NPort IA5450A Series

Quick Installation Guide

Third Edition, December 2010

1. Overview

The NPort IA5450A series device servers deliver easy and reliable
serial-to-Ethernet connectivity for the industrial automation
market. The servers support several operation modes—TCP Server,
TCP Client, UDP, Real COM, RFC2217, RTelnet, Pair Connection,
and Ethernet Modem—ensuring the compatibility of network
software, and are an ideal choice for connecting RS-232/422/485
serial devices, such as PLCs, sensors, meters, motors, drives,
barcode readers, and operator displays.

3. Hardware Introduction

Each model in the NPort IA5450A Series has four RS-232/422/485
3-in-1 DB9 serial ports for serial data communication, which are
located on the front of the unit, and there is an 8-contact
screw-type terminal block located on the top for power input and
relay output.

The Reset to Default Button—Depress the Reset to default
button for 5 continuous seconds to load the factory default settings:

Use a pointed object, such as a straightened paper clip or toothpick,
to depress the Reset to default button. This will cause the Ready
LED to blink on and off. The factory default settings are loaded
once the Ready LED stops blinking (after about 5 seconds). At this
point, you can release the Reset to default button.

4. Hardware Installation Procedure

STEP 1: After removing the NPort IA5450A series from the box,

the first thing you should do is connect the power
adaptor. Connect the 12-48 VDC power line with the
NPort IA5450A series’ terminal block, or connect the
DIN-Rail power supply with the NPort IA5450A series’
terminal block.

STEP 2:

Connect the NPort IA5450A series to a network. Use a
standard straight-through Ethernet cable to connect to a
Hub or Switch. When setting up or testing the NPort
IA5450A series, 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 IA5450A series’ serial port to a serial
device.

STEP 4:

T

he NPort IA5450A series is designed to be attached to a
DIN-Rail or mounted on a wall. For DIN-Rail mounting,
push down the spring and properly attach it to the
DIN-Rail until it “snaps” into place. For wall mounting,
install the wall m ou n t k it ( o ptional) first, and t hen screw
the device onto the wall. The following figure illustrates
the two mounting options:
