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 Lifetime warranty and free lifetime technical support.

The Advantage

  • Selectable 5/12V power output on one of four different pins provides the flexibility needed to connect nearly any powered serial device
  • The included breakout cable saves expense as an all-in-one solution, and allows the addition of multiple RS232 serial ports through a single PCI slot
  • Includes both low profile/half-height and full profile brackets to ensure fitment into a broad range of system form factors
