Not only do HVD and SE or LVD not work together but if you connect them
and power up both ends you are almost certainly going to damage the
hardware somehow. I'm not certain just where you look for the smoke and
flames and it's not something you want to learn by experience!
Repairs/replacements are EXPENSIVE!!!!

Using the same connectors for the different flavors (SE, LVD, & HVD) was
one of those REALLY BAD ideas! There's always someone who will
thoughtlessly plug one into the other; I've even seen an SE do it!

Differential is great when you need a long cable run but it DOES NOT MIX
with SE. LVD is newer than HVD and I belive that it will mix with SE
but I'm not sure it's a good idea.
