1-Port PCI Serial Cards

Easily add additional serial ports to your system. The low profile PCI Multi-1/LPCI is equipped with SystemBase’s powerful semiconductors to deliver maximum performance up to 921.6Kbps with the world’s leading 256 byte FIFO preventing overrun errors. Combine that with the need for fewer components and you get cost-effective and reliable connections to your serial devices.

Price: from $29.00

Multi-1/LPCI Multiport Serial Card Features:

  • Speed: Max 921.6Kbps
  • PCI, PCI-X BUS support
  • RS232 or RS422-RS485 with DB9 Connector
  • World’s Largest 256byte FIFO Integrated
  • 15KV Surge Protection
  • Power to the pins (RI signal) delivers +5/12 volts
  • Slew-rate limit control

The Multi-1/LPCI card is a low-profile card that comes with an interchangeable full-height bezel. The design includes high-performance 15,000 volt Surge Suppression to protect against electrical spikes which cause blown ports. Designed into the card is the capability to supply 5V or 12V power to an external device by using pin 9 (RI signal line). This functionality is ideal for connecting low power devices such as barcode readers and receipt printers eliminating the need for an external power supply.
