About this document:

This manual contains instructions for using the Ophir “EA-1 Ethernet Adapter” device.

The manual is divided into several sections:

Introduction to the EA-1 and general description of the product

Instructions for initial configuration and setup

Instructions for using the accompanying PC application

Instructions for using the device via user commands

Device specifications

Definition of Terms:

The word “device” used throughout this manual refers to the EA-1 adapter itself.

Instructions regarding computer control of the adapter (for example, opening a Telnet connection or using the USB

port) refer to a PC running Windows 7. Instructions for a PC running XP or newer versions of Windows are similar or

identical in most cases but minor variations may be required.

Note: It is possible to perform all these tasks using a computer running another operating system and not just with

Windows, for example a MAC or Linux PC, but in that case the instructions will be different according to the specific

operating system being used. All the tasks should still be possible using a different platform, as they are not specific

to Microsoft Windows (for example, Telnet and USB Virtual COM Port) but instructions are included specifically for

Windows as that is how the device and software have been tested.

Chapter 1 - Introduction:

This chapter provides some basic information about the EA-1 and a general description of the device.

General Description:

The EA-1 is an Ethernet Adapter intended for OEM customers. It is designed to work with standard or OEM Ophir

smart-plug sensors using a D15 connector. The EA-1 supports Ophir thermopile, photodiode, pyroelectric (PE-C) and

PD10 series sensors.

The EA-1 device is supported by a special PC Application “OphirEthernetApp” or by Ophir’s StarLab software package.

Physical connections to the device are as follows:

On the rear panel:

Mini-USB input, used for configuration and factory calibration

RJ-45 connector to Ethernet

12-24v DC power input socket, using standard Ophir connector (mating with 2.1/5.5mm axial plug)

On the front panel:

D15 socket to Ophir smart-sensor plug

On the sides:

Two M3 mounting holes are provided along each side of the device allowing attachment of an optional

bracket (as shown in the illustration above). The bracket makes it easier for the customer to attach the

device into his mechanical system. A set of two brackets and four screws are supplied with the device.

Full device specifications are included in Appendix A below.

Package Contents:

The EA-1 package includes the following items:

EA-1 adapter

Ethernet cross cable (for initial configuration)

USB-A to USB-Mini-B cable (for initial configuration)

Ophir 12v DC power supply

2x mounting brackets, 4x M3 screws for attaching the brackets to the device, 1x Allen Key

The “OphirEthernetApp” PC application and drivers for using the USB Virtual COM Port are available on the Ophir

website, www.ophiropt.com, search for “EA-1” and “Software”.

The device can be powered either via ‘Power over Ethernet’(PoE) if available, or via the 12-24v DC input.

Connection Protocols:

There are four ways to connect to the device:

Telnet

HTTP

UDP

USB Virtual COM Port

Telnet:

A Telnet connection can be used to send commands and receive back replies from the device. The connection is

established by using the device’s IP address. The host device (for example, a PC) is the “client” and the EA-1 device is

the “server”. This type of connection can be used manually from a Telnet terminal, or can be programmed into the

user’s software application to add automation, in much the same way as using a COM port. This type of connection

protocol is used in the “OphirEthernetApp”PC application to control the device. Details are listed later on in this

document.

HTTP:

Using a web browser, a connection can be established to the device which allows basic configuration, sending

commands, monitoring power from the sensor, and viewing general information about the device. The user needs to

enter the IP address in the browser and a connection is made to the device. A top level “web-page” is displayed with

several buttons that allow entry into several lower level pages. In addition, there is an option to send software

commands directly using the HTTP protocol. As for the Telnet connection, the host device is the “client” and the EA-1

device is the “server”. Details are listed later on in this document.

UDP:

For situations where Telnet is not available (for example - working with some PLCs) another option is to connect to

the device using a UDP connection. A special protocol is defined for working with UDP, see details below in the

section "Details of User Commands”.

USB Virtual COM Port:

A Mini-B USB connector is provided on the EA-1 device in addition to the RJ-45, to allow customers to connect to the

device separately from the Ethernet for configuration purposes. This connection can be used to query or set the IP

address for the first time, or to switch between dynamic and static IP address modes. For example, if the user is not

certain of the IP address of the device and therefore cannot connect via the Ethernet connector, they have the

option to connect via the USB port and query the IP address in an independent way from the Ethernet.

More details of using this connection are added below together with the basic configuration information.

This type of connection is supported also by the “OphirEthernetApp”software supplied with the device.

Ethernet Cables and Ground Connections to EA-1 Device:

See Appendix 3 below for information on what type of Ethernet cables are recommended to be used with the EA-1

device, and for information on issues of grounding and isolation.

Chapter 2 - Configuration:

Configuration of the EA-1 adapter is necessary before using the device for the first time. In particular, the IP address

(and other related settings) must be set. Two IP address modes are supported - static allocation (default) or dynamic

allocation (using DHCP).

In addition, the customer can optionally choose a “User Device Name” for the EA-1 adapter to make it easier to

identify the device on the network. This is particularly useful if there are several EA-1 devices connected on the

customer’s network at the same time.

This chapter describes how to set a static IP Address, how to change over to dynamic mode and how to change the

user device name. Several configuration methods are described in detail, including using the “OphirEthernetApp”

provided with the EA-1 Adapter, if using a PC running Windows. The user can choose whichever method is most

convenient.

The last section in this chapter describes how to return the device to factory default settings.

Device Default Configuration:

The device is shipped with the following default configuration settings:

IP Address…………………………………………. 10.0.0.2

Subnet Mask………………………………....... 255.255.255.0

Default Gateway………………………………. 10.0.0.1

User Device Name……………………………. (blank)

IP Address allocation……………………….. static (DHCP disabled)

Note: The default IP address “10.0.0.2” is a special IP address reserved for connecting directly to the device via a PC

rather than via a network. In most cases it will not be possible to connect to the device via a network with this IP

address. Conversely, if the IP address is changed by the customer to a new value, for example 172.16.16.49 as in the

examples below, it will still be possible to connect to the EA-1 device directly from a PC, but only if the default

gateway setting on the PC is also set to the correct value, in this example 172.16.16.1. See Appendix 2 for more

details.

Choosing New IP address for EA-1 Device:

The first stage in the EA-1 setup is to choose a new IP address for the device. In order to choose a new IP address,

reference must be made to the network to which the device will be attached. Most networks have a subnet IP

address (the first 2 or 3 parts of the IP address) which is fixed for all the devices on the network. Consult with your

network administrator to obtain a suitable IP address for your device.

Alternatively, it is possible to choose a “dynamic” IP address (DHCP mode) which is allocated automatically by the

network. The advantage of doing this is that there is no need to choose an IP address by hand. The disadvantage is

that the user may not know what IP address has been allocated to the device and therefore it will be more difficult

to connect to the device “by hand” via a Telnet connection or otherwise. The OphirEthernetApp will be able to

search and find the device when using DHCP mode.

Setting up a static IP address using HTTP:

In order to set a new static IP address using HTTP, the device must first be connected directly to a PC via its network

port (RJ-45 socket) using the supplied cross-over cable, and a web browser opened to IP Address “10.0.0.2”

An IP address for the EA-1 adapter needs to be obtained from the network administrator; this example uses an IP

Address 172.16.16.49, Subnet Mask 255.255.255.0 (default), IP Gateway 172.16.16.1

Note: In order to connect to the device using a PC, it may be necessary to first set the PC to a static IP address.

Instructions for doing this are shown in Appendix 2 below.

The following page should be shown on the web browser once a connection is established for the first time:

Click on “Ethernet Properties” and the following page should be displayed (on the left):

Enter the new IP address, and click on “Save”. The following message will be displayed at the bottom of the

webpage:

The settings have been saved in the device EEPROM but will only become active after the next power up of the

device.

Before disconnecting, repeat the above process for the Subnet Mask and Default Gateway settings, and press “Save”

for each one. See example above (on the right).

Now the device should be powered down (if using PoE, disconnect the Ethernet cable; if using the 12v DC input,

disconnect the power cable). Reconnect the cable to power up the device again, and reestablish the HTTP

connection as above. The IP address to use for connecting the second time will be the new IP address entered above,

for example 172.16.16.49.

Note: At present there is no option to switch on DHCP (Dynamic IP address allocation) using a button, this can be

done using other methods, see below, or by typing the command “$ND 1” in the web browser from the “Standard

Command” page (see details for this command below).

Setting up a static IP address using Telnet:

If using a Telnet connection, the method is similar to the process described above for HTTP, except that a connection

must first be established using Telnet, and changing the IP address and other settings must be done manually by

sending commands.

In order to open a Telnet terminal on a Windows PC, the user should first check that Telnet is enabled on the PC.

Open “Control Panel”, then choose “Programs”, then choose “Turn Windows features on or off” (this requires

administrator privileges on the PC):

The “Windows Features” box will open; it might take a few seconds for it to be populated:
