Other Parts Discussed in Thread: SN65HVD72
Hi TI Expert,
in our simple point to point RS485 communication using your SN65HVD72, we are facing the same issue on R pin as reported here ((+) SN65HVD75: SN65HVD75: Output issue - Interface forum - Interface - TI E2E support forums)
We saw the topic was closed/moved to direct communication via mail.
Could you provide the final solution of the problem?
Just for your info: our schematic is really close to the one in the ticket, the connection is point to point, we run at 115200bps N81,
In our case the R pin goes down for 400ns (see the picture)
Many thanks
Federico
