UNIPRO – The original Laptimer
20
The Main Box
The main box is where most of the processing takes place. The Laptimer has a powerful 16-bit
processor and three different memories. The whole system is built with low energy components,
which gives you the benefit of a very long lifetime on the battery. The main box with all the cables
and connectors are placed behind the front cover and is only connected to the Display Unit with
one single cable. This way you will not be troubled by a lot of cables on your steering wheel.
Connectors
The Laptimer has 9 high quality connectors plus the cable going to the connector on the Display
Unit. This section will give a short overview over the different connectors and their purpose.
!
The names of the connectors are marked clearly on the Main Box. It is important that
you only use the connectors for the purpose they are mend for.

Please use the rubber protection caps on connectors that are not in use. This will protect the
connectors against water and dirt, and will ensure the correct operation of the Laptimer, even in
rainy weather.
