How does RS-422 work?
The specification itself does not imply buffering or include buffering, it is just a fast serial specification - http://en.wikipedia.org/wiki/RS-422 However, it is possible to buffer the input and output on the specification, as the followi... Read More »

RS422 uses differential signaling to greatly improve its rejection of noise. TTL signals are either 0V or 5V (not differential). I suppose if your cable from your motor encoder to the motor controller was lengthy, you might want to convert ...
