Thread: Nervous Buyer - Can anyone confirm these connections!?!

I'm pretty definite about getting a Biscuit PC from Advantech now and I'm looking for a few opinions on if I've got these connections right. The LCD panel is a Sharp LQ10DS05 with a 40-pin Hirose connector on the back.

The Biscuit PC is the PCM-5822 which has a 44-pin mini EIDE connector. While searching for info on the LCD panel, I found it was mentioned in the supported LCDs of the PCM-4825. Although it was specifically named, I didn't want to buy a machine with a low spec (even for a Biscuit PC!). So I think that the 5822 supports it, the LCD Chipset is slightly different but most of the pinouts are there just in different places. Anyway, here are the details so far (excuse the layout!):

I've put my guess after the '>' in the left column for where the pin goes on the LCD panel. I hope it doesn't matter that the 'TST;R/L' and 'TST;U/D' aren't connected, whatever they are!

If anyone could have a quick check and offer their advice it would be great before I go out and buy something and find it all doesn't work! I've been told that it's best not to wire all grounds together to avoid interference but go to separate connections. I just want to make sure before I spend a fair amount on a custom made cable!

Also, I've still got the inverter for the panel from the Dell Laptop where it came from. It has lots of numbers but nothing that looks like a product code, it has dell all over it. It takes current from a 10-pin ribbon cable, is it worth using this, or just buying another inverter?

Thanks for taking the time to read this long post!
