8.Three terminal block (used to connect the 220V power cable)

9.5V Flat cable ( connect receiving or hub card to module,module to module, use for signal transfer)

10.5V power cable( connect power supply to module, use for module to module’s power transfer)

11.Power supply ( use to transfer the power voltage which module acceptable. Usually from 220v change to 5v )
