5.1 System Description
The Infrared Tyre Pressure & Temperature Monitoring System (IRTPTMS) monitors vehicle tyre pressures and
temperatures.
A typical system is comprised of the following components:
 1 Motorsport DigiTyre ECU (MDE)
 Up to 4 wheel electronics including mounting system
 Up to 4 digital antennas
 Up to 4 trigger transmitters
The wheel electronic mounted on the wheel rim measures tyre pressure ambient temperature and tyre carcass
temperature at regular intervals and transfers the values wirelessly to the reception antenna(s). The current pressure
and temperature values can be requested specifically via the LF trigger function. In the digital antenna, the radio data
telegram is decoded and transferred to the ECU unit as a digital signal. The ECU unit evaluates the received data and
forwards the information as required.
