Preparation and operation of intelligent terminal
before installation
Preparation before installation
1.Contact the relevant person in charge to open the
platform login user name and password.
2.Open the SIM card for GPRS data service. At the
same time, you must apply for a SIM package for
your SIM card. You can apply for 10M or 20M or 50M.
The minimum billing unit of the SIM card shall be in
bytes (BYTE). The traffic used by the device for

normal operation: 5~8M for 1 minute monitoring, 10~
12M for 30 seconds monitoring, and the flow rate unit
is byte.
3.Record the relevant vehicle information such as the
SIM card number and the vehicle license plate
number to be installed, and use the open user name
and password to log in to the online car or CS version
of the client software to add information about the
fleet, vehicle, etc. (Ps: system when loading The
number must be 15 digits starting with 860013, such
as: 860013512345678)
4.Before installing the GPS vehicle terminal on site,
connect the GPS vehicle terminal and the complete
set of accessories (the accessories to be installed to
the customer) in the indoor test environment, and
supply power to the GPS vehicle terminal with the s
tabilized power supply to ensure the GPS vehicle
terminal and all accessories. Can work normally.
4、Installation Precautions
4.1.Firstly check whether the vehicle power supply
voltage is normal and whether its voltage range
meets the power supply voltage range of the GPS
vehicle terminal. When selecting the power supply,
the power supply should try to select the main power

5、
supply of the vehicle (the power cable directly
connected to the battery);
4.2. When selecting the installation position of the
GPS vehicle terminal, try to keep away from the car
electronic equipment and other heat source devices,
especially the wireless equipment and high-power
electronic equipment, and install it firmly to avoid
damage to the GPS vehicle terminal due to long-term
large vibration;
4.3.The antenna is an all-weather product that can be
installed in a suitable position inside and outside the
car. Concealed installation is recommended to be
installed on the back of the front panel plastic cover,
the back of the trunk cover or other plastic products.
Note that the GPS antenna must have a certain visible
sky range, not by the metal casing, coated glass Etc.
4.4.Do not plug in the SIM card with power to avoid
burning the card.
Installation
5.1、Warm tips
The power cable is recommended to be connected
behind the car main switch or on the car battery line.

5.2、Installation steps and parameter settings:
①Disassemble the screws and insert the SIM card
into the SIM card holder on the circuit board. When
taking the circuit board, please be careful not to
touch the components on the circuit board as much
as possible to avoid static damage to the circuit
board.
②Turn on the backup battery switch. Under normal
conditions, the circuit board starts to charge and the
indicator light is on;
③Select the car power access point and connect the
external input power to the terminal;
④After the lights are flashing normally, you can start
the parameters of the SMS setting terminal. The
specific setting instructions are as follows:
SS,*CMNET*,**,**,*IP*,*port*,*device system number
*,*sim card number*,*123456*
*APN：Telecom carrier access address, such as
CMNET;
*PORT：server port;
*IMEI number：device ID，11-digit length number
starting with 13;
*SMS service number: The service short signal will
be applied when the terminal actively reports the

After-sales service
alarm. The national number must be added before
the number. For example, the domestic 13512345678
should be *[phone]*. The service SMS
number is the corresponding target number when
the SMS message service is opened.
*SMS verification password: The factory default is
123456, which must be 6 digits;
EG：
S,*CMNET*,*28.60.185.172*,*9999*,*13512345002*,
*[phone]*,*123456*
⑤After the terminal normally logs in to the platform,
install the circuit board into the outer casing, fix the
panel with screws, fix the terminal and antenna in the
proper position, and arrange the cable, restore the
car line and the removed part of the panel, and the
installation is basically completed.
Terminal remote restart command: R, *PASSWORD*
Time zone adjustment: Adjust_Time, time zone,
*PASSWORD*
Working interval setting: SET+TIME=T1, T2, *123456*
T1 indicates the ACC open transmission interval, and
T2 indicates the ACC open transmission interval.
Set the SMS response number above to send the
number of the SMS mobile phone.

6、Standard accessories
Precautions:
The parameter input must be correct. Otherwise, the
platform cannot be logged in normally. It is
recommended to use the short message T command
to query whether the parameters are correct, and
check whether the terminal is online normally on the
monitoring platform.
6.1、Accessories
Standard: Power cord, Velcro, warranty card,
warranty card receipt, certificate
7、General troubleshooting
and maintenance knowledge
①1 Do not soak the device into the water.
②2 Keep the car battery fully charged and working
properly.
③3 When the vehicle is under the building, tunnel or
high building, it will affect the GPS signal and the
reception of GPRS and CDMA
communication network signals, causing the
equipment to work abnormally; when the vehicle

drives out of the above area, the equipment will
automatically recover.
④4 The power supply of the device is between 9V
and 33V DC. The recommended working voltage is
12V or 24V. The installation should first determine
whether the user's power system is within this range.
Exceeding the maximum voltage of the terminal will
damage the terminal.
⑤5 When the external temperature exceeds the
normal working range of the terminal, the terminal
should stop working.
⑥6 When the terminal is powered on, please do not
plug or unplug the antenna to avoid damage to the
terminal.
⑦7 In case of abnormality, please do not repair it
yourself. The manufacturer is not responsible for the
damage caused by connecting the non-original
accessories or unplugging the connections between
the components.

3.If the device’ GPS function is normal, but can not
locate for a long time, please check whether the
installation setup of device is correct:
1)Please make sure the GPS antenna face is up;
2)Please make sure there is no electromagnetic wave-
absorbent object (metal) above the device, especially
the thermal-protective coating on the windshield, it
may affect the GPS reception of the device;
