Quick Installation Guide
Second Edition, June 2009
1. Overview
NPort 5100 series device servers are compact, palm-sized data
communication devices that allow you to control RS-232 (NPort 5110),
RS-422/485 (NPort 5130), and RS-232/422/485 (NPort 5150) serial
devices over a TCP/IP-based Ethernet.
Note: “-T” indicates an extended temperature model.

3. Hardware Introduction
As shown in the following figures, NPort 5100 series device servers have
one male DB9 port for transmitting RS-232 (NPort 5110), RS-422/485
(NPort 5130), or RS-232/422/485 (NPort 5150) serial data.

NOTE: The NPort 5110, NPort 5130, and NPort 5150 have the same
form factor.
Reset Button—Press the Reset button continuously for 5 sec to load
factory defaults: Use a pointed object, such as a straightened paper clip or
toothpick, to press 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, you should release
the reset button.
LED Indicators—NPort 5100’s top panel has three LED indicators,
which are described in the following table.

Jumpers are used to set the pull high/low
resistor values. The default is 150 KΩ. Short
the jumpers to set this value to 1 KΩ. Do not
use the KΩsetting with RS-232 mode, since
doing so will degrade the RS-232 signals and
shorten the communication distance.
4. Hardware Installation Information
STEP 1: After removing the NPort 5100 series device server from the
box, the first thing you should do is connect the power adaptor.
STEP 2: Connect the NPort 5100 series device server to a network. Use a
standard straight-through Ethernet cable to connect to a hub or switch.
When setting up or testing the NPort 5100 series device server, you might
find it convenient to connect directly to your computer’s Ethernet port. In
this case, use a cross-over Ethernet cable.
STEP 3: Connect the NPort 5100 series device server’s serial port to a
serial device.
STEP 4: Placement options
In addition to placing
the NPort 5100 on a
desktop or other
horizontal surface, you
may also make use of
the DIN-Rail or Wall
Mount options, as
illustrated here.
