10.1 Updating the firmware of ABAX 2 wireless devices
During the controller firmware update, programs enabling the update of the firmware of
ABAX 2 system devices are also saved to the controller memory. If devices with outdated
versions of firmware are registered in the controller, their firmware is updated by the
controller automatically. The process of verification of the firmware of registered devices is
run after each controller firmware update, as well as after adding new devices.
If attempts to automatically update the firmware of devices fail (e.g. as a result of radio signal
interference or device power trouble), the icon will be displayed in the ABAX 2 Soft
program at the device firmware version. You can then click the button (see “Devices
status” p. 21 and “Keyfob state” p. 24) to restart the update process.
At the final phase of the firmware update, the device does not perform its normal
functions for a few seconds.
If you do not want the controller to automatically update the firmware of the devices
registered in it, enable the “No automatic update of wireless devices firmware” option
in the controller.
