According to the datasheet here it appears that you need to connect both pins (DIN and BIN) to the data output from the rpi.

The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis [SIC!] of 24bit data, if DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.
