Lilliput Proprietary Cables Pinout
Alright, here’s the deal, after being extremely disappointed in every source (or lack thereof) to have a nice pinout of the Lilliput connectors, I decided to make my own. Apparently different models have different connectors to the screen, but all have the VGA / USB to 9 pin connectors. Anyway, this is the proprietary connector I’ve got, and what the pinout uses.
Lilliput Proprietary Connector
Now, if you don’t have the same proprietary connecter as I do, you’ll have to test it out yourself(easy if you have a multimeter and 15 minutes). So without further ado, here’s my pinout of the proprietary connector and all that stuff that comes with it.
Connectors
Some comments on the pinout. First off, I didn’t label colors of wires inside, because it could be different for different models or years of make, so rather be safe then sorry and just figure out the colors yourself. Anyway, everything is labeled with the “From A to B” mentality, if you’re any sort of E.E. you will probably have the USB and at least some of the VGA pins memorized. This helped me because obviously the first pin of a male USB is ground, which was easy to find its pin on the Female 9 pin. From there it’s easy to see the middle row of the Female 9 is in two pairs, the D- and D+ respectively on the left, and the ground and 5v respectively on the right. Leaving the other 5 pins as R G B and both Syncs for the VGA. Now what really got me transitioning to the Male 9 pin was the lack of that ground 5v pair. If the Lilliput connector is 14 pins, and the incoming voltage is 12v, where is that 5v line coming from? It’s easy to see every pin of the 14 is accounted for with something else, so where is that 5v? Then it hit me, USB devices are generally powered by the 5v line, but since this screen is powered externally, there is no need for that 5v line to be connected to anything. So there you have it, 14 pin Lilliput proprietary connector to the Male 9 pin, 2 Videos, Audio, and power line, as well as the 9 pin connector to VGA and USB. If I made any mistakes, please let me know. Enjoy the pinout diagram!
