Firmware
The Firmware page provides a bulk firmware upgrade for all the types of connected devices to maintain them in the optimum condition. You can suspend bulk administration of the devices. Optionally, some devices can be excluded from bulk administration.
Tip
A new firmware version may be installed for one or more selected devices in the test mode and only then upgrade can be allowed for the other devices.
The current firmware version is available online via the 2N Update Server and, optionally, the upgrade file can be uploaded manually. The deployment of a new version is always subject to the administrator’s approval so that the whole upgrading process is under the administrator’s full control.
It may take a few minutes to get the firmware versions from the 2N update server.
The version displays a list of connected 2N intercom types, 2N answering units and 2N access units in bulk administration.
Note
The firmware version with electronic lock support is not included in the package on the update server. The firmware updates for IP devices managing electronic locks must be performed manually, independently of automatic system updates.
Make sure you have a 2N IP device with a special firmware version under management for a correct and full functioning of the electronic locks. Refer to https://www.2n.com/en-GB/2nos-elocks-fw for the firmware version that supports electronic locks.
Excluded Devices
To exclude a device from bulk firmware administration, add it to the list in .
Incompatible Firmware Versions
When added or upgraded, a device with incompatible firmware goes into the incompatible state. Incompatible state means that no new users are stored in the device. Events can still be downloaded from the device and its configuration or backup can still be used. A new record is created in the table and the administrator can enable the use of incompatible firmware.
Access Commander automatically excludes a device with firmware that is not supported by the latest firmware version. The card shows these unsupported firmware versions on the devices connected. See the list of supported firmware versions below.
Access Commander can control all the devices that use an unsupported firmware version when this version is approved. Approve the version in using the

Caution
The approval of an unsupported version may lead to such problems as data loss or some kind of malfunction.
