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 1
st
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;
CU-07A; SN: 1400800017; ID: 671003; SW: 7.3; HW KW10403;
RK: ABH9P-HD89R-15GT; GSM: 57%; SAT: 9/10; Time: 15:36
26.3. “ in this order it includes information about, serial number,
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
where:
х
– journey type:
0

code, the function can be enabled or disabled permanently or it
can be activated for a single journey.

1111 SINFO ON (the unit sends a notification about the
commencement of a journey each time the ignition key is turned
on)
Command format: UCcode SINFO
Command example:
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)
Command format: UCcode GEOFENCE
Command example:
