eWon Flexy I/O Card Behavior

I have an eWon Flexy unit that has 4-20 mA signals for 3 of the 4 I/O positions are bouncing from 6,500-13,000 over and over again. What would cause this?


It could be some reflections on the line that is causing the values to jump.

Have you connected an oscilloscope to measure the vaules?
