Hi, my name is David.

   I want to communicate an ADuC7060 with a PC, using the ADM2582E (RS-485 full-duplex).  The schematic is showed below:


The problem is that the transmission from the PC to the ADuC7060 is right, but from the ADuC7060 to the PC is null, and I don´t know why.

I have changed the ADM2582E to the ADM489ARZ and it does work fine.

Thanks in advance.
