#82282 - distance problem Responding to: ???'s previous message |
All nodes are connected to the GND, but because my 232/485 converter has no GND output, I connected to the common GND of the bus directly to the PC's RS232 GND. I also tried it as it was no connected to any GND at PC side.
Does excessive environmental noise cause such a situation I faced with. If yes, is there any thing I can do for this except changing the whole bus with a shielded one? Rustu |
