NPort 5100 Series Quick Installation Guide
Adjustable pull high/low resistor for RS-422/485
(150 KΩ or 1 KΩ)
NPort 5100 Series
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 KΩ
setting with RS-232 mode,
since doing so will degrade the
RS-232 signals and shorten
the communication distance.

Third Edition, January 2011
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.

2. Package Checklist
Before installing the NPort 5100 series device server, verify that
the package contains the following items:
•
•
•
•
•
1 NPort 5100 series 1-port serial device server
4 stick-on pads
Documentation and software CD
Quick Installation Guide
Warranty card
Optional Accessory

3. Hardware Introduction
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.
LED Name LED Color

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.

STEP 1: After removing the NPort 5100 series device server from
the box, 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 2: Connect the NPort 5100 series device server’s serial port
to a serial device.
STEP 3: Connect the power adaptor.
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.
