Product Details


The PCI2S4851050 2-Port PCI Serial Adapter Card (RS422/RS485) with 161050 UART adds two DB9 RS422/RS485 serial ports, using a single PCI expansion slot.

The PCI serial card offers a high performance 16C1050 UART and supports both 2-wire and 4-wire RS485 modes. The card delivers an efficient single-chip design and a large 256-byte transit/receive FIFO buffer that work together to provide high-speed serial communication while reducing the overall load on the system CPU.

With the included standard and low profile/half-height brackets, this PCI serial expansion card suits a broad range of system form factors, and is a perfect addition for connecting RS422/485 serial devices to a host computer. For added versatility, the RS422/RS485 adapter is able to accommodate 3.3 or 5V PCI/PCI-X slots.

Backed by a lifetime warranty and free lifetime technical support.


  • Much larger FIFO buffer than standard serial cards (256 byte vs. 32 or 64 byte) minimizes data loss and optimizes host efficiency
  • A simple jumper change allows you to select either RS422 or RS485 serial interface formats specific to your application
  • Standard and low profile/half-height bracket included, ensuring easy installation into almost any system


  • Supports maximum data transmission rate of 128Kbps
  • 16C1050 UART with 256-byte Deep FIFO
  • Supports 2-wire and 4-wire RS485 modes
  • Jumper pins for RS422/485 toggling
