1. GENERAL DESCRIPTION
The Mobeye CML2275 is a GSM module used to monitor the temperature using one
or two temperature probes. As soon as one of the temperature limits are violated or
one of the inputs are activated, it sends alarm notifications. The unit can run battery-
powered. When powered externally, the power supply will be monitored too. If
connected to the web portal, the temperature values are logged and transferred to the
web portal.
The Mobeye CML2275 is pre-programmed with standard behaviour. To change this
behaviour please refer to chapter 4.
The factory settings of the Mobeye CML2275 cause following reactions:
- In case of a temperature alarm, the Mobeye CML2275 sends an alarm SMS text
message and calls the phone numbers as programmed. The SMS message contains
the text ‘Temperature too high’ or ‘Temperature too low’, followed by the measured
temperature. If two temperature probes are connected, the message will include the
indication which probe is in alarm status.
- As soon as the temperature gets back to a value inside the range, an SMS text
message is sent to the programmed phone numbers containing the text ‘Temperature
OK’, followed by the measured temperature.
- If one of the inputs is activated by a sensor, the Mobeye CML2275 sends an alarm
SMS text message and calls the phone numbers as programmed.
- If one of the temperature sensors is removed, the Mobeye CML2275 sends an alert
SMS text message to the administrator (first telephone number).
- If an external power supply is used and a power failure occurs, the Mobeye CML2285
sends a ‘power failure’ SMS text message and calls the phone numbers as
programmed. If the power is restored, the Mobeye CML2285 sends a ‘power
restored’ SMS text message to the numbers.
- If the batteries need to be replaced, the Mobeye CML2275 sends a ‘battery low’ SMS
text message to the administrator.
- For all types of alarms a local alarm indication will sound, which can be interrupted by
briefly pressing the button.

6
If the Mobeye CML2275 is connected to the Mobeye Internet Portal, additional
functions are active:
- The configuration of the Mobeye CML2275 can be done either via the web-based
environment or via the SMS commands as described in this manual.
- In the event of an alarm situation, the Mobeye CML2275 will call the phone
numbers as programmed and send a message to the portal. The portal will
despatch the message to contact persons (SMS and/or e-mail), which are
preconfigured in the portal. The receivers of the alarm messages can differ from
the receivers of the technical messages.
- Logging of the temperature values. As default the temperature values are
measured and logged every 60 minutes and sent to the portal every 12 hours.
The log frequency and synchronisation interval can be adjusted.
- The display of the status and historical events.
- The unit can be given a name and location in the portal, which are used in SMS and
e-mail messages.
- Once connected to the Internet portal, test messages ("keep alive") are sent
regardless the unit is armed or disarmed. The portal will monitor the receipt of the
test messages; if it is not received in time, the portal sends an exception
message to the - set in the portal - (service) contact persons. In this way the
communication between the Mobeye CML2275 and the portal is checked
(default: every 7 days).
See www.mobeye.eu/portal for more information. The portal can be accessed via
www.mymobeye.eu.

2. GETTING STARTED
To get started with the Mobeye CML2275, at least the following steps need to be taken
in the following order:
1. Insert a SIM card
2. Connect the temperature sensor(s)
3. Insert the batteries
4. Enter the program mode
5. Program at least one telephone number
6. Enter a value for the temperature limits
7. Arming/disarming the system
These steps are further explained in this chapter. After these steps the module will be
operational.
2.1 INSERT A SIM CARD
Open the enclosure by removing the 4 screws and insert a SIM card into the module.
Push the black cover slightly outward to open the holder. Before installing the SIM
card should have PIN code "0000", or PIN code removed.
(A PIN code can be changed or removed by putting the SIM card in to any mobile phone and entering
the 'security' menu)
NB: Make sure the SIM card is inserted before the batteries are inserted. If you
replace a SIM card, first remove the batteries (and remove any other external power
supply). The settings are stored in the device memory.

8
2.2 CONNECT THE TEMPERATURE SENSOR(S)
Plug the external temperature sensor into the socket on the PCB (sensor 1) and press
it firmly. It is possible to connect two temperature sensors.
Then insert the sensor head through the swivel to outside. It is possible the bring out
only the a part of the head of the sensor, or the entire sensor with a part of the cable,
depending on the application. Close the swivel by turning it in order to reduce the
tensile strength and make it waterproof. A second sensor can be connected in the
same way on second sensor.
2.3 INSERT THE BATTERIES
Insert the two batteries (CR123) in the module. Use the +/- indication for the correct
placement.

9
2.4 ENTER THE PROGRAM MODE
In order to program the unit, the GSM module needs to be open and connected to the
network. Using external power, the unit is always in program mode.
A battery-operated unit switches to the program mode after inserting the batteries.
First the GSM module establishes network connection. During this time the LED
flashes green and red. Within 10-30 seconds the connection is established and the
status LED starts flashing 1 sec. on/1 sec. off (or stays on continuously in case the first
telephone number has been configured).
The Mobeye CML2275 returns to the program mode by pressing the button for 5
seconds, until the LED starts flashing red/green. Once it has GSM connection it will be
flashing again (or stays on continuously).
As long as the unit is in program mode, the status green LED is on (or flashing 1 sec.
on/1 sec. off if the module has no configuration). During the first 3 minutes, the GSM
module remains active, ready to receive SMS commands. After 3 minutes a time-out
occurs and the GSM module switches off in order to save the batteries. The unit
returns to the low power operational mode.
2.5 PROGRAM AT LEAST ONE TELEPHONE NUMBER
The Mobeye CML2275 is able to send messages up to 5 telephone numbers. The first
telephone number (TEL1) belongs to the administrator. Technical messages (such as
battery low) are sent to the administrator only. Without the administrators’phone
number, the Mobeye CML2275 cannot function.
When the CML2275 is in initial (factory) status and the batteries are inserted (so the
LED is flashing), the administrators’number is programmed by calling the telephone
number of the Mobeye CML2275 using the administrators’ phone. The unit will
recognize this number and store it as administrator (TEL1). The administrator will
receive a confirmation SMS text message including the security code. This code is
needed to program the other settings in the unit.
NB: For this way of programming the number recognition in the administrator’s phone
must be ‘on’. To program or change the administrators’ number by SMS command,
please refer to 5.2.

10
2.6 PROGRAM THRESHOLD VALUES FOR THE INPUTS
A separate high and/or low temperature limit can be set for each temperature sensor.
All limits can be set between -35 and +70 ºC. Negative values are set by placing a “-”
in front of the value.
To enter a temperature limit, be sure the Mobeye CML2275 is in program mode. Send
an SMS text message to the unit with following content for the first sensor:
SMS command lower limit: 1111 LTL1:
example: 1111 LTL1:-5
SMS command upper limit: 1111 HTL1:
example: 1111 HTL1:25
Similar for the second sensor:
SMS command lower limit: 1111 LTL2:
SMS command upper limit: 1111 HTL2:
Please mind the space behind 1111.
2.7 SWITCHING ON/OFF
After the previous steps, the Mobeye CML2275 is ready for use and switched on
automatically. It can be switched on and off by the user-defined time schemes or the
button on top. By default this button is ‘locked’, to prevent that the unit can be switched
off by mistake. This can be changed by choosing the value “OFF” for the setting
“BUTTONLOCK” (see 6.20). After unlocking the button, the system can be switched
on and off pressing it for one second.
When the unit is switched off, the green LED is off. When the unit is on, the green
LED blinks once every 3 seconds (battery-powered) or stays ‘on’ continuously (in case
of an external power supply).
In the disarmed status the Mobeye CML2275 will not send alarm notifications. The
functions automatic arming and sending a ‘low battery’ message, are still active.

11
2.8 CONFIRMATION OF THE ALARM MESSAGE
When the system is triggered it will send alarm notifications. First an SMS text
message is sent to all programmed alarm numbers, followed by a phone call. When
you pick up the phone, you will hear beeps. It is possible to confirm the phone call by
answering the phone and pressing any key. The other alarm numbers will not be
called afterwards.
By switching off the ‘SMS’ function, the system will only call. This prevents the other
numbers being notified by SMS.

12
3. USE OF EXTERNAL POWER SUPPLY
Although the Mobeye CML2275 is designed to run on batteries, it is possible to use an
external power supply. In this mode the module is always connected with the GSM
network and therefore always in program mode. When the power fails, the batteries
take over and a power failure message is sent. The module continues operating albeit
in the low power mode. This means the GSM module switches off and only establishes
network connection when it needs to send an alarm notification, test message or low
battery alert.
Connect the external power adapter (or any
other regulated 12VDC power supply) to the
power input of the connector (press on the
green pins to connect the wires):
- V+ (black lead with white stripe) to “+”
- Ground (black lead) to “-“

13
4. USE OF THE INPUTS AND OUTPUT
4.1 CONNECT A SENSOR TO THE INPUT
It is possible to connect two external sensors
to the inputs. As a standard reaction after a
triggered input, the Mobeye CML2275 sends
an SMS text message to the preset numbers
and calls these numbers.
Insert the 2 wires of an external sensor
through the hole of the enclosure to the
inside part and next in the two connectors of
input 1 (press on the green pins for
connecting the wires). It does not matter which wire is connected to which connector.
When using a second input, connect this to input 2.
As default the inputs are programmed as Normally Open (NO) contacts. This means
the inputs are triggered if the input is closed for at least 1 second. In case the contact
is Normally Closed (NC), please refer to paragraph 6.8. If you require the sensor to be
activated for a shorter or longer period before triggering an alarm, please refer to 6.8.
4.2 CONNECT A DEVICE TO THE OUTPUT
The Mobeye CML2275 has an open collector
output, which switches after receiving a
correct SMS or after an alarm. The output
can switch permanently, or just switch for a
pulse time after which the output
automatically switches back (see 6.15).
The maximum load of the output is 200mA.

14
To switch devices, a relay can be placed behind the output with an input voltage of
12VDC. The required switching voltage of the relay depends on the device connected.
NOTE: The output does not work if the CML2275 is battery-operated.
4.3 CONTROL THE OUTPUT VIA SMS COMMAND
If CML2275 has external power, the GSM module is always open, able to receive an
SMS command to switch the output. The output type needs to be ‘RC’ (see next
paragraph).
To switch the output, send following SMS command to the unit:
CODE O1ON
example: 1111 O1ON
To switch off the output, send following SMS command to the unit:
CODE O1OFF
example: 1111 O1OFF
Be aware of the space after 1111.
The output has a pulse time of 5 second in the factory defaults (see 6.17).
4.4 OUTPUT BEHAVIOUR
The output can be switched by SMS command when the unit is powered externally, or
automatically after an alarm (ALARM). The output remains on as long as the unit
remains in alarm status. For controlling the output via SMS command the output
behaviour should be ‘RC’ (remote control). The pulse time defines the duration of
switching (see 6.17). By default, this value ALARM.
To set the output behaviour, send following SMS command to the unit:
OUTPUT:
example: 1111 OUTPUT:ALARM

15
5. CONFIGURATION
To program the Mobeye CML2275, the GSM module must have network connection.
In case only batteries are used, first switch the unit to the program mode. Next send
SMS commands for the configuration. All settings are stored and will be kept in the
unit, even in case the power supplies are removed.
5.1 PROGRAM MODE
If the unit is connected to an external power supply, the CML2275 has continuous
network connection and the unit is permanently in program mode.
If the unit is battery-powered the program mode can be achieved by pressing the
button for 5 seconds, until the LED starts flashing red and green. Alternatively, the
program mode can be accessed by (re) inserting the batteries.
First the GSM module establishes network connection. During this time the LED
flashes green/red. Normally this takes 10-30 seconds. Once the connection is
established the status LED starts flashing 1 sec. on/1 sec. off (or stays on continuously
in case the first telephone number has been configured).
In program mode, the device is ready to receive SMS commands. If no correct
command is received for 3 minutes, the GSM module switches off in order to save the
batteries. The unit returns to the low power operational mode.
The program mode is interrupted by pressing the button for one second until the LED
switches off. The unit is switched off completely (disarmed).

16
5.2 THE (SECURITY) CODE
For configuration activities the (security) code of the Mobeye CML2275 must be used.
The initial (security) code is ‘1111’. You can change the (security) code to your own
code. See section 4.4.
5.3 PROGRAMMING THE SETTINGS BY SMS
To program the settings by SMS text message:
1. Make sure the CML2275 is in program mode (please refer to 5.1).
2. Send an SMS text message with the (security) code and the command.
3. The green LED blinks 3 times to indicate the successful configuration. In case of
an incorrect command, the red LED flashes 5 times.
SMS messages have the following content: CODE COMMAND:OPTION
- Do not forget the space character between (security) code and command.
- The commands are case insensitive.
- Several commands may be combined in one SMS message (with a maximum of
160 characters) by placing a # between the commands.
CODE COMMAND:OPTION#COMMAND:OPTION#COMMAND:OPTION
See section 5.4 for a full list of SMS commands.
