Ⅳ. Operation instructions
(1) . ITPS instruction
A. Operationing principle instruction:
After connection the red LED of ITPS light, that means you can star up the unit then and further operation.
The ITPS will detect the high voltage from ACC when the you turn on ignition switch to ACC or start up the
automobile, if the duration of high voltage is more than 10s (this duration of high voltage will be re-recorded if the
high voltage broken off.),the green and white line will transmit boot-up signal to PC board. And then the PC will
start up properly. The green LED of ITPS will light after the PC started up.
After start up the PC you can set it to be standby/ sleep as following.
1 You can turn off the computer or to set the computer to be standby, sleep mode by the operation system.
○
2 When you turn off the ignition switch or take away the key it will cut off the voltage of ACC. And ITPS detect
○
0V voltage from ACC, the ITPS board will turn to delay turn off for 30s, after that a signal of turn off will be
transmit to the PC board by green and white line. So that the PC will enter into turn off program and turn off
safety,only +5VSB voltage supply for the main board. If some system of the computer can not close or system
halted, ITPS will keep waiting for 20s and then cut off the main power supply of PC compulsively, Only +5VSB
voltage supply for the main board.
③ If voltage of ACC get back again before the PC turn off safety after entering into delay turn off state ITPS will
not keep PC run normally. resume is high level, microcomputer
B. The protection of storage battery and others:
As the voltage range of ITPS is from DC 7V-20V, ITPS could detect the change of voltage and transmit the signal
via green white to control the PC. So that it will keep the battery out of over-discharge.
1. In standby mode if ITPS detect the voltage is less than 10.8v for 30seconds, the Red LED will light and refuse
to turn on the PC with ACC. The Red LED flicker once/s in this state. When
2. When the PC is on work if ITPS detect the voltage is less than 10.8v for 30seconds, the Red LED will light,
after 30s it will send out turn off signal which making the PC turn off normally. If the PC couldn’t turn off
normally or system halted ITPS will turn of PC compulsively.
3. In standby mode if ITPS detect the voltage is higher than 15.8v for 3s the Red LED will light and refuse to
turn on the PC with ACC. The Red LED flicker twice/s in this state.
4. When the PC is on work if the ITPS detect he voltage is higher than 15.8v for 3s the Red LED will light and
send out turn off signal which making the PC turn off normally. If the PC couldn’t turn off normally or system
halted ITPS will turn of PC compulsively.
5. In work mode the PC will turn off system normally in a delay time after the turn off signal was sent out and
enter into stand by mode. If ITPS detect that PS_ON hasn’t arrived a high voltage for 20s after the delay time,
it will send out a compulsively signal continues for 6s to turn off the PC compulsively. If there is something
wrong with the BIOS system, it will not work as mentioned above and the Red LED will light twice/s. Please
cut off the power supply and ask for a service.
6. The ITPS keep the battery enough power as mentioned above to start up automobile.
When the your automobile is out of use for a long time please disconnect the ITPS to the battery avoid the ITPS
exhaust the power of battery by low current. When the car is not use for a long time, pls cut the contaction of
automobile battery and ITPS power panel in order to avoid ITPS power panel exhaust the electric quantity of
the battery.

After connect to the power, the computer will be stand-by mode.
After connect to ACC and turn on the ignition switch,10s later computer will turn on normally, the PC will
turn off normally when you turn off ACC.
Push the POWER button on the front panel to turn on the computer, push it once more to turn off and
enter into standby state. Disconnect the power supply to exit standby state.
Please push the RESET button on the front panel to reset when the system halted.

The power indicator doesn’t light after you pushed the power button.
-Please check and make sure the power connection is correct and the power supply proper.
No sound
-Please check and make sure the audio lint is connected properly.
-Please check is the system is in MUTE mode or the volume is down to the minimum level.
-Check whether the driver of audio card is installed correctly.
Not display:
-Check whether the display work properly.
-Check and make sure the connection is correctly.
Couldn’t recognise USB.
-Re-insert the USB, so that the system will recognise it again.
-Insert to the other USB ports..
-Check whether the driver program is installed properly.
Display blue screen when you installing PWIN98SE.
Please check whether external hanging FDD (Floppy Drive Device), if not, please enter into
BIOS SETUP PROGRAM/STANDARD CMOS FEATURES/DRIVE A [NONE] AND INTEGATED
PERIPHERALS/ON-BOARD FDC CONTROLLER [DISABLED] or it will display blue screen when you
installing PWIN98SE.
Can’t enter into sleep mode. Recognize 160GB HDD as136GB HDD.
-160GB is a part of 48-bit HDD, it is supported by BIOS. The last BIOS can recognize it.
7.
How to start the USB2.0 function?
Because of ICH4 this unit can read four USB2.0.
We suggest that install WINXP SP2 so that it needn’t a driver for USB2.0 and could read the USB2.0, then
work normally as transmission rate of 480bit.
8.
Couldn’t find the HYPER THREADING.
This unit support HYPER THREADING, but is only work in P4 which HYPER THREADING. So that you
need to install P4 before operate on it.
Windows XP and LINUS2.4 X support H-T function.
9.
What kind of operating system support H-T function?
WINDOWS XP and WIN 2003 can support HT function.
Please reference to http://www.intel.com/support/platform/ht/os.htm for more details.
