INTRODUCTION

This document is a guide to implement a wireless communication between the ML250 and a base station.

POWER CONNECTIONS AND REQUIREMENTS

The ML250 is powered by its internal battery or an external power supply in the allowed range (see manual). The ME44 communication module uses a separate battery pack that serves only the module. The main unit controls the power to the communication module and turns on and off it whenever necessary. The battery status of the ME44 module is monitored and reported in the event logger. WARNING: Never remove the module ME44 from the main board before the power is completely switched off on both the units, main board and module. Never remove the antenna, the cable or the connections when the system is in use or powered. Always disconnect the batteries when servicing the units. Failing to do so may result in serious damage to the unit and/or the personnel. THE battery are supplied by the factory : any other type can damage and/or to cause problems to the instruments.

SET-UP, PRECAUTIONS AND IMPORTANT NOTICES

Preliminary operation on the SIM CARD

The SIM card that must be plugged in the instrument has to be pre-programmed externally in order to make the system working. For the programming operations, a normal cellular phone can be used. Insert the SIM in the phone, turn on it and wait until the unit is registered in the network. If the SIM has the PIN code enabled, it MUST BE DEACTIVATED. Follow the instruction of the phone to disable the PIN code of the SIM card. When the PIN request is disabled, try to turn off and on again the phone: it should not ask the PIN code anymore. When this step is done, check the number set for the SMS MESSAGE CENTER: it should correspond to that indicated by the company that provided the SIM card. If different from that, it must be set to the right value, otherwise no SMS can be sent by the unit. When done, try to send and receive some test SMS. When successful, the SIM set-up is done and it can be inserted in the instrument.

After the installation of the sensors and the cables, before to switch on the instruments follow the instructions below:

NOTICES: before to power-up the unit, be sure that everything is firmly in place and properly fixed, especially the antenna cable. Be sure that this cable is not pinched, scorched or torn apart and that is correctly connected on both sides. During powering-up, the system try to register itself to the wireless network, this phase is indicated by the display of the instrument. If the SIM card is not inserted correctly or it is not valid for the network, the system will try to register itself in the network in an endless loop every 60 seconds. Be sure that the module can be registered, otherwise the data cannot be transmitted and the battery life will be shortened in few days. The communication module has a blue LED that can display the following status:

LED off: the module is in stand-by mode, detached from the network and powered down. LED fixed on: the module is registering to the network or it is attached to the network in a TCP/IP session LED blinking slow: the module is registered to the network and powered on, awaiting for commands. LED blinking fast: the module is sending or receiving SMS.

* Insert the SIM card like suitable aside (polarized side on left)

CONNECTING THE ML250 TO THE HYPER-TERMINAL APPLICATION

For to modify most of the communication-related parameters it is necessary to connect the ML250 to a terminal capable to display and to send simple text commands via a RS232 line. This set of commands are specific to the communication and CANNOT BE ENTERED USING THE STANDARD DISPLAY/KEYBOARD SET OF THE INSTRUMENT OR THE IF2 INTERFACE PROGRAM. A standard application suitable for this purpose is the Windows program “HyperTerminal”. To connect the ML250 to the HyperTerminal, ensure that the IF2 cable is connected on both sides (to the ML250 and the PC) and that the ML250 is alive and operating normally. On the ML250 side, set the function “IF2 prot.= HTP” on the menu “7-Communication”, be sure to do this, otherwise the communication will not work. Start the HyperTerminal application and set its property as follows: Ø COM port: select DIRECT CONNECTION with the port where the IF2 cable is plugged and open the dialog for configuring the port, set the

following property: • Bits per second: 38400 • Data bits: 8 • Parity: none (no parity) • Stop bits: 1 • Flow control: none (no control lines nor xon/xoff characters used)

Open the Settings tab and set terminal type as “ANSI”, leave all parameters set as default, open “ASCII setup” dialog and check the following: • ASCII Sending: check the “Send line ends…” box • Line delay: set to 1000 milliseconds • Character delay: set to 10 milliseconds • Verify that the box “Echo typed characters locally” is UNCHECKED, if it is checked, uncheck it • ASCII Receiving: check the last box “Wrap lines…”, all others must be unchecked

When the settings are finished and if it is not yet on-line, click on the icon “connect” and if you want, save the settings with a new name. Try to type the command MODSV? and confirm it pressing the “enter” key. The ML 250 should respond with its model name and software version. If the ML250 doesn’t respond, verify that it is alive and all the connections and the settings are ok. Try also to send the command more times, since the ML250 may shut down the communication automatically when it detects no line activity for more than 30 seconds. When the communication is successful, the system is ready to enter the configuration data, as explained in the next section. It is also possible to retrieve and to save the complete set of configuration parameters of the instrument. To do so, select “Transfer” on the menu bar of the Hyper terminal and choose “Capture text”. Give a file name in the dialog box that will appear. Write on the screen the command “ACODE=xxxxx,CFLST?” , where xxxxx stays for the Level 2 code set in the instrument, and press “enter”. You will see a series of lines scrolling on the display. When the listing is finished, go to the “Transfer” menu, select “Capture Text” and finally “Stop”. The file saved contains the complete configuration list. If now you want to set the complete parameters list into the instrument, proceed as illustrated:

• Open the saved file with Notepad or similar application and delete the first and the last lines, where you see the “ACODE=xxxxx,CFLST?” command and the “0:OK” answer.

• Save the modified file and close the Notepad application. • Send the following command to the instrument: “ACODE=xxxxx,L2ACD=0”, where the xxxxx stays for the actual L2 code set in the

instrument. This disables the Level 2 code, otherwise it should be necessary to repeat the command “ACODE=xxxxx” at each line. • Select “Transfer” on the menu bar of the Hyper terminal, and choose “Send Text”: a dialog box window will appear • Set the filename that you have modified before as the file to be send in the dialog box and press “enter” • The display will show a series of lines scrolling, with all the configuration parameters contained in the file. • Wait until the last command is sent. • Eventually set again the Level 2 code with the command “L2ACD=xxxxx”. Do not forget the code entered now!

NOTE: some commands sent with this method probably will fail with a “1:CMD ERR”, “2:PARAM ERR” or “5:ACCESS ERR” message. This is normal because some parameters can be read at certain access level but they can’t be written at the same level, or some others can be read but they can’t be written in the actual configuration context.

HYPER TERMINAL PROTOCOL (HTP protocol)

The HTP protocol (with only one “T”, to be not confused with the HTTP protocol, which is a completely different thing) is a very simple way to exchange data between the ML250 and an application like the Windows-based Hyper-Terminal. With the HTP protocol it is possible to read and to write the parameters of the ML250 and to perform some internal functions. The data are exchanged using ASCII strings terminated by the carriage-return character. The maximum size of the input or the output strings is about 1000 characters when a terminal is attached directly to the serial port, or 160 characters if the communications is performed using SMS. When the maximum size is exceeded in the input, the entire string entered is discarded and an error message is issued. When the maximum size is exceeded in the output, the execution of the commands is still performed but the output information are lost and an error message is issued. The output string length depends exclusively on the type of commands given in the input, some commands produces a very short answer and some other gives a very long string. Care must be taken to not saturate the output capacity, otherwise the expected information will be lost. IMPORTANT: Before accessing or modifying some parameters, a privilege level must be acquired. This can be done sending an access code that matches the L2 code of ML250 as first command in the input string (ACODE=n). The code lifetime is limited to the execution of the string that contain it, when the input string is evaluated completely, it expires. Thus it is necessary to provide the access code each time a parameter must be changed or inspected. If the L2 code of the instrument is set to zero, the access code is no more necessary.

TECHNICAL MANUAL


ISOMAG

Special characters The following characters have special meaning in the protocol and thus they can’t be used for other purposes:

• <CR> carriage-return character, value 13 decimal, 0D hexadecimal, terminates the input string and starts the elaboration • <LF> line-feed character, value 10 decimal, 0A hexadecimal, may follows the <CR> but it is never considered • ? question mark character, value 63 decimal, 3F hexadecimal, it is an operator character • = equal sign character, value 61 decimal, 3D hexadecimal, it is another operator character • : colon character, value 58 decimal, 3A hexadecimal, it is the comment-separator character • , comma character, value 44 decimal, 2C hexadecimal, it is the command-separator character

General input syntax.

The information are entered in the ML250 as text line strings, with one or more command-sequences terminated by the <CR> character. The command-sequences are executed in the same order as they are found in the string. The execution of the commands contained in the input string does not start until the <CR> character is received. The optional <LF> character that may follows the <CR> is not considered but it is accepted because usually the Hyper-Terminal or similar application sends also this extra character when the <CR> is sent. As a rule, an input string is composed of one or more command-sequences, terminated by the <CR> character and an optional <LF> character. The command-sequence is composed by the following elements, exactly in this order:

• A five-letter mnemonic command, always present • An operator, always present • An optional value, present only when requested by the operator type • An optional comment-separator, may be present if it is also present the value • A comment, present only if it is also present the comment-separator • An optional command-separator, present only if another command-sequence follows it

With the exception of the comment element, no other extra characters or spaces are allowed in the command-sequence. Command. The commands are always represented by a five-letters mnemonic code and are case insensitive, so for example the command MODSV can be written “MODSV”, “Modsv”, “modsv”, “mOdSv” and in any combination of upper / lower case letters. Operator.The operators permit to choose one of the three possible functions associated to the command at which they are attached and they are:

• READ, indicated by the ? symbol. It is used to read values. • SET, indicated by the = symbol. It is used to set values. • HELP, indicated by the =? sequence of symbols. It is used to display a set of options or a range of permissible values related to the

command. Value. The values can be numbers, strings or special formatted fields like the date / time or the IP addresses, depending on what it is expected by the command. Numeric values are always checked for validity range and strings are checked for length. IP addresses and date / time fields are checked only for the correct syntax but not for the values, so please be careful, because in case of misspelled characters or wrong numeric values the result may be different from what it is expected. In case of floating-point numbers, the decimal point symbol to be used is the dot (.), not the comma (,). Comment-separator. This is an optional element and it is indicated by the : symbol. Comment. This element may be present only when the value to input belongs to a list of options, composed by numbers and descriptions. Normally the user doesn’t have to supply both, but in case of copying and pasting some values coming from a previously listed configuration, this ensures the full compatibility between the output and the input formats. Command-separator. This element is required when more than one command-sequence is submitted in an input string and it is indicated with the , symbol. For each command-sequence recognized and executed, the ML250 returns one of the following output types, depending on it:

• a result code, when a function execution was requested • an expression, when a parameter or a process data value was requested • a list of options or a range of values, when an help on a parameter was requested

Each answer is separated from the other by the comma symbol (the same used as command-separator). The complete output string is terminated by a <CR><LF> sequence. Unrecognized command-sequences are silently discarded without response and without halting the execution of the next sequence, if it is present. Illegal parameter’s values and operations performed in wrong contexts are reported and identified by error codes. Result-code. The format of the results is the following: code-number:description, without any blank spaces separating the number from the description. There are six possible result-codes:

• 0:OK, the execution was correct • 1:CMD ERR, wrong context, execution was not possible due to a configuration limit or wrong working conditions • 2:PARAM ERR, the expected parameter was out of the allowed range • 3:EXEC ERR, the execution of the command was not successful due to an internal error condition • 4:RANGE ADJ, the entered parameter caused an internal automatic adjustment on other ranges • 5:ACCESS ERR, the execution of the command was not possible due to an insufficient privilege level • 6:BUFFER FULL, the input or the output strings exceed the maximum allowable space.

ISOMAG

PARAMETERS SET-UP As explained before, there are some parameters that is possible set by the ML250 key board and some other that is possible to set only by Hyper terminal program. In order to activate the GPRS/SMS system, it is ABSOLUTELY NECESSARY TO set the following parameter by the HYPER TERMINAL : IMPORTANT NOTICE : There are no default values, ALL parameters MUST be checked and entered carefully, otherwise a complete system malfunction can occur.

GLOBAL PARAMETERS. To ensure the correct working of the entire system, the following parameter MUST be already enabled by factory settings and can be inspected by the display of the instrument: “GPRS modem = ON” on the menu “11-Internal data”, this must be enabled in order to activate the communication. ( THIS MUST BE ENABLE ONLY BY THE FACTORY !)

GPAPN=access point name, this parameter is the name of the access point context specified by the wireless operator and must be asked to the company. For example, the value for Italian wireless network operators are the following:

• Omnitel Vodafone: web.omnitel.it • Wind: internet.wind • TIM: ibox.tim.it

GPUSR = access user name, this specifies the user name for to access the wireless network, it is not necessary in most cases (none of Italian companies required it). GPPSW=access user password, this specifies the user password for the network access, normally it is not needed (none of Italian companies required it). GPAUT=n, network access authentication scheme: 0=Normal (PAP), 1=Secure (CHAP), 2=None. Consult the local wireless operator to set the right value, in Italy this value can be set to 2 (none). PARAMETERS NEEDED FOR E-MAILS SENDING. The following parameters are necessary to configure the access and the correct functionality of the e-mail system: • GPSMA=xxx.xxx.xxx.xxx, this specifies the IP address of the e-mail SMTP server, as for example GPSMA=83.224.64.20 • GPSMP=xxxxx, this specifies the TCP port used for the connection with the mail server, normally this port is set to the value 25 for SMTP

servers, as for this example: GPSMP=25 • GPEMF= [email protected], e-mail address that will be specified in the “mail from” field. This is the address that figures to be the

sender of the message. It is VERY IMPORTANT that this address is a valid existing address because in case of errors, the mail server can send a reply to this address. For example it can be set to a specific address of the control center used to signal errors.

• GPEMT= [email protected], e-mail address of the control center at which the e-mails of the ML250 will be sent. • GPESE=1, this enables the automatic e-mail send function of the ML250

WHEN THE OVER PARAMETER ARE SETTINGS CORRECTLY, THE SYSTEM IS READY TO OPERATE !

Example of how send an e-mail Set : - DLYSE = 1 (Enables the sending of the dynamic data logger’s data by email)

- DLOGE = 1 ( Enables the logging functions for data ) - GPDTS=1 (Sends an email)

On the display will appear : Modem setup ; GPRS Setup ; SMTP Setup ; Connect ; Sending DDL ; Email Sent You will receive, at the setting address ( [email protected] ) one e-mail as descripted below :

- object : ML250 xxxxx ( xxxxx = board serial number ) - file : ______DD________XXXXX______YYYY______MM_____DD_____HH_____mm_____SS____.CSV

(Dynamic data) (board s/n) (year ) ( month ) ( day ) ( hour ) (minute) (second)

PARAMETERS NEEDED FOR SMS OPERATIONS. The following parameters are necessary to configure the access and the correct functionality of the SMS system: • GPSME=1, this enables the SMS operations • GPSCI=n, this specifies the interval at which the system wakes-up and performs the check of new SMS arrived, the parameter n can be:

0=1h, 1=6h, 2=12h, 3=24h. • GPASN=n, this parameter specifies an authorized phone number from which the SMS can be received and interpreted. If this parameter

is set, all incoming SMS are checked for the caller ID, if it matches, the SMS is processed, otherwise it is not. The checking mechanism allow also access from different contiguous numbers, as illustrated in this example:

• Example 1: n = +391234567890, this match exactly the number +391234567890 • Example 2: n = +39123456, this matches all numbers from +391234560000 to +391234569999 • Example 3: n = +39123, this matches all numbers originating from +39123 prefix • Unauthorized SMS are recorded as events, but the caller number is NOT stored because of memory limitation. • BE SURE TO CONFIGURE CORRECTLY THIS PARAMETER, otherwise no SMS can be received by the instrument. • ENSDT=time, this specifies the time spent waiting for an incoming SMS. The same time is used as display / keyboard timeout function

and normally is set to 60 seconds. This time must be set as short as possible, because this increase the power drawn from the batteries, but not too short to avoid to receive the incoming SMS from the network. When the unit turns on and registers itself to the network, some time must elapse before the incoming SMS can be delivered to the unit. This is network-dependent.

WHEN THE OVER PARAMETER ARE SETTINGS CORRECTLY, THE SYSTEM IS READY TO OPERATE !

TECHNICAL MANUAL


ISOMAG

Example of how send an SMS

Try to send the following address to the ML250 (using the SIM number!) : MODSV? The ML 250 will give you the answer :

ML250X.XX (X.XX = software version) When instrument it is turn on and the current configuration determines that the modem has to be activated, on the display appears: MODEM SETUP..... In this step the modem it's turn on. Are necessary about 6 seconds for this operation

NETWORK SETUP.... REG.STATUS: N, S

In this step the modem try to access on network. The time is varying from zero to 30 seconds, depends from the operator and network conditions. The characters N e S have the following meaning:

• S: timer in seconds, countdown from 29 to 0. If arrives to zero and the modem not results still registered to the network, it turn off and the registration will come retried to the next turn on.

• N: registration status, with the following codes: • 0: not ON-LINE, the research of the network is NOT running for hardware problems in the module. • 1: ON-LINE, finished registration with the telephone operator of the SIM card • 2: not ON-LINE, compatible telephone operator research in course • 3: expressly forbidden registration from the SIM card telephone operator • 4: registration in course, evaluation of the signal • 5: ROAMING: registered with different operator

Only the code 1 consents to access to the network. The code 5, is disabled from the software. When the modem turn on and registered to the network, on the flow rate visualization is shown up on right the character "Y", otherwise is shown "1" (flow rate scale ) .

If the meter there isn’t in energy saving and the modem doesn't succeed registration, an attempt every minute is repeated.

The following parameters allow to SYNCHRONIZE the data/time of ML250 with “master” clock.

PARAMETERS NEEDED FOR CLOCK SYNCHRONIZATION. The following parameters are necessary to configure the access and the correct functionality of the clock synchronization capability: • GPCSE=1, this enables the clock synchronization with a specified server via the HTTP protocol. • GPHTA=xxx.xxx.xxx.xxx, this specifies the IP address of the HTTP server, as for example GPHTA=83.224.64.20 • GPHTP=xxxxx, this specifies the TCP port used for the connection with the server, normally this port is set to the value 80 for HTTP

servers, as for this example: GPHTP=80, but BEWARE: some GSM operators, like Vodafone here in Italy, reroute all the http calls in the port 80 to their proxy server, making the connection unusable. To solve this, simply specify another port, like for example 10080. Obviously the same port must be also opened in the http server.

• GPURL=anyurl.shtml, this parameter specifies the full path name of the document to be fetched in the http server WITHOUT the initial “/”. This document is a “shtml” type of document and need to be created automatically by the server at the time of call (of course, otherwise the time value contained it is meaningless!). To do this, a document containing ONLY one of the following string must be created:

For YYYY/MM/DD time format, active when ML250 is set to English layout language: DTIME= For DD/MM/YYYY time format, active when ML250 is set to ALL BUT English layout language: DTIME=

The document extension MUST be “.shtml” and the server MUST have the SSI (Server Side Includes) mechanism enabled and active for the directory where the document is saved. For more information on SSI mechanism, please consult the documentation about the http server to be used. KNOWN IMPORTANT LIMITATION. The data buffer used to exchange data in the HTP / ETP protocols is shared between all communication channels. For this reason it is not possible to communicate at the same time with the RS232 / modem port and the IF2 port using the HTP protocol. If some commands must be issued to the unit using the HTP protocol in the IF2 port, first disable all modem related functions (SMS and emails), otherwise the commands may be not recognized and the modem operations may be disrupted.

ISOMAG

FUNCTIONS OVERVIEW

The ML250 coupled with GPRS/GSM module is capable of the following functions:

• Receive commands from arrived SMS • Answer to commands by sending its own SMS to the network • Send data and events stored in its memory by e-mail, either using scheduled time event or upon received command • Send the complete parameter configuration list by e-mail on demand • Synchronize its internal clock to the timer provided by the configured server

IMPLEMENTED PROTOCOLS

The ML250 recognizes and exchanges data using the following protocols:

• IF2 interface standard protocol to exchange data with a PC or laptop device • DPP (Data Packet Protocol) protocol to exchange data packet data from addressable devices in a network • ETP (Encapsulated Terminal Protocol) protocol to implement HTP protocol over packet data network • HTP (Hyper-Terminal Protocol) Hyper-terminal compatible protocol • SMTP (Simple Mail Transfer Protocol) protocol to exchange data with mail servers • HTTP (Hyper-Text Transfer Protocol) protocol used here to get time and date synchronization from a remote server

OPERATIONS

The System is developed to realize the following basic operations:

• Performs the measure of the flow rate and the pressure or the other measure coming from the external analog input • Integrates the flow rate measure to obtain up to four internal counters for the calculated volumes • Stores and accumulates the flow rate value, the external measure value, two of the four counters and all recognized events • Wakes-up the wireless terminal at preset time and checks for incoming commands contained in SMS • Eventually responds to the commands received by sending the answer in a SMS • Wakes-up periodically and sends the stored data by e-mail to the configured server • After sending the e-mail, checks and adjust the time reading the value from the configured server

Here follows the detailed description of the operations.

• Standby operation: The ML250 is in its “energy saving” mode, sampling the flow rate and the other optional measure at the programmed interval rate (typical every 5 seconds). The ME44 terminal is in its standby mode, detached from the network and thus not capable of receiving anything.

• SMS operation: If the “check SMS” function is set, at the interval specified for this function, the ML250 wakes-up and performs the initialization of the ME44 terminal, ensuring that it is properly attached and registered to the wireless network. After that, it waits for the incoming of new SMS. The time is specified in another parameter and it is configurable. The SMS are checked every 30 seconds, until the complete time is elapsed. If no SMS are received in this time, the terminal and the ML250 return to the standby mode. If one or more SMS are received, the ML250 elaborates the commands and sends the answer to the network using the same SMS support. The system sends an answer for each command that can be correctly interpreted. Commands not recognized are not answered. The event logger of the ML250 records each SMS event, even if the SMS contains no commands or not recognizable ones. For security purpose, a check function can be enabled in the ML250 that verifies the sender ID number of the SMS and accept commands only from that number. The event logger records both the authorized and the not authorized SMS events, but it cannot store the ID numbers of the senders due to the internal memory limitation. Commands contained in a SMS must be in the HTP format.

• E-mail operation: If the “Send Data” function is set, at the interval specified for this function, the ML250 wakes-up and performs the initialization of the ME44 terminal, ensuring that it is properly attached and registered to the wireless network. After that, if the SMS operation are enabled, it waits for a keyboard inactivity until the complete timeout time is elapsed (this permits to receive SMS in this time) and it sends an e-mail containing what the user has specified: static data, dynamic data and events. If the e-mail results is accepted by the SMTP remote server, the data in the selected logger are cleared. If the E-mail send operation has failed, the system retry for other four times at the following time intervals, starting from the first try: 5 minutes, 10 minutes, 30 minutes and one hour. After these tries, the sending session is aborted and re-initialized at the next normal interval.

• Clock synchronization: This function is possible only in conjunction with an e-mail send session. If it is enabled, the ML250 sends the e-mail and contacts the time server specified. The server must be configured in order to supply the time and date values in a string properly formatted (see further description). If this operation ends with positive result, the ML250 clock is adjusted accordingly and the event is recorded in the logger.

• Operations on demand: The delivery of the e-mails containing either the acquired data or the instrument’s configuration can be requested by the control center using SMS commands or by an operator using the front panel of the ML250. For the first case, in order to obtain the answer, it is necessary to wait the time specified for receiving SMS, since the SMS are received only when the system wakes-up. When the system is powered by stable source network or it isn’t in the “energy saving” mode, the SMS are checked every 30 seconds, so it is possible to issue commands more often. A local keyboard operation is always possible, since the instrument wakes-up whenever a key is pressed.

• NOTE: When this command is invoked by the instrument’s keyboard, the operation is carried out only when the unit returns to the process data display and due to some internal initializations.

• Parameters list reception: With this function it is possible to send a set of configuration parameters or commands to the instrument greater than that can be sent via SMS. The command can be invoked by SMS only and consists in a set of parameters used to connect to a HTTP server to retrieve the list. The list size must be less or equal to 1kByte. No answer will be issued to the remote end after reception.

• Software update: With a set of specialized commands it is possible to connect to a HTTP server and to download automatically a new software release. This function is possible only when the data logger is not in use and it does not contain any data. Once invoked, the process is all automated. The new downloaded software is first checked before it is written in the memory. In case of error the process is aborted and the instrument resumes the normal operation. All operations sequence are logged in the event logger.

DATA FORMATS

PROCESS DATA. All data loggers values are in CSV (Comma Separated Values) format, directly loadable into an Excel spreadsheet or viewable with a text editor (like Notepad). There are two possible layout for the data: one with the measure units and the other without them. This possibility is useful when it is necessary to reduce the volume of data sent over the wireless network. The structure for the sampled data with the measure units is the following:

Record number, date, time, plus sign (symbol for positive volume counter), measure unit, value of positive counter, minus sign (symbol for negative volume counter), measure unit, value of negative counter, flow rate measure unit, flow rate value, external channel measure unit, external channel value. The last two fields are present only if the external channel reading is enabled and configured in the hardware. An example of downloaded set of records already imported in an Excel spreadsheet can be the following:

CONFIGURATION LIST. The format used for the list of the parameters value are the following:

Mnemonic name of the parameter, equal sign, value If the value is one of a series of options, it is expressed as follows: numeric value : description Here are a sample configuration list (partial): PDIMV=25 CFFKA=+1.0000 SFREQ=0:AUTO EPDEN=0:OFF EPDGV=1 SZPCC=0 FRMUT=0:VM FRMUV=15:dm3/s FRFS1=5.000 FRFS2=5.000 VTMUT=0:VM VTMUV=3:dm3 VTDPP=3 CH1PV=1.00000 P1SPD=3:38400 P1TME=1:ON IFTME=0:OFF LLANG=0:EN ENSDT=60 TCMDE=0:OFF CUSYT=0:EUR CUCSS= CUDEC=2 CUNCF=1.00000 CUPCF=1.00000 DLOGE=1:ON DLGSI=2:10m DTIME=2005/10/19 23:00:51 The configuration list has deliberately a structure that can be re-load by the ML250 using the Hyper Terminal application or the remote parameters list reception via radio device, so it will be easy to retrieve, modify and reload a complete configuration set. See further description on how to load a configuration into the ML250 via the hyper-terminal application.

E-MAIL. The e-mail messages are constructed in multi-part mime format, with one text part and one or more optional attached files. The encoding scheme is all plaintext, standard UTF-8 character set. The fields are the following:

FROM field, used to identify the sender TO field, used to address the message to the receiver SUBJECT field, with the text “ML250 serial num” Text message, the same as the subject, with the name of the device (“ML 250”) and its unique serial number (Attached file 1) (Attached file 2) (Attached file 3) The naming convention used for the attached files has the following structure, using more parts concatenating together to form the final name:

ISOMAG

Two letters prefix + instrument’s serial number _ year _ month _ day _ hour _ minute _ second . CSV The part following the prefix and the serial number (the date part) is dependent on the layout language chosen for the ML250 (if it is select the English language the format is exactly as illustrated, in the other cases the date part is reversed: day-month-year). The date and time stamps are those at the moment of the creation of the file inside the instrument, so they are unique. The two letters prefix has the following meaning: DD = Dynamic Data, identifies the data coming from the dynamic data logger located in the RAM of the instrument, that samples data at the same frequency of the measure refresh cycle (from 1 second to what is selected as “sampling interval” for the energy saving mode). SD = Static Data, identifies the data coming from the static data logger located in the EEPROM banks of the instrument, that samples data at the rate set by the function “Interval” of the data logger (from 1 minute to 24 hours in 8 steps). EV = Events, identifies the data coming from the event logger of the instrument, sampled whenever a new event condition is detected internally. CF = Configuration data, identifies a list of configuration parameters. Here are some filename examples coming from a ML250 having serial number = 17128 and layout language = English: EV17128_2005_10_20_00_00_34.CSV : events file SD17128_2005_10_20_00_00_28.CSV : static data file CF17128_2005_10_20_09_08_01.CSV : configuration list

TIME SYNCHRONIZATION STRING. The string read by the ML250 via http protocol must be formatted as follows:

DTIME=YYYY/MM/DD hh:mm:ss in case of English layout language and DTIME=DD/MM/YYYY hh:mm:ss in the other cases. DD = day MM = month YYYY = year hh = hours in 24 hours format mm = minutes ss = seconds There are no spaces between the token “DTIME=” and the first number of the date, but there is a space between the last digit of the date and the first digit of the hour part. The separators characters are not checked, thus any valid separator can be used ( “:”, “/”, “,”, and so on). The time values given in the string are checked by their position, so spaces or other extra characters inserted in the string makes the interpretation of the values useless. There are no warning indications, if the string contains no valid time reference or it is not formatted correctly, the time read may be still valid as number, but absolutely meaningless as time reference.
