Here is a summary of the changes and new functionalities. For a detailed explanation of the communication protocol, features and message structure, please check the communication protocol document available in the documentation. ### Slots replacing tags Slots are the new way to keep track of the configurations applied to the NEON Vibration Sensor. Now, instead of using variable tags, the device has several slots available per configuration. If you save a configuration in slot 0, you can add a configuration to slot 1 or update the configuration in slot 0. Furthermore, the slot is now visible in the measurement messages, allowing users to tie a measurement to a specific configuration. ### Triaxial measurement A new type of measurement has been added to allow users and the device to send the 3 axes of a measurement in a single message. For example, having in a simple message the RMS velocity for the X, Y and Z axes. ### Envelope measurements The NEON Vibration Sensor using protocol v4.1 now supports envelope measurements (RMS envelope and peak envelope) ### Revised Statistics Users can now select in a single configuration all the desired statistics measurements instead of having to send a downlink per measurement. ### Sample Speed Divider calculated automatically The sample speed divider is now calculated based on the frequency range selected instead of having to define it as a parameter in the vibration settings. --- # Agent Instructions This documentation is published with GitBook.
