1. ASR100 Side Radar Introduction
ASR100 is a millimeter-wave radar based on the 77 GHz frequency band, with an ultrawide field of view. The millimeter-wave radar can accurately measure the target
distance, speed, angle, and other information through the difference in echoes between
the transmitting and receiving electromagnetic waves. It is an all-weather and all-day
operational radar system. The millimeter-wave radar warns the driver of any dangerous
target in the blind spot and reminds the driver to make timely adjustments to the driving
trajectory to avoid accidents.
The ASR100 millimeter-wave radar has 180°target detection coverage, with a large
detection range of up to 80m. It comes with collision pre-determination and gradedalarm function, can integrate with external CAN (Controller Area Network) and CAN
FD (Flexible Data) interfaces, and supports 12V or 24V supply voltage. The radarfeatures a compact structure and superior performance, is highly cost effective and easy
to install, and can meet forward, side, and reverse obstruction warning requirements forpassenger and commercial vehicles.

Note: The default cable included is 8 m in length.

2. Precautions for Product Use
Please read the precautions carefully before use, to avoid any problems with the productor its usage.
(1) While installing, ensure the device is not powered on.
(2) Please follow the installation instructions for the radar sensor to avoid theinstallation error exceeding the error limit.
(3) ASR100 millimeter-wave radar performs automatic fault detection afterpower-on. If there is a fault, please do not use it.
(4) Be sure to conduct the test in an outdoor open field and pay attention to thesafety of vehicles and personnel.
If you encounter problems that cannot be resolved, please contact Autel’s customer
service staff. We will diligently help you resolve the problem at the earliest!

3. Packing List
The packing list includes: millimeter-wave radar sensor (as shown in Figure 3), 1
connecting cable (as shown in Figure 4), a spirit level (as shown in Figure 5), and2

several fixing screws. The mounting bracket can be purchased separately according tocustomer needs. The mounting bracket is not supplied with the radar by default.
Note: The radar and the bracket can be fixed with 4 M2.5 screws.

When the ASR100 millimeter-wave radar is used, the radar module is normallypowered by the vehicle power supply, the main communication interface of the radaris the CAN interface connection. The radar outputs detection and warning information
to the client.

4.3 ASR100 side radar installation and calibration
Radar Installation
Installation position: The radar should be installed on the right side of the truck. For
right rudder country please install on the left side of the truck. We recommend you
install it on the side guard plate, side guard rail of the truck.

Installation height: We recommend you install the radar at a height of 30-120 cm
above ground.
Installation deviations: To ensure detection accuracy, the radar installation horizontal
angle error should be within ±1°. Installation vertical angle error should be within 2°.

Installation Vertical Angle
30-120cm

Example of InstallationIn order to control installation deviations, an optional auxiliary mounting bracket can5

be used to adjust the direction and angle during installation.
1. With the front of the radar (the side with the plastic casing) facing the detection area,
fix the radar to the mounting bracket using the screws.
2. Place the spirit level in the middle of the upper plane of the radar and adjust themounting position adjustment screw until the bubble overlaps the ring in the middle.
3. Secure the mounting position adjustment screw, and then connect the cable.

Radar Wiring
After the radar cable is connected to the radar, it should be routed into the cab
together with the chassis cable, as shown in the image below.

The entry for the chassis cable into the cab is at the bottom of the cab. Therefore, youneed to lift the cab during wiring, as shown in the image below.

6In front of the front passenger seat (where the main fuse and the main ECU are located),connect the power supply, the display screen and the other parts of this product, asshown in the image below.

Input Signal Access
The Autel ASR100 requires the 5 interior signals below for its normal operation. The
radar automatically reads these CAN J1939 signals by default:
1. Vehicle speed
2. Steering wheel angle
3. Yaw rate
4. Longitudinal acceleration
5. Lateral acceleration

5.1 Installation precautions
1. When the radar sensor is installed, the triangular surface (plastic casing surface)should face the detection area, and the left and right sides and the front should not be
blocked by any metal objects.
2. It is not recommended to install the radar on the vehicle’s protective cover.
3. The radar should be installed at a position far from where other equipment arefrequently operated
4. The radar should be installed away from high heat sources such as motor
actuators and drivers.

5.2 Notes on usage risks
1. When there are foreign objects such as mist, ice particles, snow or cement on
the surface of the radome, please clean it before use.
2. The radome should only be wiped with a damp, lint-free cotton cloth; do notscratch or damage the surface of the radome.
3. Welding should not be conducted near the sensor location.
