Hi,
We are using SN65LBC184 in one of our device, currently we are facing some issue with the communication with our RS485 base device both master and slave we have design, On site we have observed RS485 (SN65LBC184) failure means communication failure issue. in above case some time Master RS485 gets damage or sometime slave RS485 gets damage.
Also we have found some RS485 ic having transmit junk character. Slave device gets proper data but at receiving side we receives some of the junk character.
What will be the issue??? Damage and junk RS485 is more concern for us...
