  • When installing the screen, be careful not to plug or unplug it while powered on and pay attention to the direction of the screen cable to avoid damage.
  • When installing the fan, pay attention to the current and voltage specifications of the fan to avoid damage.
  • The FLY host computer can only use the middle RS232 interface, FAN port and FPC screen interface!!!
  • The G2T host computers that can be used in the FLY host computer are PI V2, C8, PRO X10
  • Gemini series and PI V1 cannot be used

Installing G2T​

  • Below is a reference
  • Reference wiring

Using the Onboard RS232 Connection Tool Version Method​

  • After the FLY host computer is updated with the latest system, you need to access host computer's IP+:9999

  • The FLY host computer can only use the middle RS232 interface, FAN port and FPC screen interface!!!

  • Find UART1 in the system settings and save and restart

  • Below is the reference configuration
