STARTECH 16-Port RS232 DB9 Low/Full-Profile Computer Accessory

16 RS232 DB9 ports for low or full-profile systems

This accessory adds sixteen RS232 serial ports with DB9 connectors to a computer. It fits both low-profile and full-profile chassis without modification. The card is suited for industrial automation, legacy equipment control or any environment that still relies on serial communication.

Sustained multi-port serial throughput

Each of the sixteen ports operates independently under continuous load so multiple devices can transmit simultaneously without contention. The design maintains stable signal levels over long cable runs typical in factory or laboratory settings. No active cooling is required and the board draws power solely from the expansion slot.
