Item Description:
Adds four RS-232 serial ports to PCI Express enabled computer systems

Adds four RS-232 serial ports to PCI Express enabled computer systems

Product Features:

  • PCI Express 1-lane (x1) adapter works with PCI Express slots with different lane width
  • Installs in any available PCI Express slot
  • Four high-speed 16550 UART RS-232 serial ports (9-pin) support asynchronous baud rates up to 921Kbps
  • Works as standard RS-232 port or with 5V or 12V power output for devices that require power (such as handheld scanners; table scanners; POS displays; etc.). Configurable via jumpers with silk-screened settings on PCB
  • Built-in 256-byte FIFO buffers dramatically increase data transmit/receive speed; especially under Windows multitasking environment
  • Spare enhanced low profile bracket is included to work in low profile chassis
  • Onboard power connector to provide reliable power source for devices that require power
  • 4-layer PCB board: separate layers for data and grounding. Greatly reduces signal noise and loss. Delivers more reliable high-speed data transfers
