CU-07A Tracer unit 1/4 MKW51604
CU-07 A TRACER unit
1. Unit description
The CU-07 A Tracer unit is a device which uses a GPS receiver to
detect the position of a car, a motorcycle or cargo. The position can be
ascertained any time via a single SMS command or it can be sent
during the journey via the GSM network to the mass storage server of
the web application where data are managed for online monitoring
and the trace log. Simply said, the unit can be used both for passive
locating when it only answers a single command, and for the
continuous transmission of real-time data to a data-collection server. If
the attempt to send the data fails, the unit saves it in its internal
memory and sends it later.
Start of the journey – The accelerometer triggers the GPS
module when car starts moving. It starts immediately with locating.
The start of the journey is indicated by a permanently lit LED until
the journey is finished (optional parameter).
End of the journey – The journey is finished automatically with
a 5 minute delay from the moment the car stops. If the car
continues with the journey during this 5 minute interval then the
journey won´t be split into independent traces. This eliminates
splitting the traces because of waiting at crossroads for example.
2. Unit installation and connection
2.1. Unit installation
The unit should be installed in the vehicle interior by a professional
company. It is suitable for vehicles with a 12 V or 24 V power supply
and a negative earth.
Disconnect the battery before installation. Nobody should be inside
a vehicle equipped with airbags while handling the battery. Some
devices equipped with a memory (clock, configurations, etc) could be
erased when the battery is disconnected. Avoid drilling into metal parts
of the car body during installation. The manufacturer shall not be held
liable for any damage caused by incorrect or unsuitable installation of
the product.
2.2. Unit installation in the car
We recommend installing the unit on or under the dashboard or at a
place where it has a good view towards the sky. It is true for the
correct functioning of the GPS module that the wider the angle
through which the antenna can see the sky through the
windscreen, the more precise the GPS location function is. There
must not be any other metal objects under or above antenna. Always
install the unit according to the described orientation which means the
lettering pointing down towards the ground.
2.3. Wire connections
Visibly installed unit can be easily connected to circuits of the car
via the connector into the car socket for car lighter. If the unit is
installed as a hidden or is permanently used in one car, we
recommend to cut the connector and wires connected directly to
the electric installation of the car.
•Black - ground – connect to the original earthing point.
•Red - +12 V (+24 V) power supply - connect to a cable leading
from the battery. The power supply should only be connected after
a thorough inspection of the whole installation!
•White – panic input, reacts to grounding to the GND wire.
Default: not used.
2.4. Status indication with an LED indicator
The unit indicates its status with an LED indicator.
Slow flashing Logging into the system or the GPS
signal has been lost
Rapid flashing The unit is waiting for configuration

supply has been disconnected
2.5. SIM card
The SIM card is first inserted into its moveable holder then into
the fixed holder on the PCB from the side of the unit. The
moveable SIM card holder ejects when yellow button is pressed in
the direction of the arrow visible on the unit. Mind the correct
orientation of the SIM card and press the holder to the stop.
3. Basic unit configuration
3.1. Language selection

3.2. Master code setting
The master code serves for unit programming and control. It is
therefore intended to be used by a service technician or a multiple
unit administrator. The master code can also be used to change
user codes. The default master code is 1234. The manufacturer
recommends changing this password. The MC code must
contain 4 to 10 characters. All characters from A to Z and from 0 to
9 are accepted, it is not case-sensitive.
Command format: MCcode MC newMCcode newMCcode
Command example:
1234 MC CU654321 CU654321 (the new code will be CU654321)
3.3. Changing the user code
The user code serves for user control of the unit. It is usually
used by a driver or a unit user. It is not possible to change the
master code using a user code. The default user code is 1111.
The manufacturer recommends changing this password. The
UC code must contain 4 to 10 characters.
Command format: UCcode UC newUCcode newUCcode
Command example:
1111 UC AUTO988 AUTO988 (the new code will be AUTO988)
3.4. Data transmission to a data-collection server
If you want to transmit data from the unit to a data-collection
server in order to process it into a vehicle logbook, ask the service
provider who will then carry out the setting.
If you would like to use the unit for passive SMS location, no
other settings are required.
3.5. Configuration entry mode timeout
Rapid flashing of the unit's LED indicator informs you that the
unit has not been configured yet. If you therefore intend to transmit
data to a data-collection server, the flashing ceases as soon as
the operator carries out the configuration.
If you are planning to use the unit only for non-server
configuration, the flashing will cease once you have entered a
TEL1 telephone number (see 4.1).
4. Advanced unit configuration
Perform advanced configuration using the C-Link application
remotely via the GSM. Download the C-Link software at
www.jablotron.com.
The unit can also be programmed by SMS command or sending
multiple commands in one SMS. Such a command must begin
with a password followed by individual commands separated with
a comma.
Command example:
1234 TEL1 [phone],TEL2 [phone],VERIF ON ….
4.1. Entering drivers’ telephone numbers
If the unit is installed in a vehicle which is used by multiple
drivers, it is possible to select the driver who is going to drive the
vehicle easily by dialling into the unit from the driver’s telephone.
The device memory can hold telephone numbers of up to 99
drivers who can identify themselves by dialling into the unit. The
telephone number can consist of 12 digits maximum and it must
be entered in the international format. It is recommended to
enter the telephone number of the company vehicle fleet
administrator at the TEL1 position as all unidentified SMS
messages which the unit receives (see 6.1) are sent to this
number.
Command format: MCcode TELx +yyyyyyyyyyyy
where: x– the unit’s reference (indexing) number of the
telephone number (from 1 to 99);
yyyyyyyyyyyy – telephone number in international
format (max.12 digits excluding the + sign)
Example of a command programming numbers 1 and 2:
1234 TEL1 [phone],TEL2 [phone]
4.2. Entering PANIC telephone numbers
The unit can send an SMS and dial in up to two telephone
numbers when the driver is in distress and activates the panic input
e.g. with a button. The minimum activation time has to be 1 s.
Command format: MCcode TELPANICx +yyyyyyyyyyyy
where: x– the unit’s reference (indexing) number of the
telephone number (1 or 2);
yyyyyyyyyyyy – telephone number in international
format (max.12 digits excluding the + sign)
Command example:
1234 TELPANIC1 [phone], TELPANIC2 +420 …
4.3. Entering a telephone number for sending journey
commencement notification
The unit can send notifications about the commencement of a
journey or leaving a given area to a preset TELINFO telephone
number. Area leaving parameters must be set according to the
following paragraph. These functions can be switched on/off by
individual users (see 5.3. and 5.4).
Command format: MCcode TELINFO +yyyyyyyyyyyy
where: yyyyyyyyyyyy – telephone number in international
format (max. 12 digits excluding the + sign )
Command example:
1234 TELINFO [phone]
4.4. GEOFENCE vehicle position guarding
It is possible to set the GEOFENCE function in the unit for
monitoring abandonment of a delimitated area.
Command format: MCcode GEOFENCE xx:yy:z
where: xx – geographical latitude coordinates in whole degrees
with +/- sign (can be requested from the unit by the SMS
command GPS)
yy – geographical longitude coordinates in whole
degrees with +/- sign (can be requested from the unit by
the SMS command GPS)
z– radius of the circular area detected in km – allowed
values 1 - 99
Command example:
1234 GEOFENCE +50.7290:+15.1766:5
As the unit could leave the area several times per day or hour, it
is also necessary to set the number of SMS messages which it
could send in total. This parameter has to be set otherwise it will
not work.
Command format: MCcode GEOFENCE SMS h:d
where: h– the total number of SMS messages sent per hour
(the permitted value is 1-99, while 0 is the default)
d– the total number of SMS messages sent per day (the
permitted value is 1-99, while 0 is the default)
Command example:
1234 GEOFENCE SMS 5:10 (the unit sends a maximum of 5
SMSes per hour but it is limited to 10 SMSes per day in total)
4.5. LED signalling during the journey
The unit signals the course of journey monitoring with a
permanently lit LED. This function is optional, though.
Command format: MCcode LED ON/OFF
Command example:
1234 LED OFF (the LED will not be lit in the course of a journey)
4.6. Ascertaining the position via T-Mobile Locator
The LOCATOR command works only with an activated T-Mobile
Locator service (Where is…). When activating the service you
have to choose an LPIN locating code which must be entered as
one of the parameters in command setting. The setting is carried
out via the below-mentioned command. When it is submitted, the
unit sends an inquiry to the operator who then sends back
information about its position which the unit subsequently forwards

CU-07A Tracer unit 3/4 MKW51604
to the number from which the command came. This can take up to
two minutes. It is not necessary to send the whole command to
ascertain the position again. Sending a LOCATOR command is
sufficient.
Command format:
MCcode LOCATOR 5727 5727 KDE LPIN xx...x
where: 5727 – is the number of service to which the inquiry is sent
5727 – is the number from which the unit expects to
receive an answer (it is usually an identical number).
KDE – is a service name
LPIN – is a code used for T-Mobile Locator service activation
xx...x – is a unit SIM card telephone number
Command example:
1234 LOCATOR 5727 5727 KDE 12345678 737231897
4.7. Ascertaining a pre-paid card balance
The manufacturer recommends using SIM cards with a flat-rate
tariff. When using a pre-paid card there is a danger of a loss of
functioning due to credit depletion or exceeding credit
validity!!!
By sending a CREDIT command it is possible to ascertain the
credit balance on a prepaid card and concurrently activate
periodical checking. The setting is carried out via the below-
mentioned command. When it is submitted, the unit sends an inquiry
to the operator who then sends back information about its credit
balance which the unit subsequently forwards to the number from
which the command came. This can take up to two minutes. It is not
necessary to send the whole command to ascertain the credit balance
again. Sending a CREDIT command is sufficient.
Command format: MCcode CREDIT uuu..u xx yyy zz
where: uuu…u is a command to ascertain the credit
(for example ∗101#T-mobile Czech republic)
xx is the period for ascertaining credit in days
yyy is the minimum amount of credit in CZK
zz is the position at which the number stating
the amount of credit in an SMS from an
operator starts
Command example:
1234 CREDIT *101# 7 200 1
This command will check whether the credit balance exceeds a
money value of 200,- every 7 days (the information starts at the 1st
character position in the SMS from an operator). If a lower amount
of credit is ascertained, the message from the operator is
forwarded to telephone number 1. The function can be disabled by
sending a command with a zero value of credit set (xx=0).
4.8. GSM module reset
In order to set some network functions it is sometimes required
to log the SIM off the network and then log it on again. In such a
case the unit’s GSM module can be restarted with the RESET
GSM command.
Command format: MCcode RESET GSM
Command example:
1234 RESET GSM
4.9. Service command DINFO
DINFO can give you the basic service information about the unit
and its status. Unit reply by SMS: “Your unit reports: CU-07A;

unit ID (as it was set), SW and HW version, internet reg. key,
GSM signal strength in %, number of used/visible satellites, time
and date.
Command format: MCcode DINFO
Command example:
1234 DINFO
4.10. Command verification
The verification command sets a condition that user commands
must contain the MC or UC code. This command can be used in
cases when the vehicle fleet administrator does not want to let
individual employees registered as drivers use user commands
(i.e. employees not knowing the password will not be able to locate
themselves or change the journey type or driver).
Command format: MCcode VERIF ON/OFF
Example of a command enabling verification:
1234 VERIF ON
5. User commands
User commands can be sent from registered telephones
without the MC or UC code, unless the VERIF command is
enabled.
5.1. Driver selection by an SMS command
A driver can also be selected with an SMS command (e.g. a
function for a dispatcher). In order to change the current driver’s
number you have to enter the following command:
Command format: UCcode Dx
where: x– is a driver’s number from 1 to 99
Command example:
1111 D2 (to set driver 2)
5.2. Journey type setting
Choose the journey mode by SMS.
Command format: UCcode Tх

1111 SINFO (the unit sends a one-time notification about the
commencement of a journey)
5.4. GEOFENCE function
If the GEOFENCE function parameters have already been set
using the MC code, if enabled then the unit sends an SMS to
TELINFO when the pre-set area is left. The function can be
enabled or disabled by a user.
Command format: UCcode GEOFENCE ON/OFF
Command example:
1111 GEOFENCE ON (the unit sends a notification each time it
leaves the area)
