Overview
“-T” indicates an extended temperature model.
Notify your sales representative if any of the above items are
missing or damaged.
The operating temperature of the power adapter in the box is
from 0 to 40°C. If your application is out of this range,
use a power adapter supplied by UL Listed External Power
Supply (The power output meets SELV and LPS and rated 12
48 VDC, minimum current 0.73 A). Moxa has power adapters
with wide temperature range (
PWR-12150-(plug type)-SA-T series, for your reference.
NPort 5100A series device servers are compact, palm-sized data
communication devices that allow you to control RS-232 (NPort 5110A),
RS-422/485 (NPort 5130A), and RS-232/422/485 (NPort 5150A) serial
devices over a TCP/IP-based Ethernet.

package contains the following items:
• 1 NPort 5100A serial device server
• 100 to 240 VAC power adapter (excluding T models)
• 4 stick-on pads
• Quick Installation Guide
• Product Warranty Statement

Hardware Introduction
As shown in the following figures, NPort 5100A series device servers
have one male DB9 port for transmitting RS-232 (NPort 5110A), RS422/485 (NPort 5130A), or RS-232/422/485 (NPort 5150A) serial data.

same form factor.

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
232 mode, since
doing so will degrade the RS

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—The NPort 5100A’s top panel has three LED
indicators, described in the following table.

Hardware Installation Information
The operating temperature of the power adapter in the box is
from 0 to 40°C. If your application is out of this range, please
use a power adapter supplied by UL Listed External Power
Supply (The power output meets SELV and LPS and rated 12
48 VDC, minimum current 0.73 A). Moxa has power adapters
with wide temperature range (
PWR-12150-(plug type)-SA-T series, for your reference.
STEP 1: After removing the NPort 5100A series device server from the
box, connect the NPort 5100A 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 5100A 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 5100A 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 5100A on a desktop or other horizontal
surface, you may also make use of the DIN-Rail or Wall Mount options,
as illustrated below.

Software Installation Information
For the NPort’s configuration, the default IP address of the NPort is:
LAN: Static IP = 192.168.127.254; netmask = 255.255.255.0
You may log in with the default account and password (account:
admin; password: moxa) to change any settings to meet your
network topology (e.g., IP address) or serial device (e.g., serial
parameters). If you would like to apply the Real COM mode to your
application, you will need to install NPort’s driver on your desktop. You
may also refer to Moxa’s support website
