1. ASR100 Side Radar Introduction
ASR100 is a millimeter-wave radar based on the 77 GHz frequency band, with an ultra-
wide 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 80 x 4.5 m. It comes with collision pre-determination and
graded alarm function, can integrate with external CAN (Controller Area Network) and
CAN FD (Flexible Data) interfaces, and supports 12V or 24V supplyvoltage. The radar
features a compact structure and superior performance, is highly cost effective and easy
to install, and can meet forward, side, and reverse obstruction warning requirements for
passenger and commercial vehicles.

2. Precautions for Product Use
Please read the precautions carefully before use, to avoid any problems with the product
or its usage.
(1) While installing, ensure the device is not powered on.
(2) Match the mounting bracket based on the product model. If the mounting
bracket does not match the product model after purchase, please promptly contact our
customer service for replacement.
(3) Please follow the installation instructions for the radar sensor to avoid the
installation error exceeding the error limit.
(4) ASR100 millimeter-wave radar performs automatic fault detection after
power-on. If there is a fault, please do not use it.

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!
Notice:
In order to protect human health, this device meets the thresholds for exposure of the
general public to electromagnetic fields according to Council Recommendation
1999/519/EC. This device should be installed and operated with at least 20 cm between
the radiator and your body.
The output power of the radio technology used in the Device is below the radio
frequency exposure limits set by the FCC. This device should be installed and operated
with a minimum distance of 20cm between the radiator and your body.
Important: Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
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), and
several fixing screws. The mounting bracket can be purchased separately according to
customer 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.

The ASR100 millimeter-wave radar connecting cable is illustrated schematically in
Figure 6 below:
Figure 6 Schematic illustration of the millimeter-wave radar connecting cable
In Figure 6, the Terminal A connector is connected to the radar, it has 8 pins, the pin
number in the figure corresponds to the pin definition in Table 1. The Terminal B is
connected to the vehicle and host computer. The color of each wire corresponds to
terminal A. Please check carefully when installing, and do not power on using an
incorrect connection.
4.2 ASR100 side radar connection relationship
When the ASR100 millimeter-wave radar is used, the radar module is powered by the
vehicle power supply, and the vehicle and the radar communicate through the CAN
interface connection. The radar outputs detection and warning information to the host
computer software through the CAN_FD interface. When the radar needs to be

upgraded or debugged, the radar and the host computer are connected through the
CAN_FD interface. The connection relationship is shown in Figure 7.

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 or side fuel tank of the truck.
Note: If you choose to install the radar on the fuel tank on the right side of the truck,
you need to purchase the professional mounting bracket.
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°.

Example of Installation
In order to control installation deviations, an optional auxiliary mounting bracket can
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 the
mounting position adjustment screw until the bubble overlaps the ring in the middle.
3. Secure the mounting position adjustment screw, and then connect the cable.

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, you
need to lift the cab during wiring, as shown in the image below.
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, as
shown in the image below.
Input Signal Access
The Autel ATS100 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
Power Access
The radar has to be powered via KL15 or Clamp 15 (24V). We recommend you find

8
KL15 on the main fuse board and connect the radar to it. On a Mercedes-Benz Actros,
for instance, KL15 (+) is located on the left side of main fuse board in front of the front
passenger seat, and KL31 (−) on the right side, as shown in the image below.
Installation and Risk Notes
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 are
frequently 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 not
scratch or damage the surface of the radome.
3. Welding should not be conducted near the sensor location.
4. Inspect the device daily before use.
