1. INTRODUCTION

Stylitis-41 is designed to make the collection of technical measurements easy and safe. As such, it allows you to:

Communicate through the built-in display and keyboard.

Connect various types of industry-standard sensors like

Anemometers, Vanes, Pyranometers, Thermometers, etc.

Program a time interval, over which the instrument will perform mathematical operations, including minimum, maximum, average and standard deviation.

Store the results of operations in the internal buffer or in external removable Compact Flash memory cards.

Use the serial interface to download buffer contents or as a substitute for the built-in display and keyboard.

The above operations are performed simultaneously without affecting the integrity of the acquired data (refer to Figure 1).

USING STYLITIS-41

6

The Stylitis family of data loggers can operate in several different ways, depending on your application (refer to Figure

2):

1. As a stand-alone unit. You can leave the logger unattended for weeks or months, conditioning and recording input signals. Data are compressed and stored in the internal buffer or in removable Compact Flash cards. If the card is not new or if it has not been used only in the specific datalogger, it induces the user to press button [1] to clear the card. Cards can be replaced without interrupting the acquisition process. Using the

STYLITIS -41 USER'S MANUAL

supplied software (Opton 4) one can read the card via a

Compact Flash reader and convert compressed data to

ASCII text files organized in columns for further processing.

2. As a stand-alone unit with on-line data transfer.

This is done by using the internal buffer as a storage medium. Data are transferred to the PC for further processing via the serial port. Connection between the logger and the PC can be done using a serial cable, a modem (wired or wireless) or a LAN. A COM port, a modem or an Ethernet adapter, respectively, is required on the PC. The supplied Stylitis software is used for the above operations, as well as, the conversion of compressed data to ASCII text files.

3. As an on-line front-end unit. It conditions, samples and transfers signals on-line to a computer for further processing and storage. The user’s program issues a command, which is used to transfer data. Connection between the logger and the PC can be done using a serial cable, a modem (wired or wireless) or a LAN. See 4.

STYLITIS -41 USER'S MANUAL

4. POWER MANAGEMENT

There are three operating modes:

 ENERGY SAVING MODE

This is the default-operating mode. The unit is in standby mode and is awakened once per second to measure, calculate and store results. Since it actually operates only one 100 th

of the time this results in a longer battery life. This operation is invisible to the user since the LCD is off.

Depressing a key for more than one second activates the display, enabling interface with the user. Stylitis-41 automatically reverts to standby mode if there is no key action for 1 minute.

 CONTINUOUS OPERATION MODE

This mode holds the unit continuously activated, thus greatly reducing battery life. It is useful, though, if you want to continuously display an input.

When set for continuous operation, Stylitis-41 does not automatically switch to standby mode. You will have to manually set the operation mode back to 'Energy Save'.

PC SYNC MODE

‘PC SYNC’ enables on-line operation with a computer connected to the serial port. A user software can setup the logger and read measurement data in real-time. For more information refer to application notes AN40-3 and AN40-4.

STYLITIS -41 USER'S MANUAL

13

Connection examples:

See APPENDIX

A.

CAUTION

Do not apply an external voltage to the instrument outputs.

5. MEASUREMENTS

Stylitis-41 is capable of directly measuring voltage, frequency and events.

With suitable sensors it is also capable of measuring:

 Wind speed, direction and wind-turbine power curves.

Interfaces to virtually every type of anemometer and wind vane.

 Temperature, humidity, pressure.

 Solar radiation, rain height, water speed, etc.

Sensors must provide either an analog voltage in the range of

0~5V or a frequency signal in the range of 0~5kHz.

6. OUTPUTS

The vane supply outputs (+5V PULSED) may be used for excitation, as they are capable of supplying up to a TOTAL of

25milliAmps with an accuracy of  0.1%. One of the outputs ( +VA

PULSED ) has selectable output voltage (see APPENDIX E ).

Remember, however, that this supply is pulsed to conserve battery power. It is on for about 3mseconds every 1 second. Thus the average current drawn from the battery (in addition to the one listed in the specifications) is 1/300 th

the total Vane supply current.

Similarly, the anemometer supply outputs (+5V FIXED) can supply up to a TOTAL of 10milliAmps with an accuracy of  5%.

These outputs are not pulsed. Thus, the average current drawn from the battery is the same as the total Anemometer Supply

Current.

14

STYLITIS -41 USER'S MANUAL

To setup vane and analog input parameters:

Select an input,

1-4.

Then use the

[

 ] or [  ] keys to select an option.

CAUTION

Do not apply a voltage exceeding the maximum permissible (  20V) on voltage inputs.

7. INPUTS

 ANALOG INPUTS.

The Analog to Digital Converter used has 4 inputs with a resolution of 12 bits and a range of 0~+5V.

There are 4 options per input:

1. NOT USED.

2. User selectable SLOPE & OFFSET values are applied on acquired data:

Scaled input = (slope x input voltage) + (offset).

Math operations are performed on scaled inputs. These include minimum, maximum, average, standard deviation.

3. VANE input, for wind direction measurements. An input voltage between 0V and 5V corresponds to an angle of

0~360 degrees with a resolution of 1.4 degree.

Math operations include vector minimum, maximum, average, standard deviation. Vane math is NOT the arithmetic average; a vector-averaging algorithm is used to ensure true indication of angle averages.

The user can freely set the zero degree point in degrees

(0~359). This is the actual vane zero in respect to the north. For instance, if the vane “zero” mark is placed 30 east then you enter 30 as offset; if it is placed 30 west you enter 330 (=360-30) as offset.

4. TEMPERATURE PT100 . The logger connects to a PT100

RTD temperature sensor as shown in APPENDIX A .

STYLITIS -41 USER'S MANUAL

15

CAUTION

Do not apply a voltage exceeding the maximum permissible (  20V) on voltage inputs.

Do not apply a current exceeding the maximum permissible

(  100mA) on current inputs.

Linearization is performed internally throughout a range of -50  C~+55  C. Mathematics is performed as above.

 ADVANCED APPLICATIONS OF ANALOG INPUTS.

INPUT 1:

Analog input 1 (Α1) may record voltage at the input terminal or the logger’s internal power supply. Use the [-] key (in A1’s input setup menu) to select this option.

The display shows INP or BAT. To record the battery or power supply value correctly you must enter slope=3.15 and

Offset =0. This option allows recording of the battery-discharging history.

NOTE: When BAT is selected to record power supply voltage, the internal A1 input is disconnected from the A1 external terminal.

INPUTS 3 & 4:

Analog inputs 3 & 4 may be connected to the input terminal block or use an amplifier with gain. Use the [-] key during the inputs’ setup to select this option.

The display shows INP or GAIN.

If you select GAIN remember that the slope and offset values are applied to the amplified signal.

The amount of gain is set via plug-in resistors on the data logger’s main printed circuit board, and can be changed to accommodate gains up to 1000. These two inputs can also have a 20-Ohm input resistance for use with 4-20mA sensors.

16

STYLITIS -41 USER'S MANUAL

To setup anemometer and counter parameters:

Select an input,

1-3. Then use

[  ] or [  ] to select option.

From the TYPE menu press the corresponding numeric key to change anemometer or counter input type between

Low Level AC

(SIN) and

Digital (TTL).

CAUTION

Do not apply a voltage exceeding the maximum permissible

(  20V) on counter inputs.

 COUNTING INPUTS.

There are 3 16-bit counting inputs (0-65535 counts).

There are 4 options per input:

NOT USED .

ANEM input. Selectable low level AC or pulse type.

Input frequency (counts per second) is scaled with user selectable slope and offset values: Wind speed (km/h) =

(slope x input frequency) + (offset).

Math operations include minimum, maximum, average, standard deviation.

Output (calculated) range: 0~400 user-defined units.

Resolution is 0.1 units. Examples of units are m/sec, km/h, etc.

The anemometer’s manufacturer gives slope and offset values. For instance, the NRG-Maximum #40, has a slope

= 0.765 m/sec/Hz, and an offset = 0.35.

FREQUENCY COUNTER.

No slope or offset values are applied. Math operations include minimum, maximum, average.

EVENT COUNTER.

Counts events (pulses) per averaging period.

STYLITIS -41 USER'S MANUAL

17

8. MATH PROCESSING

The analog and counting inputs selected are measured and temporarily stored once per second. Averaging intervals are selectable at 1, 2, 5, 10, 15 or 60 minutes.

Following the completion of an averaging interval, the math functions are performed and the results are stored in the internal buffer or the COMPACT FLASH card. See also, 7. INPUTS…

Math calculations include minimum, maximum, average and

standard deviation. The standard deviation is calculated using the formula:

SDV

=

n x

2

AV

2

n n

1

, where n is the number of the samples and AV the average of the samples in the averaging interval.

Stored data format for the various input types is:

Minimum

Maximum

Average

SDV

ANEM xxx.x

FREQ xxx xxx.x xxx xxx.xx xxxx.xxx xxx.x

ANALOG VANE xxx.x xxx.x xxx.x xxx.x

ANALOG xxxx.xxx xxxx.xxx xxxx.xxx xxxx.xxx

The stored data have are marked with a time stamp for extra protection. The time stamp marks the end of the statistic interval.

18

STYLITIS -41 USER'S MANUAL

9. DATA STORAGE/RETRIEVAL

Three types of storage media can be used, each one having its own strengths and weaknesses.

 INTERNAL BUFFER.

The internal buffer's size of 512Kbytes is enough for several applications. For example, to record data using one counter input and one analog input, with a 10min-averaging interval, it will suffice for 212 days. A memory card is NOT permanently required, thus reducing operating costs. Data can be retrieved two ways:

1. By placing a suitable memory card, for a few seconds,

(see below) in the slot. Data are transferred to the card and recording continues uninterrupted.

 During the acquisition in the internal buffer (with no card), you can put a card in the datalogger and clear it, if it is not clear, via the [1] button. Only after that data will be able to be recorded in the card.

 Then, the data which have already been recorded in the internal buffer will be transferred in the card almost immediately. That is, either the ‘CARD ERASED ok’ message will appear in the datalogger’s screen, in case you clear the card, or the message indicating its size will appear, along with an ‘ok’. Right next, the

‘TRANSFERING DATA’ message will appear. When it disappears, you can remove the card. If you do not,, the file which has been created in the card, and contains these data, will continue to be recorded.

 μεταφερθούν στην κάρτα, αλλά θα παραμείνουν στην εσωτερική

μνήμη.

2. By downloading buffer contents through the serial port

(see SERIAL PORT).

ADVANTAGES: Low Operational Costs.

DISADVANTAGES: Restricted size. Data loss in case of power supply loss.

STYLITIS -41 USER'S MANUAL

19

COMPACT FLASH MEMORY CARDS

The size of the above cards is enough for virtually all applications. (E.g. for data of one anemometer and one windvane, with a 10 minute interval, a 256 Μbytes card will last for 3737 months).

Each time a new card is inserted in the datalogger, it must be cleared. The datalogger warns you with the corresponding message and induces you to do so by pressing the [1] button.

Τhe card is recognized and initialized by inserting it into the

Stylitis-41 slot. A header is put on it including a serial number, the site name and the insertion time. Therefore, if you remove the card and re-insert the same one later, it will be recognized by the datalogger and you will not need to clear it.

By inserting the card in the slot of a Compact Flash card reader, connected to a computer USB port, data are retrieved via the

Opton 4 software.

ADVANTAGES: High capacity. Low cost. No Battery.

DISADVANTAGES: None.

20

STYLITIS -41 USER'S MANUAL

When acquisition is on: No parameter change is allowed.

When acquisition is off: Parameter change is allowed.

10. RECORDING & FILING SYSTEM

 Starting (ON) acquisition means:

1. Open a new file on a memory card (if one exists).

2. Start recording with the set parameters.

 Stopping (OFF) acquisition means:

1. Stop recording.

2. Close the file on a memory card (if one exists).

3. Clear the internal buffer.

 When using memory cards keep in mind the following tips:

1. Multiple files (acquisition sessions) can exist on the same card. If you stop the current acquisition and start a new one, a new file is created with a new number and a new start date and time.

2. Full cards are replaced without loss of data and without turning OFF the acquisition. In the meantime, data are kept in the buffer.

3. Accidentally removing and reinserting a card does NOT result in data loss. The system recognizes it is the same card and (provided there is space) continues storing data in a new file.

4. Only the lastly inserted card is recognized by the system.

You can withdraw and reinsert the same memory card as many times as you wish. But changing the Compact

Flash card means that recognition and initialization of a card is done only if the card is new and not used.

Otherwise, the datalogger induces you to clear it by pressing the [1] button (refer to: 9. DATA STORAGE… ).

STYLITIS -41 USER'S MANUAL

21

11. DATA POST PROCESSING

A card’s recorded data are transferred to a PC for processing when you insert the card to the slot of a Compact Flash card reader, connected to a computer USB. To save space, data are stored compressed.

Moreover, the data can be retrieved directly from the datalogger, via its serial port, either locally or via modem (see 14.

SERIAL PORT ). Via Opton 4 software, you can download data either from the internal buffer or from the card (if there is one).

When you download data from the internal buffer, (with no card), with acquisition ON, after the download, Opton 4 asks you if you wish to clear it or not.

In the second case, the recording will be continued, by incrementing the size of the internal buffer’s data file. The ‘BUFFER REMAINS’ message will appear in the datalogger’s screen.

When you download data from the card, there are two options:

1. To download a previous file, by typing its number in the Opton 4’s window. In this case, if the acquisition is ON, then the recording in the current file continues uninterrupted (it is not affected by the download).

2. To download the Compact Flash (files) Directory. Afterwards, you may mark specific files from the directory to download. Again, if the acquisition is ON, then the recording in the current file continues uninterrupted (it is not affected by the download).

3. To download the most recent file (‘Most recent file’ option). In this case, if the

 acquisition is ON, the file closes before it is downloaded and then it is downloaded.

After it has closed, a next file opens (is created), in which the acquisition continues.

Data records are decompressed to columns using Opton 4, the

PC program that comes with the unit. Further data manipulation and processing is possible using standard available software like

Excel, Axum, etc.

Optional software suitable for Wind/Meteorological analysis is also available. It accepts the decompressed output and produces graphs, tables, etc. in industry-standard format. Please contact

Symmetron for details.

12. DATA SAFETY

To ensure correct data acquisition and protect stored data and settings the power supply is continuously checked. If battery voltage is found to be less than 5.25V, acquisition stops. The acquisition restarts when battery voltage rises above 5.75V. If battery voltage falls below 5.15V the system shuts down and stops responding to external stimulus.

STYLITIS -41 USER'S MANUAL

13. PASSWORD

Stylitis-41 allows you to set a password in order to permit access to it from qualified persons only. Using the SETUP>

PASSWORD menu enter an alphanumeric word of up to 8 characters long (press [.] to enter alpha characters).

Password protection starts after the password is set and Stylitis enters Energy-Save mode. Any attempt to wake-up the data logger will result in asking for the password. If the correct password is not supplied within 4 tries, the logger will lock-up and can only be unlocked by Symmetron (either locally or remotely).

To disable the password protection you must enter 8 dashes [-] or zeroes [0].

24

STYLITIS -41 USER'S MANUAL

To connect to a standard PC serial port a

"straight" type cable is required, i.e. one which connects pin 2 of one connector to pin 2 of the other etc. Both cable connectors must be female.

14. COMMUNICATION VIA THE SERIAL PORT

The RS-232 serial port comes as standard with Stylitis-41. It allows local or remote set-up and buffer data retrieval. The user interface, as appears on the PC screen is identical to that on the data logger.

The connector is a DB9Male with the following pin assignment:

PIN 2 Transmit

PIN 3 Receive

PIN 5 Ground

Communication speed is fixed at 9600 baud with 8 data bits, 1 stop bit and no parity bit.

For the communication of Stylitis and the PC, connect the datalogger’s serial port to a computer COM port via a DB9F to

DB9F (female-female) straight cable. Next, run the Opton 4 software, by creating a local connection via the specific COM port to communcicate with the datalogger.

You can also use a modem, by connecting it to the serial port via a NULL MODEM cable for remote communication with Stylitis

(see APPENDIX D ). Furthermore, you can use Symmetron’s Sym-

o-net, by connecting the datalogger’s serial port to the DEVICE 1 port of the Sym-o-net, via a NULL MODEM DB9F to DB9M (femalefemale) cable. In this case, create a remote Diameson (GPRS client) connection via Opton 4.

For further information about the Sym-o-net and its settings and capabilities, please refer to its User Guide .

MODEM TYPES AND SETUP

1. TC35T MODEM

Disconnect the modem from the power supply. Press the yellow button on modem’s side, take out the drawer and place the SIM card (after unlocking it via a standard cellular phone). Connect the power supply to the modem. The green light should start blinking rapidly and after a few seconds, it should start blinking slowly. Finally, go to the COMMUNICATE>MODEM menu

([4]>[1]): the network operator’s name and the signal strength (SIGNAL) should appear in the display.

BER shows errors (0 or 99 is OK).

2. M20T MODEM

Follow the same setup instructions with the TC35T MODEM.

3. WAVECOM M1206/1306 MODEM

Follow the same setup instructions with the TC35T MODEM, with the following differences: The button on modem’s side is black , while the modem’s light is red instead of green.

4. SYMMETRON SYM-O-NET

Disconnect the modem from the power supply and place the SIM card (after unlocking it via a standard cellular phone). Connect the power supply to the modem. In the beginning, all 4 red

LEDs will flash continuously, while the green LED (MODEM STATUS) should blink rapidly After half a minute or so (with default settings), the MODEM and DEVICE1 LEDs will flash continuously, while the green LED should blink slowly. Finally, connect the datalogger to the

DEVICE 1 serial port and go to the COMMUNICATE>MODEM menu ([4]>[1]): the network operator’s name and the signal strength (SIGNAL) should appear in the display.

BER shows errors (0 or 99 is OK).

Example 1: R65=115000 Ohm, R66=10000 Ohm. Then GAIN = 12,5

Example 2: R65=100000 Ohm, R66=100 Ohm. Then GAIN = 1000

The gain factor of Α4 is given by: GAIN =

The resistors are placed on the main Printed Circuit Board (see picture). To uncover the Printed Circuit Board remove the 4 screws from the logger’s front panel.

NOTE: A signal requires GAIN when its full-scale value is much less than the 5V input range. For example, when a transducer has a maximum output of 100mV then a GAIN of 50 is appropriate (50x0.1=5V). Thus, you preserve high resolution of measurements.

STYLITIS -41 USER'S MANUAL

2. Analog channels A3 and A4 may be set for an input impedance of 20 Ohm.

This, together with a GAIN equal to 12,5 (see above) makes these inputs suitable current loop (0~20 or 4~20mA) sensors.

 In older Stylitis-41 models, this is accomplished by placing 20 Ohm, 0.1% resistors at position R7 (A3) and R8 (Α4) on the main PCB.

 Newer models come with R7 and R8 preinstalled. The 20 Ohm input impedance for A3 and A4 is selected by placing a jumper on headers J10 and J11 respectively (J10 and J11 are found in place of R7 an R8).

3. The +VA PULSED output is normally set for a voltage of +5V,  0.1%, the same as the other outputs. Alternatively, it is possible to output +12V or +18V for current-loop sensor supply (this setting increases the logger power consumption by about 50%).

This is accomplished by placing 2 integrated circuits (ΜΑΧ662Α στο U11 και

LP2951CN στο U16) on the main PCB. Jumpers JP1 and JP2 must also be set as in the following pictures:
