Modem Logger
The Modem logger is a highly advanced, rugged, low-power,
two channel datalogger, with one channel reading an
external 0-10V sensor and the other channel an external
pulse sensor.
The unit combines a high capacity datalogger with an on-board
GSM/GPRS Quad band modem. The logger runs on a single
D-Cell Lithium battery and is housed in a compact and robust
enclosure for reliable use in the field.
Readings are stored on a local SD card and are transmitted in
engineering units to any FTP site via the GSM/GPRS modem.
Logger settings are easily configured by the user, allowing full
control of settings and alarms, making the device completely
adaptable to site specific changes.
The Logger incorporates an intelligent ‘passive’ to ‘active’ alarm
system with up to six user defined prioritisation thresholds,
reducing battery consumption and overload of needless data.
With high capacity monitoring, automatic data transmission and
active multi layered alarming, the Modem Logger is an efficient,
cost effective solution to meet your monitoring requirements.

System Details
THE MODEM
LOGGER
The Modem Logger is a high capacity two channel datalogger with an
on-board GSM/GPRS Quad band modem. The logger incorporates a
barometric sensor, allowing for barometric pressure compensation and
will work with any M2M (machine2machine) SIM card as it is not locked
to a specific network.
The logger has two sensor input channels; one analogue signal channel
and one pulse sensor channel.
The Modem Logger contains a mini USB connector; the USB interface
will mount both as a Flash Drive (MSC) and a serial COM port (CDC).
When connected to a PC, the Flash Drive will mount as an external hard
drive without the need for a software driver, allowing access to the files
on the micro SD card.
The serial COM port can be mounted on a Windows PC by installing the
driver supplied on the SD card.
The Logger can either be programmed manually using a laptop with
a USB cable, or remotely via the FTP server using an editable settings
file from which reading, logging and uploading parameters are set
and calibration factors and alarms defined.
The alarm system, SMS functions, reading intervals and schedules can
be programmed or changed at any time quickly and efficiently via the
FTP site. The data can then be viewed by anyone at any time; all that
is required is an internet connection and the log on details for the
FTP server.
The multi layered ‘passive’ to ‘active’ alarm system incorporates up to six
user defined prioritisation thresholds. Once setup, the Logger remains in
‘passive’ mode logging at user defined intervals, until any of the pre-set
alarm levels are breached, at which point it will automatically switch to
‘active’ mode and initiate increased data logging and transfer to the
FTP site whilst simultaneously sending out multi-level SMS text alerts
to multiple contacts.
The readings are automatically transferred to the FTP site in engineering
units, so data can be directly imported into ‘ARGUS’ Monitoring Software.

that you want to be added or changed; it does not need to be a full
‘settings.ini’ file.
The settings will be retrieved by the logger during the next connection
to the FTP site. An acknowledgement file with the extension ‘.ack’ will
be placed on the FTP server from the device to confirm that the settings
have been updated. Please refer to ‘Part II – Detailed Tilt Logger’ user
Guide in this manual for more details.
The new file for the FTP site, must have ‘.new’ extension as the logger
will download this file and replace it on the SD card as a ‘.ini’ file.

PERFORMING CALCULATIONS ON A CHANNEL
The following describes the functions required for performing calculations
on a sensor channel.
‘calc=<calc string>’ Calculation string performed on sensor value in order of declaration. Operations are declared separated by comma’s (e.g. *8,-0.1,^1). Max total string length is
63 characters.
Available operators are defined in the following table;
OPERATOR
FUNCTION
‘+’
Add
‘-’
Subtract
‘*’
Multiply
‘/’
Divide
‘^’
Power
‘=’
Set equal to
‘b’
Barometer value
‘c<n>’
Value of channel <n>
‘sin, cos, tan’
Sine, cosine, tangent. Input values in degrees
‘asin, acos, atan’
Reverse sine, cosine, tangent. Output values in degrees
‘log’
Natural logarithm (base e)
‘log10’
Standard logarithm (base 10)
‘sqrt’
Square root
‘pcalc’
2nd order polynomial (abc-equation)
To include a second order polynomial calibration function (typical for
piezometers) you will need set the following parameters;
‘[channel_1]piezocalc=a:b:c’ declare the a-b-c calibration constants (for piezometer)
‘[channel_1]calc=pcalc’
calculation is: c + (b x input value) + (a x (input value²))
pcalc in the calc string can still be preceded or followed by other operations.
34
Example 1;
‘[channel_1]calc=/10,+0.003,*1000’
=((value/10)=0.0030*1000
Example 2;
‘[channel_1]calc=pcalc,-1.2’
=(piezocalc)-1.2
When declaring a calc string, the result of the calculation
replaces the sensor output signal (in V) for all other operations;
logging, checking against alarm thresholds and checking against
validation limits.
WARNING
SETTING ALARMS Mulit-layered alarms and SMS text functions can be setup on each channel
ON A CHANNEL
according to your requirements. These are explained in the following
diagram and table;
All settings are preceded by ‘[channel_n]’ for the channel to which
the alarming applies. For example ‘[channel_1]l_limit1=-8.5’.

UPDATING SETTINGS VIA FTP
The following table outlines how to update the Modem Logger settings
remotely via FTP;
STEP
1
2
3
ACTION
Type any settings that need to be added or changed into a file
with the name ‘<unitname>-settings.new.’ the syntax is identical
to the ‘settings.ini’ file; there is no need to include settings that
remain unchanged.
Place the ‘<unitname>-settings.new.’ file on the FTP server in the
folder to which the Modem Logger unit connects. This is the root
directory by default, unless otherwise defined in the Loggers [FTP]
path setting.
During the next FTP session, the Logger will retrieve the
‘<unitname>-settings.new.’ file and merge it with the ‘settings.ini’
file on the SD card, after which the settings will be loaded into the
loggers memory and start operating according to the changes made.
• The setting ‘[FTP]getsettings’ is by default set to 1, even if
not declared in the ‘settings.ini’ file. This allows the updating
of settings via the FTP server, as described above. If you want
to prevent settings being updated remotely, you need to
declare ‘[FTP]getsettings=0’ in the ‘settings.ini’ file.
TIP
If you change the ‘settings.ini’ file to prevent remote updates, any
future changes to settings, including firmware updates will require
a field visit.
WARNING
37
If this function is selected it will increase your data traffic.
WARNING
• Including the line ‘[FTP]sendsettings=1’ in the ‘settings.ini’ file will
trigger the posting back of the complete updated ‘settings.ini’ file
from the SD card to the FTP server every time it connects.
This allows you to check all of the current updated settings.
TIP
METHODS OF UPDATING FIRMWARE
There are three methods available for updating the firmware for the
Modem Logger, two locally using a USB connection to a PC and one
remotely via FTP;
• Copy the file ‘firmware.upd’ onto the SD card using the
USB connection. Perform the command ‘reset’ via the
COM port command line. Remove the USB connector,
then re-insert once the update is complete.
• Copy the file ‘firmware.upd’ onto the SD card using a PC
card reader. Insert the SD card into the Modem Logger,
then power on the unit.
• Add the line ‘[FTP]getfirmware=1’ to ‘settings.ini’ . Make sure
that the new settings file is read; perform the ‘readsettings’
command if necessary. Rename the ‘firmware.upd’ file to
‘<unitname>-firmware.upd’ and place on the FTP server.
The logger will retrieve and install the firmware upon the
next FTP session.
While the firmware update is loading onto the logger, the green
LED will show a series of three short blinks until complete.
IMPORTANT
INFORMATION
When the logger is reconnected via the COM port, you can
check if the firmware has been successfully uploaded using
the ‘ver?’ command.
TIP
38
COMMANDS
VIA SMS TEXT
Commands issued via SMS will be received and handled upon the
loggers next scheduled GSM connection, which is usually the next
FTP transmission session.
SMS TEXT COMMAND
‘[group]field=parameter’
FUNCTION
Changes a specific setting, the syntax is identical to the
‘settings.ini’ file
‘*FTP*’
Force an FTP transmission
‘*status*’
Request all channel values in a reply SMS message
‘*reset*’
Force a full reset of the unit
‘*events*’
Rename the ‘events.txt’ file to ‘<unitname>-events.log’
and force a transmission via FTP
You can use multiple commands in a single SMS message by using a
semi colon (;) as a separator, for example;
‘[main]debug=1;*events*;*status*’
USING THE MODEM LOGGER AS A LOCAL LOGGER ONLY
You can use the Modem logger as a local data acquisition and storage
device only, without data transmission and remote management
through the GSM modem and without the need to install a SIM card.
To use the logger in this mode you will need to implement the following;
• Delete all the settings for the groups ‘[gsm]’ and ‘[FTP]’ in
the ‘settings.ini’ file
• Delete all channel alarm settings that are related to initiating
any FTP and SMS transmission in the ‘settings.ini’ file
• Change the default time of the logger ‘01-01-2010 00:00’
through the line command on the COM port;
‘time dd-mm-yyyy hh:mm:ss’.
Please refer to ‘Part III – Modem Logger Configuration and Data
Files - Available Line Commands - time <date/time>’ for more details.
WARNING
The default start-up time of the logger is ‘01-01-2010 00:00’.
Measurements and data logging will only start after the date
and time have been updated. Usually this is done automatically
at power-on by synching with an external internet time server
during the first GSM connection event. When using the unit as
a local logger this needs to be done manually through the line
command on the COM port.

Appendix B – Frequently Asked Questions
Do I need a static IP (internet provider) address to
operate the Modem Logger?
No, the Modem Logger connects to the FTP directory using a SIM
card (supplied by you). All communications with the web portal are
initialised by the Modem Logger; as a result no static IP is required.
QUESTION
What size of data plan will I need with my SIM card?
The size of data plan you need will depend on how often you are
reading the sensors and uploading the data. Soil Instruments would
suggest a 5MB data plan is more than sufficient for logging two
sensors plus battery voltage, every 10 minutes and uploading data
every day, allowing for some configuration changes throughout
the month (although logging and uploading rates can reduce or
increase the battery life).
Why doesn’t the logger mount as a COM Port?
Check that the ‘TinySense_V2.inf’ driver has been installed and the
COM Port is visible in ‘Device Manager’. If the device is connected,
the green LED will start blinking at regular intervals; 3 seconds off,
1 second on.
Why can’t I communicate with the unit?
Make sure the batteries have been installed with the correct polarity.
Why is my 0-10V sensor not working correctly?
Check the connections to the sensor. Using a Multimeter, check
the excitation voltage to the sensor between ‘E’ (excitation) and ‘G’
(ground). Using a Multimeter, check the voltage between ‘S’ (signal)
and ‘G’ (ground).
Why is my pulse sensor not working correctly?
Check the pulse from the sensor by using the Ω / Ω function
on your Multimeter. Move the sensor to generate the pulse.
As the contacts come together, the resistance on the Multimeter
will go from -1 to 0 and a an audio buzz will be heard (if the
option is available on your Multimeter).
