2.5 Cleaning

Use a clean, soft, dry cloth to clean the instrument and the solar cells.

To clean the instrument do not use solvents, acids, cleaning fluid, turpentine, acetone or similar products which could damage it.

It is suggested to replace air filter at least once a year or more frequently if needed.

2.6 Installation and use

The AMS-8061 Field Monitoring System consist of a vertical housing with circular shape made of material that is transparent to electromagnetic fields. Within this radome is housed the measuring device, as well as the measuring antenna and the remote communication device. Batteries are located within the power pack on the support base.

AMS-8061 power system includes high quality lead batteries which provide very good performance even in the voltage, current and temperature most severe condition. Nevertheless, as happens in all lead accumulators, capacity is influenced by temperature. Best performance are achieved around 20°C.

Installation and use 2-3

2.6.1 Installation

The AMS-8061 Field Monitor is designed to operate outdoors, in the vicinity of the electromagnetic fields sources that shall be controlled, and under the most severe environmental conditions.

2.6.1.1 Support base, feet and pole

Install the Support base on the site to be monitored

Before proceeding to permanent installation, make sure that the point at which the field monitor will be installed is adequately covered by the mobile phone service used for the GSM modem. This can be done using any GSM mobile phone capable of indicating the intensity of the signal coming from the local base radio station of the company chosen for the SIM card.

Correct readings may be conditioned by the nature of the places in which the AMS-8061 Field Monitoring System is installed. The field measuring antenna is affected by huge metallic masses or other objects that may reflect the signal, if located in the vicinity of the unit. Whenever possible, it is a good rule to install the unit at some distance from walls, high voltage pylons, buildings and other obstacles that could affect the signals reaching the sensor.

Screw the four adjustable feet under the support base.

In the northern (boreal) hemisphere, the AMS-8061 should be installed with the solar cells facing south, in order to take the best advantage of the solar radiation for continuous recharging of the internal batteries. An angle of 35° with respect to vertical is the ideal position for the solar cells to optimize solar radiation in the European latitudes, specially in winter when the light levels are generally lower than in summer.

To ensure maximum efficiency in recharging the battery and to take advantage of the maximum operating autonomy, make sure the position in which the unit is installed receives sunlight all the day long and is not shaded by buildings or other screening objects.

Page 28

2-10 Installation and use

To ensure maximum efficiency of recharging and optimum autonomy of the internal batteries, it is a good rule to keep the solar cells of the AMS-8061 clean, inspecting them periodically. If necessary, clean them with a soft cloth and a normal glass cleanser.

2-18 Installation and use

2.6.1.10 Micro SD card and led status

The AMS-8061 is a self-contained instrument which does not require any external device such as mass-storage memory. Indeed, its built-in memory is large enough to store data for a year and a half or longer than three months with a rate of 1 minute. However, the AMS-8061 supports Micro SD Cards. It is solely intended for backing up data when no other way is accessible among the many present (RS232, USB, FTP, Ethernet and MODEM-CSD). Therefore, for no reason should an Micro SD Card be left in the slot permanently, or for a long time, as its power consumption would drastically reduce the autonomy with no advantage at all. Moreover, GPS shares the same Micro SD Card port thus, when an Micro SD Card is present, the GPS is disabled.

Before removing or inserting the Micro SD card, switch off the AMS-8061.

To install the Micro SD Card:

- Slide the card into the slot

- Use your finger to gently push the card in until it stops and clicks into place.

Fig. 2-4 Slot for the Micro SD card

To remove the Micro SD Card:

- Use your finger to gently push the card in until it stops and clicks into place.

- Remove the card from the slot

In order to be used, an Micro SD Card should be first formatted, either FAT or FAT32, and then have a file named "SD8061.SD1"in the root . The size of this file, "SD8061.SD1", determines the number of record will be backed-up on the Micro SD card. According to the § 3.11 “D61 Structure, Download description”, each record takes 352 bytes. Thus to store N records the required size is 352 x N Bytes. For example, to back up 1000 records it is necessary to make the file "SDCOPY.SD9" whose size is 352000 bytes. The AMS 8061, as soon as it detects the presence of an Micro SD Card, tries to open the file "SD8061.SD1" and, if successful, tries writing the last <size_of_file> divided by 352 records having thus the most recent ones. In the above example it would write the most recent 1000 records. It is important to keep in mind that records will be aligned to last recordmost recent record.

Steady RED SD Card ERROR This can be caused by:

• SD-card not formatted FAT or FAT32

• Damaged SD-Card

Steady ORANGE SD Card ERROR This can be caused by:

• File "SD8061.SD1" not present.

• Non-Writable SD-Card

Keep in mind that when storing all tasks are suspended thus it is better to limit the size to the minimum required to avoid missing data. Once more, do not leave the SD-Card in the slot as it would not store anything more, as the storing process is triggered only by SD-Card insertion. Instead, it would stop GSP activity and draw energy reducing thus the autonomy.

2.6.1.11 Led ON in relation to the status of the monitoring station

When the monitoring station is switched on, the Led ON is first lit with a steady light for about 5 seconds, then starts to blink at the rate of one blink per second, indicating that the monitoring station is active in normal StandBy conditions and not in the low consumption mode.

The condition in which the LED blinks at a rate of one (brief) flash per second indicating that the monitoring station is in Stand-By mode and not in low consumption mode, are the following:

• All the time the Modem is on Stand-By

Even if the user will disable most of the modem functions through the software, the minimum periods at which the internal modem would be ON (first hour after switch ON without Low Battery alarm and from 11:00 to 11:45 when the “Schedule for modem” and “Schedule for SMS” are set to zero) the LED will be blinking every second

• The time between acknowledgment of a command (via RS232, USB, Ethernet) to about 60 seconds from the last command received.

• All the time between the attempts by the monitoring station to establish a communication with the antenna to about 60 seconds after correct acknowledgement of the connection.

After exiting this mode, the LED changes the manner of blinking to a (brief) flash every three seconds, thus indicating the low consumption status. The monitoring station remains in this status until an event rouses it and causes the return to Stand-by status again. Possible events are:

• Modem switched on in Programmed or Spontaneous mode

• Sending of a programmed or spontaneous SMS

• Activity on the RS232, USB, Ethernet.

As indicated above, about 60 seconds after the termination of the event, the LED resumes blinking at the frequency of 0,3 Hz.

The LED also has five additional statuses:

• It blinks at a higher frequency than once per second during a communication (from the beginning to the end) to indicate the modem is in use.

• It remains on with fixed light during data downloads.

• It blinks red when the modem is on

• It blinks green when the modem is off

• It blinks orange when the Ethernet is connected

2.6.1.12 Radome

Remove the screws from the receiver baseplate to allow the Radome mounting.

Considering that it has been designed for outdoor use and the main operations are generally performed remotely by means of an internal GSM modem, the AMS-8061 does not have any control or connection on the outside of the protective case. Controls and connections are available inside the protective case as listed onward in this manual and can be reached by removing the station Radome or the power pack cover.

The anti-tampering switch protrudes from the main unit. Insert or remove along its axis the protective case; to avoid damage the interlock do not turn the radome of the monitoring station when closing or opening.

Place the Radome to align the hole near the inner label to the corresponding one in the receiver baseplate

2.7 How to switch the GSM modem on

On the AMS-8061 the GSM modem can be switched on in three different ways:

1. Programmed (the User decides when the modem has to be switched

on and for how long).

2. Spontaneous (the AMS-8061 switches the GSM modem on whenever

there is an alarm )

3. Automatic (the AMS-8061 switches the GSM modem on automatically

when certain conditions arise)

2.8 Programmed Mode

The Programmed mode consists of setting a time for switching the modem on and off and the repetition interval.

The parameter “Hours and Minutes” specifies at what time of the day the GSM modem will be switched on and put in Stand-By mode. The “Stand-By” parameter defines for how many hours the GSM modem remains on. The parameter “Every” defines the repetition interval or after how many hours, from the last programmed activation, the GSM modem will switch on again. The parameter “Every” must be a submultiple of 24 ( 1, 2, 3, 4, 6, 8, 12, 24) in order to have every day the same timing.

2.9 Spontaneous mode

In Spontaneous mode, whenever an alarm condition occurs or when the normal conditions are restored (e.g. exceeding the threshold value set for the field intensity or returning below the threshold) the GSM is switched on directly by the AMS-8061 either to make a call or to send an SMS (depending on the settings) to the modem number(s) memorized. Afterwards, the GSM remains on stand-by for 15 minutes.

2.10 Automatic mode

The following condition turns the GSM modem on independently from the setting:

- If both Stand-By parameters (“Schedule for Modem” and “Schedule for SMS”) are settled to zero the GSM will switch on in stand by mode at 11.00 AM every day and will stay on for 3 hours, otherwise it could not be called at all.

Page 46

2-28 Installation and use

2.11 Selective unit Switching ON/OFF

The selective unit is OFF every time the battery voltage is lower than 11 V.

2.12 RF signals of dangerous intensity

The antenna used in the AMS-8061 and the receiver input stage contain highly sensitive elements. Never place the unit in an electrical field higher than the maximum allowed level. The type of the mounted antenna is automatically sensed. No operation is required after the antenna installation or replacement.

2.13 Controlling the internal battery

The internal battery is automatically recharged by the solar panel (if connected) or by an external power source. The charge can be checked by remote using the proper command; a battery alarm can also be set, if necessary.

The lead batteries with a nominal voltage of 12V can be damaged if left for a long period with voltage below 11,58 V. Below this value chemical processes, that could damage them, begin. The AMS-8061 batteries apply a technology to reduce this phenomenon. Furthermore the supply circuit disconnect the load (switching the unit off) when the battery voltage is low. Anyway, if not used, the station should be switched off. Battery should be recharged if the station has not to be used for a long period.

Any part of the instrument, including the battery, can only be replaced by NARDA, therefore in case of any damages to parts and/or malfunctions, please contact the NARDA Service Center.

2.14 Suggestions and checking list to define Area monitor problems.

The following are some recommended check points to be done to insure the proper usage of the Area Monitor:

1. Is the 8061 switched ON?

2. Is the GSM modem Led ON?

3. Is the battery charged correctly?

To charge the battery it is not necessary to switch the station on. Battery charging takes about 40 hours.

To avoid any battery problem, you can connect the battery charger to the area monitor and call it via Cable. In this way the area monitor should always respond.

4. Is the GSM modem programmed to be ON during the period you want to call the Area monitor? If not, turn the Area monitor off and ON again.

5. Can you hear the typical noise coming out from the speaker of the modem connected to the PC during the calling process? If not, your modem is probably off or the software is using a different COM port to which the modem is not connected.

6. What kind of telephone line (dedicated or GSM) are you using to call station from its PC? Try to use the fax machine telephone line.

7. Are you sure that the modem and the telephone line are able to support data calls?

8. Is the modem or the RS232 Cable connected to the correct COM port of the PC?

9. Is the modem correctly installed on PC (hardware and software)?

Use diagnostic procedure to verify the correct installation and be sure the modem has all the protocols required for this kind of data communications – low cost modem for internet application only, may not support Area Monitor application.

10. Is the SIM Card in the Area Monitor available for Tx and Rx data communication from mobile to mobile? Has the PIN code been removed?

If the communication with the area monitor is successful only by RS232 cable, the problem may lay on the modem or its antenna

If the modem of your PC is used as Windows “Fax Printer” peripheral it may be not available for the station. In this case, disabling the setting for the use of the modem in the “Fax Printer” will restore the normal operation.

To get a fast response from NARDA support center it is very important to provide always a picture reporting the system setup (storing settings, alarms status, start and stop of the download, etc..) to give a correct description of the conditions under which the area monitor was working during the faulty of the unit. Better if you can also provide the telephone number of the area monitor (A SIM card allowed for international data calls should be available for remote diagnostic). Remote diagnostic will offer a better understanding of all problems concerning the status of the Area monitor and to eliminate your local communication problems.

GPRS and FTP 3-1

3 – GPRS and FTP

3.1 Introduction

As opposed to point-to-point Modem connection, which needs that both uploader and downloader are connected at the same time, GPRS via FTP mode works instead on a server way. Indeed, the monitoring station regularly stores all data on a server while a client application can retrieve them later on. This means there is no necessity to be on-line at the same time. Moreover, more clients can share the same data as all data are stored in a server and stay there until they are deleted (by a client). The method used is FTP.

Similarly to MODEM GSM schedule, which dials a remote Modem number stored in AMS-8061 telephone directory, GPRS establishes a connection using Provider Name, Username etc. stored in its memory.

Basically, at schedules, the AMS-8061 regularly establishes, via GPRS, a connection to the server and through FTP:

• First it loads, if any, all the (new) settings which have been written by the (client) application.

• Then it writes all data that have been requested by the application.

• Finally it erases all previous required settings in order to avoid reloading them at the next connection. Note that data related to field measurements are never deleted by the station.

After that the connection is terminated.

Although the AMS-8061 can operate in both modes, MODEM and GPRS, it cannot do it at the same time. This means that a setting command is used to configure the AMS-8061 to work either via MODEM way or via GPRS.

3-2 GPRS and FTP

3.2 Structure

All data exchange is done on the directory named as the serial number of the monitoring station itself. That is in order to avoid having multiple stations that store on same directory and, at the same time, having a unique location. Here, an example of directory structure: FTP_Root

000WE80201

8061.CFG

8061.set 8061FLD.TXT

17_08_01_07_09_.D61

000WE80202

8061.CFG

8061.set 8061FLD.TXT \ 20_00_01_07_09_.D61

The User must ensure that the directory is already present on the FTP root as the AMS-8061 will not create it.

Page 51

GPRS and FTP 3-3

3.3 Configuration (read)

Whenever the AMS-8061 connects to GPRS and accesses to FTP, it looks for a file named 8061.CFG in its directory (its serial number). If the file is present, the AMS-8061 retrieves it and calculates the checksum in order to use it and thus get the new configuration. If the checksum is wrong, the file is discarded otherwise the new configuration is taken. Is important to note that the new setting will not take effect immediately but only after the connection is closed.

All figures are Little Endian notation unless differently specified.

3.4 FLD File (Read) After having dealt with the configuration file 8061.CFG, the AMS-8061

check for the presence of a file named 8061FLD.TXT. This is an ASCII file which contains the date of the first requested record and the number of them. The syntax is: FLD HH:mm;GG/MM/YY;n where:

• HH is hour of the day.

• mm is minute of the day.

• GG is the day.

• MM is the month.

• YY is the year

• n is the number of records required (if n=”---“ then all records

starting from the date/hour up the last recorded record will be uploaded).

For example the string FLD 18:13;23/04/14;100 Asks for 100 records from the 23

of April 2014 at 18:13.

If, instead, the string would have been FLD 18:13;23/04/14;--- It would ask for all records from the 23

of April 2014 at 18:13 up to now.

in case of “---“ (up to now option), in order to avoid huge files and long transfer time, the number of records will be limited to 5000.

Once the AMS-8061 has read the file 8061FLD.TXT, it deletes it. It will be

replaced later with the newer self created 8061FLD.TXT which reflects the last record. This solves the continuity of records even without any external intervention. Indeed, for every connection the AMS-8061 uploads the records and writes a new FLD file which reports the date/hour of last record so that next connection will continue from this having thus an uninterrupted series of records.

Page 55

GPRS and FTP 3-7

3.5 Record File (Write)

After having read the FLD file, which informs the AMS-8061 about which records have to be uploaded, it writes a file named HH_mm_GG_MM_YY.D61 where:

• HH is hour of the day.

• mm is minute of the day.

• GG is the day.

• MM is the month.

• YY is the year

The content of this file is binary and reflects what is described, according to the setting, in the specific paragraph:

• D61 Structure

Please refer to it for the correct interpretation of data.

3.6 FLD File (Write) After having written the record file HH_mm_GG_MM_YY.D61, the AMS-

8061 writes the file named 8061FLD.TXT which replaces the old one. This is an ASCII file which contains the date of the last uploaded record and terminates with the string “---“. The content will be therefore: FLD HH:mm;GG/MM/YY;--- where:

• HH is hour of the day.

• mm is minute of the day.

• GG is the day.

• MM is the month.

• YY is the year

For example the string FLD 20:30;23/04/14;--- Says that the last updated record is related to the date of 23

of April 2014

at 20:30.

If a client does not necessitate a specific period, and needs a simple continuous data logger, there is no need to write any FLD File as the system is self-sufficient.

3.7 Event File (Write)

After having written the FLD file, the AMS-8061 writes a file named HH_mm_GG_MM_YY.TXT where:

• HH is hour of the day.

• mm is minute of the day.

• GG is the day.

• MM is the month.

• YY is the year

Which represents the events file. This is an ASCII file which contains all the new events since last connection. Alternatively, soliciting a connection, by the SMS command, different event history can be retrieved as follows:

• SCGNA : all the stored events are written in EVENT.TXT file

• SCGNL : The last 20 events are written in EVENT.TXT file

The content of EVENT file is the chronological history of all events up to the time of connection (RTC setting assumed to be correct).

Page 56

3-8 GPRS and FTP

3.8 Setting Status. (Write)

After having written the EVENT.TXT file, the AMS-8061 writes a file named

8061.set which reflects the configuration of the monitoring station. Similarly to the Configuration 8061.CFG the file is binary. This file is solely intended for reading as it is ignored by AMS8061 and therefore any change of it will be discarded. Use 8061.CGF if you want to change any setting.

All figures are in Little Endian notation.

The structure of the configuration file is as follows.

3.9 GPRS – FTP Settings

In order to establish a GPRS connection and a FTP transfer, a number of data are required which are divided into 2 main fields as follows. Each fields cannot be more than 31 characters. These commands cannot be executed via FTP/GPRS (because they would need to be already correctly set).

GPRS Connection Data

Field Description Setting command

Command to be issued by

either SMS or RS232

GPR0

APN Access Point Name

The provider name of the GPRS bearer.

#SMSGPR0 <apn>* where <apn> is Access Point Name Example: #SMSGPR0 web.omnitel.it*

GPR1

GUN

User Name for Gprs access

The User Name required for logging-in. Sometimes this field might not be required and thus can be left empty.

#SMSGPR1 <gun>* where <gun> is the User Name of GPRS access. Example: #SMSGPR1 MyGPRS*

GPR2

GPSW

Password for Gprs access

The Password required for logging-in. Sometimes this field might not be required and thus can be left empty.

#SMSGPR2 <gpsw>* where <gpsw> is the Password of GPRS access. Example: #SMSGPR2 1234*

FTP Connection Data

Field Description Setting command

Command to be issued by

either SMS or RS232

GPR3

FUN

User Name for FTP access

The User Name required for accessing to the FTP server. This word is usually issued from the FTP administrator and is nothing to do with the bearer.

#SMSGPR3 <fun>* where <fun> is the User Name for FTP. Example: #SMSGPR3 MyFTP*

GPR4

FPSW

Password for FTP access

The Password required for accessing to the FTP server. This word is usually issued from the FTP administrator and is nothing to do with the bearer.

#SMSGPR4 <fpsw>* where < fpsw > is the Password for FTP. Example: #SMSGPR4 abcd*

GPR5

FIP

FTP IP Address

This parameter is the server address for FTP ( IP Address of FTP). Normally this is the static IP Address that routes the file transferring process to the wanted server

#SMSGPR5 <fip>* where < fip > is the IP Address for FTP. Example: #SMSGPR5 194.183.2.17*

SMS or RS232

CGN

Connect GPRS Now

This command starts a GPRS connection immediately. All the procedures are then the same as it would for a scheduled connection.

#SMSCGN*

CGNL

Connect GPRS Now (Last Events)

This command starts a GPRS connection immediately as for CGN but it forces to have a EVENT.TXT file containing the last 20 events instead of the most recent, and not yet loaded, ones.

#SMSCGNL*

CGNA

Connect GPRS Now (All Events)

This command starts a GPRS connection immediately as for CGN but it forces to have a EVENT.TXT file containing all the events available instead of the most, and not yet loaded, ones.

#SMSCGNA*

CGNFW

Connect GPRS Now and update Firmware

This command starts a GPRS connection immediately as for CGN. Additionally, if the 2 firmware files are found, it updates the firmware and reboots.

#SMSCGNFW*

CGNFWI

Connect GPRS Now and Immediately update Firmware

This command starts a GPRS connection immediately as for CGN. Additionally, if the 2 firmware files are found, it updates the firmware and reboots without uploading any records. The difference from CGNFW is that it does not upload the data before updating the FW thus all unloaded records are lost.

#SMSCGNFWI*

NETE

Enable GPRS protocol

This command enables the AMS-8061 to connect via GPRS instead of point-to-point GSM-MODEM connection. The reply is the same as for command ?TSM

#SMSNETE*

NETD

Disable GPRS protocol

This command disables the AMS-8061 GPRS and enables point-to-point GSM-MODEM connection. The reply is the same as for command ?TSM

#SMSNETD*

STS id

Set Timedate SMS

This command sets the internal real clock time by using the SMS provider’s information. To use it id (the AMS-8061 telephone number) must be sent. This command works assumes that the SMS provider gives the correct Clock/Date and its feedback is within 30 seconds. The reply is sent only if the real time clock has been updated and is the same as for the command “?CLK”

#SMSSTS nnnnnnnn* where nnnnnnnn is the telephone number of AMS-8061

3.10 Checksum algorithm

As previously mentioned, there is a little endian 16 bit unsigned int which is called checksum. The checksum is intended for verifying the reliability of the array read mainly from the AMS-8061’s side as a corrupt configuration could potentially make the AMS-8061 ineffectual. Therefore the application must ensure that the checksum in the 8061.CFG file reflects the actual state of the configuration setting. Otherwise, if the checksum does not match the exact value, the new configuration will be ignored.

The Checksum is calculated as the sum of all the bytes involved starting from a seed of 0xAAAA. Then, from the result the modulo 0x10000 is taken (which also means truncating the result to 4 bytes).

3.11 D61 Structure, Download description

This paragraph describes the structure of a multiband record. These records are created by either GPRS/ftp enabled (files D61) or “?FLS” command.

3.11.1 Command Mode

Sintax Description

?FLS HH:mm,dd/MM;n

Request for n samples starting from Hour HH and minute mm of the day dd of the month MM of the current year. In case MM is higher than current month, the referred year is the past one.

For example, the command #SM ?FLS 13:00,01/08;60* asks for 60 measures starting from 13:00 of the 1

of August

This answer is a block of binary data

The block of bytes in replying to #SM ?FLS HH:mm,GG/MM;n command

is as follows:

A Header: made of #SM FLS=*<CR><LF> (11 bytes) A series of ( 32 bytes + 16* Number of Bands) per sample as shown in the following table. A final Checksum as described at the end of this document.

3.11.2 GPRS/FTP Mode

At GPRS schedule a file named HH_mm_dd_MM_yy_.D61 is created (see the proper paragraph in this chapter). This file contains ( 32 + 16* Number of Bands) * n bytes (where n is the number of requested records).

• USB When High it flags that the USB connection was ON during sampling.

• CHG When High it flags that the external Charger was connected by cable during sampling.

• ETH When High it flags that the Ethernet connection was ON during sampling.

The presence of one of the above flags indicates that the record has been perturbed by external influence and the result, in the best case, could be unreliable.

Byte 15/16

DateTime

DateTime should be considered as a little-endian unsigned 16 bit integer and indicates how many

minutes have been elapsed since the beginning of the current month (previous MONTHS data). If, for example, DateTime is 0x95AE (decimal 38318) then the record will be related to the 27

of the month at 14:38. Indeed : Day = 1 +Int(DateTime / 1440) = 1 +Int ( 38318 / 1440 ) = 27 Hour = Int((DateTime Mod (1440)) / 60) = Int ( ( 38318 Mod (1440 ) ) / 60 ) = 14 Minute = (DateTime Mod (1440)) Mod 60)= ( 38318 Mod ( 1440 ) ) Mod 60 ) = 38

Merging the data with MONTHS we can get the full date of acquisition which is 14:38 27/05/2015

The figure named Longitude Fract is a little-endian unsigned 16 bit integer and indicates the fractionary part of the GPS Longitude and it is expressed in Ten-thousandths of a minute. Merging the previous data Longitude int and this figure the full Longitude can be obtained. If, for example, Longitude int=0x0809 and Longitude Fract=0x16b3 then the GPS Longitude would be: 8 degree, 09.4777 minute East. Note that position is valid only when Flag V of Latitude int is zero.

NOB is a 5 bit unsigned integer which indicates how many bands have been measured and present in the current period. Based on this figure, starting from the 33

byte, then 16 bytes for each band will

follow. If NOB is out of the allowed range (1-20), such in case of an empty record, NOB should be considered to be 0 (no bands recorded) and thus the 33

byte is in fact the 1st byte of the next record.

OldData is a bit which flags whether the following data are still the same or are fresh ones. When OldData is 0 then data have been updated since the previous record otherwise, OldData is ‘1’, data have not completely updated yet. The latter is the case when the energy is low and the measuring process is reduced in rate to save power.

DivExp Index

This figure (RBW) gives two figures:

• the Index of RBW used. Index is a 4 bit unsigned integer.

• DivExp is a 4 bit unsigned integer and express the exponent of the Scaler. Scaler=10^(DivExp-

2).

For example, if RBW=0x31 then Index=1 and DivExp=3. Therefore, Scaler=10^(3-2) = 10.

Peak

Byte +10/+11

16 bit unsigned integer

It is the Peak value detected in the stored interval, of field strength measured in the band. The number should be considered as a Little-endian unsigned 16 bit integer multiplied by the Scaler above calculated. In the particular case in which the figure Peak is equal to 0xFFFF then Peak value must be considered invalid (AMS-8061 was not able to get a measurement) and the data are meaningless. If, for example, 16 bit figure named Peak is 325 and the Scaler 0.01 then the PEAK field strength value related to the band will be 3.25.

The 16 bit figure named Avg is shown as follows:

These (32 + 16 * NOB) bytes above described constitute the block containing all record data related to the interval. Therefore, the number of blocks sent are as many as the required sample (asked by n parameter) by the command:?FLS HH:mm,dd/MM;n or, when GPRS/ftp enabled, through the file 8061FLD.TXT (see the proper paragraph in this chapter).

Then, according to the mode used, either command or ftp, the behavior is as follows:

Command query (?FLS HH:mm,dd/MM;n).

As soon as all records have been sent an additional byte (8 bit) is appended. This additional character represents the checksum of the just sent packet. This checksum is calculated summing up all received bytes and making then modulo 256. This can be helpful for checking the transmission correctness. The reply starts with the header (“#SM FLS=*\r\n”), and it is followed by the above mentioned packets of (32 + 16 * NOB) per each sample plus 1 byte of checksum.

As the monitor station, when sending data, suspends all other tasks ( sending data gets highest priority) storing included, it is preferable asking not many data at once so that the AMS-8061 is not engaged, for say, for more than 10 seconds. Therefore, when having a lot of data to retrieve, it is better to split up into consecutive smaller requests instead of asking the whole block so that the AMS-8061 can service its own tasks in between them. On the other hand, the overall transmission time will not be significantly influenced as few millisecond are needed for sending a new command.

GPRS/ftp mode (8061FLD.TXT file).

At GPRS schedule a file named HH_mm_dd_MM_yy_.D61 is created (see the proper paragraph in this chapter). This file contains n*(32 + 16 * NOB) bytes (where n is the parameter present in the file content (FLD HH:mm;dd/MM/yy;n)

4 - SMS Messages and Commands

4.1 Introduction

This Chapter includes a list of commands which can be sent to the AMS-8061 in the form of SMS, by means of a mobile phone, or directly by serial connection (RS-232 cable or modem), USB and Ethernet.

Because of their text length, some commands cannot be used via SMS, such as: ?EVN, ?EVNL, ?EVNR, ?BNDALL.

When any password is set in the Station, it is necessary to add the ?IDN (or ?IDNF) command before of any other one to be sent.

Username and Password must only contain alphanumeric characters; any special characters are not allowed.

As for example, to ask for the last field measurement, the query SMS

would be: #SM?IDN password* #SM?LFA*

Commands allow the user to set several parameters and ask for data or information about the station status.

Commands have the following syntax:

#SMQCommand(parameters)* where:

# = command string start character; SM = SM always present to distinguish the model; Q = ? for query commands; S for setting commands; Command = command string; (parameters) = setting parameter (where needed);

* = command string end character.

Commands are divided in two main categories:

• Query COMMANDs;

• Setting COMMANDs.
