4. Power supply
Vehicle computer PP90W800A0J8 can be powered only by DC power supply
with nominal voltage.
Power supply voltage is connected to X1 connector, terminals +U and -U.
Terminal SB is used for vehicle computer switching on and off, terminal CHS for
connecting with computer chassis.

Computer start up and shut down
The computer power supply (terminals +U, -U and SB) is galvanically separated
from computer electronics. Galvanic separation must not be used for dangerous
voltages separation.
When installing, it is recommended to connect in single point of switchboard the
CHS terminal with chassis of equipment, where the computer is installed.
The power supply conductors cross-section must be at least 0.75 mm2.
The CHS terminal is internally connected with computer casing and with metal
caps of all connectors.
4.1.1 Computer start up and shut down
Terminal +U is used for connecting computer to the power supply. Device start
up and shut down is performed through SB terminal. After connecting power
supply voltage to SB terminal (terminal +U must be attached to power supply) is
switched ON the unit’s power supply, the SYS LED goes ON and the internal
piezo-buzzer shortly beeps.
Then follows start of operating system and user application is launched.

In terms of data consistence the unit’s start-up is not critical and can be realized
either by coincident connecting of power supply voltage to +U and SB terminals,
or by connecting the voltage first to +U terminal and then to SB, or vice versa.
Nevertheless, when starting up, an incorrect progress is not possible.

Fig. 4 - Correct computer start up / shut down
To prevent the data damage the computer must be shut down only by SB
terminal.
First, it’s necessary to disconnect the supply voltage from SB terminal, thereby
is initiated a correct process of systemic termination of application and
operating system run. Only after completion of operating system run and unit’s
shut down can be disconnected the supply voltage from terminal +U, or, voltage
can be connected to +U terminal permanently.
Together with initiating of systemic switch-off is activated the function of
dispatch processor for unit’s shut down. This shut down takes place after
elapsing of 1 minute, independently on the immediate state of systemic switch-
off. The time adjusted for shut down by dispatch processor must be longer than
time for correct software shut down of operating system. If it is not true, data
corruption can occur.

The core is based on Intel® Atom™ E680T processor and Intel® EG20T
chipset.
For more details see the COMe-mTTi10 module datasheet on manufacturer's
website (see the Related documentation section above).
As module storage device is used the flash memory. Therefore, when keeping
the memory lifetime in mind it is recommended to minimize the number of
writing cycles. Minimizing of number of writing cycles for Windows XP
Embedded is discussed in related Application note AP0024 –WXPE –filters for
Compact Flash protection.
5.2. Auxiliary processor module
Computer PP90W800A0J8 contains an Auxiliary CPU with CORTEX processor.
The Auxiliary CPU manages the internal sources of computer and takes care of
reliable start and run of Master CPU. The Auxiliary CPU also provides the
program watchdog functionality for Master CPU.
By Auxiliary processor commands you can
Read the data from the computer temperature sensor
To detect the FW version and revision of HW
Control indication LED
And other.
For detail list of functions and their description see the Related documentation –
PP9xxx series of vehicle computers –Programming manual.
5.3. SSD
Vehicle computer PP90W800A0J8 is equipped with additional SATADOM type
memory module. Memory module is connected to the system via SATA
interface. The system takes this module as a fixed IDE disc.
For more details about memory module see the manufacturer's website (see
the Related documentation section above).
For memory module size see technical specification.
As module storage device is used the flash memory. Therefore, when keeping
the memory lifetime in mind it is recommended to minimize the number of
