Chapter 1: Introduction
The PCI Express Multiport Serial cards were designed for RS232, RS422 and RS485
asynchronous communications for use in a variety of applications. These boards were
designed to offer compatibility with the PCI Express bus and to be used by system integrators
and manufacturers in the design of industrial and commercial communication systems. The
card is available in 4-port and 2-port versions and is compatible with all popular operating
systems. Each COM port is capable of supporting data rates up to 3Mbps (460.8kbps in
RS232 mode is standard) and implements full RS-232 modem control signals to ensure
compatibility with a wide range of serial peripherals. Existing serial peripherals can connect
directly to the industry standard DB9M connectors or via RJ45 connectors. The board features
a x1 lane PCI Express connector which can be used in any length PCI Express slot.
