Question Honeywell Thor VM1C - Shortcut to trick the PSU ?

Greetings,

I have a Honeywell/LXE Thor device here : (VM1C - Windows CE, Intel Atom Z530 @1,6GHz)

Continuity measurement between all of the pins can be found at post 3.



It has a (backup) battery (10,8V 2500mAh) and a power button, but requires the dock (VM1D) attached to it, to turn the device on. I dont have that dock.
The Thor device is for vehicles and needs some Volts applied to some of the 50 back pins.





The dock has a 6 pin DIN adapter, that has to be attached to the vehicle battery. But I have no idea how to find the + and - pins on the back :





The dock (V1MD) would be connected to the back of the Thor System.
The "dock contact pads" on the Thor device, would be a seperate board with 2x 26 pins
IDC (insulation-displacement connector) male.

The 50 PIN pad connector on the back has its own board, incl. a ARM Cortex M3 (100 MHz, 32kB Flash, 8kB Data Memory)
NXP
LPC1751FBD80
SM0440.1 13
ZSD1124A

How to tell which one would be + and - to trick the device into "believing" it is actually connected to +12Volts ?




Maybe someone here has such a dock and had a look inside already ? Thanks in advance !

Continuity between the pins.
Same symbols/colors = continuity everywhere between each other.

PIN 49 and 50 have continuity between each other, but dont end anywhere else.
PIN 45,46 and 48 seem to be unused.

 
Is there a reason for not having or getting that dock?

If the dock is requirement (proprietary) then it is likely that any work arounds to avoid getting a dock are already in place.

For the most part trying to "trick" electronics often ends badly.

Either directly or when something else changes or gets changed.

It is good that you traced continuity etc. and are trying to make some sense of it all.

However without full schematics and any applicable troubleshooting and repair guides you are putting the Thor at risk.

A work around or "trick" is not something I would risk or recommend.

Im aware the THOR could die. Purchasing the dock was way too expensive, as I got this device for free.

I finally found 2 PINS (+/-) on the lower 26 pin connector, that end on another 2 PIN power plug on the mainboard.

Attaching 2 cables and slowly ramping up to 7 Volts, the power LED turned green, but I still couldnt switch the device on. For sure the other PINs ask for voltage too, as I didnt check all display pins and battery pins and so on. I had to gave up here, as after 2 minutes, a small "tick" sound appeared and the power led turned off.

Since then I havent tried again amd you are probably right, its dead now.
 
I understand this thread is dead, but it is referenced in a few other places recently and I found it first when looking for information.
did... did you get the polarity right ?
I put 12v into the unpopulated connector by the battery and it turns on and boots, idk
The polarity arrow is opposite of every other connector, if you just stare at the pcb the arrow side is clearly connected to the ground plane, but also it ohms out with the NEG on the battery too.

if that's not the case maybe you had a bad unit.

These four pins are usb.
If image goes away, that is
pin 11 5v
pin 12 data white
pin 13 data green
pin 14 gnd
