Wiring diagram

Wiring connectlon

Note:1.If the trigger cable won't be used, please wrap thecable to avoid short circuit.2.The Trigger output is negative, the Max. input currentshould be no more than 500mA.

Sensor Installation

1. Installation height

2. Requirements for vertical installation angle

Installation height	Upward angle
0.6-0.75m	10°
0.75-1.3m	5°

3. Sensor fix
The radar is installed on the vehicle body with a bracket, and the vertical installation angle is adjusted through the mounting bracket.

Control boxinstallation
1. In order to connect the cables easier, the control box is suggested to lay in the cabin.

2. The control box should be sticked on the metal part of the vehicle. In order to fix thecontrol box firmly, before stick, please clean the surface.

Function descrlptlon

1.System self diagnosisAfter the system is powered on, it will start self diagnosis and show the self diagnosis result via display.

2. Reversing warning function 2.1. Start conditionsa.IGNONb. The gear is in reverse

2.2 Reversing alarm
a. The distance is showed according to the distance of the object, and the buzzer alarms according to this distance;

b.The default alarm area of the system is shown in the figure below:

c.The default alarm and distance segment of the system are shown in the following table:

d. When the display is providing warning, the trigger will drive external equipment.

3.Detection range setting function
The detection range of the radar is shown in the following figure. For different types of vehices and conditions,the radar can be used by PC-side configuration soffware, using CAN bus tools to configure the detection area.
L1: The distance from the mounting position of' the sensor to the rear end of the vehicle (set range 0-2m, accurate to 0.1m).Default value: Om;
L2: For the warning distance(set range from 1-30m, accurate to 0.1m),Default value:10.Om;
W1: The detection width on the left side of the sensor (set range from 1m to 5m, accurate to0.1m),Default value:1.3m;
W2: The detection width on the right side of the sensor (set range from 1m to 5m, accurate to0.1m),Default value:1.3m.

4.Learning function
When the Installatlon poslton of the radar Is not at the outermost slde of the vehice,the sensor Is easy to detect theaccessories of the vehicle or vehicle body, which will result in false alarm. Therefore, in order not to make false alarm,it isnecessary to enter the learning mode to make the sensor identily the detected target as the body accessories.Users need to follow the following steps to achieve the learing function:

4.1. Move the vehicle to an open area and confirm that there are no obstaces other than body accessorles within (a)m of the
radar;The setup range (a)m depends on the distance L1, a> 4*L1, so the Min. value of a is 3m.

4.2. Power on the system and wait for the completion of system self diagnosis;

4.3. Press and hold the setup button for 4.5s-6s, the system wl start learling and dlsplay will show the learnlng progress ondlsplay.
