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

Fourier Systems next generation data logging system is the DataNet, 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 to 1 V, 4 to 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 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

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 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 DNL804, DNL808, DNL810, DNL910, DNL920

• Receiver/Repeater unit – Part Number DNR900

• Mini Repeater – Part Number DNR800

• Mini-USB cable

• Power adapter (one per DataNet unit ordered)

• DataNet Software CD

1.4.1. The Data Logger

There are five distinct 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 for the DNL910 and DNL920 is rechargeable and can run up to several months on one charge, depending on the logger configuration.

The battery for the DNL804, DNL808 and DNL810 is not rechargeable and can run up to ten months before being replaced, depending on the logger configuration.

Refer to section 3.9.6 for more information.

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

The five DataNet models can be divided into two groups:

• DataNet loggers (with LCD)

• Mini DataNet loggers (without LCD)

1.4.2. The Receiver/Repeater

Note: The DNR900 can work in one of two modes, Receiver

or Repeater. The DNR800 only works as a Repeater.

The Receiver, PN DNR900, 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).

Note: Each Receiver can detect up to 8 data loggers and 16 Repeaters. To detect more data loggers, Repeaters are required.

The Repeater is considered the backbone of the network, as it enhances the network range by receiving and transmitting between end unit and Repeater until it reaches the PC. There are two Repeater models, the DNR900 with LCD and the DNR800 Mini Repeater, without LCD. Both are externally powered via the AC adapter but the DNR900 also includes a rechargeable battery back up (in case the external power fails).

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.

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

• Wireless sensor definition

• Wireless sensor calibration

• Wireless firmware update (boot over the air)

• Automatic software update (via Fourier server)

The software interface is described in detail in Chapter 4:

Note: DataNet is also FDA 21 CFR Part 11 compliant. CFR compliant software must be purchased separately.

Chapter 2: DataNet Implementation Guide

Fourier Systems strongly suggests first time users of the DataNet system 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

2.8 2.9 for Fourier’s 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

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

• DNR900 Receiver recognizes up to 8 loggers and 16

Repeaters

• DNR900 Repeater and DNR800 Mini Repeater recognizes up to 24 loggers and 16 Repeaters (including parent unit)

• DNL910 and DNL920 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:

• 24/7 availability

• Reliable AC power

• Sufficient hard disk space to store loggers’ data

• One free USB port

DataNet devices

• One DNR900 DataNet Receiver

• At least one DataNet logger DNL910 or DNL920, or Mini

DataNet logger DNL808 or DNL810

• At least one DNR900 DataNet Repeater or DNR800 Mini Repeater, depending on your environment

Mini-USB cable

The mini-USB cable connects the DNR900 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 94 for more details.

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.

2.4. Connecting the Receiver

1. Only once the DataNet software has been installed, connect the DataNet Repeater unit (DNR900) to the Fourier-supplied power adapter.

Note: Only use adapters provided by Fourier Systems. Use of the wrong adapter could damage your DataNet units.

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

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 3.16 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

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.

2.5.1. Charging DataNet Loggers

This section refers to charging the DNL910 or DNL920 loggers. The Mini DataNet units are battery operated only.

Note: Only use adapters provided by Fourier Systems. 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 3.9.6 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 3.9.3 for more details on the DataNet loggers’ power supply.

2.5.2. Connecting DNL910 and DNL920 Loggers to the Network

1. Turn on the logger by pressing the Scroll button . The unit will beep when turned on. As soon as the unit is turned on, the LCD screen will display the following message:

Fourier Systems

Logger

2. The logger will then start scanning for networks. The LCD will indicate how many networks were found in range, and will announce when the scan is complete. Locked networks will not be listed.

Scan for network Scan for network

Found 2 networks

To join the network created by your Receiver (there may be other networks created by your colleagues) scroll through the found networks on the LCD (using the logger Scroll button)

Scan complete Scan for network Scan for network

Scan complete

and press the Enter button network. In the example below, the network required is the second network found. You can also rescan the networks by pressing Enter on the Rescan networks screen, which is reached by scrolling through all the found networks.

Network 1:

Network 1: ID: 014.061.082

ID: 014.061.082

Note: If the logger did not detect a network, the unit will turn off in order to conserve the battery.

3. Once you select the network, the logger will automatically join that network and a new message will be displayed on the LCD:

Joined network:

ID: 026.167.85

Note: If the message Join failed appears on the LCD, then rescan for the network and try again. If the logger continually fails to join, then form a new network on the Receiver.

when you reach the required

2.5.3. Connecting Mini DataNet Loggers and Mini Repeater to the Network

The Mini DataNet loggers (DNL804, DNL808, and DNL810) and Mini Repeater (DNR800) don’t have LCD screens therefore the process of joining these units to the network differs than that of the DataNet models with LCD.

Follow the steps below to connect these devices to the network.

1. In the main menu, go to Network > Device Filter to first define the Mini DataNet devices that are allowed to connect to the network. Enter the SN of each Mini DataNet device in the text window and click Add. Click Remove to remove a SN of a device you don’t wish to join the network.

Figure 8: Mini DataNet Device Filter dialog

If a Mini DataNet device tries to join the network but it is not in the list then the software will send the Leave

Network command to the device as it tries to connect to the network.

When a device tries to connect to a network and the software is down it will continue to the next available network. If the software is up either the software will accept it or it will send the Leave Network command.

2. Ensure the network is not locked. Go to the Network menu and uncheck the Lock Network menu item.

3. Take the first Mini DataNet device and give the button on the front panel a short press. The LED will blink orange until the network is found. Once the network is found, the LED will blink green three times. The device has now joined the network and the device icon will appear in the Map View.

4. Repeat Steps 1 to 3 for all Mini DataNet devices you wish to join to the network.

2.5.4. Loading Map View Background

Load an image into DataNet showing a map of your facility in order to place the Receiver and Logger icons in their relative positions. As you add more loggers to the system, this will prove very helpful.

• Double click the Map View background to browse to the image directory and load the image. Remember to unlock the Map View in order to move the icons around.

• Right-click the Map View background and two options will be available: Load Wallpaper and Reset Wallpaper, which resets to the default Fourier wallpaper.

Figure 9: Map View background image example

2.6. Configuring the Logger

Once you connected your DataNet loggers to the network, you must configure them in order to start acquiring data.

1. Right-click on the Logger icon you wish to configure. Select Setup from the context menu.

The Setup window will be launched.

Figure 10: Logger Setup window

This dialog provides non-editable information such as the serial number, battery level, reception level and firmware version of the current unit.

On the Device Setup and Alarm Setup tabs, the user is able to configure the following parameters:

 Unit's comment

 Sampling rate

 Transmission interval

 Samples averaging

 Temperature units °C/°F (on the logger LCD. Not

applicable for Mini DataNet loggers)

 Active sensors

 Custom sensors' names

 Alarm levels

 Alarm duration

 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

• 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.

Figure 11: Online data – Graph view

Figure 12: Online data – Table view

Figure 13: Online data – Statistics view

2.7.2. Logger Tooltip

Close the online data window and return to Map View. Scroll over the Logger icon and you will see a tooltip displaying the relevant logger information, including real-time data.

Figure 14: Logger tooltip

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 15: 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.

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

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 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 (DNR800 or DNR900) 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 (DNL910 or DNL920) 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 16: 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.

Figure 17: 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 in range. As DataNet is built using mesh networking technology Repeaters (DNR800 or DNR900) can be added to the system to enhance the network range.

The DNR900 Receiver/Repeater is the same device, just configured differently from the main menu when turned on. Refer to section 3.15.3 to learn how to switch the DNR900 unit type to Repeater.

The DNR800 only functions as a Repeater.

2.8.5. Short Range Repeater

You may also enable a logger (DNL910 or DNL920) 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.

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 use Fourier’s 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.

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 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.

3.7.4. External PT-100 and NTC Sensor Connection

The PT-100 (for the DNL910 and DNL 920) and NTC (for DNL808) sensors, as supplied by Fourier Systems comes prewired to the data logger’s terminal block.

The PT-100 positive polarity (red) and ground (white) wires are connected to the + input of the terminal block. The negative polarity (black) wire is connected to the – input on the terminal block.

3.7.5. Programming Limitations for DNL910 and DNL920

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

Note: The software integrates all programming limitations automatically when configuring the loggers.

3.7.6. 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 DNL910 and DNL920 data loggers.

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 DNL910 and 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.

Note: Maximum load of the Relay is 50 mA, 3 V.

Refer to Appendix A: DataNet Specifications for the full external alarm output specification.

3.7.7. Polarity

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

3.7.8. 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.

3.7.9. 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.

3.7.10. 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.

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.

3.7.11. 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.

3.8. 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.

3.9. Power Supply

3.9.1. DNR900 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 DNR900. 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.

3.9.2. DNR800 and DNR900 in Repeater Mode

The DNR800 must be connected to external AC power at all times. This device does not have an internal battery so when the external power supply is disconnected the unit will shutdown.

When in Repeater mode, the DNR900 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.

3.9.3. DNL910 and DNL920 Data Loggers

The DNL910 and DNL920 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 3.9.6 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.

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.

3.9.4. DNL804, DNL808 and DNL810 Data Loggers

The Mini DataNet loggers are powered by non-rechargeable internal 2/3 AA lithium batteries. There is no external power supply for these loggers.

Depending on the logger configuration, the battery can last up to 10 months before they need to be replaced.

Replacing the Mini DataNet Battery

To replace the batteries on the Mini DataNet loggers, remove the two screws located on the top panel of the logger (where the antenna is connected) and with care pull out the internal compartment containing the logger circuit board and battery. Remove and replace the battery, ensuring the correct polarity

of the battery, and push the internal compartment back into place. Secure the panel with the two screws.

Note: With the DNL808 also disconnect the external sensor to avoid damaging it.

3.9.5. Power Adapter

The DataNet power adapter is used to power the DNR900 and DNL910 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 Fourier-supplied power adapters to avoid damaging the units with incorrect power supply.

3.9.6. Data Logger Battery Life

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

• DNL910 and 920 can last up to six months on a charged battery.

• DNL808 and 810 can last up to 10 months on a new battery.

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

3.12. Operating the DNL910 and DNL920

This section explains how to operate the DNL910 and DNL920 loggers and provides an overview of the menu options on the units’ LCD screen.

3.12.1. 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:

Fourier Systems Logger

on the keypad.

3.12.2. 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.

3.12.3. 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:

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

Scan for network Found # network

Once the scan has been completed the following screen appears:

Scan complete

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.

Network 1:

Network 1: ID: 014.061.082

ID: 014.061.082

Once the network has been selected the following screen will be displayed.

Joined network: ID: 021.207.175

To rescan the networks, simply select the Rescan Networks option and the logger will start the scanning process again.

If only one network was found the system will automatically connect to that network without the user needing to select the network manually.

There are two possible device modes:

• DataNet Logger

Device is operating as standard data logger

• 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 3.12.3 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 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.

Turning the Unit Off

1. Press and hold the logger button until the LED emits a fixed, red light.

2. Release the logger button. The LED will then blink red three times and switch off.

Turning the Unit On and Joining a Network

The action of turning on a unit means that it will also have to join a network.

3. Give the logger button a short press.

4. The logger will search for a network. The LED will blink orange until either of the following two scenarios occurs:

 The logger cannot find a network and the LED will

blink red three times. The logger will shutdown.

Note: The logger won’t find a network if its SN wasn’t entered in the Device Filter, if the Receiver isn’t online or if the network is locked (go to the Network menu to unlock).

 The logger finds a network and the LED blinks green

three times. It has now joined a network.

5. Once the logger has joined the network you may configure it to start recording data. Refer to section 4.12.

Rescanning for New Networks

To have the logger rescan for a new network (the logger is moving from network to another), from Off status, hold the logger button down until the LED emits a constant orange light. This indicates the logger is rescanning available networks. It will then connect to the network which recognizes its Serial Number, as it was entered in the Device Filter.

Note: If there are multiple DataNet networks in your environment make sure that the logger SN is listed in the Device Filter of only one of these networks, otherwise you can’t control which network it will join first and you will have to rescan the networks several times.

3.13.2. Leave Network and Reconnect to a New Network

To leave the current network, take the following steps.

1. Turn off the unit by holding the logger button down (see

section 3.13.1 above).

2. Once shutdown, hold the logger button continuously. The LED will blink green three times, indicating that the unit has joined the old network. Continue to hold the button until the LED turns orange, indicating it has left this network. Release the button. The logger will start scanning for a new network.

3. One of the following scenarios will occur:

 If the unit finds a new network, the LED will blink

green three times and the logger will have joined the new network.

 If no new network is found, the LED will blink red three

times and the logger will shut down.

3.13.3. Running Logger Signal Test

You may run a signal test on the logger to check the signal strength to the parent unit.

Running Signal Test from Logger

1. Ensure the logger is on and connected to a network.

2. Give the logger button a short press.

3. The LED turns green and after up to 10 seconds starts to blink. The frequency of the blinking indicates signal strength.

 Very good transmission level: LED blinks at a high

frequency means 75% or higher transmission level.

 Good transmission level: LED blinks at a medium

frequency meaning 50% - 69% transmission level.

 Low transmission level: LED blinks at a slow

frequency meaning 25% - 49% transmission level.

 If in current location there is no connection to the

nearest Repeater or Receiver the LED will continuously blink red.

4. At the start of the signal test the Logger icon on the Map View blinks.

5. To stop the signal test, give the logger button a short press. After one minute the test will cease in any case. When the test ends, the LED emits a few short red blinks quickly followed by several green blinks.

Running Signal Test from DataNet Software

Right-click the logger icon on the Map View and select the Signal Test option. The signal test will proceed on the logger as described in Step 3 above.

Note: Performing transmission level test consumes a lot of battery power; do not repeat this test too many times.

3.13.4. Call Unit from Software

To locate the logger via the software, right-click the logger icon on the Map View and select the Call Device (LED) option. The logger LED will alternate between slow green and red blinks and after several blinks it will stop.

3.14. Operating the DNR800 Mini Repeater

This section explains how to operate the Mini Repeater using the multi-functional button on the logger front panel. There is no LCD screen on the Mini Repeater.

Ensure the device Serial Number has been added to the Device Filter before continuing. Refer to section 2.5.3.

3.14.1. Turning the Unit Off and On

The Mini Repeater is powered by external AC power supply only. There is no battery backup. When the AC adapter is connected, the unit is switched on and will automatically search for a network. When disconnected the unit is shutdown and is disconnected from the network.

Turning the Unit On and Joining a Network

The action of turning on a unit means that it will also have to join a network.

1. Connect the unit to AC power.

2. The device will search for a network. The LED will blink orange until either of the following two scenarios occurs:

 The device cannot find a network and the LED will

blink red three times. The device will shutdown.

Note: The Mini Repeater won’t find a network if its SN wasn’t entered in the Device Filter, if the Receiver isn’t online or if the network is locked (go to the Network menu to unlock).

 The device finds a network and the LED blinks green

three times. It has now joined a network.

3. Once the device has joined the network you may configure the Repeater name.

3.15. Operating the DNR900 in Receiver Mode

This section explains how to operate the Receiver using the menu options on the units’ LCD screen, as how to change the DNR900 unit type from Receiver to Repeater.
