Welcome to LinuxCNC.org

Hello!

I use 2x4i65 with 2x7i33TA and 2x7i37TA. Now I would use the 7i73 via 7i44.
Is it possible to combine these cards together? Is there a firmware to access the 7i73?
I have seen it is possible with a 7i25 but not with a 7i65.

After your OK, I will buy these Cards.

Thanks and have a nice day,
Thomas

It should be possible but would require new firmware.
What current firmware are you using?

Hi!

I use the firmware SVST8_4.BIT comes with 2.5.

Thanks a lot,
Thomas

OK do you current have both 7I33s connected to one 4I65?
and do you use any stepgens?

I am asking so I can figure out what is the least disruptive way to add the sserial support to your current boards (the 4I65 has a fairly small FPGA so I am limited in what I can cram into it)

If you are using a 7I33 per 4I65 and no stepgens then a SVSS4_8 config on one or both cards (4 servo + 8 sserial channels) is probably a workable solution

I have 1x7i33 and 1x7i37 on each 4i65.

I have not stepgens configured on the boards only the I/Os(7i37) are in use.

My favorite configuration:

4i65 0: 7i33 - 7i44 - 7i37
4i65 1: 7i33 - x - 7I37

OK so theres a pinout for this config (SVSS4_8) with one small change: its 7I33,7I37,7I44.
That is, the smart serial is on the last connector. I'll built s 4I65 version of this config sometime today or tommorow

ok 4i65 svss4_8 is available from freeby.mesanet.com/4i65_svss4_8.zip

Hi!

Thanks a lot. Now I order the 7i44 and 2x 7i73.

Have a nice day,
Thomas

Hello!

After a long time I tried the new Firmware, but now I have some troubles.

The output from dmesg:

Is there anywhere sample configuration with the 7i73.

Have a nice evening,

Oops sorry, thats my fault.
I'll make a new bitfile with that fixed
but it may have to wait till Monday if
I'm not around work anytime this weekend.
