    4-Port RS232 PCI Serial Card Adapter with Power Output


    Add 4 RS232 serial ports with 5V or 12V selectable power output to your computer, through a PCI slot

    The PCI4S954PW 4-Port PCI Serial Card (with Power Output) turns a PCI slot into 4 RS232 (DB9) serial connections and enables compatible devices to draw power from the serial ports.

    Suitable for many RS232-powered serial applications, this PCI serial card offers a selectable 5V or 12V power option, capable of power output using pin 1, 4, 8 or 9, which enables you to configure the card to suit the requirements of your powered RS232 devices.

    A flexible solution for adding serial ports to full-sized, or small form factor systems, the 4-port serial card includes both low and full profile brackets while the included breakout cable helps to avoid cluttered connections.

    Backed by a StarTech.com Lifetime warranty and free lifetime technical support.
