REVISION HISTORY

SAFETY INSTRUCTIONS

• Only skilled and instructed persons shall install and connect the device.
• Proper experience in working with mains voltage, electrical and electronic devices is required.
• Do not connect the devices directly to mains voltage, instead use the voltage given in the manual.
• Do not wire any connections while power is applied to the device.
• Ground the devices carefully to prevent electrical shock.
• All connectors are pin-coded and fit in only one position.
• Mount the devices carefully to prevent them from shifting or dropping.
• The sensor shall not be opened as this will void the warranty and cause incorrect calibration of the sensor.
• Ensure adequate ventilation during operation.
• Unused connections should be covered with a sealing cap.
• Use an enclosure for the sensor to protect against environmental conditions.
• Only use fully functional equipment (ladders, aerial work platform, …) when working above ground.
• The devices must be mounted to a stiff and solid support.
• Vibration, oscillation or any kind of movement will reduce the sensor performance.
• Make sure that your installation methods are in accordance with local safety policy and procedures and company practices. The protective conductor connection must not be used for other purposes. It must have a permanent electrical continuity and mechanical strength.

QUICK START

Install IMD

IMD-2002 TargetViewer

• The software package can be downloaded from our website at https://www.innosent.de/en/downloadportal/
• Execute the TargetViewer setup file and follow the instructions of the installation on your Windows PC.
• Note: Elevated administrator rights are required for the setup.

Mounting instruction

• Mount the IMD-2002 in a stationary position, e.g. on a tripod.
• Align the sensor in the desired direction and check the correct orientation and mounting angle for your required field of view.

Cable connection to sensor

To connect the sensor to your PC via USB-port, use the Beefy3 breakout board and the USB to Micro-USB cable. The connector of the sensor is compatible with the pinout of the Beefy3 board. The cable and the Beefy3 are included in the evaluation kit.

• The breakout board must be connected according to the picture below. You can find information about the sensor’s pinout in the data sheet.
• Configure cable latency in Windows device manager to 1ms (default 16ms).

Connect the TargetViewer to the sensor

• Click the ‘connect’ button in the top left corner.
• Choose the correct COM port and click OK.

Observe moving detections

Detections are output in a target list via UART.
Detailed information about a target is displayed in the target list in the lower area of the GUI.

• Red indicates targets moving toward the sensor (approaching).
• Green indicates targets moving away from the sensor (receding).

The environment is set up properly and ready for operation.

FEATURES

Blockage Detection / Anti-Masking

• Blockage Detection detects if the sensor is blocked or masked. You can find out with ‘Blockage Level’. This value is sent cyclic in the target list header, see [2].
• It provides a value in [%], which indicates an attenuation of the received signal.
• This value can be used to calibrate to an enclosure. This will then not cause any false alarm for blockage.
• Configure the parameters in [4.2] to find the sweet spot for your application.

Estimated Time of Arrival – ETA

The Estimated Time of Arrival [s] is calculated in the sensor and output in the target list. Each target has this value.
The ETA is calculated with the assumption, that the target is

• approaching towards the sensor and
• in boresight

Note: If the object moves in a different direction, then the ETA is not reliable, see figure below.

SENSOR CONFIGURATION

First, read settings from sensor:

Caution: If you send settings before reading from sensor, default values are applied and your customized settings are overwritten.

• Settings are set to sensor, after button ‚Send Configuration from System‘ has been pressed.

General Settings

• Press the button ‘Configuration’.

Note: The button is only active if the connection to the sensor is established properly. You can check that by reviewing the firmware field on the right side. If the version could be read, the connection was successful.

• In the configuration wizard you can set the desired configuration.

Note: These settings are set in the sensor and have direct impact on the signal processing chain.

• Frequency Channel: Choose a frequency channel. Prevent interference, if more than one sensor is operating nearby.
• False Alarm Suppression: Enable false alarm suppression to filter out spurious detections occurring randomly. Decrease false positives.

Note

• This setting causes an additional latency of 250 ms.

Sensor Configuration – Blockage Detection

Blockage Detection detects if the sensor is blocked or masked. You can find out with ‘Blockage Level’. This value is sent cyclic in the target list header, see [2]. Configure the following parameters to find the sweet spot for your application.

Example: If you place the sensor behind an enclosure, you set the Blockage Min Level to 0% and start evaluating a proper value for blockage detection.

• Blockage Min Level: Set this value to 0%, if the sensor is used in a housing or with a radom.
• Blockage Threshold: Set this threshold if the current blockage level exceeds this value, the blockage flag in the target list will be set.
• Set Default Blockage Parameter: Resets the blockage min level and the blockage threshold to default values: Blockage Min: 20% Blockage Threshold: 0%

Sensor Configuration – Filter Settings

• You have the possibility to set 2 filters to create different types of alarm zones. The setting options for Filter 1 and Filter 2 are the same.

Note: Each filter needs to be enabled specifically.
Caution: Filters have positive logic. This means, only targets which fit to filter settings, pass them.

• Enable Filter: If checkbox is set, this filter is enabled.
• Range Filter: With the range filter you can create “alarm zones” where the detection is active. Only targets in-between min and max range thresholds pass this filter.
• Velocity Filter: Targets in-between min and max velocity thresholds pass this filter. The velocity filter can be set to 0 up to 7,78 m/s.
• Direction: The direction selector lets you determine how the velocity filter should be applied:
  • v_pos: Positive values pass the filter (receding).
  • v_neg: Negative values pass the filter (approaching).
  • v_both (default): Negative and positive values pass.
• Example: If you set the velocity filter min to 2m/s and max to 5m/s. The negative (-2m/s to –5m/s) and positive (2m/s to 5m/s) values pass the filter.
• Signal Filter: Values in-between min and max signal strength pass the filter. Note: This filter depends on RCS of targets. Signal strength is not corrected by distance
• Angle Filter: Values in-between min and max angle pass the filter.

Sensor Configuration – Example for filter combination

Filter 1 and Filter 2 can be combined to two alarm zones.

No targets pass filter.

Velocity min/max [m/s]| 1/2| 4/7.8
Direction selection| v_neg (approaching)| v_pos (receding)
Signal min/max [dB]| 0/20| 20/80

Send configuration to the system

• After you have set the configuration, send the configuration to the sensor.
• If the configuration has been sent successfully to the sensor, the following message appears.

Note

• If an error message occurs, please check the cable connection to the sensor and reconnect.

Verify your configuration

• After setting the configuration, you can verify it by checking the plot.
• Only targets within the chosen limits of the filters will be processed and output by the sensor. The sensor outputs a maximum of 15 targets. Targets are displayed in the plot.
• Each target is displayed with an ID which represents its ID in the target list. This makes it easier to determine a target in your setup and accelerates the verification workflow.

Record data

• Choose a camera if you would like to record a video with the radar data.
• Press ‚start record‘ for recording the scene.
• Recordings can be viewed by pressing ‚playback‘.

FIRMWARE UPDATE

Update on PC via Target Viewer

• After you have successfully connected the sensor to your PC (chap. 2), you can perform a firmware update.
• Click on ‘Extras‘ and ‚Update Firmware‘.
• Connect update tool to the sensor.
• The latest firmware is always provided with the latest software package. Choose it and click ‚flash firmware‘.
• The update process is finished, when the following message appears.
