3.2 While travelling with the OBU
While travelling, the OBU display content may vary, depending on where the vehicle is
driving, if problems occur or information is published by Satellic. The OBU records
exactly the road you are driving on. Contrary to GPS devices, the verification of the exact
travelled route may take a while. That is why the display is updated with a slight delay.
3.2.1 OBU Display
I. Default Screen
A default screen is displayed per default while travelling with the OBU unless a special
(overlaying) screen with additional information appears. The default screen is not
scrollable and not configurable by the user. The default screen has three different
operational modes:
(1) Inside Belgium –Toll > 0
(2) Inside Belgium –Toll = 0
(3) Outside Belgium –Toll-free
Default screen Toll > 0
The following screen is used on toll roads:
•Toll/Unit or Toll/km: this is the basic price per kilometre (normal case in
Belgium) or the basic price per unit (e.g. for toll tunnels).
•Toll since 00:00: this is the collected toll amount since 00:00 of the current
day. The counter is reset every night at 00:00. Current day: midnight CET =
GMT +1
•Km since 00:00: this is the collected distance in km since 00:00 of the
current day. The counter is reset every night at 0:00.
•Licence plate number: the licence plate number of the vehicle to enable the
driver to check if he is using the correct OBU in the current vehicle.
