#101135 - There is no such thing
Responding to: ???'s previous message
I am talking 4 wire RS485.
There is no such thing.

RS422 is 1 to 1 (like RS232).
Nope, the standard allow 10 (if I recall the number correctly) nodes.

Some may have ignored the standards and christened somethig "4 wire RS485", but that does not make it right.

"4 wire RS485" IS RS422
