Lilliput 7" Cable help needed. (Bad 9pin DIN)

FireAnt · 03-22-2005, 01:12 AM

I recieved my new Lilliput Model 629GL-70NP/C/T just last week and the 9 pin DIN connector has gone bad (lost 2-4 wire connections internally, Not pins).

I want to cut it out and splice/solder the wires back together. Can some one with the same cable use an Ohm meter and tell me which pins to connect together. Just keep your 9 pin Din hooked together and test for continuity between the tan connector that hooks to the lilliput and the Vga/ USB connectors on the other end.

Thanks for any help, I really want to use this new toy

This is the monitor

Here is the cable with the problem:

The monitor end plug:

The VGA connector

The USB connector

Please just fill in the blanks: Updated 3/29/05 I think this is it now

Da**, i have the samme problem...
got my screen last week, and already the plug is bad...
turns the screen almost totally black when it gets the bad connection
but is it the extension cable (the long one) witch is bad, or the plug, or is it the short cable(with the SKS Jack) ???

DorkVonWaterfal · 03-22-2005, 02:07 AM

i just wrote the seller i Honkong a mail, hope to get a new cable....

FireAnt · 03-22-2005, 06:56 AM

It is my sks side right at the 9 pin that developed the shorts. The seller from HK said he will send me a new cable and seems very nice. I would really just like this one to work now! I can't stand the wait and I've cut it apart and ready to solder it up. Can anyone help!
Thanks,
Mike

Yeah,
I have a meter and will try to fill in the blanks for what I can. I was missing about 4 wires it seamed like and was affraid some were reading wrong because of being shorted out. New screen so I hesitate to guess and accidently place the 5 volt+ usb wire to a RGB input by accident.

This is a good one

I do not have an easy answer.... sorry mate. I have replaced an ps2 connection, I very carefull (like you have already started) mapped out the wires to the connector and tested it with my fingers crossed.

My very real suggestion (cause your stuff is more expesive than the touch pad I was playing with) is to wait for the replacement cable and avoid causing damage to any of your parts.

FireAnt · 03-27-2005, 11:27 AM

I've tried hooking up the ones I know and it still does not work.

TruckinMP3 · 03-27-2005, 12:25 PM

Bummer, will you be able to get a replacement cable?

FireAnt · 03-27-2005, 06:10 PM

yep, a new replacement cable is supposed to be on it's way by airmail. 7 to 14 days maybe. The waiting is killing me. I really wanted to get used to the touch screen and see if I could use it with out a physical keyboard in my car. At least I have time to import all of my music cd into i-tunes while waiting. And the Mac Mini looks good on a 100" screen from my sharp lcd projector!

I know waiting sucks

my project has been changing/evolving ofer more than 5 years now.

Mike, here it is:

Shield-Grounds ------------------------Power connector, audio, video connectors ground

Please, notice you had 8 blue to red 14. My test shows it goes to 13! And 9 blue goes to red 14.
I didn't check all the rest though.

There is no green 4 because it's +5 V.

I have created html table, but couldn't post it here. Here it is http://www.astaltsev.com/CarPC/liliput_cable.htm

Good luck!

can you buy replacement cables from anywhere? Im planning to butcher mine but ide like a spare for when its out of the car or if i sell it.

Well, I checked several times (even though it was 2AM). Why is that there "has to be a +5V"? Do you know what voltage touchscreen controller uses? And BTW it is now part of one big PCB, not a separate board (I think in previous Liliput it was on a separate board).
Yes, two green 1s, because it's ground. Nobody complains about two +12Vs

Notice - THERE IS NO shield connection between USB, VGA and monitor 14 din connectos. I don't know why, but there isn't.
I first noticed this when I was powering my Lilliput from separate power supply - not from PC's 12V. If you don't connect USB cable to PC - image is flickering. Bad ground.
Do you have such cable? Please, check it. I also want to make my own cable, because this one doesn't look solid. So I am interested in truth of the pinout also

I don't have Liliput here with me now, but I just remembered taht 10,11 and shield on 14 pin din are all together.
So it's not "duplicate ground for usb" - just one more ground TO Liliput that is common with USB ground.

Touchscreen works from 12V, because when monitor is connected to 12V and USB, but turned off by power button (sits in standby mode) - when you turn monitor back on - Windows finds a new USB device.
