•
Logical 1 is recognized if a positive differential voltage is applied from
SM+ to SM-.
•
Logical 0 is recognized if a negative differential voltage is applied from
SM+ to SM-.
•
To increase noise immunity, the differential voltage range should be at
least 2.5 volts. The greater the differential voltage range, the higher
the operational reliability against interference.
