Emax

Could it come from the PSU going down? I had the PSU fixed last year, maybe something was done wrong

I know on RS-422 devices I used to install for Point of Sale, that in rare installations we had to use line conditioners with "ground guard" that negated difference potential across the grounds.  Once we did that the RS-422 worked perfectly. But those were expensive.... although there is testing that can be done to see if there is a voltage on the ground that shouldn't be there... usually this is AC voltage present.
