1.0 INTRODUCTION
The PCI-COM232 family consists of one, two and four port, RS-232 compatible, serial I/O boards
designed to operate in computers with PCI bus accessory slots. The package includes complete software
drivers for Windows 95, 98, NT and 2000 that allow the boards to be installed as standard “COM” ports
in your computer.
The boards are fully plug-and-play and provide an independent UART for each port. The boards provide
data and all standard RS-232 handshaking signals. They operate up to a maximum baud rate of 460.8
kbaud. All connections in the one and two port boards are made through standard DB9M connectors
while the four port board can be ordered with either DB9M or DB25M connectors.
The available models are shown in the table below.
