NPort 5100 Series User’s Manual 

Choosing the Proper Operation Mode 

 

4-2

Overview 

NPort 5100 serial device servers network-enable traditional RS-232/422/485 devices, in which a 
serial device server is a tiny computer equipped with a CPU, real-time OS, 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 (RS-232/422/485) to collect 
data from various kinds of instruments. Since NPort 5100 Serial Device Servers network-enable 
instruments equipped with an RS-232/422/485 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 5100 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 won’t be limited by the host computer’s bus limitation (such as ISA or PCI), or lack 
of drivers for various operating systems. 

In addition to providing socket access, the NPort 5100 also comes with a Real COM/TTY driver 
that transmits all serial signals intact. This means that your existing COM/TTY-based software can 
be preserved, 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 speedier delivery. UDP also allows data to be unicast to 
only one IP address, or multicast to groups of IP addresses. 

Real COM Mode 

The NPort 5100 comes equipped with COM 
drivers that work with Windows 
95/98/ME/NT/2000/XP systems, and also TTY 
drivers for Linux systems. The driver establishes a 
transparent connection between host and serial 
device by mapping the IP:Port of the NPort 5100’s 
serial port to a local COM/TTY port on the host 
computer. Real COM Mode also supports up to 4 
simultaneous connections, so that multiple hosts 
can collect data from the same serial device at the 
same time. 

 

 

ATTENTION 

The driver used for Real COM Mode is bundled with NPort Administrator. The driver is 
installed on your computer automatically when you install NPort 5100 Administration Suite.
