1 Introduction

Welcome to Moxa NPort 4511 Programmable Communication Gateway, a
compact palm-sized communications device that allows you to control
RS-232/422/485 serial devices over a TCP/IP Ethernet.

This chapter is an introduction to NPort 4511 and includes the following
sections:

NPort 4511 is a Programmable Communication Gateway (PCG) that provides a
stable, second stage platform for System Integrators (SI) or large-scale customers
to develop their own communication gateway functions and user interface.

The typical Communication Gateway (CG) is a special purpose server used to
transform between the serial and Ethernet interfaces. Communication Gateways
have one or more Ethernet port and one or more serial port, and are commonly
referred to as serial-to-Ethernet devices. Their main purpose is to provide serial
devices with a simple and straightforward means of connecting to an Ethernet
network. In this way, can transparently connect to a network, and can make use
of different types of transmission methods, including TCP Server, TCP Client,
and UDP.

1-2

Moreover, PCG’s most important function is to provide something that the
typical CG does not have—second stage program development. This gives the
developer more options for handling character streams, multipoint connections,
and data storage functions. Depending on the kind of program you write, your
PCG can be made into different types of Communication Gateway that can be
used for different types of applications.

The reset button can be used in two different ways, so it requires further
explanation.

To use the reset button, press continuously for:

a. 3 sec to erase the password

After 3 sec, the ready LED will flash on/off every half second. Release the
reset button at this time to erase password.

b. 10 sec to load factory defaults

After 10 sec, the ready LED will flash on/off every fifth of a second.
Release the reset button at this time to load factory defaults.

Housing

DIN-Rail

For many industrial applications, you will find it convenient to use the DIN-Rail
attachments, as shown below.

STEP 1: Use 2 screws per ear to attach DIN-Rail mounts to each of NPort

4511’s two ears.

⇒

STEP 2:
Insert the top of the DIN-Rail into
the top slot of the DIN-Rail mount.

STEP 3:
Push the bottom of NPort 4511 so that the
bottom of the DIN-Rail snaps into the
bottom slot of the DIN-Rail mount.

NOTE: The DIN-Rail mounting kit is an optional accessory.

To remove NPort 4511 from the DIN-Rail, simply reverse Steps 2 and 3 above
by grasping the bottom of the NPort 4511 unit with both hands, and then using
your fingers to pull down slightly on the bottom DIN-Rail mounts. This releases
the bottom of the DIN-Rail from the DIN-Rail mount.

1-7

Wall Mount

For many industrial applications, you will find it convenient to mount NPort
4511 on the wall, using two screws, as indicated below.

STEP 1:
Screw two screws, separated by 7.8 cm, into the wall. The heads of the screws

should be no greater than 6.5 mm in diameter, and the shafts should be no
greater than 3 mm in diameter. Do not screw the screws in all the way—leave a
space of about 2 mm to allow room for sliding the NPort 4511 unit’s ears
between the wall and the screws.

STEP 2:
Insert the two screw heads through the
large parts of the keyhole shaped
apertures, and then slide NPort 4511
downwards, as indicated.

STEP 3:
For added stability, simply tighten
the two screws.

To remove NPort 4511 from the wall mount, simply reverse Steps 2 and 3.

2Power Connection

We discuss the following topics in this chapter:

 Connecting the Power Adapter
 Power Status Check

Connecting the Power Adapter

Take the following steps to connect NPort 4511’s power adapter.

1. Plug the power adapter’s DC plug into NPort 4511’s DC-IN jack.

2. Plug the power adapter into an electrical outlet.

Note that there is no on/off switch. The server turns on as soon as the connected
power adapter is plugged into a live outlet. The red PWR light on NPort 4511’s
top panel will glow to indicate that it is receiving power.

Power Status Check

Use the PWR LED on NPort 4511’s top panel to see if it is receiving power. A
red light indicates that power is being received. The absence of a light indicates
that power is not being received. If the unit is plugged in, then an unlit PWR
LED indicates that something is wrong with the NPort 4511 unit’s operation.

3Ethernet Installation

We discuss the following topics in this chapter:

 Connecting to a Hub or Switch
 Connecting to a PC

Connecting to a Hub or Switch

For most applications, you will simply plug one end of your Ethernet cable into
NPort 4511’s 10/100BaseTX port, and the other end into a Hub or Switch that is
connected to your network. In this case, you should use a standard
straight-through Ethernet cable, which is readily available from many
commercial vendors. However, if necessary you can make your own cable by
referring to the following cable wiring diagram.

Connecting to a PC

In some cases, such as when configuring NPort 4511 or downloading software,
you may find it convenient to connect NPort 4511 directly to your computer’s
Ethernet card. To do this, you will need to use a cross-over Ethernet cable. This
type of Ethernet cable is harder to find, although you can make your own cable
by referring to the following cable wiring diagram.

In this chapter, we give the DB9 Female Connector Pinouts. The following
topics are discussed:

 Mini Adapter

Loopback Header

NPort 4511 comes with an RS-232 loopback header as a standard accessory. The
loopback header, which can be used to test NPort 4511’s data transmission,
connects the TxD pin to the RxD pin, the DSR pin to the DTR pin, and the CTS
pin to the RTS pin (see the RS-232 Pinouts and Loopback Tester section above
for the wiring diagram).

Mini Adapter

NPort 4511 was designed with a built-in D-shell female serial connector, which
most serial devices also have. In order to make it easier for our customers to
attach NPort 4511 to any serial device, a DB9 (male) to DB9 (male) mini
null-modem adapter is included as a standard accessory with NPort 4511.

4-3

Terminal Block

To ease wiring concerns, NPort 4511 now comes with a 9-pin terminal block as a
standard accessory, as shown below. The terminal block has a Male DB9
connector that can be used in conjunction with the mini adapter to connect
directly to NPort 4511 (note that the terminal block is wired pin-to-pin).

Another alternative is to use the Male DB9 to Female DB9 cable, included as a
standard accessory, to easily connect NPort 4511 to the terminal block, as shown
below.

5Operation Mode Settings

To make full use of NPort 4511’s hardware functions, you must first develop
your own customized program to be downloaded to NPort 4511. This allows you
to use NPort 4511 as a major component in your communications system. The
program is developed on a PC with a Turbo C or Borland C development
platform, and then downloaded to NPort 4511. NPort 4511’s Developing Mode
and Running Mode are designed to make this procedure as straightforward as
possible.
Refer to the NPort Programmable Communication Gateway Programmer’s
Guide and NPort PCG API Reference for information on how to develop your
NPort 4511 program.
In this chapter, we discuss the following topics related to NPort 4511’s
operation:

 DIP Switch Settings
 Operation Mode Introduction

 Developing Mode
 Running Mode

DIP Switch Settings

The top panel of NPort 4511 contains the following table, which shows how DIP
switch 1 (SW1) is used to select NPort 4511’s operation mode. SW1 is located
on NPort 4511’s front panel.

SW1 Operation Mode

OFF Running

Keep the following points in mind when setting the DIP switches.

 DIP Switch SW1 controls the function of NPort 4511’s Operation Mode.
 DIP Switches SW2 and SW3 are not functional.

Operation Mode Introduction

NPort 4511’s two Operation Modes are described in the following subsections.

Developing Mode

Developing Mode is used when configuring NPort 4511 and when developing
and/or downloading a program. The following functions are available when
NPort 4511 is in Developing Mode:

 Run/Stop NPort 4511’s program manually for testing and debugging
 Configure NPort 4511
 Download a program
 Monitor program behavior
 Upgrade firmware

Running Mode

Running Mode is used during NPort 4511’s normal operation. The following
functions are available when NPort 4511 is in Running Mode:

 Activate a program automatically after NPort 4511 is powered on
 Configure NPort 4511
 Download a program
 Monitor program behavior
 Upgrade firmware
