After installing several devices based with the ADM2587E transceiver on the same bus, we have noticed that some transceivers gets damaged (not all of them).
The failure mode is that, when working as a driver, the RS485 signal is not bipolar, but a 0 to 3.3V signal (as you can see on the attached picture. When working as receiver, everything is Ok.
I'm attaching as well the schematic of the comms section.
Do you have any idea what is happening there?
