Introduction
This chapter provides an overview of the
features and capabilities.
ongratulations on the purchase of your new EtherSeries
C
DNP-3 Ethernet Gateway. Interfaces include one
10/100BaseT ethernet interface and two RS-232/422/485
serial9-pin interfaces. A version is also available with two
opto-isolated RS-422/485 interfaces.
The gateway allows serial DNP-3 RTUs to communicate and
interoperate with DNP/IP (either TCP or UDP) based
controllers. The DNP-3 standard protocol is an asynchronous
protocol designed to connect directly to computer asynchronous
ports. DNP-3 has been extended to operate over Ethernet using
the IP protocol suite. This gateway converts between the DNP3 IP protocol and DNP-3 Serial protocols transparently.
Normal operation would consist of one or more Ethernet based
computers functioning as DNP-3 Host and one or more DNP-3
slave devices (usually RTUs) connected serially to the gateway.
By using RS-485, multiple DNP-3 slave devices may be
connected to each of the two serial ports on the EDNP-3. If
using RS-232, one DNP-3 slave device may be connected to
each serial port.
The EDNP-3 is designed for mounting on a standard DIN rail,
or for direct mounting on a wall. For easy connection to your
LAN, the gateway supports 10BaseT or 100BaseT , half or full
duplex with auto-sensing or pre-configuration.

EtherSeries EDNP-3 Functions
The gateway allows serial DNP-3 RTUs to communicate and
interoperate with DNP-3/IP (either TCP or UDP) based
controllers. The DNP-3 standard protocol is an asynchronous
protocol designed to connect directly to computer asynchronous
ports. DNP-3 has been extended to operate over Ethernet using
the IP protocol suite. This gateway converts between the DNP3 IP protocol and DNP-3 serial protocols transparently.
The EDNP-3 enables one or more DNP-3 ethernet based
controllers to communicate with DNP-3 based serial RTUs. It
will not allow DNP-3 IP RTUs to operate with a serial DNP-3
controller.
Other Features
Dual Serial Ports
The EDNP-3 contains two serial ports. The two serial
ports are independent, and may be used with different
hosts and different serial protocol speeds as well as
different DNP-3 address ranges and timeouts.
Multiple Hosts
The EDNP-3 may communicate with multiple host controllers.
Upgradeable Firmware
Firmware upgrades are downloadable to the gateway. The
utility program required for this, and the actual firmware
upgrades, are available from your dealer. A Windows
95/98/XP/NT workstation is required to run the download
software.

Configuration Switch
There is a momentary action push button switch on the reart of
the unit behind a small hole. Pressing this switch places the
unit in configuration mode and is used only when configuring
the unit via the serial port, as explained in Chapter 3 Configuration. Return from configuration mode by exiting the
configuration menu or by power cycling the unit. This switch
may be depressed with a tiny screw driver or stiff wire. (A
straightened paper clip works nicely).
LED Indicators
There are six red LED indicators on the top panel.
LED Indicators
• The LAN LED is the Ethernet Status indicator. It is lit
when there is a valid 10/100BaseT Ethernet connection.
• This LED flickers off and on with activity on the Ethernet
(even if the activity isn't directly to this unit).
• The RUN LED flickers off and on with ethernet transmit
activity from the EDNP-3.
• The COM port Tx and Rx LEDs flicker off and on with
characters being transmitted or received through the
appropriate serial port.

Introduction
Package Contents
You should find the following items packaged with your
EtherSeries product:
• The EtherSeries Unit
• Power Adapter (or power supply)
• This User’s Guide
If any of the above are missing, contact your dealer
immediately.
Software Requirements
The EDNP-3 supports DNP-3 (either TCP or UDP) on the
Ethernet interface and DNP-3 serial protocol on the serial ports.
It may be configured using any terminal or terminal emulation
software on a PC via serial port one. Any standard telnet
program may be used to telnet to the unit for configuration, or
any standard web browser may be used for configuration once
the unit has a valid IP address configured. Since any terminal
program (including Microsoft Hyperterm) or web browser may
be used when configuring the unit, there is no supplied
configuration software.

Chapter 2
Installation
This Chapter details the LAN installation
process for the EtherSeries product.
Overview
The EtherSeries products may be configured via a serial port,
telnet, or web browser. Initially, the configuration of an IP
address must be performed using the serial port unless the
default IP address of 192.168.1.1 is appropriate for your
Ethernet network.
To use LAN based configuration, either Telnet or Web Browser
based, an IP address must be configured. The default value of
192.168.1.1 may not work with your network.
Terminal Mode configuration may be performed at any time,
and no IP address is required. See Chapter 3 for details.
Quick Start
Quick start instructions are on the next page. Installation is an
easy process that is basically… plug it in, configure IP,
configure DNP-3, and configure the serial ports.

Installation
1. Connect the Network Cable
The EtherSeries network interface is auto-sensing. Simply
connect your network cable to the appropriate connector on
the rear panel. If you wish to configure ethenet options,
that may be performed later.
2. Connect the Power Adapter Cable
Plug in the power adapter cable. After about a 4 second boot
process the unit is ready for operation. Some configurations
require wiring to a screw-terminal block.
3. Configure IP Address Information
Using the default address and telnet or a web browser OR using
a serial port and terminal emulation, configure the IP and DNP3 ethernet information. At a minimum, the IP address and port
number must be configured.
4. Configure a Serial Port
Configure the appropriate serial ports for the proper DNP-3
protocol, slave address range, and timeouts.
5. Configure the DNP-3 Host.
You are now ready to use the EtherSeries Gateway. Configure
the DNP-3 host computer and the serial RTUs for proper
operation and start using it!

Terminal/Telnet
Configuration
This Chapter describes how to manage the
EtherSeries product using Terminal, or Telnet
mode. Web Browser mode management is
detailed in Chapter 4.
Overview
The EtherSeries unit may be managed using any of the
following methods:
• Web Browser - After installing the unit in your LAN, use
your Web Browser for management. See Chapter 4 -
Browser Configuration for details.
• Terminal Mode - Use a serial cable connection and a
communication program. This is often required prior to
other modes in order to configure a compatible IP address
into the unit.
• Telnet Mode - After installing the unit in your LAN,
manage it using Telnet.
Both Terminal and Telnet modes provide the same user
interface.

Terminal Configuration
Terminal configuration requires the following:
• PC with terminal emulation program, or a dumb terminal.
• Serial cable to connect the PC to the unit. See the
Appendix for cable requirements. A Crossover (null
modem) cable is required when using a 9-pin PC port.
• Serial port 1 must be configured as an RS-232 port. This is
the factory default configuration.
Procedure
1. Connect the unit to your PC or terminal.
2. Connect the unit to the power supply.
3. Press the configuration setup switch momentarily. It is
located to the side of the power connector and accessed
through a small hole. Use a small pen or paper clip to
access the switch.
4. Configure the terminal program with the following settings.
Setting Value
Flow control protocol None
Speed 9600
Data 8 bits
Parity None
Stop Bit 1
5. Configure your terminal program to the appropriate port
(e.g. COM 1).

Configuration
6. The configuration program should now start and after a
few seconds display a sign-on screen.
If nothing appears on your screen, press ESC.
Refer to the Terminal/Telnet Interface chapter for details
on using the configuration program.
Telnet Management
NOTE: To use telnet, there MUST be compatible IP
addresses in both the PC and the unit!
1. Install the unit into your LAN as described in Chapter 2.
Ensure that the unit is powered on.
2. Connect to it with the telnet program on your workstation.
A typical command is:
telnet IP_Address 8000
Where:
IP_Address is the IP address of the unit.
8000 is the management port number. For example, if the
default IP address has not been changed, then you would
enter the command:
telnet 192.168.1.1 8000
If you can't connect
If the unit does not respond, check the following:
• It is properly installed, LAN connections are OK, and it
is powered ON.
• Check that your PC is using a compatible IP Address
and Network Mask.
In Windows, using Control Panel-Network to examine
the Properties for the TCP/IP protocol can check the IP
