AD5755-1 SPI communication problem

I am trying to run AD5755-1 evaluation board using SPI communication via on-board J11 pin. 


I have a board supports SPI communication.


The board has SPI header (please check the attached image) but I don't know how to correctly connect SPI header and on-board J11 pin of AD5755-1 evaluation board.


As I know, 4-wire is needed for SPI communication, MOSI, MISO, SCK, and SS.


What pin of the on-board J11 should be connected to each wire? 


Also, I would appreciate it if you let me know the detail description for each pin of on-board J11 pin (DV_DD, DGND, SYNC, SCLK, SDIN, SDO, LDAC, etc.).
