NPort IA5000A

Quick Installation Guide

Third Edition, July 2013

Overview

The NPort IA5000A 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.

Hardware Introduction

The NPort IA5150A series has one RS-232 DB9 serial port and one
RS-422/485 terminal block for serial data communication. The
NPort IA5250A/IA5250A series has two/four RS-232/422/485
3-in-1 DB9 serial ports for serial data communication. Each model
has one 8-contact screw-type terminal block, which is 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.

Hardware Installation Procedure

STEP 1: After removing the NPort IA5000A 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 IA5000A series’ terminal
block, or connect the DIN-Rail power supply with the NPort
IA5000A series’ terminal block.

STEP 2: Connect the NPort IA5000A seri es to a network. Use a
standard straight-through Ethernet cable to connect to a Hub or
Switch. When setting up or testing the NPort IA5000A 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 IA5000A seri es’ serial port to a serial
device.

STEP 4: The NPort IA5000A 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 mount kit (optional)
first, and then screw the device onto the wall. The following figure
illustrates the two mounting options:
