I tried to install tigervnc and it destroyed my system after logingb in with the correct password it just keeps taking me back to the login.So I reinstalled linuxcnc und updated it.now I can not connect to the mesa Ethernet card 7i76Ei get the following error. 

 

Did I do something wrong during installation?

I would make some changes in the hal file.

Change:

setp hm2_7i76e.0.dpll.01.timer-us -50

to:

setp hm2_7i76e.0.dpll.01.timer-us -200

and change all joint PID "P" terms to 666

How did this work out? I also have a 7i76e and are sick on my USB-RS485 converter that resets itself sometimes in the middle of a program... Might be interference from my HY VFD. Want something more robust.

pktUART bin file is not available from MESA. Do not really know if this is the way to go or if there are something simpler?

You are welcomed, always, and welcome to the "dark side" !
Used them once, worked MUCH better than advertised, got unbelievably good support from PCW, used them ever since, a lot.

Thanks for confirming this, I haven't used multiple Mesa boards at once before. What a great system.

Yes, you can use 7i76E with 7i84 with a cut in half LAN cable (see manual for wiring), and 7i85 with a IDC26 to DB25 cable (available on Mesa stores and even some older PC's have them, look for a parallel port on the back slots). BTW, 2 of 7i85 could be used as 7i76E has two IDC26 headers, or similar boards, and you can add more 7i84 or 7i79 or 7i71 or 7i72 to 7i85.
