5. Pin assignment of SUB-D-connectors
5.1. Sin/Cos inputs
Standard encoders with differential outputs can be connected directly to the corresponding pins
SIN+, SIN-, COS+, COS-, REF+, REF-. Where longer cables must be used, terminating resistors
between the non-inverted and the inverted signal of each channel may be of advantage.

With sensors using single-ended outputs, the sensor signals SIN, COS and REF are connected
to the corresponding input pins. The inverted inputs of the unit can be connected either to the
mean voltage output Vm (pin 8) of the unit or to a corresponding voltage reference of the sensor
itself
