Figure 2.1: Block diagram of the Waveguide 5 Direction-Onboard 2. The three sensors A, B and C are connected
to the local network as well as the processing unit. This diagram assumes the processing unit and the radars to be
powered by a single power supply.
For the system to function, the three radars and the processing unit must be powered and
connected to a local network. The processing unit provides the option to export data over
Ethernet or two RS232 serial ports and allows the use of a USB drive for storing data.
Additionally each of the radars has an internal data storage.
Depending on the installation location a junction box with a network switch can be used
to reduce the length of required cable.
The following sections explain the detailed connection of the radars and the processing
unit.
