The Difference Between Device Servers,
Terminal Servers, and Console Servers
4
Secure Terminal Servers/Terminal Servers
The terms “terminal server,” “device server,” and “console server”
can be confusing. They all refer to hardware that connects to RS-232
devices and transmits serial data using TCP/IP Telnet, SSH, or a
vendor-specific protocol. In fact, these three server types represent the
evolution of user demand for information technologies.
Terminal servers were first introduced to help engineers connect
so-called "dumb terminals" to a host computer over an Ethernet
connection. With terminal servers, data transmission is text based and
is transmitted using Telnet, TCP/IP, SSH, or some other manufacturerdefined protocol. Terminal servers are designed to enable users
to access front-end IT equipment using PPP or dial-in/dial-out,
without using a modem. Terminal servers are generally found in IT
environments such as data centers, airports, and banks.
Before the development of Ethernet technology, terminal servers were
used to provide access to data using dial-up connections. However, as
Ethernet became more common, demand for industrial applications
also grew. Most machine-to-machine communication is serial-based,
which is effective only over short distances. This makes it difficult to
manage all equipment from a central location, which is the foundation
of industrial automation. Device servers emerged as a result.
A device server is essentially a simplified terminal server. For industrial
applications, serial-to-Ethernet communication does not require
sophisticated functionality. Device server manufacturers typically
include drivers or COM mapping functions that make things easier for
engineers who are not familiar with IT concepts. With drivers installed,
4-2
serial devices can be controlled over Ethernet using legacy software,
without requiring knowledge of difficult TCP/IP routing techniques
or socket programming. Engineers can continue relying on their
knowledge of COM/TTY port programming for device control.

As IT infrastructures quickly expanded, the "console server" or "serial
console server" developed as a management tool. Corporate MIS
decision-makers originally adapted terminal servers for use in central
management solutions. However, with the overwhelming adoption of
Ethernet, specific needs emerged for console servers. Management
security became a crucial issue, and console servers began requiring
advanced authentication functions. Moreover, to cope with everincreasing numbers of servers and routers, utilities and other solutions
have developed to simplify centralized management and reduce the
workload required.

Secure Terminal Servers
Overview
NPort 6000 device servers provide serial-to-Ethernet connectivity that
is more reliable and more secure. They can connect any serial device
to an Ethernet network using different operation modes such as TCP
Server, TCP Client, UDP, and Pair Connection mode. For applications
that require data security, such as banking, telecom, access control, or
Secure Data Communication with SSL Protocol
Network security is a critical issue for certain applications. Security
is especially important when data is transmitted over the Internet,
where it is vulnerable to interception by third parties. NPort 6000
device servers use SSL to implement secure modes for network data
security, including Secure TCP Server, Secure TCP Client, Secure
remote site management, secure modes are also available, including
Secure TCP Server, Secure TCP Client, Secure Pair-Connection, and
Secure Real COM mode.
Pair Connection, and Secure Real COM modes. The NPort 6000
and included drivers adhere to the SSL standard and automatically
negotiate the encryption key. To prevent hacker attacks, the NPort will
automatically switch from DES/3DES to AES encryption.

A powerful hardware encryption engine that supports the complete
DES/3DES/AES encryption algorithms is built into the NPort 6000. For
DES and 3DES encryption, the NPort 6000 supports ECB, CBC, CFB,
and OFB modes. For AES encryption, the NPort 6000 supports ECB,
CBC, CFB, OFB, and CTR modes with a 128-bit, 192-bit, or 256-bit key.

Power Redundancy with 802.3af PoE (Under Development)
NPort 6000 device servers can act as a PD (Powered Device) in
compliance with the 802.3af POE (Power Over Ethernet) standard.
This means that the NPort 6000 does not require a power adaptor, but
can operate using power supplied by a device acting as a PSE (Power
Sourcing Equipment).
Support for POE can also be used to for power redundancy. When
the power redundancy feature is enabled, the NPort 6000 relies on a
PSE for backup power. If the main power source (i.e., the power cable
or adaptor) fails, the NPort 6000 automatically continues operation
without interruption using power supplied by the PSE.

Port Buffering that Preserves Data if Ethernet Fails
4
Secure Terminal Servers/Terminal Servers
For mission-critical applications, data collected from a serial device
must be safeguarded if the Ethernet connection is severed. The NPort
6000 provides exceptionally reliable data transmission by saving serial
data to an internal 64 KB port buffer if the Ethernet connection fails.
Any Nonstandard Baudrate Between 50 to 921.6 Kbps
Most device servers support only standard baudrates. However, some
applications require special baudrates, such as 250 Kbps or 500 Kbps.
With NPort 6000 device servers, users can use any baudrate between
When the Ethernet is reconnected, data in the buffer is automatically
released and sent to the appropriate destination. For the NPort 6250,
6450, and 6650, this buffer can be expanded by installing an SD card.
50 and 921.k Kbps. The NPort 6000 works flawlessly with all devices
that require special baudrates.
Ethernet Port Expansion (NPort 6450/6650 only)
Although more and more devices are now Ethernet-ready, many legacy
devices only provide a serial interface. The main purpose of device
servers is to connect serial devices to Ethernet, allowing engineers to
integrate all devices into an Ethernet environment.
A problem can arise if both Ethernet-ready and legacy serial devices
need to be connected from the same location. The NPort 6450 and
6650 can use the Ethernet expansion module to add additional
Ethernet ports, effectively allowing operation as a combination Ethernet

switch/device server. With Ethernet expansion modules for the NPort
6450 and 6650, users no longer need to invest in a more expensive
switch or hub to connect every device. Modules are available for
different Ethernet media, including copper Ethernet, multi-mode fiber,
and single-mode fiber. Ethernet expansion modules can also be used
to create a cascading topology where device servers are connected to
each other in a daisy chain.

Supports ADSL Dial-up and DDNS
With serial devices connected to an NPort 6000 device server,
users can use any networked computer to control the devices over
an Ethernet network, intranet, or the Internet. Connections can be
established using different operation modes such as Real COM/TTY,
Reliable Power Input
TCP Server, or TCP Client mode. The NPort 6000 also supports PPPoE
for ADSL connections, and DDNS can be used to help locate NPort
6000 device servers on the network. In addition, fiber optic models are
available to extend the Ethernet connection distance.
NPort 6000 device servers have an industrial-strength power input
connector to minmize the chance of accidental power disconnection.
