The PCI2S4851050 2-Port PCI Serial Adaptor 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 Adaptor is able to accommodate 3.3 or 5V PCI/PCI-X slots. Backed by a StarTech.com lifetime warranty and free lifetime technical support. 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 Much larger FIFO buffer than standard serial cards (256 byte vs. 32 or 64 byte) minimizes data loss and optimizes host efficiency. Add RS422 and RS485 (2 or 4-wire) support to a Desktop, Server or Embedded system For use in industrial environments with serial networking devices, high speed modems, monitoring equipment, long distance communication devices and printers Ideal for commercial and industrial applications such as POS networks, ATMs, bank teller stations, and CNC based production lines Works for industrial process control and factory automation applications
