IDS NXT OS 4.0

You find the release notes for IDS NXT OS 4.0 under Release Notes for IDS NXT OS 4.0.0

IDS NXT cockpit 4.0

This version of the IDS NXT cockpit supports Windows 10 64-bit (version 22H2) and Windows 11 64-bit (version 22H2).

General improvements

Graphical revision of the GPIO setting for setting the logical value.
Adaptation of the dashboard in the "Trigger" display element to the trigger behavior of the IDS NXT malibu.

Bug fixes

An error could mean that the connection to the camera could not be automatically re-established after changing the IP address. This error has been fixed.
IDS NXT rio and IDS NXT rome: An error caused the IDS NXT cockpit to crash when the sensor ROI was set to minimum values. This bug has been fixed.

New and changed functions

The IDS NXT cockpit 4.0 supports IDS NXT malibu cameras.

You find the specific features of the IDS NXT malibu in the IDS NXT cockpit under Settings:

Camera: In the "Internal image processing" area, you define the image processing tasks that are performed directly on the camera, such as video noise filters or colour adjustments.
Streaming: Here, you configure the streams and enable RTSP streaming.
Interfaces: Here, you configure the GPIO interface of the camera.
Privacy (alpha): The privacy mode allows to blur people in the image and to blur static areas using ROIs. This feature is in the development phase and is offered for testing purposes.

Classifier 4.0.0

The vision app Classifier 4.0 only supports IDS NXT malibu cameras. For IDS NXT rio and IDS NXT rome, use the vision app Classifier 3.1.

Object Detector 4.0.0

The vision app Object Detector 4.0 only supports IDS NXT malibu cameras. For IDS NXT rio and IDS NXT rome, use the vision app Object Detector 3.1.

OPC UA Server

4.0.1

The UserIdentityTokens for authentication have been extended. This supports compatibility with other OPC UA clients, such as the OPC UA client from CODESYS.

4.0.0

The vision app only supports IDS NXT rio and IDS NXT rome cameras.
You can use a camera output to signal when the result nodes of a vision app are updated.

Known issues

IDS NXT OS / IDS NXT cockpit	Upload backups	The size of the maximum possible backup is limited to the free RAM space of the camera at the time of upload.
IDS NXT OS / IDS NXT cockpit	IDS NXT malibu	A bug may close the camera connection when the image is flipped and the camera is operated in "Hardware" trigger mode.
IDS NXT cockpit	IDS NXT malibu	If multiple IDS NXT cockpits are opened on a PC at the same time, the IDS NXT malibu is only displayed in the Finder of one IDS NXT cockpit.
IDS NXT cockpit	Vision app "Crawler" is no longer usable.	The separate vision app "Crawler" is no longer compatible with IDS NXT cockpit 2.3.0 or higher, as the Crawler application has been integrated into IDS NXT cockpit from version 2.3 on. If you are working with an IDS NXT cockpit version 2.3.0 or higher, uninstall the Vision App "Crawler" if it is still installed on the camera.
IDS NXT cockpit	Icon for Crawler is displayed 2x in IDS NXT cockpit.	If the vision app "Crawler" is still installed on the camera after an update to IDS NXT cockpit 2.3, the crawler icons are displayed 2x in the IDS NXT cockpit. Uninstall the previous vision app "Crawler" on the camera.
IDS NXT cockpit	Mixed operation of IDS NXT cockpit and IDS peak	In the case of mixed operation with IDS peak, uninstalling IDS peak or IDS NXT cockpit may lead to complications when updating the GUF files. After uninstalling, reinstall the remaining software to fix the problem.
IDS NXT cockpit	Vision apps and previous ROI feature (IDS NXT OS < 1.3.0)	If vision apps are still using the previous ROI feature, the ROI may show an incorrect position when switching binning.
IDS NXT cockpit	Multi camera viewer and vision app selection	If you have already selected a vision app for a camera in the multicamera viewer and you subsequently install a new vision app on this camera or delete a vision app, the vision app selection in the multicamera viewer is reset. Set up the vision apps on the camera. Configure the multi camera viewer. Select the vision app in the multi camera viewer.
IDS NXT cockpit	Maximum frame rate in freerun mode	To achieve the maximum frame rate in freerun mode, no images should be displayed with the IDS NXT cockpit due to performance reasons.
Vision apps	Vision app crashed	If a vision app has crashed, you have the following options to restart it: Open the IDS NXT cockpit and restart the vision app in the VApp Manager. When the camera is restarted, the vision app is automatically restarted. If the problem persists, contact the vision app developer.
Object Detector	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Nets with attention maps	It was noticed that in certain cases classification results differ significantly, which is likely due to the different net architectures. If you use nets with attention maps, you may get different results compared to nets without attention maps. These differences occur because different net architectures are used for training. For serial application, we recommend to use nets without attention maps.
OPC UA Server	New installation of a vision app	After reinstalling a vision app, it may be necessary to call the "PrepareRecipe" method twice to enable the corresponding recipe. Alternatively, after reinstalling a vision app, it is recommended to start it once initially.
IDS NXT Vision App Creator	Update of the IDS NXT Vision App Creator	After an update, the setting of the alternative "Source Folder" for projects must be reset.
IDS NXT Vision App Creator	Update the virtual machine	During the update, the virtual machine is deleted and replaced by a new one. Before updating, you must manually back up files that you have stored in the previous virtual machine and want to use further.
IDS NXT Vision App Creator	Uninstallation	The installation of the IDS NXT Vision App Creator does not require administrator privileges. If you installed the previous version as an administrator, the uninstall entry in the Control Panel may not be removed automatically. Go to "Control Panel" → "Programs and Features" and uninstall the previous version of IDS NXT Vision App Creator here.
