Overview
The NPort IA5000A series of device servers delivers 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. They 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/IA5450A 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 at 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 adapter. 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 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 IA5000A Series, you might find it
convenient to connect directly to your computer’s Ethernet port. In this
case, use a crossover Ethernet cable.
STEP 3: Connect the NPort IA5000A Series’ 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:
Grounding the NPort IA5000A Series
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from
the ground screw to the grounding surface before connecting the
devices.
ATTENTION
1.
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
2.
A 4 mm2
conductor must be used when a connection to the
external grounding screw is used.
Software Installation Information
For the NPort’s configuration, the default IP address of the NPort is:
192.168.127.254. You may log in with the account name admin and
password moxa to change any setting to meet your network topology
(e.g., IP address) or serial device (e.g., serial parameters).
For software installation, download the relative utilities from Moxa's
website
https://www.moxa.com/support/support_home.aspx?isSearchShow=1
•Download the NPort Windows Driver Manager and install it as the
driver to run with Real COM mode of the NPort Series.
•Execute NPort Windows Driver Manager; then map the virtual COM
ports on your Windows platform.
•You may refer to the DB9 Male pin assignment section to loop back
pin 2 and pin 3 for the RS-232 interface to carry out a self-test on
the device.
•Use HyperTerminal or a similar program (you can download Moxa's
program, called PComm Lite) to test whether the device is good or
not.

The terminal block must be used with a 28 to 12 AWG (torque value 4.5
lb-in) cable with the devices.
Four cables are available as optional accessories that can be used to
connect the NPort IA5000A Series to RS-232 serial devices. For your
convenience, we show precise cable wiring diagrams for each of the two
cables.
