Connection of absolute encoders with SSI interface and an \ optocoupler interface at CLK input

The following figure shows the electrical connection of an absolute encoder with SSI interface and an optocoupler at the CLK input to the module CD522. The encoder can optionally be powered through the 5-V-power-supply which is integrated in the CD522.
