Connection examples
Connection example 1: HTL encoder, bipolar, with reference signal
Figure 7-8 Connection example 1: HTL encoder, bipolar, with reference signal
Signal cables must be twisted in pairs in order to improve resistance to induced interference.
Connection example 2: HTL encoder, unipolar, with reference signal

Because the physical transmission properties are more robust, the bipolar connection
should always be used. The unipolar connection should only be used if the encoder type
does not output push-pull signals.
