Use Differential Devices for Analog and Encoder Signals A differential device receives or sends one signal over two wires (typically a shielded twisted pair). The input/output voltage at the second terminal is the inverse of the first. Information is received/sent as the difference between the two voltages.

The advantages of using differential signals are: 

1. A differential signal is less susceptible to electromagnetic noise. Static or other interference affects both of the twisted-pair wires equally, so the difference between the normal and inverted voltage remains unchanged. A differential signal can be transmitted over a much longer distance or in a much noisier environment than a single-ended one. 

2. MMC hardware circuitry can detect signal loss from an encoder if the signal is differential. The application program can be set to shut down the application if such an error is detected.
