1. Overview
NPort 5200A series device servers are compact, palm-sized data
communication devices that allow you to control RS-232 (NPort 5210A),
RS-422/485 (NPort 5230A), and RS-232/422/485 (NPort 5250A) serial
devices over a TCP/IP-based Ethernet.
Note: “-T” indicates an extended temperature model.
2. Package Checklist

3. Hardware Introduction
As shown in the following figures, NPort 5200A series device servers
have two male DB9 ports for transmitting RS-232 (NPort 5210A), or
RS-232/422/485 (NPort 5250A) serial data and have two 5-pin terminal
block ports for transmitting RS-422/485 (NPort 5230A).
Reset Button—Press and hold the Reset button for 5 seconds to load
factory defaults: Use a pointed object, such as a straightened paper clip or
toothpick, to depress the reset button. This will cause the Ready LED to
blink on and off. The factory defaults will be loaded once the Ready LED
stops blinking (after about 5 seconds). At this point, release the reset
button.
LED Indicators—NPort 5200A’s top panel has four LED indicators,
which are described in the following table.

Adjustable pull high/low resistor and terminator for RS-422/485
Remove the NPort 5230A/5250A’s top
cover and you will find DIP switches to
adjust each serial port’s pull-high, pull-low,
and terminator.
Do not use the 1 KΩ setting
with RS-232 mode, as doing so will
degrade the RS-232 signals and shorten the
communications range.
