1 Introduction
1.1 About This Document
This document describes the hardware specifications and the cabling
guide of the DirectPort universal PCI multiport serial cards. For software
and driver installation, please refer to the Software User Guide in the CD
included. You can also download documents including this document
and the Software User Guide from Sena Technologies home page at

1.2 DirectPort Product Family
The DirectPort product family of universal PCI multiport serial cards is
designed to provide flexible expansions of high performance serial ports
to the computers to meet the diverse and unique requirements easily
and cost-effectively.
The DirectPort universal PCI multiport serial cards are based on the PCI
Local Bus Spec 2.3. They automatically set the I/O addresses and the
IRQ numbers when ROM bios or the operating system starts.
All DirectPort serial cards support high speed serial speed up to 921.6
Kbps and are equipped with internal surge protection for maximum reliability.
They also have internal 256 byte deep FIFO for communication stability.
The DirectPort product family provides the wide range of hardware
combinations. Users can select different port counts among 2, 4 and 8
ports, different line interface between RS232 and RS422/485, and different
form factor between standard profile and low profile, to meet their specific
hardware requirements. The DirectPort product family also supports various
OS’s including Windows 2000/XP/Vista/7 and major Linux distributions to
meet today’s various software environments.

10 Regulatory Information
10.1 FCC Compliance Statement
This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and,
if not installed and used in accordance with the instruction manual, may
cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference
in which case the user will be required to correct the interference at his
own expense.
