MicroController discerns addresses in RS 485 systems - 11/08/01 EDN Design Ideas
/ (added 1/05) One of the many benefits of using the RS-485 data-interface
system, unlike the RS-232 system, is its ability to implement multidrop networks. Such
networks usually carry 9-bit data words, in which the ninth (parity) bit identifies
each word as address ... |
