i know i had that issue with those miners in the past, just gooling helped me
The control board on the Alchemist Alcheminer 256 seems to be a proprietary board, which does not have USB, and since the ip address is not getting assigned (shows up in the LCD window as 0.0.0.0 ) I can't get it. The googling I have done seems to indicate that one of the two pin headers on the board are for a console TTY, but without knowing for sure and pin-out information.... I really don't know what I'm doing. I would hate to actually damage the board.
Thanks for replying !
