antenna pattern:
11º x 90º (+/-5,5º x +/-45º)
Mechanical Data:
size of the single Radar housings:
100 x 100 x 42
waterproofed and vibration proofed
Interface:
The interface of the Radar consists of 2 industriell M12 5 pole connectors; one is female, one is
male. The Radars can be connected from Radar to Radar in a chain. One end is connected to a
monitoring system which reads the informations of the Radar or the Radars on the CAN-bus. The
other end has to be connected to a 120 Ohm resistor. Normally the wires of these kind of connectors
have standarized colours. The user also can create his own cables with other colours. In the
following table the connetion of the Radar is descripted from the standarized colour point of view.

Two kinds of cable can/should be used: a 5-pole cable for connecting 2 Radars working in a pair
set; a 4 pole cable outside the pairs for connecting other Radars or also other pairs at the same
vehicle.

Cable Specification
The cable shall be shielded. The shield shall be connected to the metal housing of the connectors.
Functional Description
After switching on the power of the Radar a periodic readout will start every 71ms. But the Radar is
in an undefined status now. It has to be configured by CAN instructions. All settings are stored in
non-volatile memory. The following settings can be done: the ID of the Radar, the type (single, pair
master or pair slave,etc..), setting for the zones, the width of the truck and the sensitivity.

The CAN data rate is 250kBit. The CAN specification is 2.0A and 2.0B standard.
The CAN standard of 29 Bit indentifier is used where the last few bit can be variable due to the
message type and the ID of the Radar.
