User manual of HDServer1 software Introduction
The HDServer1 software allows receiving, entering in a database and viewing the measurements detected by a series of devices (in particular, data logger of the HD35... and HD50... series) connected to the Ehternet or Wi-Fi local network (directly, for the HD50... series, or through the HD35APW base unit, for the HD35... series).
The software consists of two parts that work independently:
• The Server part, which receives and enters in the database the data coming from the devices.
• The Viewer part, which displays the data in the database on the PC monitor.
The software can be installed in multiple PCs. The Server part is normally active in only one PC, while the Viewer part can be active simultaneously in several PCs.
WARNING: Correct operation of the database requires the installation of MySQL database management system. The database management system can be installed in any PC of the local network (even in a PC where the HDServer1 software is not installed). In order to install MySQL, run the file Autorun.exe of the software package, select Install MySQL and follow the instructions in Guide to MySQL server installation available in Documentation section.
After installing the HDServer1 software, start it by double clicking on the program icon on the desktop or by selecting HDServer1 from DeltaOhm folder in the Start menu. Two windows open: the Server window and the Viewer window.
The Server function receives and enters in the database the data coming from the devices. To activate the Server function it is sufficient, in the Server window of the software:
1) To set the IP address and the credentials for the connection to the database (MySQL setup panel).
2) To set the IP address and listening port of the PC acting as Server (Listen setup panel).
3) To set in the Client devices (HD50... data loggers or HD35APW base units) of the network the IP address and port number of the server set in the previous point. See the Search Devices function to set the IP address and port number of the server in the Client devices.
4) To press the Start Server button (at the bottom of the window). The Client devices of the network will be automatically detected by the program.
Set the following parameters to connect to the database:
Hostname / IP : insert localhost (or 127.0.0.1) if the database is installed in the same PC as the software; on the contrary insert the IP address of PC where the database is installed.
Port : enter the port number inserted during MySQL installation.
User : leave default setting (root).
Password : enter the password defined during MySQL installation.
Press Save to save the settings.
Press Connect to connect to the database. The correct connection is indicated by a green box at the bottom of the window (if the connection fails, the box is red).
Set the following parameters:
Listen on : select, from the drop-down list of available addresses, the IP address of the PC in which you are activating the Server function.
Listen on Port : enter the port number on which the Server listens for connection requests from the Client devices of the network.
Press Save to save the settings.
WARNING: The IP address and port number entered in this panel must also be configured in the Client devices (HD50... data loggers or HD35APW base units) of the network using the "Search Devices function" described below.
By pressing the Search Devices button (at the bottom of the Server window), it is possible to search for the devices connected to the network and configure in the devices the IP address and port number of the server to which data are to be sent.
To search for the devices connected to the network, select the "Scanner" panel, set the IP addresses scanning range and press the START SCAN button. At the end of the search, the list of the devices found will appear.
The "IP server" column indicates the IP address of the server set in the device and to which the device sends the data. The "Status" column indicates whether the device is enabled to send data to the server or not (1=yes, 0=no).
In order to set in one or more devices the
server IP address defined previously in the "Listen setup" panel,
select the devices (the 
icon
allows selecting all and only the devices having a server IP address different
from the one to be set) and press the CONNECT button.
It is also possible to set in the devices a server IP address different from the one set in the "Listen setup" panel. In this case, select the "Options" panel and set the "IP Server Address" fields (the default values are those defined in the "Listen setup" panel). If necessary, change the server "Timeout" (time within which a device must send a reply to the server).
From the "Options" panel go back
to the "Scanner" panel, select the devices (the
icon can be used to select all and only the devices having a server IP address
different from the one to be set) and press the CONNECT button.
In order to stop sending data from a device to the server, select the device and press the DISCONNECT button (the value in the "Status" column becomes 0).
Note: the "Interface" panel only reports information on the PC network card.
Opening a device web server:
By right-clicking on a device in the list of the devices found, the device web server can be opened (only for devices equipped with web server).
"Connected Clients" and "Info devices" panels
The "Connected Clients" and "Info devices" panels are only viewing panels (no configuration is required).
The "Connected Clients" panel lists the devices currently connected, with the corresponding serial number.
The "Info devices" panel shows information on the devices detected by the software: IP address, model, serial number, etc.
Note: in the "Info devices" panel there is also a "Drop aggr. Table" button for each device, which allows deleting some tables created and used by the software to draw the graphs. Use the button only in case of extreme necessity.
The "Text Out" and "Text In" boxes display the communication in progress between the Server and the Client devices.
Stopping the Server function
After starting the Server function, the "Start Server" button becomes "Stop Server". If you want to stop the Server function, press the Stop Server button.
WARNING: If the "Required password" option of the software has been enabled (see the section Software options), the password will be requested to change the software settings. The password is supplied with the data loggers.
The Viewer function displays the data in the database on the PC monitor. In the Viewer window, the following areas can be identified:
1. List of saved "Visualizations" ("Visualization" means the set of selected quantities and the appearance with which they are represented, in particular the size and position of the measurement panels). The list can be hidden/displayed by selecting the small icon in the upper right corner of the panel.
2. Toolbar.
3. Measurement panels of the "Visualization" selected in the list of "Visualizations" (point 1).

Creating and saving a "Visualization"
The program allows selecting the quantities to be displayed and saving the current appearance of the Viewer window, in order to be able to recall it later.
1) In the list of devices, select the device of interest: the quantities measured by the selected device appear in the list of quantities. At the top of the list there are two commands that allow you to select and deselect all the items in the list.
2) In the list of the quantities, select the quantities to be displayed.
3) Repeat steps 1 and 2 for all the device of which the quantities are to be displayed.
4) Select Save As... in the toolbar and enter a name for the "Visualization" to be saved, then press Save.
The new "Visualization" will appear in the list of saved "Visualizations". To recall it in the future, just double-click on the "Visualization" name (alternatively, select the "Visualization", press the mouse right button and select Open).
The measurement panels of the "Visualization" created can be resized and dragged to the desired position. The panel highlighted by the green header, corresponding to the device selected in the list of devices, can also be moved by using the arrow keys on the keyboard. In order to resize and move accurately a panel, place the mouse pointer over the panel, press the right mouse button and select Layout setup: the window to set the panel size and position appears.
Press Apply to save the new settings. Press Exit to exit without saving.
In order to save the current appearance of the panels, always use the Save As... command.
To delete a "Visualization", select it, press the mouse right button, select Delete and answer affirmatively to the message asking to confirm the deletion.
In the numerical measurement panels, the following alarm indications may appear:
LOW: the measurement exceeds the lower alarm threshold.
HIGH: the measurement exceeds the upper alarm threshold.
UNDER: the measurement is lower than the minimum measurable (Under-range).
OVER: the measurement is greater than the maximum measurable (Over-range).
ERROR: the measurement is in error.
Displaying the data graphically
To display the data of the "Visualizations" created graphically, select Graphs in the toolbar, then select, in the list of devices, the device of which you want to see the data. The graphs of the various quantities of the device appear one after the other.
Note: the data of one device at a time and only of the devices and quantities belonging to the selected "Visualization" are displayed. To add or hide a graph, it is necessary to select or deselect respectively the corresponding quantity and save the "Visualization" by using the Save As... command in the toolbar.
The control panel above the sequence of graphs allows setting the time in the axis of the abscissas, enabling/disabling the automatic scale of the axis of the ordinates and displaying the alarm thresholds and the AVG, MIN and MAX curves.
Displaying the data of a specific time interval
Enter the interval starting date and time in the From fields and the
ending date and time in the To fields, then press the EXEC button.
Displaying the data of predefined intervals
Select in the drop-down list the predefined interval from those available, then
press the SET button. The available options are:
Last HOUR: the data of the current hour (starting from hh:00:00; e.g., if it is 16:24, starting from 16:00) are displayed.
Last DAY: the data of the current day (starting from 00:00:00) are displayed.
Last WEEK: the data of the current week (starting from the first day of the week, which can be Sunday or Monday depending on the PC settings) are displayed.
Last MONTH: the data of the current month (starting from the first day of the month) are displayed.
Last YEAR: the data of the current year (starting from the first of January) are displayed.
Scrolling the graph
To scroll the graph backward or forward, use the PREV and NEXT
buttons respectively. The scroll interval is equal to the selected predefined
interval (HOUR, DAY, WEEK, MONTH or YEAR).
Search for the most recent measurement
By pressing the LAST button, the program searches for the most recent
measurement in the database (considering all the devices, not just the selected
one) and displays, in addition to the easurement found, the data of a period
equal to the selected predefined interval and preceeding the last measurement
(for example, if the selected predefined inerval is "Last DAY", the
data of the previous 24 hours are displayed).
AVG, MIN and MAX curves
The number of points that can be represented in the graph depends on the resolution
of the PC monitor. If the number of measurements to be displayed is greater
than the number of points that can be represented, the software divides the
measurements in many small time intervals and for each interval calculates the
average value of the measurements in the interval, so as to reduce the number
of points. The AVG curve corresponds to the trend of the average values
calculated. The MIN curve (blue color) and the MAX curve (red
color) are respectively the curve obtained from the minimum values and the curve
obtained from the maximum values of the measurements in the intervals in which
the averages were calculated; The MIN and MAX curves allow evaluating the measurement
dispersion for each point of the AVG curve.
If the setting of the AVG, MIN and MAX options is changed, press the EXEC
button to update the graphs.
Alarm thresholds
Selecting the Show Alarm Thresholds option, two horizontal lines corresponding
to the alarm thresholds set in the selected device are shown. If the setting
of the option is changed, press the EXEC button to update the graphs.
Scale of the axis of the ordinates and colors of the graphs
Selecting the Auto Scale option, the minimum and maximum values of the
axis of the ordinates of the graphs are automatically calculated by the program
according to the measurement data. If the option is deselected, the minimum
and maximum values of the axis of the ordinates are those set manually.
To manually set the minimum and maximum values of the axis of the ordinates
of the graphs, select Setup above the list of quantities. In the window
that opens, set the minimum (minY) and the maximum (maxY) of the
scale of the ordinates for each quantity. In order to change the color of the
AVG curve of a quantity, select the color box and then choose a new color. Press
"Save" to save the settings. Press "Exit" to close the window.

Mobile graphs window:
The Lock Dashboard icon allows you to make the panel with the graphs an independent window that can be moved and resized as desired. When the icon looks as a closed padlock, the panel is "locked"; to make the panel an independent window, select the icon (which becomes an open padlock) and double-click on a dashboard name.
When the window is independent, the control panel above the graphs can be hidden/displayed by clicking on the blue header line just above the control panel.
To re-lock the panel with the graphs, select the "Lock Dashboard" icon again (which becomes a closed padlock) and double-click on a dashboard name.
Some parameters of a device can be configured by selecting the device in the list of devices, right clicking the mouse and selecting Instrument setup.
The "End Device settings" window will open. When opened, the window displays the ED configurations section, which allows setting the user code, the group, the logging interval and the measurement interval.
The User code is an alphanumeric code which identifies the device. Maximum length 20 characters. The ASCII characters from 32 (blank) to 126 (~) are accepted.
The Group is a code useful to identify subsets of devices, for example all devices installed in the same room. Maximum length 10 characters.
The logging interval and the measuring interval can be set to 1 s, 2 s, 5 s, 10 s, 15 s, 30 s, 1 m, 2 m, 5 m, 10 m, 15 m, 30 m, 1 h. The value stored is the average of the acquired values (with interval equal to the measuring interval) within the logging interval set. The measuring interval must be lower or equal to the logging interval (if a higher value is set, it is forced to the logging interval value). Only for the HD35... series, the logging interval coincides with the RF transmission interval of the data from the data logger to the base unit.
The Info measures section lists all the quantities measured by the device. For each quantity, resolution and unit of measurement are shown. If the device measures more quantities of the same type (for example two temperatures), a name to distinguish the quantities of the same type can be entered in the "Set measurement name" field.
The Alarm thresholds section allows setting the lower and upper alarm thresholds for each measured quantity. The alarm is generated when the measured value drops below the lower threshold or exceeds the upper threshold.
The Hysteresis settings section allows setting the hysteresis of the alarm thresholds and the alarm delay for each measured quantity.
The width of the hysteresis is a percentage (0 ... 100%) of the difference between the two alarm thresholds. For example, if Hysteresis=2%, Lower threshold=10 °C and Upper threshold=60 °C, the hysteresis is (60-10)x2/100= 1 °C:
The alarm is generated after the time set in the Alarm delay field. The alarm is generated immediately if "no delay" is selected. If the alarm condition ends before the delay time is elapsed, the alarm is not generated.
Note: the timely reporting of an alarm condition depends on the measuring interval: the shorter is the measuring interval, the more timely the reporting of the alarm condition will be.
To apply the new settings (highlighted by a red flag placed on the right of the modified parameters) , press Apply. An icon at the bottom left of the "End Device settings" window indicates whether the settings have been changed successfully or not.
By pressing the Read button, the software reads the the current configuration of the device again.
In order to close the window, press Exit. If any modifications was made, but they were not transferred to the device, a message will appear asking the user if he wants to transfer the modifications before closing the window.
