than consumer-grade convenience. Installation is straightforward in compatible low-profile or full-profile systems, making it a practical fit for rack servers and compact workstations alike. TAA compliance also makes it appropriate for procurement environments with sourcing requirements. For teams maintaining mixed-generation infrastructure, this card preserves access to essential serial devices while keeping the system architecture tidy and serviceable.
