external 5vdc supply



  • Hi every one
    Just a simple question
    I would to use an external 5 volts DC supply normally no ATX, PS_ON, i mean just + and -
    How should i connect it to the ethernet board?
    +5v source to the +5v Duet pin
    GND source to the GND Duet pin
    Can i let the PS_ON whit out connect it or should i do a bridge with + or gnd?
    Thanks



  • the ps_on is an outgoing signal to the power supply.
    if you dont have it leave it unconnected.

    you could also use a relay control to control the mains power to the main psu and turn it on and off with that functionality.



  • thank you dear @veti for your fast response
    Have nice day
