Greetings PCW and all;
I find I need a way to do a powerdown reset on the interface box of
one of my machines. And it needs to be separate from linuxcnc. That,
or some way to tickle the 7i76D to reset it before I start LinuxCNC
the second time because hal can't find spinout.
I am finding that little power bumps, not enough to do a full
powerdown reset, are killing the 5i25 to 7i76's serial com. Short of
rigging a 3rd hand switch on the shelf to toggle the interface power,
or getting out a stepladder to access the one on the rear of the
shelf, once the 7i76 has been bumped, the seriel port is dead until a
full, several seconds dark powerdown, there seems to be no other
recovery method that works.
Ideas anyone??? Or do I go get a switch plus socket and position it
where I can operate it from the front of the machine?
Thanks all.
Shucks, I was hoping there was a secret handshake I could put in a rapper
for linuxcnc that would tickle the right 5i25 bit(s) to do a full reset
on the 7i76D just before linuxcnc was started.
I would verify that your field an 5V power are OK at the 7I76 end.
I dont see any way a short power failure/glitch should get the system
into a unrecoverable state.
So I guess I'll have to stop at Lowes on my way home from the horsepistol
tomorrow, and get one of those combo switch and outlet gizmo's and a
handibox.
