Sinus signals require some precautions for noise immunity that may be a little more demanding
than conventional square wave encoders. Use of twisted pairs (possibly with individual shielding of
each pair) is recommended. Use one pair for sinus+ and sinus-, another pair for cosinus+ and
cosinus-, another pair for data+ data- of the absolute serial channel, another pair for clock+ and
clock- of absolute channel.
