Component Description
EVT-300 Components
The Eaton VORAD EVT-300 Collision Warning System is comprised of four
main components: the Antenna Assembly, Central Processing Unit, Driver
Display Unit, and the Interconnecting Harness. Two components, the Side
Sensor and Side Sensor Display, are optional. Each of the components are
shown in their approximate location on a vehicle (see Figure 1 below), and
their functions are described in the following paragraphs.
Antenna Assembly
The Antenna Assembly located on the front of the vehicle, transmits and
receives low power, high frequency radar signals. The transmitted radar sig-
nals are reflected off objects in front of the vehicle and are received back at the
Antenna Assembly. The Antenna Assembly compares the difference between
the transmitted and received signals, converts this information into a digital
format, and transmits it to the Central Processing Unit (see page 6) for addi-
tional processing. The Antenna Assembly is usually mounted in the center of
the bumper. This mounting location ensures that the radar beam is aimed
directly in front of the vehicle. The Antenna Assembly will simultaneously
monitor up to 20 objects within a 350 feet (106 m) range, whether moving or
stationary.
