1.3.1 FIRMWARE UPDATES
Z41 Pro incorporates two separate microcontrollers. One of them is focused on
interfacing with the KNX bus and on running the application program itself, while the
second one is dedicated to running the firmware that implements the operating system
and the management of the peripherals.
Therefore, an occasional update of Z41 Pro may consist in two phases:
Downloading the new application program (from ETS),
Downloading the new firmware.
Two alternative methods are provided for the latter: the connection of a flash memory
drive to the USB slot (see 9 in Figure 1) through the proper adapter, or the connection
of an Ethernet network cable (see 7 in Figure 1).
For further details on the update process, please refer to the specific document “Z41 –
Firmware update”, available at www.zennio.com.
Note: firmware updates do not re-set the consumption, alarm, error and other logs.
