SV: [AVR-Chat] communication b/n many controllers

Hi Mago You may take a look at Modbus http://www.modbus.org/specs.php Download 'Modbus Protocol specification' and 'Modbus Serial Line Protocol and Implementation Guide V1.02' This will give you an idea on how to do 1 master and many slaves over RS485 lines, by only addressing the slaves.

My question is that is this method reliable? Is there no effect of the 17 others connected to the line when one is communicating to the master? any idea? regards mago [Non-text portions of this message have been removed]
