NPort 5100A Series
Quick Installation Guide
First Edition, February 2010
1. Overview
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.
Note: “-T” indicates an extended temperature model.
2. Hardware Introduction
As shown in the following figures, NPort 5100A series device servers
have one male DB9 port for transmitting RS-232 (NPort 5110A),
RS-422/485 (NPort 5130A), or RS-232/422/485 (NPort 5150A) serial
data.

NOTE: The NPort 5110A, NPort 5130A, and NPort 5150A have the
same form factor.
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 5100A’s top panel has three LED indicators,
which are described in the following table.

Adjustable pull high/low resistor for RS-422/485 (150 KΩor 1 KΩ)

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 1 KΩsetting with RS-232 mode, since
doing so will degrade the RS-232 signals and
shorten the communication distance.
3. Hardware Installation Information
STEP 1: After removing the NPort 5100A series device server from the
box, the first thing you should do is connect the power adaptor.
STEP 2: 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 which case, use a cross-over Ethernet cable.
STEP 3: Connect the NPort 5100A series device server’s serial port to a
serial device.
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.
