    I get an error that the serial port is wrong, I've tried both ports 3 and 5, but, I get the same message. JMRI is also sayng that the train cannot be found.

    When you program your Arduino on this computer, , what port do you see used there for that?
    Are you connecting thru a hub or direct to the computer.
    I simply swap the cable and it’s the same port, but I’m Mac user.

    When I originally programed DCC++ I was connected directly to my laptop (PC), the port that was assigned was 3. JMRI say's it's not recognizing 3, so, I went back and changed the port on the Arduino to 4, JMRI tells me it doesn't recognize 4. So, back to 3.The last message I received from the JMRI setup program was it does not recognize the loco. After spending all day Monday (Canadian Family Day) with two laptops one showing how to install JMRI (following along) and the other trying to install the program, I think I have given up, maybe, have to buy a name brand. Thanks for your help. CD

    Don’t give up! I’m not a windows person for 20 years now but Sounds like you got past the port issue when you went back to 3? . You did close the Arduino ide program, correct? Doesn’t windows hold the port if the program is open?

    Question, did you change DCC++ from internal to the other option in the in program settings? I had a similar issue on my both my Mac and then 3 months later on my RPI jmri until I realized it was still set to internal. At least the second time it only took me 20-30 minutes before I remembered to double check.

    But if you do, think about sprog. It’s very similar to DCC++
