OVERVIEW
This document describes the PreView® Side Defender™ radar system
manufactured by PRECO® Electronics, located in Boise, Idaho, USA. There are
two different systems described in this manual, the right (passenger) side system,
model SDR8503 and the left side system, model SDL8503. This document covers
the components that comprise the Side Defender™ radar systems – the Side
Defender™ radar sensor, the PreView® in-cab display and the sensor/display
interconnect cable. This document may be amended, corrected, and enhanced
in keeping with the sensor development progress.
Product Description
The PreView® Side Defender™ radar is a small, rugged radar sensor designed
by Preco® Electronics for side blind zone object detection in heavy duty over-
the-road applications. When combined with an in-cab display, it alerts drivers
to objects in the side blind zones of heavy trucks, busses, waste trucks, utility
trucks, re/ambulance and other heavy and medium-duty on-road vehicles. If
provided vehicle speed over a J1939 CAN-bus interface, the Side Defender™
has intelligent modes of operation that help minimize false alerts due to xed
objects such as guardrails, while still providing reliable side object detection.

The sensor frequency band is legal throughout most of the world, but check
with PRECO® Electronics or your country’s regulations before purchasing.
The Side Defender™ radar works in adverse weather conditions, has a wide
operating temperature range, is sealed to meet IP69K, withstands high vibration
and shock levels, and is maintenance free. Side Defender™ radar sensors
include an 8-pin Deutsch connector pigtail as shown in Figure 1.
Using a frequency modulated transmit waveform (FMCW), the Side Defender™
radar measures radial range, speed and angle, reectivity, and other parameters
of multiple stationary and moving targets simultaneously. This radar sensor has
a wide horizontal eld of view up to +/-75°, optimized for side object detection in
large trucks and busses. The horizontal eld-of-view is approximately 40 feet
along the sides and 10 feet wide as shown in Figure 2. This is designed to cover
one trafc lane adjacent the truck, while looking forward and aft approximately 20
feet (6m).
PreView® Side Defender™ radar can detect people, bicycles and other cars/
trucks within the detection zone, providing a visual alert on the in-cab LED display,
as well as an audible alert if the turn signal is deployed. Figure 3 shows the in-
cab LED display.

The Side Defender™ radar sensor performance is not affected by other PreView®
Side Defender™ radar or similar sensors operating in close proximity with each
other.
Other Sensor Features
The Side Defender™ radar has a continuous Built-In-Self-Test (BIST) that noties
the operator display of sensor failure within a fraction of a second. This test
functions by monitoring the transmit and receive performance as well as other
internal operations.
The Side Defender™ radar can also determine if the face of the sensor is blocked
with excessive ice, mud, or snow that is impeding proper operation. This blockage
is then reported to the operator display.
Both the self-test and blockage detection features are important to fail-safe
operation.
In-cab LED Display
Description
The in-cab display provides the vehicle operator with a visual indication of a
detected object anytime the vehicle is operating. The display unit also contains
a buzzer that provides an audible alert that only activates when the turn signal
is energized, providing the operator with another cue that an object is being
detected. The audible alert will only sound upon the rst detection of an object
while the turn signal is energized. The audible alert will not sound again until the
turn signal is cycled.

Sensor Interfaces and Conguration
CAN-Bus Communication
The PreView® Side Defender™ radar has one CAN interface as specied in ISO
11898-2 (SAE J1939) with a transmission rate of 250 KBits/second. The sensor
communicates with the PreView® In-cab LED display using this interface.
CAN-Bus Inputs
If the truck/bus speed is available via CAN-bus message, the Side Defender™
Radar can support certain J1939 vehicle speed messages (contact PRECO®
Electronics for more information).
CAN-Bus Outputs
The Side Defender™ can provide object detection information and alerts as CAN-
bus messages. This information can include distance, angle, velocity and signal
strength of detected objects. Telematics or data logging of detection events can
be supported via these CAN-bus outputs.
Turn Signal Input
The Side Defender™ radar requires a turn signal input for proper in-cab display
operation. When the turn signal is active, the display audible alert will sound
once when an object is detected. Refer to the system wiring diagram (Figure 4)
for connection information.
Alert Output
The Side Defender™ radar supports an alarm output signal that can be used to
provide additional operator alerts.

This output is an Active Low (switch to ground). One example use of this output is
to drive an LED indicator in a side mirror when there is an object in the side blind
zone. Contact PRECO® Electronics support for more information.
System Connections
Locate the vehicle’s ignition power wire and connect to the red wire on the sensor
harness. If it is necessary to extend the power wire on the supplied harness,
use 20AWG wire as a minimum. Locate the vehicle’s turn signal wire that is
associated with the turn signal on the side on which the sensor is being installed,
and connect to the blue wire. (Be sure that the turn signal wire selected activates
ONLY when the turn signal is active. On some trucks the daytime running lights
and/or air brakes will activate the wires connected to the turn signal lamp).
Connect the black wire of the sensor harness to vehicle ground.
System Operation
The Side Defender™ radar system has two different modes of operation
depending on if vehicle speed information is supplied to the system over the
J1939 CAN bus.
No Vehicle Speed Available
If vehicle speed is NOT available to the system, the Side Defender™ system will
detect and report all objects in the sensor eld of view.
Vehicle Speed is Available
If vehicle speed is available to the system, the sensor is capable of ltering out
stationary objects such as guardrails or concrete barriers, while still detecting
moving objects in the blind zone based on the speed. This feature minimizes
‘nuisance alerts’ due to stationary objects in the detection zone, e.g. guardrails,
signs, etc. This mode is optimized for on-highway blind zone collision mitigation
due to lane change or merging.

Installation
Sensor Mounting
The Side Defender™ radar mounting location is important for proper system
operation. Ideally the sensor should be mounted on the side of the vehicle
between 18” (45cm) and 24” (61cm) above the ground, as measured from level
ground to the bottom of the sensor. The sensor face should be perpendicular
to the ground with Side Defender™ text up and V logo pointing down. Select a
location that will provide some protection from impact and debris while allowing an
unobstructed view of the target hazard area. Refer to the Keep Out/Interference
Zones listed below.
Mounting Tolerances
For optimal performance, the vertical angle (up/down) tolerances are +5 degrees
(up) and -2 degrees (down), and the horizontal angle (side/side) tolerance is +/- 5
degrees.

The performance of the sensor can be negatively impacted if the sensor is
angled down, causing false detection from the ground. Any time the sensor is not
perpendicular to the ground, the performance should be tested.
Keep Out/Interference Zones
Metallic and any other strong radar reecting objects must remain outside of the
keep out zones dened in Figure 1. If radar reecting objects reside within the
keep out zones, testing must be performed to determine their inuence on the
sensor’s performance.

The sensor’s horizontal eld of view is +/- 75 degrees and the vertical eld
of view is +/- 10 degrees. For optimal performance, the sensor should
protrude beyond any other portion of the vehicle.
Important!
Before permanently installing the PreView® Side Defender™ Radar on the
vehicle, verify that the selected sensor mounting location provides a clear
detection zone. Take the vehicle to a clear area, temporarily attach the sensor
in the proposed mounting location, apply power to the system, and verify that
nothing is being detected.
Sensor Mounting Procedure
PRECO® Electronics supplies a 90 degree mounting bracket for the Side
Defender™ radar. If the provided 90°bracket is not appropriate, please contact
PRECO® Electronics
If mounting directly to the vehicle, follow the procedure outlined below.
1. Select the appropriate sensor mounting location in Figure 8.
2. The standard mounting conguration is with ‘Side Defender™’ text, as
shown in Figure 1.
3. Using the bracket as a drill template, scribe position marks through the
holes. Drill 1/4” (6mm) holes centered at the marks.
4. A 1.5” (40mm) diameter clearance hole may be required for the sensor
connector and mating cable connector.
5. Secure the sensor to the vehicle with the four supplied #10-24 UNC
button head screws, washers, and locking nuts or equivalent. Apply a maximum
torque of 22 lb-inch (25 kg-cm) when securing the sensor.

Initial System Power Up and Test
Once the sensor and display are installed, wired, and connected, power should be
applied to test correct system operation. When the system is operating correctly
in an open eld with no obstructions, the status LED indicating green will be the
only light illuminated. If the detection LED (yellow) is lit, check for any vehicle
obstruction which may be detected by the sensor. If possible, move the sensor so
it is not detecting the object(s). If it is not possible to relocate the sensor, consult
PRECO® Electronics.
If for some reason the system is malfunctioning, the status LED and detection
LED will ash in unison and the buzzer will emit a short stuttering sound. Refer to
the Troubleshooting section to determine the error and potential causes.
Once the system has been installed, the detection zone should be tested. This
test should be performed with two people, one who remains in the cab (the
operator), and one who walks through the sensor eld to the side of the vehicle
(the assistant). The operator engages the parking brake, depresses the vehicle
brake, and turns on the ignition. The assistant then walks through the detection
zone while the operator notes where the detection LED illuminates. Moving about
the side of the vehicle and noting when the detection LED illuminates is the way
to map an accurate detection zone.
Once the detection zone is determined, test the display buzzer operation. With
nothing in the sensor detection area (green LED on), activate the appropriate turn
signal. Have the assistant walk into the detection zone and verify that the display
detection LED illuminates and the display buzzer emits a short tone. With the
turn signal still activated, have the assistant walk out of the detection zone. Once
the detection LED turns off, have the assistant walk back into the zone again. At
this point, only the detection LED will illuminate. The display buzzer should not
sound.

Troubleshooting
Display Status LED is not illuminated:
• Verify that DC power (9-33V) is applied to the sensor.
• Verify that the cable between the sensor and display is connected.
Display Status LED and Detection LED are ashing:
• The display is not communicating with the sensor. Check connection
between display and sensor.
Detection LED is always illuminated when sensor is mounted:
• Verify the sensor is pointing outward from the vehicle in an open area
with no obstructions. This may require removing the mounting screws and lifting
the sensor out away from the side of the vehicle. If the detection LED is not
active when moved away from the vehicle, but is active when mounted, then the
sensors’ mounting position will have to be moved.
Detection LED is on frequently when driving around and there is
nothing in the detection zone:
• The sensor may be detecting a curb. Aim the sensor up about 2
degrees and check again. Do not aim the sensor up more than 5 degrees from
perpendicular to ground.
Detection buzzer sounds when turn signal is not active:
• The harness turn signal wire is being set by other electronics, i.e., daytime
running lights, air brakes, etc. Check turn signal wire connection.
The system is detecting stationary objects above 10mph (16kph):
• The sensor is not receiving speed messages over the CAN bus.

Object Detection Capability
The PreView® Side Defender™ radar system is a blind spot collision warning
system designed to supplement other safety practices and/or devices. The
machine operator is always the rst line of defense when safely operating
a vehicle. The person or owner responsible for the equipment must ensure
that all operators understand the installation, operation, limitations and
safe use of the system.
The Side Defender™ radar sensor can detect most objects within the detection
zone. However, there are some instances where objects can go undetected.
Obstacle size, shape, relative location, and composition are all factors determining
if, when, and where an object is detected. The Side Defender™ Radar sensor
operates by transmitting low power electromagnetic energy. Any energy that
strikes an object reects a certain amount of this energy back to the radar sensor
of the Side Defender™ Radar. If the returned energy is of sufcient magnitude, it
is used to indicate the presence of an object and determine the object’s distance.
While the radar sensor of the Side Defender™ Radar can resolve multiple objects,
only the object closest to the vehicle is reported to the operator display since it
represents the most signicant collision threat.
The amount of energy returned is based on a few factors:
Size – a larger object usually reects more energy than a smaller object.
Composition – a metal object typically reects more energy than a non-
metallic object. A metallic object at the edge of the maximum detection zone
might be detected, whereas a wood object may not.
Scattering – a solid object reects more energy than a non-solid object such
as tree branches, gravel, bushes, etc.
Shape – complex shapes cause energy to be returned in a very non-uniform
way. Very small variations or movement can change detection status.
Angle – an object that that is at-side perpendicular to the sensor will reect
more energy than an object at an angle. See below for an example of how
angle can affect returned energy.
