SC18IM700 not Responding Correctly

Question asked by Graeme Anderson on Apr 10, 2020


I am using the SC18IM700 and after powering up I am not getting the "OK".

However I am getting the a long chain (maybe up to 10x) "O" and then a long chain of "T" instead.


The documentation does not state what this behaviour means.


I have checked this output on both the PC serial terminal and on a decoding oscilloscope.

Signals are clean and not cross coupling.


Any ideas?
