3.1.2 Control unit
The Control Unit, or DAD, is the central part of the system because it communicates with
the antenna, the laptop and the encoder, making all the systems work together.
The DAD is lodged in the antenna box and has a power button on top of it to turn it on/off
(see Fig. 3.1).
The characteristics of the Control Unit are:
Voltage: 12 V +/- 10%
Environment feature: IP 65
Absorbed power: 8 W
Operating temperature: -10/+40 °C

3.1.3 Encoders
The Opera Duo employs two encoders for acquisition distance measuring, each one is
positioned inside one of the wheels.
This feature ensures that the distance is correctly registered even in rough terrain when, at
times, only one wheel is touching the ground.
