The logic make sense, it's true. However if you will be using an M4-ATX PSU you still need an LC filter.
great info everyone.
thanks very much.
the logic makes sense to me, looks like I will power the monitor off the power supply.
First Carputer in progress.....
I can't imagine a SMPS DC-DC converter passing reverse polarity - even a linear DC-DC for that matter!
The exception would be if fuses were replaced by 2" nails, and ALL series semiconductors failed in short circuit mode (not open), etc....
But granted, there are some amazingly crap systems out there that are capable of the impossible (from a normal "good" design POV lol!)
And a direct lighting strike kills just about anything. (lol - but an ouch-lol!)
However, I would like to learn of specific instances.... (and who made/designed/installed them!)
Car: 2004 GTI VR6 24v Turbo 2.8L, GT35R, 630cc, Unitronic, Bosch 044, etc, etc..
Main PC:i7 920@4Ghz, 6GB DDR3, MSI X-58 Pro-E, Win 7 x64 RTM, Scythe Mugen2, 128GB G.Skill Falcon, 2x ATI4850 512MB Crossfire, Auzentech X-Fi Forte, Grado Labs SR-80
Is it true that the Xenarcs will only hold brightness and contrast settings if powered from the cig lighter (i.e. consuming a small amount of power, not being completely shut off when the computer does)?
Or is the changing resolutions at boot up that erases the 800x600 bright and contrast settings?
yes xenarcs stay lit in blue screen mode, but they retain settings even if power is lost.. i keeo mine on all the time and tap it to the ACC line
I've got a xenarc too, but the settings ar lost when the power is off.. My monitor is connected to the switched 12v from the ignition, so the power is turned off with the key ..
unforunatly, if I lower the brightness en then turn off the car, and turn it on again en brightness is set to default..
xenarc 1020tsv saves settings, i have it:P
