Hello friends,

Although this is not 8052 related, but I feel it might help everybody.

I am still considering myself a novice in the RS-485 world, although I have done some projects using them. Most of them are of experimental nature.

In a real world application, how does a faulty device is isolated so that it will free the bus? The fault could be (but not limited to) say a short circuit of the output driver. What are the precautions / protections to take while implementing a large RS-485 based network?
