Detailed Specifications

StarTech PEX16S550LP 16 Port RS232 PCIe Serial Card

overview

The StarTech PEX16S550LP is a high-density PCIe serial interface card that adds 16 RS-232 ports to a system through a single PCI Express slot. It is designed for environments that require multiple serial connections such as industrial automation, POS systems, telecom, and legacy device integration.

Built on 16C550 UART architecture, the card supports stable asynchronous serial communication with configurable baud rates and broad OS compatibility. It uses breakout cables from multiple DB-44 connectors to DB-9 ports, enabling high port density while maintaining standard RS-232 connectivity.

Deployment fits servers or workstations requiring consolidation of serial interfaces into a single PCIe slot. Not suitable for RS-422/485 requirements or environments needing isolated serial channels without external converters.

key features

  • adds sixteen RS-232 serial ports via PCIe slot
  • 16C550 UART ensures stable serial communication
  • high-density DB44 to DB9 breakout connectivity
