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

Embedded Data Systems, LLC; 2019 Fortune Dr., Lawrenceburg, KY 40342; Phone/Fax [phone] / 37
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
