Mesa: HD or DB connectors? Which one to use?

Hi,

I'm looking at getting some Mesa cars for controlling my cnc machine. I would like to go for ethernet based (like 7i92, 7i80) with stepper/dir cards (like 7i76) and encoders interfaces (like 7i85S). These cards are available in DB and HD variants. However, I'm not sure what the pros and cons are of DB and HD? Could anybody point that out?

The distances between the cards will be small (because of the ethernet). So I don't think shielded cable is necessary.

I got the impression that for DB25 daughter cards more variety is available????

Thanks in advance!

hi
you need to dicide on mashine bahavior
what kind of mashine is it
what are the extras you plan
as for a standard mashine the low cost ethernet 7i92 and a standard BOB is most used
then a 7i96 standard is to be considerd for lathe and 4th axis mill
at 5 axis it is a 7i76e to be choosen

and beond it is up to the mashine

Thank you for your replies. It seems the difference between HD and DB connector is more a personal preference.

I went ahead and ordered a 7i76E and a 7i85S today. These cards were easily available and fit the purpose (at least that's what I think now ). Hopefully the cards are here by the end of the week so I can start playing around with it.
