Introduction

The SIO-485.LPCI, Item Number 7107, is a low profile PCI module that provides a single RS-422/485 serial
interface port. The board is designed using the OX16C950 UART, which features a 128-byte FIFO and
flexible clock prescalar (from 1 to 31.875), with support for 9-bit protocol and isochronous mode.
RS-422 provides excellent communications for long distance device connections up to 4000 ft., where
noise immunity and high data integrity are essential.
RS-485 is optimized for 'Multi-Drop' or 'Party-line' operations selecting data from multiple peripherals (as
many as 31 devices can be connected on an RS-485 bus).
The SIO-485.LPCI is designed to be used with a variety of Operating Systems including Windows, Linux, and
DOS. The SeaCOM API (Application Programmer Interface) included in the software for the SIO-485.LPCI
provides a variety of useful high-level function calls implemented as a Windows dynamic link library (DLL)
and as a Linux kernel module and library. In addition to the API, SeaCOM includes sample code and utilities
to simplify software development.
