Installation Notes 4.1 Equipment and wiring harness docking 4.1.1 Host front and back view 4.1.2 Host side view 11 RDT600 Installation Instruction Ver.1.1 4.1.3 System connection diagram 4.2 Equipment and wiring harness docking 12 RDT600 Installation Instruction Ver.1.1 4.2.1 Installation location requirements 1). The host is fixed near the rearview mirror of the front windshield (the top function line is hidden in the roof compartment), and it is as close as possible to the middle of the entire width of the windshield. 2). Before installing and fixing, ensure that the ADAS camera is horizontally illuminated on the road surface and does not deviate from the straight line of the road. It is required to check whether there is any potential risk of line damage or equipment failure on the vehicle at the selected location. 3). If there is a lens from another manufacturer occupying the position, use the "overlay method" to install and fix it, and try to ensure that the lens is centered. 4). After determining the installation location of the host, wipe the windshield of the installation area with cleaning paper to ensure that the relevant area is clean. 5). Take off the ADAS camera lens sticker, tear off the 3M adhesive sticker of the main unit and stick it well. 6). After pasting the main unit, press it hard to make the main unit firmly stick to the glass, so as to prevent the main unit from loosening or falling off. 4.2.2 Host wiring The wiring of the equipment should be as dark as possible . Ensure that the operating table is clean and beautiful ; The wiring harness exposed outside the cab ( if any) needs to be protected by corrugated tubes , And need to avoid frequently moving parts , Prevent damage to the wire harness due to vibration and pulling during use . First find the body's constant power line (Vin) , car ignition switch line (ACC) , ground line (GND) , left and right steering and brake signal lines . Usually available 13 Find the corresponding wiring position through the instructions of the body fuse box , As shown below :

RDT600 Installation Instruction Ver.1.1 If the description of the fuse box is vague and cannot be judged , The corresponding wiring harness can be found through the electric pen measurement method . The judgment method is as follows :

Normal power line (Vin ) : When the vehicle is turned off, use an electric pen to measure whether the line has electricity . If there is electricity, it can be judged that the line is a normal power line , and then measure the voltage , Make sure it is within the range of use of the device . Ignition signal wire (ACC ) : Through electric pen measurement , if the line voltage is 0V , the line is charged after the vehicle is ignited , then it can be judged that the line is the ignition signal line . Then make a voltage measurement , Make sure the voltage is working properly . Brake and left and right turn signal lines : Measured by electric pen , When the vehicle does not turn on the left and right turn signals, the line has no voltage , There is voltage on the line when the vehicle turns left and right . It means that the line is the left and right steering signal line ; The same goes for the brakes . If the signal line cannot be determined through the above methods , Please contact the team or other professional auto repair shop for assistance . According to different customer needs , other unused wiring harnesses such as 485 communication wires , etc. , can not be connected if there is no requirement , but must be wrapped with insulating tape to ensure that the exposed part of the wire does not contact any part of the vehicle body . 4.2.3 ADAS camera debugging Open and log in the mobile APP , preview the real-time video of the ADAS channel, adjust the camera angle so that the horizontal line of the cross star in the image is flush with the skyline of the road, and the vertical line is flush with the center of the lane. 14 RDT600 Installation Instruction Ver.1.1 4.3 DMS camera installation and debugging 4.3.1 Installation location requirements DMS The camera is installed in front of the driver , distance from driver's face 60cm~ 120cm range , The angle between the normal line of the face and the driver is required to be less than 30 when looking straight ahead ; the angle between the normal line of the face and the face in the vertical direction is less than 30 , as shown in the figure below . 4.3.2 Installation steps Step 1: According to the installation location requirements, find a suitable installation location on the 15 RDT600 Installation Instruction Ver.1.1 front windshield near the left A- pillar (you can power on the device first, and check the DMS video screen through the mobile APP real-time video to confirm whether the installation location is suitable) , and use a paper towel Or clean the installation position with a dry towel, tear off the 3M adhesive sticker on the base of the DMS camera , stick the base to the installation position on the windshield and use a little force to make it stick firmly . Step 2: When adjusting the angle, the installer needs to fasten the seat belt, open and log in the mobile APP, preview the real-time video of the DMS channel, and adjust the camera angle so that the driver's face is in the center of the screen as much as possible, as shown in the figure below (the position inside the red dotted line box in the figure ):

4.3.3 Routing and precautions Since the camera is installed in ensured that it will not block the driver's vision after installation . In the camera image, it should be ensured that the steering wheel does not block the driver's face. If there is a need for occlusion, the installation location needs to be changed . The wiring of the equipment should try to ensure that the dark line is used.Ensure that the operating table is clean and beautifulExposed wiring harnesses need to be protected by bellowsPrevent breakage during later use . front of the drive, it must be 4.4 GPS antenna installation The installation position of the GPS antenna is preferably on the roof, and the wiring can be drilled into the car through holes or along the door gap. If it cannot be installed on the roof, it is recommended to 16 install it on the console in front of the passenger seat, as close to the window as possible. The distance from the electronic equipment is more than 50cm, pay attention to the receiving side of the antenna facing up, and tear off the 3M adhesive protective film and stick it on the table to ensure that the antenna is stable during driving. It is strictly forbidden to stick the GPS antenna on the equipment. RDT600 Installation Instruction Ver.1.1 4.5 Storage media and IoT card installation ( picture) 5.
