Chapter 1:
DataNet Overview

This chapter provides a general overview of the DataNet
system as well as the concept behind the ZigBee RF protocol.

1.1. DataNet Introduction

The Wireless Intelligent Logging Network

The DataNet system is a 16-bit, mobile data acquisition
network based on the innovative and reliable ZigBee
technology. This solution provides an intelligent sensor mesh
system with 100% data receipt and no data loss.

The DataNet system is comprised of a family of data logging
units, as well as a Receiver to manage the intelligent network
and Repeaters to extend the transmission range. The data
loggers measure a broad range of parameters and include
models that feature between one and four inputs for direct
measurement and recording of PT-100, thermocouple, 0-1 V,
4-20 mA, contact, frequency and pulse sensors, as well as
internal temperature and relative humidity sensors. These
models range from loggers with graphic display, AC or battery
power supply, to models with no display and battery power
only.

Data is transmitted from the end units to a Receiver
connected to a central computer. The system leverages the
ZigBee protocol, a 2.4 GHz license-free frequency RF band,
to ensure full data integrity. By adding DataNet Repeater units
to the network, you can extend the transmission range and
form a reliable mesh network of up to 65,000 units.

With its high resolution and fast Analog to Digital converter
(ADC), DataNet data loggers meet the majority of data
acquisition requirements in most industrial applications. Every

1

DataNet logger unit is embedded with a unique serial number
and can be loaded with a descriptive comment for safe
identification. An internal clock and calendar keeps track of
the time and date of every sample measured.

DataNet loggers can automatically activate external alarm
events when data is outside a specified range. Email and
SMS notifications can be sent to predefined contacts.

The DataNet system is powered by the powerful DataNet
software. The Windows ™ based software is the central
management interface of the DataNet network. Data is
monitored online and can be displayed in graphs or tables.
You can analyze data with various mathematical tools, or
export data to a spreadsheet.

The software also enables you to configure, calibrate or
update the firmware of DataNet units wirelessly.

Key DataNet benefits include:

• Reliable transmission ensuring no data loss

• Long-range monitoring

• Ability to constantly expand transmission range by adding

additional Repeaters, or turning loggers into Repeaters

• Portable units facilitating easy deployment in various

environments

• Remote programming and firmware updates

• 65,000+ possible end units

• 16-bit resolution

• Low-power consumption

• Long battery life

• Minimal costs thanks to wireless infrastructure

1.2. What is ZigBee?

ZigBee is a standards-based protocol built around the IEEE *

802.15.4 wireless protocol, providing the network
infrastructure required for wireless, low power network
applications.

The mesh network eliminates single points of failure by
providing multiple pathways for data to travel.

* IEEE is the Institute of Electrical and Electronics Engineers,

a non-profit organization dedicated to furthering technology
involving electronics and electronic devices.

1.3. The ZigBee Concept

The Coordinator: This device creates and maintains the

network. Once the network is up and running, the coordinator
behaves as just another device on the network. There is only
one Coordinator in a ZigBee network.

The Router: A router relays data packets/messages between

devices on the network and increases the distance between
these devices.

The End Unit: This device sends and receives information to

other devices on the network. It is usually a control or a
sensor unit, often battery operated. A ZigBee end unit cannot
relay messages.

ZigBee Terminology DataNet Terminology

Coordinator Receiver

Router Repeater

End Unit Data Logger

ZigBee enables mesh networking which supports a wireless,
yet integrated environment with communication between

3

many coordinators, routers and end units in environments
where multiple applications are being monitored.

1.3.1. ZigBee Mesh Network
Operation

Figure 1: ZigBee network diagram
In a mesh network, all the router units are aware of their

environment meaning a router knows with units are close by.

When a router sends a message to a specific unit, it relays the
message until it gets to the destination.

Network recovery from a unit failure

In a mesh network, when a router fails, the network
automatically finds a different path via a different router for the
message relay.

This ensures maximum protection against a network
breakdown.

1.3.2. Why is ZigBee Technology Key
for Data Logging?

ZigBee technology has proved to be ideal for data acquisition
networks which require meter reading, parametric display of
data such as temperature or humidity and responsive action
when parameters are crossed. This is due to the fully
automated, flexible and reliable nature of the protocol. With
the Mesh Network system, the ZigBee standard redresses

4

misbalances in any data logging system, responding to
weaknesses, inefficiencies, new network structure (with the
additional or removal of devices) through self correction.

1.4. The DataNet System

The basic DataNet system will contain at least one of the
following units:

• DataNet data logger – Part Number OM-DNL-910 or OM-
DNL-920

• Receiver/Repeater unit – Part Number OM-DNR-900

• Mini-USB cable

• Power adapter (one per DataNet unit ordered)

• DataNet Software CD

1.4.1. The Data Logger

There are two data logger models compatible with the

DataNet system. These are the so-called end units of the

system. These loggers support up to four external sensors
and two internal sensors, temperature and humidity,
depending on the specific model. Data is recorded and stored
to the logger’s internal memory and transmitted over the
network to the DataNet software running on the PC.

The data logger is programmed to consume as little power as
possible during operation, in order to conserve the battery life.

When not transmitting or recording data the units are in sleep
mode and they wake up when needed.

The battery is rechargeable and can run up to several months
on one charge, depending on the logger configuration. Refer
to section 3.7.5 for more information.

Note: Battery life depends on the logger sampling rate,

transmission rate, type of sensor, network architecture and
number of measured sensors.

1.4.2. The Receiver/Repeater

The OM-DNR-900 Receiver/Repeater unit can be
programmed by the user to work in either mode.

The Receiver acts as a bridge between the DataNet network

and the PC. It is connected to the PC via USB cable and is
used to create the network to which you add your data
loggers. The Receiver is externally powered but also includes
a rechargeable battery for back up (in case the external power
fails).

6

Note: Each Receiver can detect up to 8 data loggers and 16

Repeaters. To detect more data loggers, Repeaters are
required.

The Repeater is externally powered via the USB port but also

includes a rechargeable battery for back up (in case the
external power fails). These units are considered the
backbone of the network, as they enhance the network range
by receiving and transmitting the data from Repeater to
Repeater until the data reaches the designated end unit or the
PC.

The Repeaters are the end units’ parent units, meaning each

Repeater has specific end units under their responsibility

(their children). They route the transmissions to and from the

end units to the Receiver (or other Repeaters in the network).

Each Repeater holds the data sent to the end units while the
end units are in sleep mode. At a specific interval the end unit
wakes up and receives the data from its parent (Repeater).

Note: Each Repeater can detect up to 24 data loggers and 16

Repeaters including the parent unit. If the number of loggers
exceeds this capability, additional Repeaters are required.

Part Number: OM-DNR-900
Repeater Transmission Range: 800 m line of sight
End Units per Receiver: ~65,000

1.4.3. Hardware Accessories

The DataNet system includes the following accessories:

• Mini-USB cable for connecting PC to DataNet Receiver

• Power adapter to power DataNet Receiver, Repeater and

data loggers

1.4.4. DataNet Software

The user interface for the DataNet system, the DataNet
software CD is provided together with the DataNet hardware
and includes the following features:

• Network management

• Data display, management, storage and data diagnostics

• Alarm settings: Email and SMS notifications, visual and

audible alarms

8

• Wireless sensor definition

• Wireless sensor calibration

• Wireless firmware update (boot over the air)

• Automatic software update (via Omega server)

The software interface is described in detail in Chapter 4:.

Chapter 2:
DataNet
Implementation Guide

First time users of the DataNet system should read this
chapter before drilling down into the many features of the
system described later in the user guide. The Implementation
Guide will give you a clear understanding of the basic aspects
of setting up the system, and getting your network up and
running.

Once you are familiar with the technical aspects of setting up
the network as outlined in this chapter, please consult section

2.9 for the recommended approach to initial deployment of the

system.

Example

Below is a diagram depicting a supermarket deployment of a
DataNet system, illustrating how the devices may be
positioned to provide full coverage within the facility.

Figure 2: Example of DataNet network application

10

2.1. DataNet Network
Architecture

The DataNet network architecture consists of layers of loggers
and Repeaters, forming a mesh network monitored by the
Receiver unit connected to the workstation PC.

The basic architecture is as follows:

• Maximum nodes on network: 65,000

• OM-DNR-900 Receiver recognizes up to 8 loggers and 16

Repeaters

• OM-DNR-900 Repeater recognizes up to 24 loggers and
16 Repeaters (including parent unit)

• OM-DNL-910 and OM-DNL-920 in Short Range Repeater
mode (refer to section 2.8.5) recognizes up to 24 loggers
and 16 Repeaters

The diagrams below show the architecture of a typical
DataNet mesh network. Repeaters and loggers, which are
being used as Short Range Repeaters in Figure 4 (see
section), can be added to the network in order to extend the
range and improve its robustness. Each such device has end
units communicating with it, but this route may change as the
RF environment changes. This is the ZigBee’s self correcting
mechanism at play.

2.2. Pre-setup Requirements

Prior to commencing with the DataNet implementation you
must have the following requirements in place:

PC

• 24/7 availability

• Reliable AC power

• Sufficient hard disk space to store loggers’ data

• One free USB port

DataNet devices

• One OM-DNR-900 DataNet Receiver

• At least one DataNet logger OM-DNL-910 or OM-DNL-

920

• At least one OM-DNR-900 DataNet Repeater, depending
on your environment, for extended transmission

Mini-USB cable

The mini-USB cable connects the OM-DNR-900 Receiver to
the PC (and is supplied with the PC Suite software kit).

2.3. Launching the Software

1. Install the DataNet software on the PC workstation. Refer
to section 4.1: Installing DataNet Software on page 76 for
more details.

13

2. Once the software and associated components have
been installed, launch DataNet from your DataNet

desktop shortcut

3. The main DataNet window is launched. The default view

is called Map View.

Figure 5: Main DataNet window

4. Check for DataNet updates. Go to Help > Check for
Updates from the DataNet main menu to check for newer

versions of DataNet software and firmware released since
you purchased your system. For more details on the
Update feature go to Chapter 5: Updating DataNet
Software and Firmware.

.

14

2.4. Connecting the Receiver

1. Only once the DataNet software has been installed,
connect the DataNet Repeater unit (OM-DNR-900) to the
Omega-supplied power adapter.

Note: Only use adapters provided by Omega Engineering.

Use of the wrong adapter could damage your DataNet units.

2. Turn on the unit by pressing the Scroll button on

the front keypad. The unit will beep when turned on.

3. Verify that the unit is in Receiver mode by seeing the
following screen on the LCD:

DataNet Receiver

ID: 123.456.789

The ID will be unique to your Receiver network. If the unit
is in Repeater mode, switch it to Receiver mode. Go to
section 3.12 for more details.

4. Connect the mini-USB cable to the computer and to the
Receiver’s mini-USB port. The DataNet Receiver icon

will immediately appear in the top left corner of the

Map View.

Figure 6: Adding Receiver icon to Map View

15

A green icon indicates that the Receiver is online.

Note: If the Receiver is not recognized by the software try

connecting the mini-USB cable to another USB port on the

PC. Or select Network > Detect Receiver in the main menu.

Should you disconnect the Receiver’s USB cable or
power adapter (and the battery eventually dies), the

Receiver icon will be grayed out:

5. Go to Network > Form New Network. The Receiver will

then form a new network based on your RF environment
rather than use the network formed in the factory. This will
ensure optimal network performance. Refer to section 2.8:
Optimizing the Network for more details.

Check the DataNet network ID that was formed by the
Receiver by placing the mouse cursor over the Receiver
icon. The network ID as well as Receiver firmware version
and unit serial number is displayed.

Figure 7: Receiver tooltip

Note: You can move the Receiver icon elsewhere on the

screen by going to Tools > Lock Map View and unselecting

this option.

2.5. Adding the Data Logger to
the Network

Once you have connected your Receiver and established a
network you are ready to add data loggers and build your
system.

16

2.5.1. Charging DataNet Loggers

Note: Only use adapters provided by Omega Engineering.

Use of the wrong adapter could damage your DataNet units.

If the loggers will run from the battery supply make sure to first
charge each of the loggers for 16 hours before use in order
maximize the battery life. A fully charged battery can last
several months, depending on your logger configuration.
Refer to section 3.7.5 or more details on battery life.

If the loggers will run from the AC power supply, when first
connected to the AC adapter the logger will always initiate the
16 hour charge cycle.

Note: For loggers measuring data with the internal

temperature sensor, it is critical to note that during the charge
cycle the logger will heat up thereby causing the internal
temperature sensor reading to rise up to 10 ˚C above ambient
temperature. Once the charging process is complete, the
logger will cool down and the internal temperature sensor
readings will return to normal.

For loggers remaining connected to AC power, to prevent the
logger from heating up again following the initial charge cycle,

the logger will receive a one minute trickle charge each day

rather than stay continually charged. This is sufficient to
ensure the logger doesn’t self-discharge and will maintain the
logger’s full charge status.

Refer to section 3.7.3 for more details on the DataNet loggers’
power supply.

 Alarm delay

 Alarm pre delay

2. Select the sensors you wish to connect to the logger for
data acquisition. It doesn’t matter which order you select
the sensors. You may only have Input 4 selected, for
example, and Inputs 1 to 3 left unselected.

3. Select the sampling rate and transmission interval (rate at
which the data is transmitted from the logger to the
Receiver).

4. Unless you have Alarm levels you wish to edit (see the

Alarms Setup tab), click either Setup and Run (to send
the setup and immediately log data), or Setup Only (to

send the setup but only log data at your command).

5. If you selected Setup Only in step 4, right-click the
Logger icon and select Run from the context menu to

start logging data.

6. To stop the logger, right-click the Logger icon and select

Stop from the context menu.

Note: Running the logger clears the logger memory. All

previously recorded data will be erased when you begin a new
logging session.

2.7. Viewing Data

Once you run the logger, you have several ways of viewing
the online data that is being acquired.

• Online graph/table/statistics views

• Logger icon tooltip

23

• Sensor view

2.7.1. Online Data Views

Double clicking the Logger icon or selecting Display Data in

the Logger icon context menu will open the online graph.

This graph is updated in real-time with the newly recorded
data.

You can switch between Graph, Table and Statistics views to
view the data in different formats.

This tool-tip is updated with every newly recorded sample.

2.7.3. Sensor View

Click the Sensor View icon in the tool bar to switch to

this view. Here, you can monitor the data by viewing data
display of each individual sensor, rather than of each logger.

Figure 14: Sensor view

• If the sensor is in alarm, the sensor box will change color
from green to red (just as the Logger icon would).

• Double-clicking the individual sensor window will open the
data in the online Graph view.

26

Note: By going to Tools > Switch Sensor View Mode you

can reduce the size of the sensor window to display only the
sensor type and sensor data. Recommended for networks
with many loggers.

2.8. Optimizing the Network

This section outlines a number of features and suggestions for
optimizing the DataNet network and getting the best
performance out of the end units and parent units.

For example, when you first setup your network, you want to
ensure that the loggers are placed in the optimum position in
order to receive and transmit data to/from the DataNet
software.

Refer to the DataNet specifications to guide you on the range
of the DataNet units. With this knowledge, and based on the
layout of your facility, you should have a good idea of the
likely positional layout of your units.

2.8.1. Signal Test Utility

Rather than setup the system on a trial and error basis,

DataNet has a Signal Test utility built in to the logger

firmware, which gives you a clear idea of the strength of the
signal of each logger to the Receiver, and the quality of the
data link between Receiver and logger.

Perform the following test on each logger in your system while
deciding where to position the logger:

1. Using the Scroll button, scroll through the main menu on

the logger until you reach the following display:

Signal level:

Run test -> Menu

27

2. Press the Menu button to run the test.

The signal level and link quality will be displayed. As you
move the logger further away from the Receiver, you will
see these two parameters drop from a maximum of 100%.

When the logger is out of range of the Receiver, you will
see the following screen:

Out of range

3. To exit the Signal test, press the Scroll button.

2.8.2. Overcoming RF Obstacles

A universal issue concerning any wireless system is how to
overcome a hostile RF environment. DataNet’s ZigBee RF
protocol has been designed for these hostile RF environments
that routinely exist onsite. ZigBee can overcome competing
wireless noise and other problems communicating the data.
Its mesh networking capabilities allows it to re-route signal
traffic around temporary or permanent physical obstacles,
radio-frequency interference, Repeater error or other such
failures.

The robustness of the system is such that there is no single
point of failure, ensuring data recovery from end units on the
network.

Tips on overcoming RF barriers

• When first creating the network in the environment where
the loggers will be deployed, form a new network on the
Receiver. There may be local interference on the 2.4 GHz
free bandwidth. The ZigBee protocol, when forming a new
network, selects the least noisy channel (out of 16
available channels). Within this channel the units can
change RF slots (by hopping) but cannot move to other

28

channels while running. By running on a channel on a
network created in another environment e.g. in the office,
this channel may become noisy and therefore
transmission range may be less than expected.

• When placing units in an indoor or outdoor environment,
bear in mind that walls, furniture, metal objects, etc. limit
the RF coverage thereby reducing the range of the units.

• Add Repeaters (OM-DNR-900) in range of end units and
parent unit to enhance RF coverage and improve
robustness of network. Have as many alternative
transmission routes as possible in order to eliminate
single points of failure.

• When placing Repeater ensure it is not on the limit of its
range to the end unit or parent unit (Repeater or
Receiver), to avoid periods of unavailability due to
changing RF conditions.

• Add Short Range Repeaters (OM-DNL-910 or OM-DNL-

920) to overcome RF interference nearby to the loggers.

• The higher the Receiver is positioned the better reception
quality it will obtain.

2.8.3. Showing the Network Path

By going to Network > Show Network Paths in the DataNet

main menu, the software will show the actual path that the
system uses to communicate between Receiver and logger,
for all units in the system.

Figure 15: Showing network paths – Example 1
You can also select Show Path from the logger context menu

to display the individual path from the unit to the Receiver.

Using this option you can see exactly how the system is built.

29

Figure 16: Showing network paths – Example 2

The screenshot above shows a system of three loggers (red
squares) and two Repeaters (blue circles) transmitting to the
Receiver.

The arrows show the path between the units. Note that they
are bi-directional, meaning that the system is a two-way
system with units both transmitting and receiving data.

• A green path indicates a strong signal

• A yellow path indicate a medium strength signal

• A red path indicates a weak signal

2.8.4. Adding Repeaters to the
Network

Loggers which aren’t in range of the Receiver can transmit to
the Receiver via a Repeater/Short Range Repeater, which is

30

in range. As DataNet is built using mesh networking
technology Repeaters (OM-DNR-900) can be added to the
system to enhance the network range.

The Receiver/Repeater is the same device, just configured
differently from the main menu when turned on. Refer to
section 3.11.3 to learn how to switch the OM-DNR-900 unit
type to Repeater.

2.8.5. Short Range Repeater

You may also enable a logger (OM-DNL-910 or OM-DNL-920)
to operate as a Repeater in addition to its logging capabilities.
In this mode the logger is referred to as a Short Range
Repeater (SRR) as the unit’s range specification stays at 80
m line of sight and is not increased to the longer range spec of
the Repeater.

To switch a logger to SRR mode, simply right-click the logger

icon in the DataNet software Map View and select Enable

Short Range Repeater Mode.
Note: In SRR mode the logger must be connected to AC

power at all times as the power consumption is much greater.

31

2.9. Recommended Approach to
Deploying DataNet Units

Now that you have a general understanding of how the
DataNet system functions, you may wish to follow the
recommended approach for initial deployment of the system.
This approach will ensure a smooth and efficient deployment
of your DataNet units and you may then tweak this approach
based on experience you gain while using the system.

Note: When deploying the system bear in mind that several

factors could cause interference with the system, such as
electromagnetic pulses, metal shielding in the vicinity of the
transmissions, other devices using the same 2.4 GHz band,
etc. Be familiar with your environment before deploying the
system. Also refer to section 2.8.

1. After you have charged the DataNet units and are ready
to deploy them in your facility, collect all units - data
logger end units, Receiver and Repeaters (if relevant) –
and bring them to your PC workstation.

2. Connect the Receiver to the PC and form a network. Turn
on the units and one by one bring them online so you can
view their icons in the DataNet software’s Map View.

3. Configure each of the units via the Setup feature. At this
stage it is not necessary to configure the type of sensors
you will be using, or sample rate, alarm levels, etc. The
point of this step is to configure each of the units with a
logger or Repeater name that indicates where in your

facility they will be deployed. For example, Room 15
Freezer or Floor 2 Bio Lab. This will make it much easier

for you to recognize the units in the Map View once you
have deployed them. Once in place, you can reconfigure
the units however you like.

32

4. It is also recommended, if possible, to change the Map
View default background to a diagram or map of your
facility. You can then move the logger or Repeater icons
accordingly so you can have a visual representation of
their location in the facility.

5. Take each logger and begin to distribute in your facility in
the precise location you would like them to be based.
Once in position you can then run the Signal Test on each
logger to verify that you have a good signal to the
Receiver. If you are out of range and there is no
alternative location for the logger, you will most likely have
to add at least one Repeater to the network.

6. Once each of the loggers is in position return to the PC
and in Map View, verify that each of the loggers is online.

You can also use the Show Network Paths feature to

see the path of the logger to the Receiver, and the
strength of the transmission.

7. If you determine that you need to add Repeater/s to the
network in order to bring end units online or enhance the
transmission where the signal is weak, then deploy the
Repeater/s with the following points in mind:

a. There must be an electrical socket accessible at the

location of the Repeater as they must be powered
externally in order to run for more than a few hours.

b. Place the Repeater/s as high from the ground as

possible in order to enhance the wireless signal from
its antenna.

c. Expose the Repeater/s to as many end units as

possible. For example, if there is a room with several
offline end units requiring a Repeater, position the
Repeater next to the room so that it is in range of as
many of these end units as possible, so you don’t
have to add more Repeaters.

8. After you have deployed the Repeater/s return to the
software and using the Show Network Paths feature verify
that all end units are now successfully transmitting to the

33

Receiver, either on their own or via a parent Repeater.
You can continue to tweak the position of the units until
you are satisfied with the quality of the transmission.

9. Now that the units are in place the last step of initial
deployment is to reconfigure each unit to start data
acquisition. Configure the sensor setup, sample rate,
transmission rate, alarm levels, Email/SMS notifications,
etc. as you see fit.

3.5.5. Programming Limitations for
OM-DNL-910 and OM-DNL-920

The standard sampling rate for all sensors on all inputs is from
a maximum of one sample every second to a minimum of one
sample every two hours. However, there are certain
limitations using a specific combination of sensors, which

41

must be taken into account when programming the DataNet
data loggers.

Note: The software integrates all programming limitations

automatically when configuring the loggers.

3.5.6. External Alarm Output

The DataNet system supports connection of an external alarm
e.g. siren, audible alarm, to the Receiver external alarm input
or to In-1 of the OM-DNL-910 and OM-DNL-920 data loggers.

42

When connected to the Receiver, the external alarm will be
activated whenever a logger on the network is in alarm status.
When connected to the data logger, the external alarm will be
activated only when that specific logger is in alarm status.

Once there is no alarm status, the external alarm will be
deactivated.

Data Logger External Alarm

In-1 of the OM-DNL-910 and OM-DNL-920 serves either as a
standard sensor input or as an external alarm output.

Configure In-1 as Alarm Normally Open or Alarm Normally

Closed in the logger Setup window in the DataNet software.
Normally Open will result in the alarm being activated during

alarm status (the circuit will be closed).

Normally Closed will result in the alarm being activated when

logger is not in alarm and therefore deactivated when there is
an alarm (the circuit will be opened).

Connect In-1 to your external alarm device.

Use the Alarm Setup tab in the Setup dialog to define the

logger alarm settings. If these settings are breached then the
alarm will be activated.

Receiver External Alarm

By connecting the external alarm to the Ext Alarm input on

the Receiver, any alarm on the entire network will activate the
external alarm.

Use the Alarm Setup tab in the Setup dialog to define the

logger alarm settings. Whenever the Receiver receives an
alarm status from any logger on the network, the external
alarm will be activated. No additional configuration in the
software is required.

3.5.7. Polarity

Current, voltage, thermocouples and user defined sensors
have distinct polarity. Be careful to connect them in the right
polarity.

44

3.5.8. Frequency/Pulse Counter

Connect the signal wires to In-4 terminal blocks, and select

Frequency or Pulse counter for Input 4 from the logger

Setup window in the DataNet software. Inputs 1 to 3 are still
available for other sensors.

The Frequency/Pulse counter is optically isolated from the
internal circuitry and can simultaneously measure a signal
source, together with another input.

3.5.9. User Defined Sensors

DataNet provides a simple and straightforward tool for
defining a limited number of custom sensors. Almost any
sensor or transducer with 0 – 1 V or 4 – 20 mA output is
accepted by the DataNet logger and its electrical units are
automatically scaled to meaningful user-defined engineering
units.

The sensor definitions are stored in the logger’s memory and

are added to the sensors list. The sensor’s readings are
displayed in the user defined units only in the DataNet
software. Future versions will also support displaying the user
defined engineering units on the logger LCD.

Refer to section 4.5.1 for more details.

3.5.10. Sensor Alarms

Via the software, users can define minimum and maximum
alarm levels for each input individually. Users can define pre­low and pre-high alarm levels, for an additional level of safety
in case the logger is approaching an actual breach of alarm.

45

The DataNet logger display indicates when the sensor reading

is in alarm of any type. The symbols AL-H, AL-L, AL-P-H or
AL-P-L are visible next to the corresponding input readings.

Refer to section 4.13 for more details.

3.5.11. Sensor Calibration

The DataNet data logger is shipped fully calibrated. However,
further calibration can be applied via the DataNet software.
The calibration parameters are sent to the data loggers
wirelessly and stored in the logger’s memory.
Users may calibrate individual input as well as all inputs at
once. Calibration settings may be saved and then loaded into
the logger at a later date if the calibration settings have
changed.

Refer to section 4.13.4 for more details.

3.6. Unit Serial Number and
Comment

Every DataNet data logger and Receiver/Repeater unit is
embedded with a unique serial number.

The data logger only can be loaded with a descriptive
comment to identify its task and location. You may add or edit
the comment of any logger on the network via the DataNet
software.

Every time data is transferred to the computer it is labeled
both with the logger’s serial number and comment and is
displayed in the graph or data table view.

The unit serial number is also marked on a sticker on the back
of the product.

46

3.7. Power Supply

3.7.1. OM-DNR-900 in Receiver Mode

The Receiver unit is powered via the USB port of the PC,
when connected via the mini USB cable. In addition, the unit
can run for a limited time (up to three hours) from an internal
NiMh rechargeable battery. To charge the internal battery,
connect the unit to the AC power supply supplied with the
OM-DNR-900. The internal battery pack is generally used as
a back up power supply in the event the external power
supply fails.

Note: When in Receiver mode, the unit must be connected to

external power at all times. While running on internal power,
the unit will run for only several hours before shutting down
and therefore shutting down the DataNet network which the
Receiver is managing.

3.7.2. OM-DNR-900 in Repeater Mode

When in Repeater mode, the OM-DNR-900 must be
connected to external AC power at all times using the
supplied AC charger. Otherwise, when the internal backup
batteries drains and shuts down the unit, all the end units
dependent on the Repeater to transmit to the Receiver, will
not be detected by the software. The user won’t be able to
monitor data readings from these units until the Repeater
comes back online.

When connected to external power supply, the Repeater
battery will not be charged when the unit is turned off. This will
allow the system to protect the battery from overheating.

3.7.3. OM-DNL-910 and OM-DNL-920
Data Loggers

The OM-DNL-910 and OM-DNL-920 data loggers run from an
internal NiMh rechargeable battery as well as from external
AC power supply. Depending on the logger configuration,
from a fully charged battery, the data logger can run for up to
several months. Refer to section 3.7.5 for more details on
battery life.

Note: Charge the data logger units for 16 hours before using

them for the first time.

When connected to external power supply, the data logger
battery will not be charged when the unit is turned off. This will
allow the system to protect the battery from overheating.

First Time Charging

From a fully drained battery, you must charge the battery for

16 hours to bring it to a full charge. Once the charge cycle is

complete, the logger will run from the external power supply,
without draining (or charging) the internal battery. In order to
maintain a fully charged battery and ensure the battery
doesn’t self-discharge, the battery charger will daily charge
the unit for a minute to maintain the battery capacity.

Note: Before storing the DataNet units make sure you have

unplugged all the sensors and turned the units off via the
keypad.

Standard Charging

Whenever a logger is reconnected to the charger it will begin
the 16-hour charge cycle, no matter what the status of the
battery. Once the charging cycle is complete the logger will
run from external power supply.

48

Effect of Charging Battery on Temperature
Sensor

For loggers measuring data with the internal temperature
sensor, it is critical to note that during the charge cycle the
logger will heat up thereby causing the internal temperature
sensor reading to rise by up to 10 ˚C above ambient
temperature. Once the charging process is complete, the
logger will cool down and the internal temperature sensor
readings will return to normal.

For loggers remaining connected to AC power, to prevent the
logger from heating up again following the initial charge cycle,

the logger will receive a one minute trickle charge each day

rather than stay continually charged. This is sufficient to
ensure the logger doesn’t self-discharge and will maintain the
logger’s full charge status.

3.7.4. Power Adapter

The DataNet power adapter is used to power the OM-DNR­900 and OM-DNL-910 and 920 units. The mains adaptor
(AC/DC adaptor) converts mains power (from a wall outlet) to
a voltage suitable to the DataNet hardware unit.

• Output: Capacitor filtered 9 to 12 VDC, 300 mA

• Female plug, center negative

Note: Only use Omega-supplied power adapters to avoid

damaging the units with incorrect power supply.

3.7.5. Data Logger Battery Life

Battery life depends on the logger sampling rate, transmission
rate, type of sensor, network architecture and number of
measured sensors.

• OM-DNL-910 and OM-DNL-920 can last up to six months
on a charged battery.

49

The table below provides two example scenarios of standard
logger configurations and expected battery life.

3.10. Operating the OM-DNL-910
and OM-DNL-920

This section explains how to operate the OM-DNL-910 and
OM-DNL-920 loggers and provides an overview of the menu
options on the units’ LCD screen.

3.10.1. Turning on the Unit

In order to view the logger menu options, the unit must be

powered on by pressing the Scroll button

Ensure the logger is charged or connected to the AC adapter.

Once the unit is switched on it will emit a short beep and the
screen will display a welcome message:

DataNet - OM
DataNet Logger

on the keypad.

3.10.2. Display Shutdown

If the logger screen is inactive for thirty seconds it will turn off.
However the logger will continue to operate in the

background. Press the Scroll button to enable the LCD

screen again. The screen will not turn off during firmware
upgrade.

3.10.3. Joining a Network

When a logger is powered on or reset, it will automatically
scan for a network after the welcome message has appeared.

There are three scenarios that can occur while scanning for a
network:

52

Scenario 1: The logger can’t find the last network that it was

connected to. For example, the logger is a new unit which was
never previously joined a network.

Scenario 2: The logger scans and finds the last network it

was connected to, and joins that network.

Scenario 3: The logger can’t find any networks at all.
Scenario 4: The logger found a network but failed to join. The

unit will try to reconnect nine times before scanning for the
network again. Moving the unit closer to the Receiver can help
the logger to join successfully. If the logger still can’t join, form
a new network.

Scenario 1

If the unit can’t find the last network that it was connected to
(for example, it’s a new unit), the unit will display all the
networks that are in range:

Scan for network

Where # is the number of networks found

Once the scan has been completed the following screen
appears:

Scan complete

Scan for network
Found # network

If more than one network was found, the user will need to
select the network ID that he wants to connect to. The user

uses the Scroll button to scroll through the Network IDs. The
relevant network is selected using the Enter button.

53

Network 1:

• Signal level: Indicates the reception level between end

unit and parent unit. If the level falls below 20% then the
logger should be placed in a better location or a Repeater
should be added.

• Link quality: Calculation of the data transmitted with no

errors from the logger to the parent unit. If the level falls
between 85% then the logger should be placed in a better
location or a Repeater should be added. The lower the
link quality %, the more retries are needed in order for the
logger to send all of its data.

58

Note: The signal level may be low but the link quality can still

be 100%.

You will not be able to run the Signal Level test when the
logger has lost its connection to the network. If you tried, then
the following screens are displayed:

• Logger – SR RPTR

Device is operating as a Short Range Repeater. Refer to
section 2.8.5 for more details.

Leave Network

If this option is selected, the unit will first leave the network
and then reset itself. The scan network procedure described
in section 3.10.3 will begin. The only exception to this
procedure is that even if the last connected network is found
during the scan, the unit will not automatically connect to it.

Leave network

Note: If the logger was in Run mode prior to sending the

Leave Network command the software will download all data
from the unit first and then force it to leave the network.

Reset Unit

When the unit is reset, upon start up it will automatically scan
for networks. The unit will automatically connect to the

60

previously connected network assuming it was found in the
network scan.

Following reset the unit will continue to operate according to
its last set up instruction. For example, if the logger was in
Run mode, then after reset it will continue to run and record
data.

Turn Off Unit

Selecting this option will shut the unit down. You can turn the

unit on again by pressing the Scroll button.

It is recommended to turn off the unit when it is not in use.

Turn off unit

Note: Turning off the logger when in Short Range Repeater

mode can have adverse affects on your network, as other
units may be dependent on the Repeater for transmitting its
data to the Receiver. To prevent the SRR from being a point
of failure if shut off, ensure the network is robust enough by
having alternative routes for the end units to reach the
Receiver.

Min/Max Values Menu

Each sensor’s minimum/maximum readings (taken from the
current logging session) will be displayed on two rows.

The first row indicates the sensor type, along with the
measurement units e.g. V, and the alarm indication if there is
an active alarm on this sensor.

The second row indicates the minimum and maximum
measured value and the units. H and L represent High and
Low values, respectively.

No Parent Signal/No Parent Found

When a logger’s parent unit, such as a Repeater or Receiver,
goes offline then the following screen is immediately displayed
on the logger:

No Parent signal

For example, this could happen if the Receiver managing the
network has formed a new network, so there is no Receiver
managing the previous network. Or if the parent unit is a
Repeater, and it goes offline, then the logger will display this
message.

Once it has determined that the parent signal is lost, it will try
to establish a connection with the network via another
Repeater but if it fails then the following screen is displayed:

Chapter 4:
Using the DataNet
Software

This chapter provides detailed description of
the DataNet software features, allowing you
to manage your DataNet network and
perform a variety of actions on your data
loggers, such as setup, calibration, defining
new sensors, managing Email and SMS
notifications, firmware updates and so on.

4.1. Installing DataNet
Software

Part of your DataNet package includes a DataNet software
CD. Follow the software installation instructions provided
below.

4.1.1. System Requirements

To work with DataNet your system should be configured
according to the following specifications:

Software

• Windows 2000 SP3, Windows 2003, Windows XP SP2,
and Windows Vista

• Internet Explorer 5.01 or higher

• Minimum screen resolution: 1024 x 768 (800 x 600 not

supported)

76

Hardware

• Pentium 800 MHz or higher

• 256 MB RAM

• 250 MB available disk space for the DataNet application

4.1.2. Installation Procedure

Please read these instructions before proceeding with the
installation process.

1. Insert the DataNet software CD into your computer’s CD
drive. The DataNet Installation Wizard automatically starts
running.

2. The Wizard first installs Microsoft .NET Framework 2.0.

The DataNet software requires this platform in order to
run. Follow the installation instructions to install the .NET
Framework on your PC. This step can take up to two

minutes to complete. Click Finish once installation is

complete.

3. The Silicon Laboratories USB driver installation will now
launch. The driver is necessary for the computer to detect
the DataNet Receiver hardware.

4. Follow the on-screen instructions to continue the
installation process. The default installation location is

C:\SiLabs.

7. Once installed click Finish to close the USB driver Install

Wizard dialog.

8. The main DataNet Installation Wizard now resumes.
Follow the installation instructions to install DataNet on
your computer. Once the installation process is completed

click Finish.

9. The DataNet software and components have now been
installed. Double click the DataNet shortcut on your

desktop

to launch the software.

10. Connect the DataNet Receiver to a USB port on your
computer. It will automatically detect the Receiver as new
hardware. After a few seconds you will see a message

79

stating that the device is ready for use. You may now
begin to configure your DataNet network.

4.1.3. Installation Troubleshooting

When connected to the PC USB port the Receiver was not
detected by the software.

Ensure that the USB driver was installed properly.

Go to Control Panel > Add/Remove Programs (in WinXP),

and check that the driver is installed:

If not, you should run the Silicon Labs setup file to install the
USB driver: CP210x_VCP_Win2K_XP_S2K3.exe setup.exe to
install the driver.

If the driver is installed, ensure that there is no other device
sharing the USB com port with the DataNet Receiver.

If you didn’t select the Launch CP210x VCP Driver Installer

checkbox during step 2 of the driver installation wizard (see
section 4.1.2), then the driver wasn’t installed. Run the wizard
again and be sure to select the checkbox.

4.2. DataNet Software Layout

This section provides an overview of the default DataNet
window view as well as a guide to all of the icons available
throughout the software.

The most commonly used tools and commands are displayed
on two toolbars. Tools that relate to all aspects of the program
are located in the main (upper) toolbar. Tools specific to the
graphs are located on the graph (lower) toolbar.
