Hello friends,
For those who dont know what this controller is.
Connected this controller to your carputer and it shall be a blessing to your project this is how it works.
In total the unit has seven connection and three pots.
1) Battery (+12v from battery 24hurs a day)
2) Ground ( negative from battery 24hurs a day)
3) Out (connect to Inverter or dc - dc power supply)
4) ACC ( connect to acc of the car or a switch for manual on)
5) Pluse pin ( connect to mobo power on jumper positive side)
6) & 7) on/off ( turns on and off the carputer)
Pot 1 (marked 105)
Pot 2 (Marked 504)
Pot 3 (Marked 204)
Detailed explanation:
When you power the unit with +12v and negative (connection 1 & 2) from the battery the unit is charged and the relay turns on with red color Led lit at this time you will have to hit the on/off switch (connection 6 & 7 and turn the pot 2 till the relay turns off and the led goes off.
Now you connect the Acc (connectoin 4 ) to the cars acc connection and when +12 is sent through this line the unit is charged again and the relay is turned on with the led showing that the relay is on and the out (connection 3 ) has +12v on it this is where you connect the inverter or dc -dc PSu. At this time the ATX psu of the carputer goes in standby mode once you press the on/off switch (touching connection 6 & 7 ) will send a atx pluse to the mobo asking her to start booting. I suggest you start the car before hitting the on/off switch.
Now when you remove the key of cut power on the Acc line the unit waits till ~15 min can be set from 0~15min with pot 1 after the wait the unit sends a atx pluse to the mobo through connection 5 this pluse can also be set from 0~5sec using pot 3
after this operation the unit cuts the relay in 0~3 mins cna be set using pot 2 thus giving enough time for the carputer to shutdown.
Incase you turn the key back on in the first 15 mins wait time then nothing happens.
If you decide not to wait for the 15 min for shhut down then hit the on/off switch after you remove the key and the unit will send the atx pluse immediatly.
