ZONESCAN 800/820 Correlating Radio Logger 1. Introduction Welcome to the ZONESCAN 800 System. ZONESCAN 800 is a professional, easy‐to‐use analysis and documentation tool for detecting leaks in drinking water distributions. It consists of small, intelligent units (loggers) that are deployed throughout the distribution network for collecting analysis data and a communication unit for interactive controlling and transferring the data to a mobile computer (laptop).
1.1. System Components The ZONESCAN 800 system consists of the following components: ‐ Radio loggers ‐ System Communication Link (ZS820 Bluetooth) ‐ Communication cable (Serial/RS 232C) ‐ Mobile computer (laptop) with ZONESCAN 800 software 1.2. Radio loggers The radio loggers continuously monitor and analyze noise characteristics. The loggers need no maintenance.
2.1. 2.2. Initial ZS800 Commlink Setup Identify the Commlink, does it require a cable or Bluetooth to connect to a computer. If it’s a cable continue with this section. If it’s a Bluetooth go to Section 2.3. The pathway of communication between the Commlink, Zonescan software and the computer’s communication ports require configuration before the loggers can be used. [Fig.1 Connect the System Communication Link via the Communication Cable to an unused COM port of the PC.
After these basic setup steps the software is prepared for normal operation. It is recommended to check radio connection to the loggers next: 2.2. Check Radio Connection Refer to section 3.1 on how to insert a logger to use to check the Radio Connection. Select a logger in transmission range (click on according entry in logger list) and press the function button Logger State or the function key F3.
1 Zonescan Loggers Process Flow Chart START Create new database To program the logger, synchronise PC and all required loggers using the COMM LINK via RS232 connection or Blue Tooth More logging required? Yes Retrieve deployed loggers and down load data No Analyse the leak noise results Run correlations for each logger Do results indicate a leak? Red = probable leak Amber = possible leak Green = No leak YES Pinpoint with AQUASCOPE 3 No END 9
3. Creating a new Database Start the Zonescan software in standard professional mode, see page 63. The Zonescan Loggers are individually identified by a serial number which is stamped on the top of the logger. This serial number is used by the Zonescan software as a means of communicating with each logger. Fig.3 shows how to create a New Project by selecting File from the menu bar and then selecting New Project from the pull‐ down menu. Fig.
3.1 Inserting a New Logger The main window is blank, its ready to insert the loggers required for the newly created project. Select the Insert New Logger as in Fig.5, a new smaller window will appear to allow the logger serial numbers to be entered. Click OK and then to enter another logger, repeat the process. The Logger Position and comment maybe filled in after the Loggers have been deployed however it is important that the logger position is noted on a Map when deployed.
3.3 Logger Setup – Measurement Settings The Start and Stop time’s aswell as the Interval (sample rate) require setting to suit your requirements, the best time period is when pressure is highest and consumption is lowest, if this doesn’t happen then the standard settings will remain as in Fig.6. Click the Logger Setup Icon.
3.4 Zonescan 820 Sensitivity Boost The Zonescan 820 Loggers have an extra feature which Boost the sensitivity of the sensor, this is recommended for very quiet leaks. Tick the box as in Fig.8 and copy to all loggers to set the Boost. Fig.
4 Programming the Loggers Connect the Commlink with Antenna to the PC and switched on. Click the Synchronize button and a smaller window appears. See Fig.9. Tick the option Transfer logger settings from PC to Logger, this means the settings selected in Logger Setup and the PC time will be transferred to the Logger. The Zonescan Loggers are versatile with respect to the Order of Synchronization.
Fig.10 get measurements synchronization settings 4.1 Programming‐ Correlation To take advantage of the correlation function of the Zonescan Loggers the option must be selected by ticking ‘Prepare logger for correlation (record sound signal)’. Choose a Recording time which is between the measurement times of 1:00am to 4:00am, 3:00am is recommended. Leave Noise Reduction selected as this record 3 separate 8 second recordings. Choose a 5 to 10 minute Rec.
of the main database window, when all loggers are synchronized the progress window will be blank and the read column for all loggers will be green. Fig.12 synchronization process 4.2 When a logger(s) fails to synchronize If a logger fails to Synchronize then individually synchronize the logger by using the ‘Logger State’ (eye symbol) function. Click the Synchronize button within the ‘Logger State’ window.
5 Deploying the Zonescan Loggers Print out a paper copy of the deployment area map, as you move around the area mark the position of the Zonescan Logger’s Serial number on a printed version of the Digital map. Use the Spacing Guide to help set the loggers out. It’s important not to over space the loggers, use the table in Fig.15 as a guide. Fig.14 hard copy of a digital deployment map Pipe Material Pressure Ductile or Cast Iron Ductile or Cast Iron A.C A.
5.1 Deploying the Loggers in the field Use the following photographs as a guide to quality logger deployment. 1. Open the chamber Lid 2. Clean the Hydrant or Valve with a wire brush 3. Make sure there is a good, clean, magnetic contact to the valve stem or hydrant. For optimum sound and radio transmission deploy the Zonescan vertically. To prevent the Antenna touching the metal lid and reducing transmission, fit a polystyrene block between the lid and Antenna.
4. 6 Importing a Digital Map into the Zonescan Software Step 1. To setup and view a map from the PC hard drive, select; “Show Map” (the Globe icon) on the menu bar. Step 2. A map window will open as shown in Fig.16. Next, click “Picture Manager” (the Map icon) in the Map window menu bar Fig.16 mapping window Important: Save Digital Maps in a known folder in JPEG or BMP format, to convert a different file format by print screen the image and open in paint then save it as a JPEG or BMP.
Step 3. Click the first File box twice to open the “Select Picture File” window. Locate and ‘double click’ on desired picture file then close Picture Manager Window. See Fig.16.1 Fig16.
Step 4. Zoom in by selecting the desired scale from the pull down menu or alternatively, zoom in or out one scale at a time by ‘right clicking’ the mouse and selecting “Zoom in” or “Zoom out” Fig16.
Step 5.To move loggers to desired position on the map, select the “Move loggers” icon on the menu bar then, using the PC mouse, click and drag each logger to its desired position on the map The logger being moved will also be highlighted on the logger database Fig.16.
To view the main window (the project database) over the map at any time, click on the “Show Main Window” icon on the menu bar and reduce the main window to the desired size. Arrange screen layout of Map and Database windows as desired using the standard Windows “Maximise” and “Restore Window” icons Fig.16.
7 Downloading the data in the Loggers Ensure the CommLink, antenna and PC connections are correctly made and switch the Commlink on. Click the Synchronize button and a smaller window appears. See Fig.17. To download the loggers, begin by selecting the box; ‘Get measurements’. If ‘Transfer logger settings from PC to logger’ is selected then this will prepare the loggers for the next logging session, be sure to select the Logger settings prior to Synchronization.
7.1 Setting the Threshold Leak Levels To set alarm threshold warning levels for leakage & low battery, select the “Set‐Up” icon on the main database menu bar. Enter desired Possible and Probable Leak threshold value(s) see table Fig.19 for correct values to suit the pressure and pipe material. Fig.18 logger options Pipe Material Ductile or Cast Iron(High Pressure Greater than25m) Ductile or Cast Iron (Low pressure lower than 25m) A.C (High Pressure Greater than 25m) A.
7.2 Start the Download Now all the Threshold and Synchronization settings are entered click start. The following screen shots explain what happens during the download process. Fig.20 downloading started As each logger is synchronised, a leakage probability is calculated.
A correlation recording may take slightly longer to transfer, as the file is larger than logged data. Real‐time progress of the file transfer is given. Fig.22 download complete As each logger is synchronised, if the leak value falls BETWEEN the user selected thresholds, “POSSIBLE LEAK INDICATED” will be audibly announced, and the respective logger will be turn ORANGE in the database and also on the map view.
8 The Noise Logging Principal An understanding on how the Zonescan Loggers build the Histogram will help when interpreting the results. The following section explains how the sampling process works. The tables depict when the logger takes a noise sample and what the sample is caused by, e.g a passing car or leak. Traffic & Consumption noise should be ignored. A large number of samples at the quietest level, indicate a consistant sound that could be a leak which never stops.

9 Analysing Results To view the amplitude distribution graph of the logged results: Step #1 : select the desired logger in the database window Step #2: select ‘Show measurements’ on the menu bar (shown as a bar graph icon) or alternatively double click the desired logger to show the measurement histogram. Highlight the desired date to view historical recorded data for the selected logger Fig.
9.1 No Leak Result The following screen shots show a No Leak situation. Fig.24 no leak measurement with logger list and map Fig.
9.2 Possible Leak Result The following screen shot show a Possible Leak situation: Fig.
9.3 Probable Leak Result The following screen shots show a Probable Leak: Fig.
9.4 Interpreting noise logging results Steps 1 – Analyse all logger s Histograms to establish the “no‐leak” noise level in the area. Fig.28 3.5 dB minimum noise histogram Fig.29 5db minimum noise histogram 3.
Step 2 – identify areas 2 to 3 db higher than the “no‐leak” level Fig.30 7dB minimum noise level 7dB Minimum Noise Level Step 3 – Determine the Areas of Interest Analyse the minimum noise level for each logged point. Higher minimum noise levels are closer to the leak. Fig.
9.5 Which logger is closer to the leak? It’s only natural to use the Leak Value as an indication which logger is closest to the Leak however closer analysis of the Minimum Noise Levels is required, see the following examples. Fig.32 quieter possible leak 7dB Minimum Noise Level Fig.33 possible leak 9dB Minimum Noise Level Although Fig.32 has a higher Leak value than Fig.33 the later is closer to the leak with a higher minimum noise level.
9.6 What is the Leak Value? A calculated percentage of there being a leak based on the noise level and number of samples (consistency). Fig.33 what is the leak value High levels and narrow peaks create high leak values. Any leak value above 0 could be a leak especially in a quiet pipe network environment such as low pressure PVC. 9.7 Reliability of Results The noise logged results indicate any constant noise for the logging period.
10 Performing Correlations Correlation is the process of pinpointing the position of a leak between two loggers. In order to run correlations ‘Sound Recordings’ must be selected in the Synchronization menu and then downloaded once the logging is complete. 10.1 Correlation between two loggers Click the single pipe symbol with a leak to reveal the Correlation window. Fig.35 opening the correlation window Step #1: Select the first logger in the database indicating leak or possible leak.
Step #4: Enter distance measured along pipeline between the two loggers Step #5: Select the pipeline material from the pull-down menu Step #6: Select the pipeline diameter from the pull-down menu Sound velocity and filters are then computed automatically Repeat process for up to 4 different pipe sections between the two loggers Fig.36 entering the pipe details Fig.37 adjusting the filters In the Correlation window the low and high filters maybe adjusted to clean up and fine tune the correlation graph.
10.2 The Correlation Result Fig.38 correlation window When Examining the Correlation Graph a clear peak as shown in Fig.38 is required for confidence leak detection. Q = Quality of correlation so the more bars the better. The Position of the Leak is shown in the Result window with the distance from the Leak to either Logger is given. If incorrect distances are entered then the result will be wrong.
10.3 Exhaustive Correlation Click on the Execute all correlations button to perform an exhaustive correlation. The window appears enabling the user to change the quality limit and distance between 2 loggers before execute correlations. Fig.39 setting the preferences in execute correlations Press start to correlate and all the combinations will be explored. A list of correlation greater than quality limit (e.g. 60%) will be produced.
11 Interpreting the Correlation Results Leak Positions in the Central Third are more accurate but beware of centre correlations. Small velocity errors will cause correlations in the outer thirds to be less accurate. Never dig a hole based on a correlation peak, unless you have confirmed the leak position with a ground microphone. Fig.40 middle third of correlation screen Fig.
Fig.42 the following screen shot shows an example of an out of bracket correlation: the main peak on the graph is beyond the 0mand is confirmed by the ‐4.5mresult. Choose the next logger beyond the logger1 (108518) to bring the peak within bracket as shown below in Fig.43. Fig.
Fig.44 this shows a centre correlation created by both Loggers 1 and Logger 2 being the same logger 108097. To avoid centre correlation Logger 1 and 2 must be different serial numbers.
12 Project Management The software provides a project management in order to allow the user to manage different projects. A project may be a local distribution network or part of it (e.g. a town, a suburb, etc.) or any other organization unit. All loggers that are to be inserted into the software's database must be assigned to a project. Loggers may be inserted into several units with the same logger number.
13 Appendix Section 13.1 Wizard Assisted Version How To Start: After first time starting of the software: 1. 2. 3. Please select I want to create a new project Choose a name for the new project and enter the name of the project Insert loggers: Enter logger no. of first logger (as imprinted on logger case) and add a short description of logger position and press OK. If you like to add additional loggers please answer question with Yes 4.
‐ Print report: Printout of the tabular logger list ‐ Show measurements: Displays measurement window to view measurement results including leak value and amplitude distribution (see View Logger Measurements) . ‐ Correlate sound signals: Displays a window that allows Correlating of sound signals in case appropriate sound signals have been recorded. ‐ Navigation buttons: These buttons provide easy navigation functions for selecting a logger.
13.2 Main Menu (Wizard Assisted Version) 13.2.1 F i l e New project...: Create a new empty project (see Project Management) Open project...: Open an existing project Save project as...: Save current project under a new project name Delete project...: Delete current project including all loggers Send project...: Pack current project into a ZIP file and send it via e‐mail or save it on disk Import project...: Import project from a project ZIP file Print...
13.3 Logger State (Wizard Assisted Version) The Logger State window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F3. It allows checking of the logger's settings, battery state and availability of measurements. Additionally, there's a remote listening function that allows the user to "listen" to the logger's input signal. After opening the window the software first tries to establish a connection to the Comm Link.
13.3.1 S y n c h r o n i z e This button can be used to initiate the synchronizing process only for the selected logger instead of synchronizing all loggers. "Synchronizing" is the process of sending logger setup data and receiving measurement data, for details see Logger Synchronization. After synchronizing the logger can't be re‐ synchronized for about 1 min. (during synchronization of all loggers: 5 min.). The button is enabled after successful connection to logger. 13.3.
13.5 Logger Synchronization (all loggers) – Wizard Assisted Version Logger synchronization is initiated/terminated by selecting the appropriate menu item or function button in the main window or by simply pressing F2. Logger synchronization allows programming of the loggers by transferring the corresponding logger setup data to the logger and receiving stored measurements from the loggers. In wizard mode the user will be guided through the synchronization setup.
If the synchronization process includes programming or receiving of sound recordings, it is very important that the synchronization process won't be interrupted until all loggers will be synchronized. Synchronization process is interrupted by pressing the Synchronize button again, by disconnecting the Comm Link, by exiting the program or switching off the PC. Interruption of the synchronization process will cause a switch off of the Comm Link, thus losing clock synchronization.
Buttons: The printer symbol button corresponds to the menu item Print report. The navigation buttons allow switching to another logger without leaving the Measurement window. 14.1 Correlate Sound Signals (Wizard Assisted Version) The Correlation window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F7. It allows correlating of the sound signals of two loggers in order to calculate leak positions. How to correlate: 1.
3. Enter pipe data For calculating cross correlations, pipe data has to be entered by selecting the menu item Measurement ‐ Enter pipe data... or pressing the button Up to 4 different pipe sections may be entered by selecting pipe section length, material, diameter and sound velocity. If material or diameter is not in the list or exact sound velocity is known, sound velocity can be entered manually by selecting material Other. Entered pipe data will be automatically stored in internal database.
exceeding the limit value will be listed in the result list (correlation quality, peak maximum value, distance to the middle, logger numbers, date and time of sound recording). Results may be sorted by column (mouse click on column header). They also may be exported or printed. Execution of this function may take up some considerable amount of time, depending on the number of loggers in the main window's list.
Standard Professional Version This is the initial screen. You have 3 seconds to change the Options otherwise the software continues in the previously used mode. On first use of the Zonescan software standard wizard assist mode starts. How To Start After first time starting of the software: 1. Create new project: select menu command File ‐ New Project..., and then enter project name and press OK. 2. Insert loggers: Press function button Insert logger , then enter logger no.
4. 5. Check COM port setting: select menu command File ‐ Options ‐ Setup, then select Connection and modify setting if necessary 5.. After these basic setup steps the software is prepared for normal operation. It is recommended to check radio connection to the loggers next: Select a logger in transmission range (click on according entry in logger list) and press the function button Logger State or the function key F3 .
After deploying the loggers in the distribution network, programming of the loggers and receiving of measurement data is done by means of the Synchronize function. Main Window (Standard Professional Version) After starting the software the main window is displayed on the screen. The window is subdivided into a menu bar, a control panel with Explorer‐style function buttons, a tabular list of the loggers of the actual project and a status panel at the bottom of the window.
21 Function buttons The function buttons are arranged on sub‐panels that can be easily rearranged and even be detached from the main window by grabbing the left side with the two vertical lines and dragging them to the desired new position. A short description of the function of each button is displayed by moving the mouse cursor over the button (without pressing the button) and waiting a short time.
‐ Navigation buttons: These buttons provide easy navigation functions for selecting a logger. Alternatively, logger may be selected by clicking on an entry of the tabular list or by using the arrow keys of the keyboard (only possible when list has the focus, i.e. list is the active element in the window).
Amplitude Distribution Histogram Result Expanded Step 1 – establish the “no‐leak” noise level in the area. Minimum noise is 4db Step 2 – identify areas 2 or 3 db higher than the “no‐leak” level. Minimum noise is 7db Step 3 – Determine the Areas of Interest. Analyse the minimum noise level for each logged point. Higher minimum noise levels are closer to the leak Use these 3 steps to help determine which logger(s) the leaks is near to, this is especially useful in quiet PVC environments.
23 Status panel The left section of the status panel indicates whether there's a connection to the System Communications Link or not. Connection is needed during synchronization and when checking the logger state. The middle section displays battery voltage and firmware version of the System Communication Link during connection. The right section is used for status messages, especially during synchronization. Main Menu (Standard Professional Version) 24 File New project...

Logger State (Standard Professional Version The Logger State window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F3. It allows checking of the logger's settings, battery state and availability of measurements. Additionally, there's a remote listening function that allows the user to "listen" to the logger's input signal. After opening the window the software first attempts to establish a connection to the Comm Link.
Battery voltage: Battery voltage of the logger. Note: The voltage value of a fully loaded logger battery typically remains at 3.0 V steadily for a long time, as the value can't exceed 3 V due to internal restrictions. Temperature: Temperature inside the logger's case Start measurement: Programmed starting time of daily measurement (see Logger Setup) Stop measurement: Programmed stop time of daily measurement Interval: Programmed measurement interval Version no.: Logger firmware version no.
Logger Setup (Standard Professional Version) The Logger Setup window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F4. It allows adjustment of the properties of the actual selected logger: Logger no.: Each logger has its own unique logger number that is needed for identification. This number can be found on the logger case. The number has to be entered exactly into the Logger no.
they are confirmed or cancelled by the user. Confirmation is done by pressing the ok symbol button or the Return key or by switching to another logger, cancellation is done by pressing the X symbol button or the Escape key. In case the Logger Setup window is invoked by the Insert logger function, there's also an Insert multiple loggers button. This function allows easy insertion of a sequence of loggers with consecutive logger numbers.
Logger Synchronization (all loggers) ‐ Standard Professional Version Logger synchronization is initiated/terminated by selecting the appropriate menu item or function button in the main window or by simply pressing F2. Logger synchronization allows programming of the loggers by transferring the corresponding logger setup data to the logger and receiving stored measurements from the loggers. After initiating synchronization a window is displayed, allowing the user to select synchronization options.
Leak values and all available amplitude distributions: Full synchronization, may take longer time than Fast Sync mode, depending on number of stored amplitude distributions. 33 Correlation Press the More Button to access the Correlation options Prepare logger for correlation (record sound signal): Program logger for recording of sound signal at the desired recording time. The recording of sound signals allows correlation in order to locate the noise source (especially leaks).
Important Notes (please read): Please check whether Order of Synchronization option is adapted to the transmission situation. Synchronize only reachable loggers won't work properly with too many loggers and Synchronize according to logger list won't work properly with deployed loggers. In case synchronization of a single logger is desired please use the Synchronize command from the Logger State window.
View Logger Measurements (Standard Professional Version) The Measurements window allows viewing of the stored leak values, amplitude distributions and sound measurements. It is displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F5 (leak measurements and amplitude distributions) or F6 (sound signals). It allows graphical and tabular representation of the stored data, plus printing and exporting of the data.
37 Measurement data Measurement data can be shown in graphic or tabular view. Switching is done by the corresponding menu command or function button. When showing leak measurements, the displayed measurement data is the amplitude distribution of the signal monitored and analyzed during the programmed measurement period (see Logger Setup). Analyzing the amplitude distribution allows obtaining further information concerning measurement conditions, interfering noise sources, etc.
Menu commands: 39 Measurement Print report...: Print overview list or graphic view of the displayed measurement data Find measurement...: Find measurement by date Allow multiple selection: Enable multiple measurement selection for deletion Delete measurements: Delete currently selected measurement(s) Delete all measurements: Delete all measurements of currently selected logger 40 View Graphic/tabular view...
Chart Options (Standard Professional Version) The display features of the graphic view (chart) may be changed by the user: Function buttons From left to right: Type of presentation: Area chart, bar chart, line chart, point chart Chart options: Activate/deactivate vertical grid, horizontal grid, 3‐D‐view Colours: Colour of the background, of the grid and of the foreground (measurement graph). Unzoom functions: Adjust chart to all values (un‐zoom in y direction), show all values (un‐zoom in x direction).
41 Correlate Sound Signals (Standard Professional Version) The Correlation window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F7. It allows correlating of the sound signals of two loggers in order to calculate leak positions. How to correlate: 1. Select loggers Enter logger No. or use navigation buttons to select logger 1 and logger 2: When selecting the same logger No.
43 Status panel When selecting loggers and sound recordings the status panel shows whether correlation is possible or not and gives further information. 3. Enter pipe data For calculating cross correlations, pipe data has to be entered by selecting the menu item Measurement ‐ Enter pipe data... or pressing the button Up to 4 different pipe sections may be entered by selecting pipe section length, material, diameter and sound velocity.
Test correlation Function for a quick check whether the selected combination of loggers produces a reasonable correlation (i.e. probable leak) or not. Pipe data does not need to be entered (the correlation will be calculated on base of a pipe length of 600 m and a sound velocity of 1000 m/s). Correlation quality will be calculated and will allow quick assessment whether a leak is probable. Note: This function is not suitable to obtain leak distances.
Logger Map (Standard Professional Version) The Logger Map window may be displayed by selecting the appropriate menu item or function button in the main window or by simply pressing F8. It is used to show a geographical view of the project's loggers. The loggers are displayed as symbols together with their logger number on a geographical map.
44 Function buttons: Show main window: Switch to main window. Show grid: Toggle display of a coordinates grid. Move loggers: When pressed, loggers may be moved by mouse: After selecting a logger symbol, it may be dragged to a new position with the left mouse button. Picture manager: Shows a window that allows managing of the background pictures (maps). One or more picture files may be inserted to the pictures list.
Status panel: The left section indicates the mouse cursor position transformed to geographical coordinates. The right section shows the logger number of the selected logger, together with the leak value of the newest measurement (if available). Map origin coordinates and extensions may be changed in the Logger Setup window. Deployment of Loggers: when deploying the loggers around the network the logger spacing is critical especially if correlation recordings are made.
Program Setup (Standard Professional Version) The Program Setup window may be displayed by selecting the appropriate menu item (Options ‐ Setup) or function button in the main window. It allows adjustment of general settings of the program: 45 Warning levels Selection of warning levels for leak value and logger battery voltage.
46 Map Selection of origin coordinates and extension of the Logger Map. 47 Connection Selection of COM port. 48 Audio Create/change recordings of audio messages during synchronization process. The respective message can be selected by choosing a list entry. The recordings may be played (if available) or re‐recorded. For new recording of a message the option Allow recordings must be enabled. Recording and playback volume settings may be changed by pressing the corresponding buttons.
Data Synchronization via Palm HotSync® The ZONESCAN 800 software package includes a software module for transferring measurement and logger setup data between a PC (laptop) and a Palm OS® driven handheld via the Palm HotSync Manager® . This software module is called a conduit.
53 Handheld overwrites PC Logger and measurement data will be mirrored from handheld to PC. Existing data in the PC database will not be deleted (but may be overwritten). In case the handheld project name does not exist inside the PC database, the project name will be automatically added as new project to the PC database. This mode is especially useful for transferring handheld data to several PCs. Do Nothing (No Action) No data transfer will occur. Change of synchronization mode may be done temporarily (e.
55 Zonescan820 Commlink Setup The Zonescan820 Commlink (shown below) uses Bluetooth to connect with a computer. The Computer either requires an inbuilt Bluetooth or a USB Bluetooth dongle for communication with the Commlink. The Bluetooth Hardware usually has Bluetooth Managing Software which controls it. Bluetooth Manager Software The Computers with inbuilt Bluetooth are normally activated by pressing a button or flicking a switch.
1. Open the Bluetooth Manager on your PC, turn on the Zonescan 820 Commlink and refresh or search for devices. The Commlink will appear as a device but not as a mobile phone. 2. Create the Bluetooth Link by selecting the Device, double click the symbol and enter the pin code which is 4 zeros (0000) and click OK, see below. 2. 3. The Serial number of the Commlink (this is on a label underneath the unit) will be displayed. 3. 4.
4. 5. Connection to the ZS820 Bluetooth device will happen through a designated com port. In this example it is com5‐ remember this port. 5. 6. For this Bluetooth Utility a link is shown by a dotted line to the Sun. Other Bluetooth Managers will display this in another way. 6.
7. Disconnect from the ZS820 Bluetooth device by choosing the option to Disconnect. 7. 56 Creating the link between the Zonescan Software and Bluetooth Manager 1. Open the latest version of the Zonescan Software, in this example its 5.13. 2. Go to Setup and then choose Options.
3. Select the Commlink’s allocated com port, in this example COM5 in the Connection drop down and click OK. Use Logger State to communicate with a logger to check the setup is correct. Note. The Zonescan820 is rechargeable so charge the unit before use. 57 Updating the Commlink Firmware Make sure a connection is made with the Commlink by communicating with a logger using the Logger State function, then close the Logger State window.
Browse for the saved latest version update file and then select and open . The progression of the update is displayed as a counting up percentage as shown above. Once this reaches 100% then programming begins as shown below. The connection will fail as the Commlink will turn itself off when programming is complete. Switch the Commlink back on and establish a connection. The new version firmware will be displayed next to the battery level.
