1. Introduction
These instructions describe the SMS / GPRS monitoring well modem. This modem is very easy to use. Following a
short description of the functionality, we will address what needs to be taken into consideration when starting to
use the device, we will then address the possible applications and troubleshooting.

1.1 Functionality
In the main, the operation of the monitoring well modem consists of ensuring that data is transported by SMS or email (GPRS) from sensors in the field to a central receiver station.
We can divide the configuration into three components; See figure above.
1) e-SENSE direct, the home base
2) configuration options, monitoring well modem configuration tool
3) e+ sensor / Diver® by Schlumberger Water Services / analogue sensor (optional) / internal barometric sensor
(optional)
Please download the software monitoring well modem configuration tool before
you start. The software can be downloaded from: www.eijkelkamp.com at Products
/ Software.
Functionality of internal baro sensor
If the internal (baro) compensation option is activated, the modem will only send compensated data. The raw baro
sensor data and the connected logger data is then not available. Raw data is still available when the internal (baro)
compensation option is switched off. The temperature data is still available in both cases, provided that the
temperature sensor is activated.
1.2 Applications
The use of the monitoring well modem has several practical advantages. In the first place, the use of GSM
communication provides the means to take measurements and send them using a wireless connection from any
conceivable location. This means that the system can be used at locations where there is no electricity or telephone
network available.
Furthermore, it is unnecessary for a person to read out the (measuring) data from the sensor in the field, as the
monitoring well modem is tasked with reading the data and sending them.
Because these data are sent to the central receiver station completely independently, the system is more or less
maintenance free. It is unnecessary for a person to regularly inspect the condition of the sensors or to read out the
measuring values in the field using a laptop. After the sensors and monitoring well modem have been installed, the
only activity required in the field is to replace the battery(ies) of the monitoring well modem and the connected
sensor.

2. Getting started
This chapter explains how you can immediately start to use the monitoring well modem.
Please download the software e-SENSE monitoring well modem configuration tool
before you start. The software can be downloaded from: www.eijkelkamp.com at
Products / Software.
2.1 General
The monitoring well modem can be connected to various types of sensor; the e+ sensors, the Divers and the sensors
with an analogueue output (4 .. 20 mA or 0 .. 5 Vdc). The measuring data are sent by SMS or e-mail to a central
server where they are processed. It is possible to remotely configure the monitoring well modem using the central eSENSE direct server (SMS or e-mail) or locally using a connected laptop running the monitoring well modem
configuration tool (hereinafter called the configuration tool) or via standard e-mail programs (text). The monitoring
well modem is equipped with two status LEDs (operating status), a service key and IrDA communication.
2.2 Connection and provisions
The monitoring well modem has one connector at the bottom of the housing. In addition, at the top there is a
panel with a service key, IrDA, LED indicators and an aerial. The monitoring well modem is (optional) equipped with
its own internal barometer and temperature sensor, both can be logged using the log function.

2.2.1 The connector
The connector is a 5-pole, waterproof, M12 connector. The figure below shows how to connect an e+ sensor (CTD
Diver).
2.2.1.1 Monitoring well modem analogue input
The monitoring well modem is provided with an analogue input. This analogue input is able to measure current (0
to 20 mA) or voltage (0 – 5 Volt). The input comprises a mass, port and activation pin. As the monitoring well
modem is not active all the time, the activation pin will be activated 10 seconds before the analogue measurement
becomes active, so that any external meter can enter the value through the analogue input.
The analogue input behaves like a virtual e+ logger. The software can be used to set the value to any desired
parameter, for example m3/h. Just as with an e+ sensor, alarm reports can be generated.
- The standard configuration of the input is for 0-20 mA.
- The analogue sensor connected must have its own power source.
- On activation, the activation pin switches to mass (open-collector).
The connections to the M12 logger-connector on the underside are defined as follows:

(2-wire interface)
(0...20 mA or 0...5 volt)
(open collector by mass)
Standard adaptor cable item number: 11.31.15.02.01
For reasons of compatibility, pins 1 and 3 are used for the 2-wire interface.
Pins 2, 4 and 5 on the monitoring well modem are used for the analogue
input (software can be set to 0 ... 20 mA or 0 ... 5 volt).
Pin 4 (red) is the current or voltage input
Pin 2 (black) depends on mass
Pin 5 (white) is an open-collector input that is switched to mass when the
external analogue sensor begins metering.
If an external logger is connected, the analogue input runs in time with the
external logger. If no external logger is connected, the analogue input runs in
time with the internal baro. If there is no active internal baro either, the
analogue input can be set.

2.2.2 Installing the top cap
Before the top cap is placed in the modem housing, the O-rings must be installed and greased with Vaseline.
Place the 2 O-rings in the spaces.
Grease the O-rings with Vaseline and slide the cap
in the housing.
2.2.3 The aerial
The modem can be equipped with a ‘whip aerial’ or an ‘external aerial’. The whip aerial must be installed in the
following way.
Apply a layer of Vaseline to the O-ring of the
connector.
Holding the nut, screw the aerial into the top socket
until it is ‘hand tight’. Then tighten the aerial a
further half turn using a 13 mm open-ended or
ring spanner.
7
The ‘external aerial’ is installed in the same way as above.
Apply a layer of Vaseline to the O-ring of the
connector.
Screw in the connector with the nut ‘hand tight’ in
the top socket. Then tighten the aerial a further
half turn using a 13mm open-ended spanner.
2.2.4 The panel
The panel has one service key indicated by the ‘spanner’, two status LEDs (red and green) on the left-hand side and
an IrDA interface on the right-hand side. The aerial is in the middle.
First start
When the service key is pressed for five seconds and the monitoring well modem is already configured, the
monitoring well modem will log on to the central receiver station (when logging on, both LEDS are active).
If the monitoring well modem is not configured, the red LED will flash. Press the service key, for 15 seconds, until
the monitoring well modem enters the configuration mode. The red LED will light. In the configuration mode, the
IrDa interface is active for communication with the configuration tool.
Operating
When the service key is pressed for five seconds, the monitoring well modem enters the status mode and one of
the two LEDs flashes to show the status.
Configuration mode
When the service key is pressed for 15 seconds, the monitoring well modem enters the configuration mode and one
of the two LEDs will be lit (dependent on the error condition). In the configuration mode, the IrDa interface is active
for communication with the configuration tool.
When setting the well monitoring modem to configuration mode, all processes active
in the modem at the time are shut down appropriately.
If after 15 seconds the red or green LED is not on continuously, release the service
key and press once more for 15 seconds. Do this until one of the two LEDs is on.

The configuration mode must be exited by pressing the service key for one second, or via the configuration tool.
After exiting the configuration mode, the monitoring well modem automatically runs through the log on procedure.
The first 10 seconds the LEDs remain off! Then both LEDS will be active.
When the log on procedure has completed successfully, both LEDs will go out. If not, then the red LED will light
(indicating an error condition) and the monitoring well modem will automatically enter the configuration mode.
If the red LED is on continuously: The monitoring well modem will turn itself off if it
has been in configuration mode for 10 minutes and there has been no activity. The
log on procedure will then not be performed. Any changes made will be saved. The
monitoring well modem can be activated again by pressing the service key for 5
seconds.

If the green LED is on continuously: The monitoring well modem will turn itself off if
it has been in configuration mode for 10 minutes and there has been no activity. The
log on procedure will then proceed. Any changes made will be saved.

2.3 Preparing for use
Monitoring well modems may be configured by Eijkelkamp, but can also be configured by the end user with the aid
of the configuration tool software. Configuration includes:
 Communications settings such as dial-up numbers, GPRS settings and internet gateway etc.
 Time intervals such as activation interval and send interval
 Configuration of function of the built-in barometer (internal baro for Diver compensation)
 Max. number of text messages per channel
 Configuration of e-mail, e-mail server
Before starting the installation:
 The sensor in use must be stopped and must contain no data (not strictly necessary, but certainly preferable,
because these data will be send when logging on).
 The sensor in use must be connected to the monitoring well modem.
 The sensor in use must be configured. This can be done using the configuration tool (tab sensors. See below for
possible settings).
 The first time to send the SMS (or e-mail) and the interval between sending SMSs (or e-mails) must be
determined (tab sensors of the configuration tool).
 e-SENSE direct must be installed on the PC or on the central server and brought into operation, if text messages
are used (see instructions for use for e-SENSE direct).
There is a distinction between user settings and configuration parameters. Configuration parameters can only be set
by Eijkelkamp, these include a ‘firmware’ update, serial number and the first dial-up number. This also applies for
the commercial options including: the internal barometer, redundancy, e-mail, etc.

Default = Eijkelkamp Giesbeek. This field is used to indicate where the
modem is located.
Default = 51.98879, 6.055444. This field can be used for the GPS
coordinates of the modem.
Standard is 120 minutes. 12 time per day the modem will become active to
check if any update messages have been received.
Default = 0. When the temperature is below this value the modem will not
make a connection with the GSM-network; this will save the battery.
Default = 5. The number of wake-up intervals that may be waited before
sending at the set temperature threshold. After the number of wake-up
intervals has expired, the modem will send the data.
Default = Active. The monitoring well modem's internal clock will be
synchronised with the central server's clock
Default = 120 days. Every 120 days the monitoring well modem will be
synchronised with the central server's clock.
In case of e-mail these servers will be used to synchronise the RTC
Default = 1. Can be set only local or by e-mail. Only when e-mail is selected
Default = de-activated. Can be set only local or by e-mail.
Default = 20 %. The value at which a low battery alarm is generated.
Default = 0. Three options are possible here: 0, 1 and 2. For option 0, only
the current measuring data are sent, for option 1 the measuring data of the
current and the previous send interval are sent, for option 2 the measuring
data for the current and the previous two send intervals are sent.
Default = 25. This is the maximum number of SMSs that may be sent per
send interval per channel.
Default = Dial-up numbers. These are the telephone numbers of the servers
to which the measurement values will be sent. In the case of e-mail the text
warnings will be sent to these numbers.
Default = MON. In the case of e-mail one can choose for MON or CSV
format.
Default = de-activated. It is possible to export the data of the internal baro in
MON format. MiniDiver is set as type of Diver. It is than possible to read the
data in Diver Office.
Default = activated. Readings from two-eye Divers (old type number <12) are
converted to one-eye Diver (newer type) readings, so that they can be used in
Diver Office.
Default = activated. It is possible to add a header to the CSV file with
information on the sensor.
Default = de-activated. If this option is de-activated minimum measurement
values will be filled out for de-activated channels.
Default = de-activated. In a CSV file the columns are separated by a special
sign. It is possible to choose between dot-comma or ‘TAB’ separated.
Default = activated. It is possible to choose for the CSV file between comma
and point.
Default = value in sensor. This field is used to describe the location of the
sensor.
Default = 08:00. The time at which the monitoring well modem will send the
log messages.
Default = 1440 min. Send SMSs once per day.
Default = 60 min. Log/ record measurement values once per hour.
Default = all channels activated. An activated channel sends measurement
values, a deactivated channel does not.
Only for 2-eye Divers with a type number <12
Displacement of zero-point sensor for channel 1
Alarm threshold value, default = maximum range
Alarm threshold value, default = minimum range
Default = maximum range

Average measurement
Internal compensation

Default = de-activated. Average measurement means that multiple
measurements will be taken in a minimum of two minutes. The average of
these measurements will be saved and/ or sent.
This is only applicable for suitable e+ sensors, not for Divers.
Default = de-activated. The modem itself can execute barometric
compensation and therefore can generate alarms on the base of
compensated measurement values.
The most practical approach is, before going into the field, to first configure the
monitoring well modem and then to start it up once and let it log on to the central receiver
station on which e-SENSE direct is installed.

Contact your provider and make an agreement on protection concerning max. SMS per
month.

Eijkelkamp Agrisearch Equipment is not responsible for high costs caused by configuration
errors.
2.4 Configuration
Before going into the field, the monitoring well modem must be configured. This can be done using the
configuration tool (software).
Press the service key for 15 seconds to enter the configuration mode. Now use the configuration tool, connect the
e+ infrared communicator to, for instance, your laptop. The communicator must be held within a distance of 1 m
from the monitoring well modem. Read out the current configuration and amend it where required.
If after 15 seconds, neither the red nor the green LED is on continuously, release the
service key briefly and press once more for 15 seconds.
Do this until one of the two LEDs is on.

Tip:
After the modem has been set, it is advisable to create a screen capture of all the tabs and to save them with
the project data. This allows the basic settings to be seen at a glance.
2.4.1 All tabs
These buttons are present on all tabs:
The Reload info button is used to refresh only the information on this ‘status’ tab.
The Prepare modem for installation button is used to turn off the modem. As soon as the modem is installed in
the field, it can be started by pressing the service key for five seconds.

Prepare modem for installation can only be used if both the modem and the connected
sensor are configured together in the office.
The Save all changed settings and close the modem button is used if no logger is connected to the monitoring
well modem. After pressing the service key, the monitoring well modem will immediately enter the configuration
mode.
Using the Save all changed settings and restart the modem button causes the monitoring well modem to exit
the configuration mode and log on with the new settings.
13
2.4.2 Status Tab
In the Status tab we can see the status of the system at a glance:
 Modem Status: (status of the monitoring well modem)
 SNR: … dBM (signal quality).
 SMS-ses send … (the number of SMSs send up to now).
 Battery capacity … (The current battery capacity).
 Alarm battery capacity …. (The entered percentage at which a battery ‘low’ alarm SMS must be sent).
 Serial number … (the monitoring well modem serial number).
 Current date/time …. (The current internal date and time).
 Hardware version … (Hardware version of the monitoring well modem).
 Software version … (installed Firmware software version in the monitoring well modem).
 Logger information: (serial number + the last logged measuring values of the connected logger).

In this tab no changes are possible!
The About… button is used to give information on the software used (version, copyright, etc.)
The Reload all info button is used to refresh all the information on all tabs.
14
2.4.2 Modem Tab
In the Modem tab, the various settings of the monitoring well modem can be changed:
 Location (the location of this monitoring well modem).
 GPS coordinates (GPS coordinates of this location).
 Wake-up interval … minutes (Every … minutes the monitoring well modem wakes up to check whether update
messages have been sent by e-SENSE direct. Minimum 5 minutes).
 Enable daytime saving (By ticking this option, the monitoring well modem will automatically adjust its internal
clock at the transition between summer and winter time and winter and summer time. This does not result in
the clock being synchronised with the e-SENSE direct server, the monitoring well modem however will send all
data gathered till this transition)
 Synchronise date/ time with the server, every … days (Tick and set the number of days after which the
monitoring well modem will synchronise its internal clock with the e-SENSE direct server).
 Data redundancy … (Optional. Three options are possible here: 0, 1 and 2. For option 0, only the current
measuring data are sent, for option 1 the measuring data of the current and the previous send interval are sent,
for option 2 the measuring data for the current and the previous two send intervals are sent).
 Battery capacity alarm (The entered percentage at which a battery ‘low’ alarm SMS must be sent).
 Current battery capacity (Current battery capacity, field cannot be changed).
 The New battery button resets the battery capacity measurement after a new battery has been installed.
 Do not send below … degrees Celcius (The set temperature threshold under which the modem must no longer
send messages due to the limited battery capacity at low temperatures).
 Wait max. … wake-up intervals (The number of wake-up intervals that may be waited before sending at the
set temperature threshold. After the number of wake-up intervals has expired, the modem can send the data).
 SIM PIN (If the SIM card is protected with a PIN code, enter the PIN code here)

Current battery capacity, Serial number, Current date/ time, Hardware and software
version cannot be changed!
15
2.4.4 Sensors Tab
In the Sensors tab, the settings of the connected and activated (internal) sensors can be viewed and updated. We
will explain the most important settings on this tab. For the remaining sensor-related settings, we refer to the
manuals of the e+ sensor or Diver concerned.
 Measuring interval … minutes (is the measuring frequency of the logger, every … minutes a measurement is
taken and saved)
 Send interval … minutes (is the sending frequency of the monitoring well modem. Every …. minutes the
measuring data are sent. Note: The Send interval must always be a multiple of the Wake-up interval and a
minimum of 15 minutes. See the modem tab !)
 Send start (hh:mm) ) (The combination of send start and send interval determines when data is sent).

If ‘Average measurement’ is activated, then the measuring interval must be a minimum
of two minutes!
Note: Average measurement means that 10 measurements are taken during the measuring interval. The average of
these measurements is stored and/or send. Always 10 measurements per measuring interval!
The measuring and send intervals of the internal baro sensor are equal to the measuring
and send intervals of an external sensor.


If an external e+ sensor or Diver is connected it is not possible to set the measuring and
send interval of the internal barometer and analogue port.

When only an external analogue sensor and internal barometer are used, only the
measuring and send interval of the internal barometer can be set
16
Location (sensor site)
Altitude (height of the two-eye Diver, needed for compensating pressure difference)
Offset (displacement of zero-point sensor for channel 1)
The readings can be read off from the selected sensor with the Download sensordata button. The readings are
not deleted.
Calibrate internal barometer button is only active if the option Internal compensation is ticked.
With this button, the offset of the internal baro with respect to the Diver in the air is determined. In this way the
absolute deviation in the reading from both the internal baro sensor and from the Diver is eliminated.
Fluctuation alarm: the fluctuation alarm is active for all loggers on all channels, with the exception of Diver channel
1. Here the modem can only generate fluctuation alarms for internally compensated Divers.
(applies to all e+sensors, internal baro, analogue port and internally compensated Divers)
The Reload info button is used to refresh the information in this modem tab.
The Send to sensor button is used to update the settings in the sensor. After a restart of the monitoring well
modem, the settings will be definitively updated.

The logger is restarted after the monitoring well modem has successfully logged on to
e-SENSE direct, the home base (R(eal)T(ime)C(lock)-synchronisation) and / or after
10,000 readings. (Readings sent to e-SENSE direct)
17
2.4.5 Settings tab
The settings of the e+ infrared communicator can be seen and can be updated in the Settings tab. The language of
the configuration tool can also be set in this tab. Below we briefly explain the various settings;
 COM-port (Provides the opportunity to choose the PC communication port to which the e+ infrared
communicator is connected on the PC. Also when using an RS232 – USB convertor cable).
 Select language (this is used to set the language of the configuration tool. Either Dutch or English can be
selected.
 Download sensor data settings
 Company: the name that is filled in in the MON file when reading off the logger via the modem locally.
 Export internal barometer as Baro Diver: tick when reading off from the internal baro, so that the internal baro
is regarded as a Baro Diver when creating a MON file. The data can then be read in Diver Office.
 Convert to absolute: when this option is ticked, readings from two-eye Divers are converted to one-eye Diver
readings, so that they can be used in Diver Office.
The Load default settings file button makes it possible to reset the monitoring well modem to the factory
settings. It resets amongst others: serial number, destination numbers and wake-up interval.
The Default settings file is monitoring well modem dependent and is available from Eijkelkamp
Using the Create service file button, all settings are captured in a text file. Eijkelkamp is able to use this file for
service purposes.

2.5 Switching on
As standard, a monitoring well modem is non active, even after the battery has been replaced.
After connecting the battery, the internal modem software must be launched by pressing the service key for 5
seconds. Depending on a number of factors, the modem will:
- launch configuration mode immediately
- indicate its status by means of a flashing LED. Press the service key until the modem enters configuration mode
(one of the two LEDs is on).
- launch the log on procedure.
If the modem is in configuration mode, the following situations can arise:
If the green LED is on continuously, the log on procedure can be launched by pressing the service key until the LED
goes out.
If the red LED is on, the error must be corrected before the log on procedure can be launched. Once the log on
procedure has successfully been completed, both LEDs will go out.

2.6 Installation
After the previous preparations have been completed, the monitoring well modem can be installed in the field. We
distinguish two installation methods, namely;
 Directly in the monitoring well or
 In a monitoring well that is installed in a ‘protective cylinder’
As standard, the modem is fitted with a fixed whip aerial, but an external aerial is also available. The external aerial
is intended to be installed on the cover of the protective cylinder.
Adjust the universal monitoring well adapter ring to your monitoring well so that the modem hangs correctly in the
monitoring well. Then connect the sensor cable to the monitoring well modem. Allow the monitoring well modem
to drop into the monitoring well.

2.7 Alarm system
It is possible to generate alarms if there are compensated measurement data available. This can preferably be
arranged via the internal barometer (when internal compensation is active) in the monitoring well modem.
monitoring well modem with internal barometer: at every measurement interval (standard value: 1 hour) an alarm
can be sent (of course only if the alarm level has been reached or exceeded)..
SMS: Alarms are always indicated via e-SENSE direct. e-SENSE direct sends the alarm message straight through to
the GSM number (alarm number), that has been entered into e-SENSE direct (see instructions for use e-SENSE
direct).
E-mail: Modem sends an e-mail with data to the configured e-mail addresses. If dial-up numbers are configured,
the modem will sent a text message to all the telephone numbers. No back-up office is needed to sent SMS
messages.
Via e-SENSE direct: as soon as the measurement data of the external barometer and the related data from the
modem have been received, an alarm can be sent.
Therefore:
 e+ sensor (e.g. e+ WATER L): compensated data: if the alarm value is exceeded, a signal is sent to the modem
and an alarm is given (e+ sensor operates synchronously with the modem, therefore the alarm is immediate).
 Diver with internal barometer and internal compensation active (via monitoring well modem): if the alarm value
is exceeded, a signal is sent to the modem and an alarm is raised (Diver with internal barometer operates
synchronously with the modem, therefore the alarm is immediate).
 Diver with (external) Baro Diver (or internal barometer with internal compensation not active): only when data
from the Diver and Baro Diver have been received, can e-SENSE direct transmit an alarm. It is possible for this to
take (up to) 24 hours.

3. SMS functionality
3.1 SMS tab
The various SMS settings can be set and changed in the SMS tab.
 Send max. … SMS-ses per channel per send interval (The maximum number of SMSs that may be send per send
interval per channel).
 Dial-up number 1/2/3/4: … (dial-up number / dial-up numbers for e-SENSE direct) Dial-up number 1 cannot be
changed but is configured by Eijkelkamp, the remaining three can be freely configured. A minimum of one dialup number must be filled in.

Dial-up number 1 cannot be changed!
The Reload info button is used to refresh the information in this modem tab.
The Send to modem button is used to send the changes to the monitoring well modem. Note: the new settings
are only accepted after Save all changed settings and restart the modem button has been clicked.

Questions and answers
3.2.1 During the installation
The following tips give more information about how to act if an error condition occurs during the installation. Based
on the status LEDs on the panel and the configuration tool, you can determine what the problem is and correct it.
Question / problem:
The status LED does not light after five seconds when I press the service key.
Possible solution / answer:
Press the service key for five seconds again or keep it pressed for 15 seconds to enter the configuration mode. If still
nothing happens, try to use a laptop running the configuration tool to make contact with the monitoring well
modem. If it is still impossible to make contact, the monitoring well modem must be removed from the monitoring
well. Disconnect the battery, wait at least 10 seconds, reconnect the battery and try again to make contact with the
monitoring well modem. Contact Eijkelkamp, if disconnecting the battery does not help.
3.2.2 During use
If the installation and the start up of the monitoring well modem are successfully completed, it is possible that an
error could occur some time. Based on the following tips and instructions, you can try to determine what the
possible error is and how to correct it.
Question / problem:
The monitoring well modem always functioned well, but the measuring values are received at the central database
with increasingly more interruptions.
Possible solution / answer:
The GSM signal is possibly too weak. Check the GSM signal strength on site using the configuration tool. The signal
strength must be a minimum of -95 dBm. If the measured signal strength is too low (between -95 dBm and -113
dBm) then probably the variations in the signal strength are the reason that the SMS messages are not received by
the central server. A possible option is to install the monitoring well modem in a protective cylinder with an external
aerial. In the most extreme cases, a new location must be found for the monitoring well modem.
If the external temperature drops below the‘ Do not send below … degrees Centigrade’ setting, then the modem
waits before sending the messages until the outside temperature has risen sufficiently or the maximum number of
Wake-up intervals has passed.
Question / problem:
After the monitoring well modem has operated correctly for some time, suddenly, no new measuring values are
received for a certain sensor.
Possible solution / answer:
It is possible that the monitoring well modem's GSM connection is temporarily unavailable. The measuring values
will then be re-sent later. If the error does not go away, it is possible that the sensor cable has been damaged, the
sensor's battery is flat or the sensor has developed an error. In that case, an alarm message is sent. As soon as the
communication is restored the modem will sent data again. Check the sensor in the field using the configuration
tool and if possible replace its battery (this is not possible for a Diver®). Contact Eijkelkamp if the sensor is broken
or the error cannot be corrected.
Question / problem:
How can I turn off the monitoring well modem?
Possible solution / answer:
The monitoring well modem is turned off as follows; set the monitoring well modem in configuration mode and
disconnect the battery.
23
Question / problem:
The monitoring well modem operates well, but after some time the measuring values do not correspond to the
correct times.
Possible solution / answer:
During a monitoring well modem re-start, both the clock of the internal monitoring well modem and the internal
clock of the connected logger will be synchronised with e-SENSE direct. The monitoring well modem can be restarted by putting the monitoring well modem into configuration mode (press the service key for 15 seconds until
the green LED lights) and then pressing the service key again to leave the configuration mode. After leaving the
configuration mode, the monitoring well modem saves its settings which takes ten seconds. During this period,
both LEDS are off. After ten seconds, the monitoring well modem starts the log on procedure.
Question / problem:
When re-starting after changing the SIM card, the red LED is lit continually.
Possible solution / answer:
Check whether the dial-up numbers are still correct. Is the PIN code of the SIM card turned off or set to another
value. Check all of the settings of the monitoring well modem. Check whether the SIM card subscription is active. If
the SIM card is a prepaid card, check whether there is still sufficient credit on the card account.
Question / problem:
What is the best time to disconnect the battery?
Possible solution / answer:
When the modem is in configuration mode.
Question / problem:
How many SMSs can be saved in the monitoring well modem if there are problems with reception quality or if the
prepaid credit is exhausted?
Possible solution / answer:
The SMSs will be saved if they cannot be sent within the send interval. The cause can be poor reception, exhausted
prepaid credit, or a provider fault. A maximum of 99 SMSs can be saved in this way. In the case of log messages,
the maximum is 6534 log values.
After the monitoring well modem has saved 6534 log messages, any subsequent messages will be lost. The
monitoring well modem will continue to run and periodically try to send the log messages. The monitoring well
modem starts to send messages automatically when the prepaid credit has been topped up. This is also the case
when the monitoring well modem is moved due to poor reception quality.
Therefore, the measuring data remain intact, but new measurements will no longer be saved.
Question:
When logging in again a modem with connected compensated Diver, the problem rises that non-compensated
data are sent by the modem.
Possible solution / answer:
Instruction to log the modem on with internal compensation.
When the modem follows the log on procedure and it is configured with internal compensation activated the data
it sends will not be compensated.
To minimize loss of data act as follows in the below mentioned situations:
When the modem sends the data via e-mail: delete the attachment of the external logger that is mailed during the
log on procedure or process the data separately.
When the modem sends the data via SMS, the data will not be processed by e-SENSE direct when these data are
received already during prior send intervals. It is however possible that data are received in the database that were
not send yet. These measurements must be ignored because they are not correct.
24
Question:
Configuration mode will not start!?
Possible solution / answer:
Release the service key and press the service key again for 15 seconds. If configuration mode will not launch after
several attempts, disconnect the battery for 10 seconds.
Question:
The modem will not log on!?
Possible solution / answer:
A weak signal could be the cause. Return the modem to configuration mode and check the signal strength several
times (Reload info in the Status tab). If the signal strength (after several readings) is -171 dBm, the link between the
modem and the antenna is cut. Check the connection.
If the signal strength is < -95 dBm, the location chosen is unsuitable or there are provider problems.

Eijkelkamp recommends that prepaid SIM cards should not be used because of the
difficulty in checking the credit and the consequences of the credit being exhausted!

E-mail functionality
Introduction
In the recent past, the best option for sending data from the field to a back office was the Short Message Service
(SMS). Even when the General Packet Radio Service (GPRS) became available, it was not really an option as it was
prohibitively expensive early on. But times have changed. Nowadays, SMS is useful in areas where there is no GPRS
service, e-mail is the new communication standard for this purpose. There are several advantages to using e-mail. If
you choose your contract carefully, the costs are lower than those for SMS, the battery lasts longer and you no
longer need a back office (as you would need e-SENSE direct, for example, if you wanted to send data by SMS).
4.1
An e-mail is sent to the configured e-mail addresses and the data in question is sent as an attachment to the e-mail.
Attachment formats:
 MON Format: These files can be read in from Diver-Office and +software LDM;
 CSV format: Comma-Separated Value files which can be read in in Microsoft Excel.
4.2 Functionality
The required monitoring well modem and logger settings are simply sent to the modem by means of an e-mail. It is
not possible to configure the modem and the connected logger by SMS if you use the e-mail functionality.
Whenever settings in the modem are changed, an e-mail will be sent to the e-mail addresses configured for
outgoing e-mail to confirm this. A maximum of 4 outgoing e-mail addresses can be freely configured.
In the event of an alarm, an alarm e-mail will be sent directly to the e-mail addresses configured for outgoing email.
Other e-mail functionality:
 Storage of the 10 most recent changes received; these can be read out through the e-mail;
 Internal clock synchronisation with an NTP server;
 Password security can be set up.
4.3 E-mail tab
E-mail settings can be configured and altered using the e-mail tab of the modem configuration tool. The individual
settings are explained below:
GPRS settings
 APN (Access Point Name: Access point to the internet);
 User name (of the APN);
 Password (of the APN).
POP3 settings (modem)
 Server (server name);
 Port (default 110);
 User name (of the POP3 server);
 Password (of the POP3 server).
SMTP settings
 Server;
 Port (ditto);
 User name (ditto);
 Password (ditto).
NTP settings
 NTP server 1 through 3 (default: nl.pool.ntp.org);
 GMT offset (is the GMT time correction needed for your region).
Show passwords (Option for making passwords legible when entering them).
E-mail addresses
 Reply address (is the address of the modem sending the e-mail; this does not necessarily have to be the real email address of the modem to which the change requests are sent. For security reasons, the default here is:
[email protected]);
 E-mail addresses 1 through 4 (Outgoing e-mail addresses: Fill in at least 1 e-mail address).
27
Attachment settings
 Use MON format as attachment for settings appendix (the appendix is sent with the e-mail in MON or CSV
format);
 Export the internal barometer as Baro Diver (the data from the internal barometer is interpreted by Diver Office
as e+loggers and will not be accepted. If you tick this option, the data will be accepted by Diver Office);
 Convert to absolute (Readings from two-eye Divers (old type number <12) are converted to one-eye Diver
(newer type) readings, so that they can be used in Diver Office.
CSV settings
 Include header (all the sensor details, such as the serial number, measuring and send intervals are displayed in
the CSV file);
 Hide deactivated channels (Deactivated channels are not displayed in the CSV file);
 Use ‘TAB’ as separating symbol (Default = ; semicolon);
 Use decimal point (Default = , comma).
Select language for alarms (Language choice for standard alarms);
Authentication password (to provide extra security for the e-mail traffic between the modem and the back office).
4.4 Alarms and error messages (e-mail and SMS)
There is communication between the connected logger and the modem at each log interval. In the event of an
alarm or error message an e-mail is sent directly. In the event of an alarm, the alarm in question will be sent with a
‘normal’ status mail including data. In the event of an error message, an error message e-mail will be sent.
Furthermore, it is also possible for the alarm to be sent as readable text or directly by SMS; you must, however,
make sure that the data contract supports SMS functionality. The alarm or error message e-mail is sent to the 4 email addresses configured. The SMS alarm messages are sent to the 4 numbers configured for outgoing calls.
The error message is shown in the subject line of the error message e-mail received. This error message e-mail is
sent once;

4.5 Internal clock
Each modem has an internal RTC (Real Time Clock). This clock has to be set to the actual time. We call this RTC
synchronisation. The RTC synchronisation of a modem with e-mail functionality takes place through the internet
and NTP servers. Up to 3 NTP servers (NTP = Network Time Protocol) can be configured.
4.6 E-mail
In order to look at or change the settings of the modem and/or connected logger, an e-mail is sent to the modem
requesting a change. The modem reads the contents of the e-mail box stated and checks whether the ‘subject’ of
every e-mail consists solely of the serial number of the modem; the subject may, therefore, not begin with RE or
FW, etc. If the serial number is correct, the e-mail is retrieved and processed by the modem. After processing, a
confirmation e-mail is sent back. If the serial number corresponds, but the content of the e-mail does not, the email is automatically removed. If the serial number is not correct, the e-mail is not read and remains in the inbox.
‘Spam’ in the inbox is rejected on the basis of the subject and remains in the inbox. The maximum size of a change
request e-mail is 6 kB; e-mails exceeding 6 kB are not processed and remain in the inbox. A change request e-mail
must be sent as plain text or it will not be handled by the modem.
It is advisable to check the modem e-mail account regularly using an e-mail program or webmail (provided this is
supported) for any incorrect messages and/or spam. These messages will not be removed automatically by the
monitoring well modem modem.
32
4.7 Security
To make the system even more secure, the monitoring well modem checks the e-mail address of the sender. This email address must be configured as one of the 4 e-mail addresses in the monitoring well modem or the message
will be rejected. Password protection can also be set up in the modem. This password must be included in every
configuration change e-mail message and ensures adequate security. The password option can be set up by the
administrator using the configuration tool.
The monitoring well modem will first send an authentification request to e-mailaddress-1, it will repeat this every
wake-up interval until it receives an answer from e-mail address-1 with content ‘password=<password>’.
Only after this the modem will send the normal register e-mail (with data). The authentification e-mail will look like:
Please check if the following settings are correct:
[email protected]
[email protected]
EmailAddress3=
EmailAddress4=
DestinationNumber1=31612345678
DestinationNumber2=
DestinationNumber3=
DestinationNumber4=
When all settings are correct, send an email to the modem with the following text:
Password=<pass>, where <pass> is the set password in the modem.
When the settings are incorrect, correct them with the local configuration tool.

Summary of the security measures:
 The serial number in the subject is checked;
 The e-mail address of the sender is checked;
 The password in the text of the e-mail is checked (optional).
4.8 GPRS settings
The provider used must make the following details available (See Chapter 5.1):
 APN (Access Point Name). Note: there may be a difference between business and private contracts;
 User name;
 Password.
4.9 Getting to work
This paragraph describes how to configure the e-mail in the modem and the home base.
The basic necessities are as follows:
1. e-SENSE monitoring well modem (Article no. 11.31.15) with optional monitoring well modem modem e-mail.
2. SIM card with GPRS contract
a. If the system has to send an alarm by means of SMS to a mobile telephone as well, the SIM card must also
support SMS;
b. The provider details, such as APN (Access Point Name) details and passwords must be requested from the
provider (See point 5 under configuration).
33
3. E-mail account (POP3)
a. E-mail address for the home base;
b. E-mail address for the modem (write down this e-mail address because you will need it to configure the
modem and connected logger through the e-mail program).
3. e+ Infrared communicator (Art. no. 11.31.91) for the local modem configuration tool.
4.10
Configuration
We can split a configuration up into 3 components (see illustration); the settings for each element must be
configured specifically for each client.
 The home base: e-mail program such as Microsoft Outlook, Outlook Express or Thunderbird;
 Configuration possibilities, locally with the e-SENSE configuration tool and from the home base using the e-mail
program;
 e+ sensor/Diver® by Schlumberger Water Services’ /analogue sensor (optional)/Internal barometric sensor
(Optional).

4.10.1 The modem
Ask your e-mail administrator to create an e-mail account for the monitoring well modem modem. It is advisable to
create separate e-mail addresses for the various modems.
The following obligatory e-mail settings must be configured using the modem configuration tool:
Note: The e-mail addresses used in the example are fictitious and have only been used to clarify the procedure.
Note: It is possible that not all user names and passwords are obligatory. This will depend on the provider.
4.10.2 The connected logger
The connected logger (e+sensor or Diver) must be configured prior to use. This can be realised using the modem
configuration tool sensor tab, but also using LDM or, in the case of a Diver, with Diver Office.
Note: All the data present in the logger is sent when the monitoring well modem is registered.
4.10.3 The e-mail receiver
In fact, the e-mail receiver is configured simply by creating an e-mail account to receive the modem status mails and
data.
4.10.4 Starting up/testing
As soon as all the settings have been configured we can start up and test the system.
 Ensure that the receiving e-mail system (PC) is on, is connected to the internet and that the modem e-mail
account is activated.
 Go into the configuration mode of the modem (see the explanation of the status LEDS) and press again, for 1
second on the service button to go through the registration procedure.


You will receive a registration e-mail from the modem with the configured modem and logger settings (and
possibly data).
The modem ‘goes to sleep’ when it receives the RTC setting from the NTP server and no errors have taken
place.
4.10.5 Realising configuration changes using the e-mail program
It is possible to send configuration changes from the e-mail program to the modem:
 Start a new e-mail.
 Adjust the parameters you want to change: change the wake-up interval from 5 minutes to 120 minutes, for
example. Type only the serial number of the modem in the subject line, without adding anything else (in our
case, this is 33000).
 Type the e-mail address of the modem in question in the ‘To’ field, (in our case, [email protected]).
 Select ‘Plain text’ in the message format.
 Press ‘send’ to send the change to the modem.
The change will be accepted at the next wake-up interval and a confirmation e-mail will be sent back.
It is possible to give instructions for more than one change in a Single e-mail. However, make sure that the various
settings do not contradict one another. For example, the send interval is a multiple of the wake-up interval and it
has a duration of at least 15 minutes. A list of the configuration settings usually used is given below.

4.10.6 Questions and answers (FAQ)
Question:
Why doesn’t the modem accept my change?
Possible solution:
Check whether the change request e-mail was correctly drawn up. A change request e-mail has to be drawn up as
follows:
 The correct serial number must be entered in the subject line without any additions such as RE or FW, etc;
 The correct modem e-mail address must be entered in the ‘To’ field;
 The message format must be configured to ‘Plain text’;
 The change request must be drawn up correctly in accordance with the configuration table.
Question:
The system worked for a while but is no longer receiving e-mails and data; what is the problem?
Possible solution:
Has the modem sent a low battery alarm or error message e-mail or SMS? If so, it could simply be a case of the
battery being empty. If not, it is advisable to first send a change request to the modem and wait and see whether a
confirmation e-mail is sent back. If no confirmation e-mail is sent back, you will have to check the modem in the
field to find out why the system is no longer functioning.

5. e-SENSE direct
e-SENSE direct is the central software used to remotely configure the monitoring well modem and where the sent
data is collected and saved. Before the monitoring well modem is started, the e-SENSE direct system must be made
operational. To achieve this, the e-SENSE direct software must be installed on a PC and the PC modem must be
connected to the same PC.
For SMS communication, the e-SENSE direct PC modem must be connected to a ‘free’ serial port. For GPRS (e-mail)
communication, the PC running the e-SENSE direct application must have access to the Internet and the firewall
must be correctly configured for e-mail traffic.
For a detailed explanation, you are referred to the e-SENSE direct software manual.

6. Maintenance
 Regularly check the condition of all connection cables. Inspect the cables for wear or damage and replace
where required.
 Replace the monitoring well modem battery and the e+loggers batteries in time. The minimum life expectancy
of a monitoring well battery is two years in normal use. After a ‘low battery’ alarm SMS has been sent, SMS will
continue to work but only for a limited period.
 Clean the panel of the monitoring well modem before starting to communicate with the laptop and the
configuration tool. This is best done using a clean damp cloth. Do not use acetone, thinner, white spirit or any
other corrosive cleaning agents. These can damage the panel and cause leaks!
 The monitoring well modem does not need servicing, as it is completely autonomous. The settings can be
remotely changed via e-SENSE direct.
 When replacing the battery ALWAYS replace the desiccant bag included as well.
6.1 Replacing the battery
On receipt of a 'low battery' alarm SMS, the battery (art. 11.31.25) must be replaced along with the desiccant bag.
Ensure that the modem is in configuration mode.
We advise you to take the necessary ESD safety measures and to apply new vaseline to the
O-rings in the cap seal of the monitoring well modem during assembly.
Procedure:
1. Open the monitoring well modem by removing the two screws and taking off the cap.
Remove the battery, disconnect the 5-way connector and remove the protective mesh sleeve and the packet of silica
gel.

2. Position the battery booster under the protective mesh sleeve on the monitoring well modem PCB as shown
above.
3. Position the battery booster under the protective mesh sleeve and insert the booster plug and the 5-way
connector in the modem PCB. Put the packet of silica gel back in the protective mesh sleeve, close the modem and
refit the screws.
4. Now start up the modem by pressing the service button and holding it until the green LED emits a steady light.
You will need to press the button for about 20 seconds.
You can now establish a data link with the monitoring well modem (modem) using the ‘e-SENSE monitoring well
modem Configuration Tool’ and the IrDa dongle.
42
5. Connect the IrDa dongle to your computer’s USB port and place it in front of modem’s IR port.
The modem’s IR port is located on the front panel of the device.
Go to the “Settings” TAB and select the COM port that is currently in use.
TIP:
If you do not know which COM port is currently being used, remove the IrDa dongle from your computer’s
USB port, press “Update COM-ports” and check the list of COM ports. Reinsert the IrDa dongle in the USB
port and press “Update COM-ports” a second time. Recheck the list of COM ports: the new port that has
been added to this list is the correct COM port.
6. Go to the “Status” TAB and press “Reload all info” to check whether there is a data link.
If the program starts loading data after you press this button, you have successfully established a data link.
43
7. Go to the “Modem” TAB and press “New battery” to reset the counter. Then press “Save all upoaded settings
and restart modem”.
After it has restarted, the modem will connect to the network. During this process, two LEDs will keep blinking on
the modem. These LEDs will turn off once the device has successfully connected. This may take a few minutes.

Replace desiccant bag
There is a desiccant bag on the printed circuit board on the side of the SIM card. The bag is located between the
printed circuit and a stocking. The desiccant bag should be replaced in the manner described below:
- Work cleanly, anti-statically and in a dry environment.
- Remove the desiccant bag from its packaging at the last possible moment and avoid
contact with damp!
- Carry out the steps set out below with the necessary care to ensure that the printed
circuit board is not damaged.
NEVER REMOVE THE STOCKING FROM THE PRINTED CIRCUIT BOARD!
Step 5: Steps for replacing the desiccant bag.
a) Carefully fold the stocking back sufficiently to expose half the length (see left photo).
b) Remove the old desiccant bag carefully (see right photo) and check whether this bag is excessively
wet. If this is the case, this could be an indication of leakage. Please contact Eijkelkamp; service
department.
c) Remove the new desiccant bag from its packaging and install in the same position as the old
desiccant bag (on the SIM card).
d) Carefully fold the stocking back.
45
Closing the modem housing
Once the battery and the desiccant bag have been replaced/installed, the modem housing may be closed again.
Step 6: Closing the modem housing.
a) Check whether the O-rings are damaged.
b) Check whether the top with the O-rings is dirt-free, along with the sealing surface in the housing
tube.
c) If no grease is visible on the surfaces, apply a thin layer of acid-free vaseline.
d) Turn the cover with the modem circuit and battery a half to a complete revolution to take up the
coiled cable (if necessary). This may be done in either direction.
e) Carefully slide the modem back into the housing tube and press the cover into the housing with
a light turning movement. Take note of the holes for the screws.
f)
Turn the two screws in hand tight.
Start up
Press the service key for 15 to 20 seconds to enter the configuration mode, the green LED will light.

service key again once for 1 second to switch the monitoring well modem on.
When re-configuring it is necessary to set the dial-out number for the home base (e-SENSE direct) in the monitoring
well modem by means of the configuration tool.
When changing the SIM card of the e-SENSE direct modem, it is necessary to set the dial-out number for the eSENSE direct modem in the monitoring well modem by means of the configuration tool.
6.3 Changing / replacing a sensor
 Ensure that:
- the new sensor to be used is off and does not contain any data
- the measuring interval on the new sensor has been correctly configured (this can also be done
subsequently using e-SENSE direct or on-site using the monitoring well modem configuration tool).
 Ensure that the modem is in configuration mode.
 Disconnect the battery connector to power down the modem.
 Replace the sensor and, if necessary, the cable.
Note: make sure the correct type of cable is used for the new sensor.
 Reconnect the battery.
 Install the desiccant bag and close the housing in accordance with the procedure as set out in section 6.1 (steps
5c to 6).

7. Tips for transport and storage of monitoring well modem
The modem can be shut down in various ways:
1. Remove the battery

Only do this if the modem is in configuration mode.
2. ‘Prepare modem for installation’ button in configuration tool: the modem will switch off and, once the
service key is pressed, will start the installation procedure.
3. ‘save all setting and shut modem down’ (save all settings and shut modem down) button in the
configuration tool: the modem will switch off and, once the service key is pressed, will go straight into
configuration mode.
When to use which method of shutting down?
If a modem is not to be used for a longer period, from a few weeks to months, it is better to disconnect the battery.
Even if the modem is switched off, it actually continues to draw a minimum amount of current and thus to drain
the battery.

All setting changes that have not yet been saved will be lost when the battery is
disconnected.
If a modem has been completely prepared for installation in the field (all settings are correct and the logger is
connected and properly set up) and the installation will happen fairly soon, it is sufficient to use the ‘prepare
modem for installation’ button. The battery can remain connected and the housing is closed in the correct way.
If a modem has been prepared but the logger is already out in the field, and the installation will happen fairly soon,
it is sufficient to use the ‘save all settings and shut modem down’ button. The battery can remain connected and
the housing is closed in the correct way. For installation, the logger only needs to be connected, and the service key
has to be pressed; once the modem has entered configuration mode, the logger settings can be changed if needed
and the modem is started up.
If a modem is not used for a short time and will be fully configured later, it is not necessary to keep the battery
connected.
