2.3 Power Supply
The power supply of the Java Box Terminal has to be a single voltage source of POWER 6V-30V
capable of providing a peak during an active transmission. The Java Box Terminal is protected from
supply reversal voltage. An internal fuse ensures an electrical safety according to EN60950. This fuse
is not removable. A fast acting fuse 0.8A with melting is necessary to use with the Java Box Terminal
at a 24V power supply system for vehicles. The power supply must be compliant with the EN60950
guidelines.

is use for backup and supply the power to the modem only when the main power fail or when
the modem turn off the DC/DC power supply.
The Java Box automatically will switch from linear power supply to battery operation when the DC/DC
power supply stops 5V output.

2.4.2 Switch Off Java Box Terminal
There are several ways to turn off the java Box Terminal:
• Software controlled shutdown by AT command: AT+MRST
The AT command lets Java Box Terminal log off from the network and allows the software to
enter into a the secure state and safe data before disconnecting the power supply.
The mode is referred to Power-down mode.
• Via On/Off push button.
The Java Box Terminal will be switched off by pressing the On/Off push button or by
activating the On/Off signal for >2s.
• Via IGNITION line.
The Java Box Terminal will be switched off by IGNITION input line connected to GND.

Do not disassemble the product; any mark of tampering will compromise the warranty validity. We
recommend following the instructions of the hardware user guides for a correct wiring of the product.
The product has to be supplied with a stabilized voltage source and the wiring has to be conforming to
the security and fire prevention regulations. The product has to be handled with care, avoiding any
contact with the pins because electrostatic discharges may damage the product itself. Same cautions
have to be taken for the SIM, checking carefully the instruction for its use. Do not insert or remove the
SIM when the product is in power saving mode. The system integrator is responsible of the functioning
of the final product; therefore, care has to be taken to the external components of the module, as well
as of any project or installation issue, because the risk of disturbing the GSM network or external
devices or having impact on the security. Should there be any doubt, please refer to the technical
documentation and the regulations in force. Every module has to be equipped with a proper antenna
with specific characteristics. The antenna has to be installed with care in order to avoid any interference
with other electronic devices and has to guarantee a minimum distance from the body (20 cm). In case
of this requirement cannot be satisfied, the system integrator has to assess the final product against the
SAR regulation. The European Community provides some Directives for the electronic equipments
introduced on the market. All the relevant information’s are available on the European Community
website: http://europa.eu.int/comm/enterprise/rtte/dir99-5.htm

7. JAVA BOX GPS Options
This chapter provides options that can be use on the JAVA BOX GPS.
7.1 Battery Source Power
7.1.1 Battery Power
Single 3.7V LIPO cell battery type is use for supplying the power to the JAVA BOX The battery capacity
900mAh.
7.1.2 Battery Charge control Circuitry
The charging process for LIPO Battery divided into 4 phases:
• Qualification and trickle charging
• Fast charge 1 - constant current
• Final charge - constant voltage or pulsed charging
• Maintenance charge
The qualification process down by special internal chip, this chip is battery charger voltage regulator.
moreover all these operations should start only if battery temperature is inside a charging range,
usually 5°C - 45°C. The JAVA BOX measures the temperature of its internal component, in order to
satisfy this last requirement, it's not exactly the same as the battery temperature but in common
application the two temperature should not differ too much and the charging temperature range should
be guaranteed.
