What About the Screen?
Powering and turning on and off screens is not directly supported by
the CarPC Pro or EZ Power Controllers. That said, please continue reading
for viable solutions to that issue. There are several options, one of
which should work for your situation.
Options:
1) We commonly use PC LCDs that require being plugged into the inverter
(because they are larger and less expensive). Therefore, it receives power
when the Power Controller turns on the inverter. And, most PC LCDs automatically
turn on when they are plugged in and sense the PC on. Therefore, you don't
need to worry about it.
2) If you are using a mobile (made for car) screen, it may have a remote
turn on line. If this is the case, simply use the amp turn on lines (marked
#5, step 6 in the manual) the same as you use them to turn on an amplifier.
3) If using the mobile screen without a remote turn on line and an inverter
to power the PC, then you will have to manually turn on and off the screen
or connect it to the ignition or the switched line that turns on the head
unit.
4) If using the mobile screen without a remote turn on line and NOT using
the inverter to power the PC, then you can use the inverter control wires
(marked #4, this would replace step 5 in the manual) on our Power Controller
to turn on the screen. Simply connect one line to +12 and the other to
the power on the screen.
The reason Option 4 is possible is that the two wires marked #4 (for
the inverter turn on) are the contacts on a relay. It is enough to supply
moderate power (a few amps) to anything you want. |
