NPort IA5150/5250 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 IA5150/5250 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.
NPort IA5150/5250 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, NPort IA5150/5250 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 unicast or multicast of data to only one IP or groups
of IP addresses.
