Multiple Mesa 7I84 I/O board setup

Hello,
I'm getting more familiar with LinuxCNC and Mesa boards, converting a Biesse Rover 13s and have a 7I96s step and direction interface along with a 7I77 analog servo interface connected via the P1 expansion connector. I also have one 7I84 I/O board connected via the TB2 sserial and all is well, I can command the outputs etc. from halshow at all the boards but I need to connect two more 7I84s. I also have the 7I94T anything I/O Ethernet card but I'm using ethernet already on the 7I96S with 10.10.10.10. Should I reset the 7I94T IP to something other than .10 and use an ethernet switch or is there another way to use multiple sserial channels from the 7I96S?

By the way I really appreciate all the others that have gone before me and made this all possible! Thanks for the help!

This is doable, take a look at this thread:

You can use mesaflash to change the EEPROM IP address
(probably to 10.10.10.11)
 

Thanks PCW, was hoping to get your opinion before I did it. I will give it a go.

I get this error when I try and and read the device with mesaflash --addr 192.168.1.121 --device=ETHER --readhmid:
unsupported ethernet device 7i94t at 192.168.1.121 no ether board found

From what I've read is it could be that I need to update the mesaflash version, I currently have 3.4.9. Is there a clean way to update Mesaflash or should I remove it and install the latest version?

I would replace with the latest
(sudo make install will do this)

That took care of it!
 removed the existing mesaflash folder since git couldn't clone with an existing folder of the same name, did the sudo make install and was able to right away get the info from the board with mesaflash --device ethernet -addr 192.168.1.121.
Ran the mesaflash --device 7I94T --addr 192.168.1.121 --set ip=10.10.10.11 and I can ping both the 7I96S and the 7I94T through a switch.

Do I need to flash a particular .bin file for the 7I94T and the 7I84s?

Thanks!

Nevermind! I found the correct bin file in the 7I94T manual, 7i94t_ssd.bin. 

Just an FYI when i run pncconf with the Mesa Card 1 option I get an ValueError: Invalid literal for int() with base 10: 'EXPANSION+SERIAL'.

I will try and add the card info to the hal file, should be good practice. 

It looks like it's something with the pin file maybe when I try and choose Mesa Card 1. I did the mesaflash --readhmid and copied that to the PnCconf Input, removed the Expansion from the line: IO Connections for Expansion Serial 0..1 -> 7I94_0 and now I get a VauleError: invalid literal for int() with base 10: 'SSERIAL'

Is there something I'm missing? I did a compare of the successful 7I96S pin file and didn't spot any discrepancies.

Attached is a screenshot of the error and a text file of the 7I94T --readhmid
