Have received a problem at use ADM2484E - the starting bit turns out with "step". The circuit drawing and signal photo in the appendix. In the photo:
- blue signal (3) - transmission enable - pin 5 DE ADM2484E
- green (2) - TxD signal on 6 pin of ADM2484E
- yellow (1) - RS485 line signal (DATA+ pin 14 ADM2485E)
Thanks!
