Pci or Ethernet motion control?

[Clive S]

I'm looking for the best option for the motion control cards and software. is there a performance benefit of a pci card over an Ethernet?

To me the Ethernet option looks neater (Mesa 7I76E) but is there more chance of interference on the cable?

I use a 5i25 pci card with the 7176 I think there are more examples of that than the 7i76E but although there is nothing wrong with the 7i76 if I was buying them again I might go the 7i76E route, you won't have a prob with he cable.

I take it that you know that both of them will take two mpg encoders and and spindle encoder.
