Need help connecting Digital Drivers

Hi,

I am just getting started with building a CNC router machine for the first time and therefore have a big learning curve ahead.
I got stepper motors and drivers kits for Christmas. The drivers are DM556S (from Stepperonline) and I would like to use LinuxCNC.
I am not 100% sure how to connect them. Can you tell me if each of the following setup would work.

1) Regular parallel port —> MESA 7175 Breakout/FPGAprotection card —> DM556S drivers.
2) MESA 5I25 Superport FPGA —> MESA 7I76 Daughtercard —> DM556S drivers.
3) MESA 7I96 Ethernet interfaced Step&Dir plus I/O —> DM556S Drivers

If you prefer one of these setup over the others or if you have other recommendations, please let me know.

Thank you in advance for your help.

7i92M => 7i76 => step/dir--->drivrs

That would be my recommendation. There are many other options of course.

Thank you for your reply/advice, very appreciated.

I do recommend 7i76E to avoid the 7i92 Mesa Card.

I do build my machines with that card and have them in the electric department, and a Ethernet connection to to the PC, that way I only need one PC to control my machines. (I never use them ll at the same time)

Thank you Norbert.

I am not sure that I understand well the difference between the two boards, other than the number of I/Os.

I was under the impression that I could install either of these boards in the control box, wire them directly to the stepper drivers (same way for both board) and also connect them to the PC through the ethernet port (same way for both board). If that is not the case, can you explain what the difference is?

Thank you.

with the 7i92 you still need a ribbon cable or db25 cable to connect to the breakout card.

the 7i76 and 7i96 are both combined so only ethernet is used.

OK, I will go with the 7i76E.
Thank you again for your time and advice.
