makes sense except i can't get a firmware option of 7i76_7i77. it offers me
7i76x2
7i76x2-with one 7i76
7i77_7i76
7i77x2
7i77x2-with one 7i77
G540x2
prob_rfx2
should i try 7i77_7i76 and try to modify that I also have a 7i64 on the 7i77 that might complicate that although i suppose i can put that onto the 7i76e

You would use the 7I77_7I76
You will probably need to renumber the 7I77/7I76 sserial channels since they
are in card order (the 7I76E will have channels 0 (7I76 field I/O) and 1 (expansion)
and the 7I77 will have channels 2,3,4 (field I/O, analog, and expansion)

ok. i figured out how to pncconfigure a 7i76e and made a configuration so see if it would connect. when i try to open it, it comes up with error
Can't find module 'hm2_eth' in /usr/realtime-3.4-9-rtai-686-pae/modules/linuxcnc
i looked in that location and that file or any file for eth is in there, so any idea where i can down load and install that file?

Im trying to reflash my 7i76e and when i try to
cd to ~/configs/hostmot2/
it comes up with either 'no such file' or 'too many arugments'
i have tried being more and less specific to location and it doesn't help. I can't ever cd to /home/ or any file string between there and the hostmot2

if you unzipped 7i76e.zip in your home directory, the bit files would be in
~/7i76e/configs/hostmot2
~/7i76e/configs/hostmot2

i managed to reflash it. way back on page 2 of this post you told me how to reflash my 5i25 and as an example you said
cd to ~/xxx/xxx/
and i took that to litteral. it doesn't work with the 'to' in there it needs to be just cd ~/xxx/xxx
stupid things i need to learn. It waists alot of time.
now i just have to see how that helps me set up the 7i76e. at least i have made it this far, now i can actualy see the 7i76e now i can plug the 7i77 into the 7i76e with the 7i64 into the 7i77 and see if i can access them all. might be a few more weeks at this pace.

does any one know what this code line 'hm2_7i76e.0.7i77.1.7i64.0.1.-00output should look like to work with a 7i64 connected to tb6 on a 7i77 connected to expansion port1 on a 7i76e

The easiest way to find the device names is to launch a minimal
LinuxCNC configuration and then run:
halcmd show pin hm2
from a command line
I would expect the 7i64 names to be something like
hm2_7i76e.0.7i64.0.4.something

halcmd show pin hm2

hm2_7i76e.0.7i64.0.4.something

I don’t know you could do that. That makes a lot of sense. Up to now I’ve been doing my pnc with pins on each card so I could see the routing. In the morning I will make one that only uses the 7i76e and see how that goes. I already left the shop for today. I figured I pulled enough hair out for one day. Thanks.

I was hopeful of this halcmd show pin hm2 working, and it does, but it only seems to show what the hal file says and since my hal file is wrong and needs to be modified, because pnc.config doesn't have the options that i need for the card configuration that I have, it doesn't help me. I need to figure out the line code layout to access each board in the string.
eg. '7i76e.0.7i77.0.1.7i64.0.2
Peter form Mesa said in an email '(the 7I76E will have channels 0 (7I76 field I/O) and 1 (expansion)
and the 7I77 will have channels 2,3,4 (field I/O, analog, and expansion)'
I guess what I really need to figure this out is the numbers after the card name in the address line (.0. or .0.1.) what is the first digit and what is the second digit. I'm thinking now that .0. is card one channel one .0.1. is card one channel two .1.2. is card two channel three .2.3. would be card three channel four.
Is this correct or am I way off here.
