Together with a PTU01. a special application to be installed on a PC transmits, in real time, the lap time and numerous other information relating to the session to the driver display (position, number of laps, gap from the leader and gap from the person in front), emergency signals/flags and standard text messages. 

A radio transmitter to connect to the PC completes the system. The high range of the transmitter makes the system extremely functional and simple to instal.
