Re: [Emc-users] Mb2hal 2.9?

Bookworm has /dev/ttyUSB "locked"
File icon has red cross

stat /dev/ttyUSB0

Check if it contain:

Gid: ( 20/ dialout)

Then:

sudo usermod -a -G dialout $USER

Thanks Gene, 

I'm not sure that, bug is completely relevant to my issue. As my Mb2hal 
config never used serial/by-id. It has always used /dev/ttyUSB0 to address 
the RS485 device. Maybe serial by id might be a better way to address the 
specific serial port used, but I am not even sure if it is even be supported
by Mb2hal or exactly how to set it up that way (none of the example Mb2hal 
configurations use it.) And even if it were possible, I'm not sure if I 
still would have had the permission problems and I would have also had to 
fix the udev bug first. Changing the permission is all I needed to do to get
this working as it was before.

Your debian 12 install has the udev bug I sent you a link to the fix 
already. It restores the missing two lines that setup the serial/by-id stuff
for usb.

Re: [Emc-users] MESA card suggestions

[zz912]

Hello Alan,

You can start with one 7i96s.

Then you can add one 7i84.

Then you can add 7i74 for 8 pieces 7i84.

Or you can start with 7i96s + 7i74 + (2 to 9) * 7i84 imidietaly.

I dont like sharing inputs. For control panel you can use input matrix.

The 7i96S is available (unlike the 7i76E, which would be another good
choice) but it is a little short of IO, having one input fewer than
you require. (And maybe you want a probe too? and some external
alarms, coolant level sensing...(
You can easily add extra IO with a smart-serial card such as the 7i84.
(Though there are 17 unprotected GPIO pins on the expansion connector
too, but using those as bare pins is something I would only suggest to
the electronically confident)
