I can't figure out how this rotary encoder works. What's the Vcc and GND?

The technical sheet is attached here but it does not say anything about how to wire it

The rotary switch could be called a HEX position 4P16T rotary encoder with negative logic where 0= open cct = all "1's" and the wipers connected to Gnd.
