    klaute got a reaction from lanefu in Monitor multiple OPI   
    Hi,
     
    a few months ago I have build a USB to UART "multiplexer" device, to monitor my multiple Orange Pi PC's using only one USB connection to a separate Host [1].
     
    You can connect up to 8 hosts to the device simultaneous. And you can switch between the different inputs.
    Only one USB connection is needed to your host you want to use as master.
    A commandline tool is available to control the device.
     
    Its also possible to send data through the device to the connected hosts. It works like a normal USB to serial adapter.
    It is not possible to read the incoming data from all connected hosts simultaneous.
     
    I am use it to log the boot process of my cluster nodes [2].
     
    Maybe someone is interested. It is OpenSource and OpenHardware [3].
