when our system run in the field, which is damaged, ADM2484E communication isn't normal, system return back , we find A/B differential signal is different with normal things, pls help analyze, enclosed is SCH,normal wave and un-normal wave.
When you say that your system is damaged what do you mean?
For example, is the system damaged due to a high voltage transient?
Have you confirmed that all of the components in the attached schematic are operational after the 'system damage'? Are any of the components damaged? (....the SMA10CAT TVS, the R44-R48, the L8-L9)
