#121824 - Why? Responding to: ???'s previous message |
I mean if the rs485 to rs232 convertor works why remove it and give yourself a pretty nasty design problem trying to connect an 8052 directly to a rs485 system?
As Rs485 uses differential signaling at upto 10 Mb/s I seriously doubt it can be done very easily, if at all. |
