Spark Switch Pro and PB terminal

  • The instructions says:

    Connect the PowerBox USB interface adapter or BlueCom adapter to the socket on the ignition switch marked DATA.
    A battery (max. voltage 8.4 V) must also be connected to the receiver socket.

    Run the PowerBox Terminal program on your PC, then follow the on-screen instructions.

    When I do that, all I get is a countdown from 5 to 0 and a short glimpse of "connection", then nothing.

    What should I seem nad why do I not see anything?
