7i92

Hi ,

Does anyone perhaps have Sample configuration files for the 7i92, with 7i77x2?
First time for me to play with this, but I have built alot of 6i25-7i77's, so I'm sure a sample .hal, & .ini file will set me off to success.
(Or even the lines that I need to add to my files, or Documentation where I can find these secrets )

Thanks for the help in advance.

a 7i92 with 7i77 configuration will be almost identical to a configuration with a 5I25 except
for the following:

Card name is changed (so pin/parameter names change)
Driver is different (hm2_eth instead of hm2_pci)
The driver needs the card IP address in the config line

The driver manual page (man hm2_eth) has the setup information

freeby.mesanet.com/7i92step.zip

Is an example step/dir config file set for the 7I92

Note that a big unmentioned elephant in the room is that you need to run
hm2_eth with the uspace version of linuxcnc under Preempt-RT
not RTAI

Thank you Peter,

I appreciate your help

Hi Peter,

I have tried your instructions, but no success. Please forgive me, but my knowledge of computers in general is very limited.

Could you please instruct me line by line for the 7i92. Eg. (my lines=)
loadrt hm2_eth config=" num_encoders=6 num_pwmgens=0 num_stepgens=0 sserial_port_0=000xxx"


Etc. What other lines do I require Making it different from 6i25? I changed all 5i25 in Hal file to 7i92, etc.

Please provide me with a sample configuration.

Please see attached the current test ini and hal files we are trying to test with.
Please assist us and advise where we are going wrong.

Please note that we have completed a mesaflash successfully with the 7i92_7i77x2.bit file.

is a known working example file set (using 10.10.10.10 7i92 IP address )

one problem with your sample is you loadrt the driver twice

Hi Peter,

Thank you,
This seems like the .hal file. What should the .ini commands look like?

I have the following in my .ini file:
[HOSTMOT2]
# **** This is for info only ****
# DRIVER0=hm2_eth
# BOARD0=5i25

I tried the following in my ini file:

[HOSTMOT2]
# **** This is for info only ****
DRIVER=hm2_eth
BOARD=7i92

but when trying to start linuxcnc, error is [HOSTMOT2]CONFIG not found
What should I put in CONFIG?

I have now also tried this in my ini file:

[HOSTMOT2]
DRIVER=hm2_7i92
BOARD=7i92
CONFIG=""

But I don't have a clue. I'm hitting in the air, not having proper documentation/reference to work from, I don't know what I'm doing here.
