Connection example 2: HTL encoder, unipolar, with reference signal
Figure 9-15
Because the physical transmission media is more robust, the bipolar connection should always
1)
be used. The unipolar connection should only be used if the encoder type does not output
push-pull signals.
Figure 9-16
The photo above shows the wire jumpers for connecting unipolar HTL encoders with a reference
signal.
