Hi, i try to connect this arduino 1 by serial port 115200, 8n1, but the emf does not response, i send <POWERON>> just to test, but not work, any idea? |

Our engineer said even ch340 to ch340 also does not work as those are slave devices and only works with the driver. You need to connect the Rx/Tx of the arduino directly to the tx/rx of the emf390 cpu. |

Hello, thanks for your answer, arduino one has a usb port with a 2303 adapter similar to the ch340, but it does not communicate with the emf, also try with an arduino due that has a native usb port, but it does not either, just get me to communicate with the computer. |

Hi mserdag, the port is USB. You need to connect the RX/TX of the arduino to the TX/RX directly to CPU or input pin CH340 of the EMF in order to communicate via uart. |
