Introduction
Overview
The Secure Device Server provides security-assuring, IP-based LAN
connectivity for serial devices and supports a wide range of operation modes.
It empowers everyday serial devices — PLCs, meters, and sensors — to be
connected to a network, and allowing them to be accessed and managed from
anywhere over the network.
Equipped with extensive security features, such as Secure eal COM, Secure
TCP Client and Server, Secure Serial Tunneling, UDP, and Secure Console
Management, the Secure Device Server is the ideal solution for managing
serial device in a wide range of security-critical applications.
Fully compatible with existing serial communication software, the Secure
Device Server ensures that your former investments in software development
are protected. Software designed to work with COM or TTY ports can access
the serial devices connected over a TCP/IP network by utilizing the Secure
Device Server’s eal COM or TTY drivers. This feature also breaks through
the port number and distance limitation barriers encountered with PC
hardware.
With SSL and SSH protocol support — for encrypting data transmission — the
Secure Device Server ensures secured data transmission over both private and
public networks.
Installing the Secure Device Server is fast and easy: plugging cables into their
appropriate ports is all that is entailed. It also offers a browser-based GUI,
Telnet / SSH console sessions, and a Windows software utility, making
configuration and operation swift and smooth.
SN3001P / SN3002P / SN3401P / SN3402P provides PoE function, IEEE
802.3af compliant, thus can be powered through an Ethernet cable, by a PoE
switch/adapter, without requiring an additional power supply.
All in all, with its advanced features and ease of operation, the Secure Device
Server is the most convenient, reliable, and cost-effective way to remotely
manage your serial devices.
