Interfacing of Psychopy with Mitsar SmartBCI

I am working in Mitsar SmartBCI24 model 21 channel EEG system. My work is in designing BCI Paradigms. I had designed the paradigms using Psychopy coder. Now I want to interface the designed BCI paradigm (SSVEP) with the Mitsar SmartBCI application, where I need to mark annotations automatically while recording the signal.

Anyone guide me how to interface it?
