Is RS422 or RS485 better?
Hi Robert...
Quoting MAXIM, "The great thing about standards is there are so many to choose from." 
Selecting and Using RS-232, RS-422, and RS-485 Serial Data Standards by Maxim: Mixed-signal and digital signal processing ICs | Analog Devices
RS-485 meets all the RS-422 specifications and I always thought that RS-422 was just an early version that is seldom used. Anyone know of RS-422 specific applications?
