Help for a new EMC user

[Tim Goldstein <tgoldstein-at-mlh-services.com>]

Hello All,

I have been trying to help a new user get going with EMC. He used my setup
script and on RedHat 5.2. Building of the RT kernel seemed to go fine and
the system seems to be booting into RT Linux just fine. He is using the June
2000 version of EMC and it also seems to install just fine. I had given him
some run and ini files that worked fine on 2 computers I had tested on.
Below is the messages he has sent to me and my replies. We seem to be stuck
now that starts with " Application initialization failed: no display name
and no $DISPLAY"

Any help would be appreciated.

  I didn't express myself very well, the error was in each axis not just X.
I changed them all and got rid of those errors, but it still has the display
name and all the stuff that followed that as an error. Still doesn't crash
though!

Try going into the .ini file and changing the value of the parameters:
MIN_LIMIT_SWITCH_POLARITY =	1
MAX_LIMIT_SWITCH_POLARITY =	1
The choices are 0 or 1. Just make it the opposite of what you have now. I
think I would start with just the X axis as the error message is only
indicating that one, but you may need to try it on all axis's.

Let me know if it helps.
