18. STYLITIS EXPLORER: STARTING UP
Stylitis Explorer is Stylitis-41’s free operating software.
•
Start up with Stylitis Explorer, by creating Site folders and Connections.
-
-
-
Create one unique site folder for each datalogger.
In each site folder, multiple (different types of) connections can be created for the logger. The different
connection types correspond to the communication methods, discussed before.
The connections created are saved as windows files, which are recognized by Stylitis Explorer in a folder
interface, along with the compressed and decompressed data files (see Chapter 20), and setup files, ie
logger settings (see next Chapter) saved in a file.
There is also a user friendly way to manage and view a list of all the created sites and go to a specific site
with a double-click. View statistics, such as last connection and download (manual and automatic).
Refer to the corresponding screen shot in Chapter 22.
•
After achieving a connection, you can communicate with the logger. Besides changing logger and
Sym-o-net modem (if used) settings and download data, you can view some features, and
specifically:
-
-
View the logger’s status: Instant parameters, such as the date and time, the battery voltage, the current
data file being recorded, the recording time remaining in the buffer and in the card, etc.
View an Online plot of the selected channels’ values. All samples are plotted (every second). Appropriate
units appear on the plot.
Refer to the corresponding screen shot in Chapter 22.
Via the virtual keyboard, navigate in the logger’s menus to view the instant channel values and the
status parameters one by one.
•
•
19. STYLITIS EXPLORER: SETUP
Connect to the datalogger, via Stylitis Explorer, via one of the connections you created and modify its
setup, ie settings such as the recording interval (selectable from 1 min to 1 hour) and the logger’s site
name. However, the main settings to be adjusted are the channel settings.
CHANNEL SETTINGS
The settings of all channels can be changed in two ways:
-
Manually. Change settings manually. Manual setup can be done either via a virtual keyboard, by navigating in the
logger’s menus or via the user friendly Easy Setup (see Chapter 22 for screen shot):
-
-
Select mode. For counter channels select Counter, Frequency or Events. For analog ones, select Analog, PT-100 or Vane.
Select type. For counter channels, select TTL, REED, SIN or #40 (SIN with filter). For Analog channels A3, A4, enable/ disable
the gain (which is standard, by request).
Type the Slope and Offset parameters.
Via Stylitis Explorer’s Sensor Library. Via Easy Setup again, instead of changing the settings manually, you can
select a specific measurement and then a specific sensor, related to this measurement. Optionally, also change
the measuring units. All settings are updated automatically.
SYM-O-NET SETTINGS
Sym-o-net is Symmetron’s GPRS modem which can cooperate with Stylitis-41. If you are using it, adjust its
settings via Sym-o-net Programmer, an add-on software to Stylitis Explorer. The settings to be adjusted are:
-
-
Selection of the modem’s operation, defining the type of the remote connection, as discussed in previous
chapters: GSM data mode, GPRS client mode (via Diameson server) or GPRS server mode.
SMS cellphone number (optionally). An alarm SMS is sent if the power supply is found below 11V.
GPRS settings, if GPRS operation is selected. SIM card provider settings: APN, User Name, Password. Diameson
settings: IP address and Device Listening port.
Email settings. Enable or disable encrypted (according to the password) data emails at least once a day. Define
the SMTP mail server, sender, recipient and if the SIM card provider requires authentication, type the email
account’s User Name and Password.
Peripheral Schedule. Define between what hours of the day the datalogger and Sym-o-net’s DEVICE2
and DEVICE3 will be available for remote communication (and the modem will be turned on).
20. STYLITIS EXPLORER: ACQUISITION AND DOWNLOAD
•
After writing the desired setup in the datalogger, enable data acquisition to start recording.
Data is recorded in compressed form, in two ways:
-
In the logger’s internal 512KB memory (buffer). Only the current file is stored in the buffer, ie if you
set Acquisition=OFF, the buffer is cleared and data are lost.
In a removable Compact Flash card (up to 2GB). The data storage is practically unlimited. Multiple
data files can be stored in the card. A new file begins when downloading the current file or disabling
and re-enabling the acquisition.
•
When downloaded, a compressed file is decompressed into a data file, which can be viewed
via a text editor. Compressed and decompressed data files are stored in the logger’s site
folder, as mentioned in Chapter 18.
• Data download can be achieved either manually or automatically via AutoConnect software
(see Chapter 24).
MANUAL DOWNLOAD
a. From the buffer. Download the current file. In the end, you will be asked if you wish to clear
the buffer and begin a new file or not (the same file will continue to grow).
b. From the Compact Flash. There are 3 download options when you are using a Compact Flash:
-
-
Download the most recent file. If Acquisition is ON, this is the current file. In this case, the current file
is firstly closed (the next file begins) and then downloaded.
Download the card’s directory. This way all the card’s files (the last 256 ones) appear with their
number, start date and size. The directory is also saved in a text file in the site folder.
Download a previous file, by typing their number. Again, the last 256 files are available. To download
all previous files, retrieve the card and read it via a card reader.
21. STYLITIS EXPLORER: OFFLINE DATA MANAGEMENT
After downloading the data files in the site folder, you can manage them offline. Stylitis Explorer offers
some useful tools for offline management and presentation:
•
•
•
•
•
•
Plot. View the selected channels’ plot, in up to 3 graph groups. View values at a specific moment
with the channel units.
Refer to the corresponding screen shot in Chapter 23.
Data File Processing. Check the integrity of a folder’s files, ie check for missing or duplicate records
or if the interval is the same for all files.
Statistics. Statistics of the file’s data can appear per hour, per day, per month and per year.
Statistics include be the average values of the data (within the hour, day, month or year), the max,
min or sdv values, or sum of all values. They are presented via a bar graph or a dot plot.
Refer to the corresponding screen shot in Chapter 23.
Data Availability. View the percentage of the available data of a site folder within the years, in
which there are data. For a specific year, view the corresponding percentage within its months.
Refer to the corresponding screen shot in Chapter 23.
Convert data file parameters. Apply new Slope and Offset values in a downloaded file in retrospect
and create a new file.
Export to WindRose/Excel/.CSV/.TAB file. Export a file’s data to an Excel, a comma delimited or a
tab delimited file. Especially for wind data (speed and direction channels), you can export them to
WindRose, the wind analysis software, add-in to the Microsoft Excel, which is manufactured by
CRES and distributed by Symmetron.
For WindRose, refer to the corresponding screen shot in Chapter 23.

24. AUTOCONNECT SOFTWARE
•
•
•
As stated before, data files can be downloaded manually, via Stylitis Explorer, via any connection.
However, data download, along with other actions as well, can be preformed automatically, in a
regular basis, via the additional free software AutoConnect.
The datalogger can perform a different action each weekday:
-
Download Data: The current data file, either from the buffer or from the
Compact Flash. There is an option to clear the buffer in the end or not.
Download Status: Instant parameters, such as the current file,
the recording time remaining, etc.
Download Display. Get the instant channel values.
Update Captum. Captum is a free service to present real-time
and historical data of Symmetron data loggers on the World Wide Web.
Captum Plot
•
•
The selected action of a weekday can be performed once a day at a specific selected time, or infinite
connections can be made that weekday every as many minutes as you wish.
Besides editing the auto connections (like in Stylitis Explorer) via AutoConnect’s interface, you can:
- View a list of all your automatic connections and execute one or more manually.
- Check each connection’s latest status, ie if it succeeded, or failed and why.
- View the date and time of last connection and last successful download for each one.
