Introduction

The PCI2S4851050 2 Port PCI RS422/485 Serial Adapter Card with 161050
UART adds two DB9 RS422/RS485 serial ports using a single PCI expansion
slot.

The serial card offers a high performance 16C1050 UART and is compliant
with PCI 2.3 local bus specifications. An efficient single-chip design and a
large 256-byte transit/receive FIFO buffer work together to provide high-speed
serial communication while reducing the overall load on the CPU.

With the included standard and low profile 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 RS422/485 adapter is able to accommodate 3.3 or 5V PCI/PCI-X slots.
