M800Ex can save up to 10 patterns for projection mapping. If user wants to apply mulitple pattern in one project, user needs to use RS232 command to set time duration for each pattern. When execute RS232 command, user will apply different patterns to the projection mapping with different display time on the projecton object. The patterns will be switched seamlessly without black out or noise on the screen. User needs to take the transition time into time calculation because different pattern may have different loading time.
