RE: EPICS support for PI C-862 Mercury motor controller

["Isenegger Andreas" <andreas.isenegger@psi.ch>]

Hello Joe,

Your directions showed me where to look for the substitution files. That
helped me to get the communication working, but the stage didn't move.
Then, after fiddling for hours with the parameters and reading the
source code, I got it moving flawlessly. Hence I can state that the
EPICS driver for the C-862 also works for the C-863 PI Mercury
controller.

Thanks for your help.
Regards,
Andy

Hi Isenegger,

There are example setup files in <top>/iocBoot/iocWithAsyn of
the motorRecord distribution. st.cmd.Vx has examples of the
configuration calls for the C-862
  	PIC862Setup() and PIC862Config()
That is where the connection to the asyn port is made.

I would recommend looking at the motor.substitutions file
(also in that directory) for a nice template for loading
motor records.

Your asyn port setup looks right to me.
