Hello.
I have question, can i connect 7i49 via 7i92 card ?
Thank you.

I'll take a guess as to no.
With 7i92 being of the DB25 variety card and the 7i49 being of the 50 pin variety.
I'd guess these would be the cards to mate with the 7i49

Physically, yes. Using either a home-made cable or store.mesanet.com/index.php?route=produc...74_80&product_id=285 but it might not work.
However the 7i49 needs more IO pins than the 7i92 has, so even with a compatible firmware you would lose some functionality.
The 7i93 would be a better bet.

What is your application?

the 7i92 is mainly for upgrating PARPORT systems to ETH
the 7i93 is for the "old" mesa fpga stuff 50pin to get to the ETH benefits

As AnnoyingMutt & Andy have said, a 7I80HD or 7I93 are the best bet.
It might make some kind of sense if you already had a 7I92 and didn't mind making a custom cable.
You would need to get by with 17 vs 23 pins (assuming you did not want to steal from the second 7I92 connector)
its possible to do this by sacrificing 3 analog outs (6 pins) Whether this is a good compromise or not is up to you.

Sorry to short question.
I have old 4 axis cnc machine, on machine installed resolver on motor and linear resolver.
How I can receive a position to linuxcnc ?
I have 7i49 and 7i92 now, 7i49 in pdf connect via spi interface, I read pdf 7i92 he can support Spi interface. I check firmwares to 7i92 don’t see Spi pins.
If 7i49 can work with my resolver, I buy additional card. If not I move to optical position feedback system.
Sorry write from phone.
Thank you for your answers.

As mentioned before you would be better off with a 50 pin FPGA card for use with the 7I49.
The SPI interface is hidden in the resolver firmware on the FPGA card so you
just need firmware that supports the resolver interface ( usually has RM in the bitfile
name like "7i80hd_16_rmsvss6_8.bit" )
What type of resolvers do you have? It would be good to verify that they will work
with the 7I49 before going further in that direction.

The 7i49 definitely works, and works well. Both my mill and my lathe rely on the 7i49 for position feedback.

Thank you, I order 7i93 & 7i37ta
.
In manual text talk about firmware for 7i49 I download bit files from Mesa site & don’t see this firmware maybe anybody have compiled bit file ?
