REVELTRONICS

hi im just wondering after i plug in the box and display and then plug in computer so i can setup the settings and display, it shows nothing.
the intro comes up for a second then goes away them the trip daily counter comes on for a few seconds and turns off, then it goes black screen.
is there a way it will show me the display i want to use in the car, for example i want to use user 2 setup on display and i put in all the topics i want for user 2 like boost oil temp and pressure etc, then i want to see it on the screen to double check if i like that design but it will not display
any info would be good
thanks

You need to have ignition switch in middle position to wake up UTCOMP (it has to be +12V on pin A23)

cheers thanks for that info very helpful.
