Zenith Power Supply Pinout PS/Note N45 SL

[solidpro]

Hi All

I've got two N45 SL machines but I can't test either of them without the weird Zenith power supply. Does anyone know a source of this weird kind of connector and does anyone happen to know the pinout?

The manual shows it's 22v but I don't know which pin is which...

Here is a pic of the socket:



Here is a pic of the specification (in italian):

It's almost impossible to find, so I built my own. The connector is a very unusual 4 pin connector which is a bit bigger than a S-Video or PS2 male connector. However if you remove the outer shield from either of those, it'll fit, with the S-Video connector having the key in the right position.

If you look directly at the socket on the side of the PS/Note, the top left hole is GND and the bottom 2 pins either side are 22v +
One is for battery and one for 'power' but I found you have to power both for the machine to turn on, whether it has a battery or not. I tested with a variable power supply and it draws a max of about 1.4amps so you need anything +19 / 2a really and you should be in business.
