    Please go to setup - serial port and configure COM port number and baud rate (115200). 3. now you should be able to communicate with the E412. Test the „v“ command. - print the version minicom (Raspberry Pi) We have tested this terminal application (minicom) on the Raspberry Pi. Please configure it for 115200 baud and 8/N/1.
  • Page 24 7. reboot the Raspberry Pi so that the changes can take effect 8. the Raspberry may also be used to read the EDID of the E412, if the HDMI out of the Raspberry Pi is connected to the HDMI input of the E412. Please make sure that the EDID is enabled in the config.txt file.
