🧰 Prerequisites

📷Supported Hardware

This release only supports Visionary-T Mini CX devices: V3S105-1x

⚙️ Software and system requirements for firmware installation

We recommend using the latest version of the SOPAS Engineering Tool. You can find the latest version here.
For adequate SOPAS ET performance, use a PC with
- Operating systems:
  - Windows 10 (64 bit)
  - Windows 11
- X86 or x64-compatible processor, minimum: Intel Gen6 or equivalent
- Graphics processor supports OpenGL 4.3
- Screen resolution 1,024 x 768 or higher, at least 256 colors (65,536 colors recommended)
- Min. 450 MB disk space
- RAM: 1 GB RAM
- Ethernet: 1 Gbit/s or faster is recommended for best performance during configuration of the device via SOPAS ET and for streaming

🛠️ Installation

Please follow the instructions below and carefully read the release notes before starting the installation of the Visionary-T Mini CX firmware.

🔧 Preparation: Configuration backups

Before updating the firmware, ensure your device is powered and connected to your PC via Ethernet. To ensure your device configuration is preserved, please complete the step below before proceeding.

Save the Configuration
- Permanently save the current configuration on the device using either SOPAS ET or the respective API command.

💡 Recommended Best Practice: Write the configuration via the API as part of your application software. This allows for consistent parameterization across devices and automatic setup when integrating new cameras.

⚠️ Important Note on SOPAS ET Backups: Configuration files exported via SOPAS ET (*.sopas) are version-specific and cannot be restored on devices running different firmware versions. These backups are not backward or forward compatible, but they can still be useful for manual configuration of devices with the same firmware or as a reference.

🔄 Updating Firmware via SOPAS ET

To update the firmware of your device using SOPAS ET, follow these steps:

Launch SOPAS ET and ensure your device is connected.
In the right pane, click Search devices.
Double-click the listed Visionary-T Mini CX device you want to update.
💡 We recommend using port 2122 for the connection.
The device will now appear in the left pane.
In the device menu, click Download firmware and follow the on-screen instructions.

When prompted for credentials, log in using the Service user level.
User: Service
Password: [your custom password]
💡 If the password has not been changed, the default is: CUST_SERV
After the firmware update completes, install the device driver by selecting Device upload from within SOPAS ET.
⚠️ The option "Sick.com or a disk" is currently not supported.

Release version 4.0.0

New Features

Functionality	Description
PTP Status as a CoLa variable	Added variable (ptpState) to monitor PTP synchronisation status
LocationName variable	Changing the variable LocationName is now only possible while logged in. The default value of the variable has been updated to "SN <Serial number>".
New Web UI	Introduced a new web‑based user interface that is reachable in the browser via the IP adress. It provides toolles access to functions such as downloading the diagnostic file, retrieving the device status, and getting device details.

Bug Fixes

Bug fix	Description
Incorrect framerate after unexpected reset	Fixed issue where the frame rate was incorrectly set to 30 fps after an unexpected reset, even when the application was configured to use a different frame rate.
PTP synchronisation	Fixed issue where "PTP master mode" was not working. PTP synchronization is now fully functional in software timestamping mode.
IOValue variable documentation updatet	The documentation (telegram listing) for the variable IOValue has been updated to clarify that a value of 0 indicates "inactive" and a value of 1 indicates "active".
Save permanently	Fixed issue where permanently saved settings were lost after a power cycle in rare cases.
Behaviour of DeviceTime variable	Fixed issue where the DeviceTime variable was not being synchronized at the correct moment and was sometimes updated with delays. The DeviceTime is now synchronized exactly when the variable is read.
Cyber security fix	Fixed vulnerability.

Known limitations and issues

Limitation/Issue	Description:
Limited firmware downgrade	No firmware downgrade below version 3.0.0 possible after update
I/O logic configuration and effectiveness	No GUI to configure I/O logic, only via API variable INOUTx_active Logic changes get only active after either a physical change of the signal (input) or a logical change of the signal (output)
Incorrect documentation	Variable doutPinError erroneously lists eight IOs (instead of only six)
Increased switch-on delay	At (internal) temperatures below 0°C, the device needs a warm-up phase in order to turn on. Hence, the switch-on delay is increased compared to the ~20 seconds specified for temperatures >0°C.
CPU temperature availability	The CPU temperature is not available while being below 10°C.
Alleged change of device name	SOPAS ET suggests that the device name can be changed even without the required user level (unexpected). The changes are however not saved on the device (as expected).
Color map not saved	SOPAS ET does not save the colormap when exporting the visualisation settings.
Effectiveness of change of IP address	Importing a *.sopas file which changes the IP address requires to 1) save the paramerters permamently after the import and 2) to reboot the camera to complete the procedure
Inconsistent visualization	Deactivating distance-based filtering leads to a different visualization of the formerly filtered pixels in the point cloud in SOPAS ET. Their color can be less vibrant compared to the other points.

Release notes firmware version 2.0.0 [Click to expand]

New features

Functionality	Description
Time Synchronization	The clocks of an arbitrary number of cameras can now be synchronized via PTP or NTP. This allows for precise timing and offsets between the image acqusition of the individual cameras.
CPU temperature	The CPU temperature ia now accessible via API/Cola command alongside other temperature values.
Logs via webserver	Camera logs can now be viewed via webserver. Debugging logs can be exported and saved via webserver.
Cold start switch-on delay	The switch-on delay for cold starts in ambient temperatures between -10°C and 0°C has been reduced.
Improved Documentation	Missing information was added to the API documentation (CID description). Internal and irrelevant information was removed. The data structure is now also included in the documentation.
"Reached maximum client connections": TCP socket timeout	The default idle time required to automatically close unused sockets was decreased from 2 hours to 3 minutes. Hence, the likelyhood of reaching the maximum number of five client connections (and not being able to open new connections) due to e.g. lost/bad ethernet connection or crashing host applications, has been drastically reduced.

Bug fixes

Bug fix	Description
API variable "DeviceTime"	A bug was fixed which caused the variable DeviceTime to return "zero". The device time now returns the time/clock that is used for the timestamp of the frames such that they are directly comparable.
Data stream at ~0°C	A bug leading causing the data stream to fail at temperatures when starting the device around 0°C was fixed.

Release notes firmware version 1.6.0 [Click to expand]

New features

Feature	Description
State map	The device now streams a depth and intensity map as well as a state map. The state map helps to understand whether the data is missing due to a configured filter or due to other circumstances e.g. saturation effects.
Edge correction	Helps to eliminate errors which typically occurs at the edges of objects and corrects them to a sharper contour within the depth data.
Isolated pixel filter	Identifies isolated distance pixels within the scene and corrects their distance values compared to its neighbors.
Ambiguity based filter	Identifies and removes ambiguitities which can be caused for example by objects outside the unambiguity range and multipath reflections.
Remission based filter	Sets the distance values for all pixels outside the given object remission range to zero.
Digital IO	Digital IOs are available for in- and outputs. For example, trigger of single frames, power save mode or device warning.
Python 3	We have updated our Python 2.7 samples to Python 3 and provide them within our supporting material.
C++ programming samples update	The C++ programming samples have been updated in order to support the newly introduced state map.
ROS driver update	The ROS driver have been updated in order to support the newly introduced state map.
Update of customer documentation	We have updated for you the customer presentation and the device configuration guide within our documentation.
