power expander

  • Hi

    i just un boxed my Brand New power expander, does not work, does not connect to terminal, using sbus futaba set to mode b, plug servo in to sbus receiver 8 and it works, unplug it , then plug sbus to rx1, servo into port 1 or misc , nothing happening, dead.

    plug in usb terminal, battery, and terminal into usb port on expander, program cant detect power expander.
