Back Up System Help

[Jeff Miller]

LOL
I think that the tech support person knows nothing.

My take from the manual pages is that the lettering on the camera was
poorly translated from Korean or Chinese, and says "Magnetic"
and "Non-Magnetic" instead of "Mirrored" and "Non-Mirrored" so the
manual is trying to explain the correct switch positions. In a CRT
(not LCD) the horizontal and vertical deflection is magnetic, either
mirrored or normal, might be where the Chinese got confused, I've
seen lots of botched manual translations.

It appears that the monitor does the image-reverse, and is signaled
by the switch on the camera and utilizes an extra wire in the DIN
cable.

The signal is probably GND or +5v, could also be +12v / GND, but
without knowing which it is difficult to reverse the image manually.
Perhaps another tech support person will know more.

Again, the image in an LCD monitor can't be reversed magnetically,
they are unaffected by reasonable amounts of magnetic energy (unlike
CRTs), it will have to be reversed by a built-in software switch to
do the pixel-mapping backwards (which it apparently has if you can
figure out what the signal voltage needs to be).
