Easy device configuration for R1D2 radar ground speed sensor

The R1D radar ground speed sensor measures distance, velocity, and spatial position. To realize the maximum flexibility of the sensor, ifm's free software known as "Vision Assistant" is required for configuration. Download for free.

The following guides you through the setup process and explains the visualization of the Vision Assistant. Visit our FAQ section for more information.

Wiring devices
	Description
EC2112	CANfox for the connection of CAN devices to the USB interface of a PC
EC2113	Wired adapter cable for CAN or RS232 interface
EC2114	Wired programming cable for controllers and displays. With ntegrated CAN bus terminating resistor in connector housing. Voltage supply via individual wires with end ferrules.

Initial connection steps

Connect the sensor to your laptop via the CANfox and programming cable set shown above.

Open the software and click on "Find sensor".

In the "Found devices" popup window, click on the arrow next to the R1D sensor to connect.

If the sensor is not found automatically, click on "Manual connection". Then select "R1DXX1/R2DXX1 (CAN)" from the drop-down list and click on "Connect".

Upon initialization, the inclination instruction window will pop up.

The current inclination information for your sensor's installation is displayed.
If this installation is final, click on the box to set. Otherwise, close window for now.

Process values
• By default, process values are from the object closest to the sensor, i.e., "Shortest distance".
• Other objects, such as "Strongest power", "Strongest RCS", etc., can be selected depending on the application.
Range filters
• Filters for distance and power help fine tune the application solution
• In the image below, if object 2 is the target, the power filter can be reduced so that object 1 is ignored.
ROIs
• Up to 8 ROIs are freely configurable.
• The setting options are identical for each ROI
Advanced parameters
Three operating modes are available that impact maximum distance, distance resolution, and maximum velocity.
• See table below for details.
Distance smoothing
• Process values can jump when multiple objects are detected or uneven surfaces reflect multiple signals.
• "Distance smoothing" applies an exponential filter to provide a weighted average value.

CAN messaging

CAN messaging is ideal for applications requiring robust and efficient communication between multiple devices. It offers:

Differential signalling, making it resistant to electrical noise and ensuring reliable data transmission.
Priority arbitration, alling high-priority messages to be sent without delay.
Error handling, enhancing data integrity by detecting and correcting errors.
Decentralized communication, making it flexible and scalable by not requiring a central controller.
