For contact inputs, the remote signal rises when the contact switches from open to
closed and falls when the contact switches from closed to open. For open collector
signals, the remote signal rises when the collector signal (voltage level of the remote
terminal) goes from high to low and falls when the collector signal goes low to high.
You can reverse the above operations (see section 7.3 for details).
