Simply, what is a RS-422 line? Additionally, what does it do/is it used for?
In: Technology
Several answers explaining what it is. What is it used for? In my experience: Control and automation of factory equipment, scientific instruments, and other machines. Also, diagnosis and repair of more complex electronic equipment when other means of control have failed.
