Introduction

Thank you for purchasing the Embedded Data Systems OW-SERVER-ENET-2. The OW-

SERVER-ENET-2 provides an easy and simple method for the continuous monitoring of 1-Wire®

sensors that you might install in such places as computer server rooms or manufacturing facili-

ties.

The Embedded Data Systems OW-SERVER-ENET-2 product line features a lightweight, low-

power space saving design coupled with powerful on-board, web-based monitoring software.

Data from connected 1-Wire sensors is provided in open, industry-standard formats (e.g., XML,

SNMP) making it easy to integrate with existing business automation and monitoring systems.

This manual is divided into the following sections:

•Quick Start Guide—this section provides simple and easy steps to get up and running

quickly with your OW-SERVER-ENET-2

•Interface—this section describes the three interfaces (physical, web, and programmatic)

to the OW-SERVER-ENET-2

•Configuration—this section provides information on how to setup a OW-SERVER-

ENET-2 with your existing network and/or business systems as well as how to configure

attached 1-Wire devices

•Web Access—this section describes how to utilize the on-board web application to ac-

cess real-time monitoring of your connected 1-Wire sensors

•Integration—this section provides details on how to integrate the OW-SERVER-ENET-2

with existing systems and applications. This section is aimed at software programmers

and engineers who want to interface directly to the OW-SERVER-ENET-2

QUICK START GUIDE

Getting started with the OW-SERVER-ENET-2 is simple. Just follow a few easy steps:

1. Apply power to the OW-SERVER-

ENET-2. The green PWR/ACT LED

will begin to flash at one-second in-

tervals, indicating that the product is

operating normally. Power must be 5

volts at 400 milliamp (minimum).

2. Connect it to your Network. Con-

nect a live network cable to the

Ethernet Port on the device. The green LED on the Ethernet connector will illuminate, in-

dicating a valid network connection. The yellow LED on the Ethernet connector blinks on-

ly when there is network traffic.

3. Connect a 1-Wire Device. Connect a supported 1-Wire device to any of the 1-Wire RJ12

connectors.

4. Determine the IP address of the OW-SERVER-ENET-2 by checking your DHCP server

logs or using EDS Appliance Scanner Software1available from the EDS website. If the

OW-SERVER-ENET-2 does not find a DHCP server running on your network, it will de-

fault to the following IP address: 169.254.1.1.

5. Configure your device. Type the IP address of the OW-SERVER-ENET-2 into your

Web browser (e.g., http://192.168.1.27) and press enter. Select the tab “Network Setup”.

When the name and password is requested, enter “admin” for the name and “eds” for

the password. A Web page similar to the one shown to the right will enable you to config-

ure and monitor various aspects of

your OW-SERVER-ENET-2.

CONGRATULATIONS! You have

successfully installed your Embed-

ded Data Systems’ OW-SERVER-

ENET-2. Please refer to the Web

Access section of the Operation

Manual to obtain an understanding

of the function of each of the Web

pages served by the OW-SERVER-

ENET-2.

Some things to keep in mind:

•The OW-SERVER-ENET-2 has an internal flash drive that may be used to set it to a fixed IP address. See

the section Configuration/USB for more information.

•See section Additional Resources or EDSPRODUCTS.COM for a list of supported 1-Wire devices.

•No support is provided for OW-SERVER-ENET-2 IP address identification when utilizing any method other

than the EDS Appliance Scanner Software. Please consult your network administrator if you cannot locate

the DHCP address.

INTERFACE

The OW-SERVER-ENET-2 has three types of interface:

•Physical—the ports, buttons, and other elements on the unit itself

•Web—the on-board Web application that provides real-time access of monitoring data

•Programmatic—the methods by which to interface directly with monitoring data

Physical

The physical interface of the OW-SERVER-ENET-2 includes five parts:

•1-Wire Connector Panel: provides connectivity to 1-Wire sensors through three (3) RJ12

connectors. Each connector is a separate 1-Wire bus

•Power: a single micro USB connector.

The power connector also has a USB

port, which may be used to configure

the network settings. See section

Configuration/USB

•Ethernet: connects the device to an ex-

isting 10/100-baseT network via a

standard RJ45 connector

•Power/Activity Indicator: flashes green to indicate the unit is receiving power and operat-

ing correctly, flashes yellow to indicate data activity

USB

The power / USB port may be used to configure the network settings via the internal flash drive.

This method would typically be used to configure the network settings to a fixed IP address with

the DHCP server turned off, as shown below. See the section Configuration/USB below.

Web

Each OW-SERVER-ENET-2 includes an integrated Web-server that provides access to moni-

tored data from any Internet connected device such as a Web browser on your PC, smartphone,

or even an iPad®!

The Web interface provides you an easy way to configure the network setting for the OW-

SERVER-ENET-2 and is accessible by navigating to its IP address. When you connect the OW-

SERVER-ENET-2 to your network it will automatically request an IP address from an available

DHCP server if the feature is turned on, otherwise it will use an IP address assigned by you.

See configuration section below.

Simply open a Web browser and enter that IP

address to access the Web monitoring appli-

cation.

The Web interface provides the following

menu items:

•Home—the default, opening screen

that provides a snapshot of all connect-

ed devices, graphing of one value for

all connected devices and OW-

SERVER-ENET-2 basic information

EN-USERMAN OW-SERVER-ENET-2 V2.0 12.20.12

oIndividual Sensor Data—by highlighting and clicking an individual sensor listed

on the Home page, a user can access alarm settings, modify limits and graph up

to 3 different sensor values.

•Advanced:

oDetails—allows user to view detailed information about each device connected to

the OW-SERVER- ENET 2

oDetailed XML File—allows user to view complete XML File

•System Configuration:

oNetwork Setup—provides access to security and network configuration infor-

mation.

oPOST Client Setup—provides access to configuration fields for HTTP Post and

Proxy Server features

o1-Wire Interface Setup—provides access to configuration fields for activating di-

rect control of the 1-Wire bus via TCP using ASCII based command set

•Contact—provides contact information and website link

Note: If you don’t know the IP address being assigned to the OW-SERVER-ENET-2 by your

network, simply access your DHCP’s assignment or download the EDS Appliance Scanner

Software that will automatically find and display the IP address for any OW-SERVER-ENET-2 on

the network. For more information about the EDS Application Scanner software, see section Ad-

ditional Resources.

Note: If your network does not have a DHCP server, the OW-SERVER-ENET-2 will default to a

self-assigned address of 169.254.1.1. In the event of this situation, you will need to temporarily

re-configure your computer’s network settings to be on the same network as the OW-SERVER-

ENET-2 in order to talk to the device for the first time. Only when the OW-SERVER-ENET-2 is in

the same address space as your other computers can you access it using a eb browser.

Programmatic

Through a number of different channels, you can access the OW-SERVER-ENET-2 program-

matically to create integration with existing systems and network services:

•HTTP—service provides delivery of html and xml data files via http get command, and

firmware upload via http post

•SNMP—provides access to data from all connected sensors, and pushes SNMP traps to

remote listeners for alarming capabilities

•Telnet—service provides ability to monitor the internal activities of the OW-SERVER-

ENET-2 for diagnostic purposes

•UDP Broadcast—listener on port number 30303 will respond to properly formatted pack-

ets broadcast to this port number, allowing other devices and applications to discover any

OW-SERVER-ENET-2 that exists on the same network. For assistance in determining

the units IP address, see the section Additional Resources regarding EDS Appliance

Scanner Software

•1-Wire Interface—service provides a TCP client that implements a command/response

low level interface that may be used to directly control the 1-Wire bus

CONFIGURATION

Any configuration of your OW-SERVER-ENET-2 (with the exception of SNMP Traps) can be

carried out through the integrated Web application and, in some cases, the USB port. The on-

board, Web based tools provide a method to configure both the unit itself as well as any at-

tached supported 1-Wire devices. The USB port provides a way to configure the network set-

tings.

To access the configuration elements,

•Navigate to the IP Ad-

dress your network has

assigned to the OW-

SERVER-ENET-2. This

will open the Web inter-

face.

From the default Home screen,

you can access the System Con-

figuration tab using the top row

menu. Here you will find:

•Network (configuration)

•Post Client (configuration)

•1-Wire (configuration)

Network Configuration

The Network Configuration page displays a number of fields to configure the OW-SERVER-

ENET-2 operations within your network.

Note: In order to access this portion

of the Web tool, you will need a

username and password. The facto-

ry default settings are: user name =

“admin”, and password = “eds” (all in

lower case.)

You can configure the following as-

pects of the OW-SERVER-ENET-2:

•Device name—the factory

default is OWServer_v2-Enet.

However this is a user defin-

able name, maximum 24

characters. Alphanumeric

characters, dashes, periods,

spaces, colons and underscores are permitted. This flexibility allows you to distinguish a

device by its location or function for clarity. This field is included in the XML file.

EN-USERMAN OW-SERVER-ENET-2 V2.0 12.20.12

•User name—this is the user name, case-sensitive maximum 12 characters, used to ac-

cess the configuration sections of the on-board Web tool and the Telnet interface. Upper-

case and lowercase Alphanumeric Characters permitted. The factory default is "admin".

•Password—this is the password used to access the configuration sections of the on-

board Web tool and the Telnet interface. Uppercase and lowercase Alphanumeric Char-

acters permitted. The factory default is "eds".

•Password—confirm the password entered in the previous password field.

•Host Name—the factory default name for the OW-SERVER-ENET-2 is EDSOWSERV-

ER2. You can change the name but it is limited to 16 UPPERCASE characters. This field

is also included in the XML file.

•Enable DHCP—check this box to automatically enable the OW-SERVER-ENET-2 to re-

ceive an IP address and other network configuration information (such as gateway and

subnet mask) from a DHCP provider on your network. Note: this is the factory default set-

ting of the device. If you elect NOT to enable DHCP, you must manually provide network

adapter settings for the device:

oIP Address—a standard IPV4 address. Note: if you configure the device with an

IP Address that is NOT a part of your network IP-range or class you will be unable

to access the device unless connected directly to it with a computer configured

with the same IP settings

oGateway—the IP address of your network gateway

oSubnet Mask—the Subnet mask

oPrimary DNS—the IP address of the primary DNS server

oSecondary DNS—the IP Address of a secondary DNS server. Note: this is op-

tional

oHTTP Port—the port through which the OW-SERVER-ENET-2 will listen for in-

coming HTTP requests. Normally programmed to 80

•Save—when you have finished making settings, click the “Save” button to commit the

settings to the device. This will cause the device to reboot

Note: At the time of initial boot-up, the device will look for a DHCP server. If one cannot be

found, the following default configuration settings will be applied:

•IP Address: 169.254.1.1

•Gateway: 169.254.1.1

•Subnet Mask: 255.255.0.0

•DNS: 169.254.1.1

POST Client Configuration

The POST Client Configuration page of the Web tool allows you to configure the POST Client

and Proxy features of the OW-SERVER-ENET-2.

To configure POST Client

•Enable the feature by click-

ing the check box

•Select the URL of the

HTTP POST server. This

field requires a fully quali-

fied URL and may include

an alternate port number.

This example sets the port to 12391:

“http://www.embeddeddatasystems.com:12391/files/myfile.htm”

•Select how often to send the “details.xml” file

•Proxy server may be enabled by clicking the check box

•Set the Proxy URL to the appropriate address, which is typically obtained from the net-

work administrator. For example, if the proxy server is at 192.168.1.230, port number

8080, then the Proxy URL field would be programmed to http://192.168.1.230:8080. The-

se proxy parameters only apply to the POST Client feature, they have no effect on any of

the other features.

1-Wire Configuration

The 1-Wire Configuration

feature of the Web-tool al-

lows you to configure the 1-

Wire interface on the OW-

SERVER-ENET-2.

At this time, the only configu-

ration setting allowed is to enable direct TCP communication with the 1-Wire bus. This allows

you to send commands directly to 1-Wire devices connected to the system. It is ideal for solu-

tions developers looking to integrate the OW-SERVER-ENET-2 with 1-Wire devices not current-

ly supported at a high level or for legacy applications. For specific 1-Wire commands see Low

Level 1-Wire Communication Protocol in Appendix A.

To configure the port

•Click the “Enable” check box `

•Specify a port number through which communication will occur

•When you are finished, click the “Save” Button to commit the settings to the device
