Sensor Interfaces and Configuration
CAN-Bus Communication
The PreView
®
Side Defender
™
radar has one CAN interface as specified 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
