Will check and report back. Machine is sitting at home...

I do not have access to a continuity tester.

I guess i can try this... I suppose it won't hurt?

I will get a volt meter... What pin should i use as ground? I tried
having a look at page 7 of the LPC data sheet but i didn't see a
ground pin...
