NPort 6000 Series

Overview

The NPort 6000 network-enables traditional serial (RS-232/422/485) devices. The serial device server is a tiny
computer equipped with a CPU and TCP/IP protocols that can bi-directionally translate data between the serial
and Ethernet formats. Your computer can access, manage, and configure remote facilities and equipment over
the Internet from anywhere in the world.
Traditional SCADA and data collection systems rely on serial ports to collect data from various kinds of
instruments. Since the NPort 6000 network-enables instruments equipped with an RS-232, RS-422, or RS-485
communication port, your SCADA and data collection system will be able to access all instruments connected
to a standard TCP/IP network, regardless of whether the devices are used locally or at a remote site.
The NPort 6000 is an external IP-based network device that allows you to expand the number of serial ports for
a host computer on demand. As long as your host computer supports the TCP/IP protocol, you will not be
limited by the host computer's bus limitation (such as ISA or PCI), nor will you be limited by the absence of
drivers for various operating systems.
In addition to providing socket access, the NPort 6000 also comes with a Real COM/TTY driver that transmits
all serial signals intact. This enables you to preserve your existing COM/TTY-based software without needing to
invest in additional software.
Three different socket modes are available: TCP Server, TCP Client, and UDP Server/Client. The main
difference between the TCP and UDP protocols is that TCP guarantees delivery of data by requiring the recipient
to send an acknowledgement to the sender. UDP does not require this type of verification, making it possible
to offer faster delivery. UDP also allows unicast or multi-unicast of data to one IP or groups of IP addresses.
The NPort 6000 also supports console management applications, including Reverse Telnet, as well as Reverse
SSH terminal modes. Reverse terminal modes enable you to connect to a server's console port through an IP
network for remote control and/or monitoring of that server.
The NPort 6000 supports standard SSL secure data access for Real COM/TTY mode, TCP server mode, TCP
Client mode, and Pair Connection mode. Data transmitted on the Ethernet will be well protected.

Guide to NPort 6000 Modes

On the NPort 6000, each serial port is independently configurable for a different mode with different settings.
For example, on the NPort 6450, an administrator can easily configure two ports for Real COM mode, one port
for Ethernet Modem mode, and one port for Reverse Telnet mode. Please refer to Chapter 7, Configuring Serial
Port Operation Modes, for detailed information and configuration instructions.

Device Control Applications

For device control applications, the NPort 6000 offers the following modes: Real COM/Secure Real COM mode
and RFC2217 mode.
