2025.02.25: Mobile and I/O POST/GET Service Removal with RutOS 7.14

With the release of RutOS version 7.14, support for the OTD140 POST/GET service will be discontinued to enhance security while maintaining device functionality through alternative methods.

PCN Number: PCN_RUTOS 7.14_POST_GET_Removal_OTD140_2025_02_25_EN

Change description
Change type	Firmware change
Detailed description	With the introduction of RutOS 7.14, the Mobile POST/GET and I/O POST/GET services will be removed from the firmware and will no longer be available in the package manager.

Change description
Change type	RutOS System Integrity Enhancement
Detailed description	With the release of RutOS version 7.14, the device’s critical system files will become read-only by default. This prevents unauthorized or accidental modifications that could damage the system’s integrity. Standard users operating within typical parameters should not be affected, while those who rely on direct file alterations will need to adjust their workflows. Custom firmware options are expected to allow reverting to a more flexible configuration if required.
Change reasons	To maintain system integrity, enhance reliability, and prevent unintended damage to core files.

OTD140	OTD140 ******	No changes
Upcoming change date	Q2 2025

Change impact
Risk assessment	Customers performing direct system-level modifications may need to adjust their procedures. Standard end-users, who do not rely on altering critical system files, are unlikely to be affected. Custom firmware solutions can restore file-level flexibility if required.
Suggested implementation plan	Information included in this PCN will help adapt to the upcoming changes. For more detailed information, please contact your sales representative. Review current workflows and identify any reliance on direct system file modifications. Consider using custom firmware builds if continued system-level customization is necessary.

2024.03.08: Reset button functionality change RutOS 7.07

With the release of RutOS version 7.07, OTD140 device will experience changes related to the security improvements of the device.

PCN Number: PCN_RUTOS_CHANGE_2024_03_08_EN

Change description
Change type	Firmware change
Detailed description	Previously, during device resets, logs, RMS connection state data, and SIM PIN settings remained unchanged. However, starting with RutOS firmware version 7.07, all devices will uniformly reset logs, RMS connection state data, and SIM PIN settings to factory defaults when using the reset button. Other reset methods, including WebUI, SMS, and others, will remain unimpacted by this change.
Change reasons	Increasing security

Affected products information
Model	Affected order codes	Order code changes
OTD140	OTD140 ******	No changes
Upcoming change date	2024 Q2, with the release of RutOS 7.07

Change impact
Risk assessment	The loss of device logs upon utilizing the reset button may disrupt operational records and slow down subsequent troubleshooting efforts. Failure to set up the SIM PIN post-reset via the reset button may result in SIM card lockout due to repeated incorrect PIN entries, causing service disruption and requiring either SIM replacement or PIN reset. The device is still visible in RMS post-reset but cannot be accessed. Therefore, re-adding the device to RMS is necessary for continued access.
Suggested implementation plan	Information included in this PCN will help adapt to the upcoming changes. For more detailed information, please contact your sales representative.
