Hello,

Beginner in this world, i'm on the testing bench in order to get everything working before doing my retrofit.

My goal as of today is to use a 7i96s with a 7i73. The 7i73 will mostly be used in order to get more I/O and 2 rotary encoder as lathe handwheel.
I've attached my HAL file.
Here is my issue:
When I start linuxcnc, everything is OK, 7i96s and 7i73 green LED are blinking properly.
In Halshow, I can see boths cards and I can add 7i73 I/O to my watchlist.

However, as soon as I set one input to 1 with Halshow, I got red LED (CR1  communications watchdog fault ).
How is it possible to have the cards communication correctly as they must identify each other but not working in order to set I/O.

I will continue my checks, starting with a new RJ45 cable but i wanted to know if someone encountered the same issue ?
Thank you in advance

Do you means set an output with halshow?

Is the output connected to anything?

This is not my printscreen but here:

I have the ability to "set" an output. My understanding was to be able to set output to high and check with my multimeter if it's to 5v or 0v. The output is not connected to anything yet, it was just to test some features of the board as I was not able to read an encoder value.

I set all outputs on a test setup true without issue:

 

What hardware mode do you have and what is the software revision of your 7I73?
( = parameter swrevision )

That's the same as my test setup and same SW revision.

Is anything connected to the 7I73 I/O connectors?

Sorry for late reply. I gave the information on discord but not here.

Was all my fault since the beginning ;(

I will try to explain in English but it's not my native language.
I did not correctly understood the pin number allocation. So I assume the first row was 1 to 20 and the second one 21 to 40.
Hence all my tests were wrong and I'm very lucky to not damaged the board.

I read the documentation several times and with a printscreen from another forum member whom is helping me a lot, I understood one row was for odd and one row was for even numbers.
Rookie mistake and waste of time for several users. Sorry for that.
Now everything is working

Thank you
