INTRODUCTION
Products
Z41
,
Z41 Pro
and
Z41 Lite
incorporate
two separate
microcontrollers
, one
of which focuses 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, updating Z41, Z41 Lite and 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:
Downloading the firmware to Z41, Z41 Lite or Z41 Pro through a flash
memory drive connected to its
mini-USB
port
by means of a male mini-USB
to female USB adapter (ref. ZN1AC-UPUSB).
Downloading the firmware to Z41 or Z41 Pro through the local network from a
PC running the Windows operating system, by means of the
Ethernet
adapter (see the Z41 user manual) bundled with the original packaging of the
device.
This option is only available for Z41 and
Z41 Pro
, since product
Z41 Lite does not incorporate an Ethernet interface.
The next sections explain how to perform the firmware update for each of the two
alternate procedures, including the possible events that may take place during the
process, together with the suggested solutions.
Important
:
if successive restarts take place within the first two minutes of operation
after a firmware update (via USB or via Ethernet), the device may consider that the
new firmware is corrupt and therefore remain in the status screen to allow a new
firmware update. Please avoid bus / power interruptions until the new firmware has
been running for at least two minutes, as they may lead to the above situation (in such
case, please disconnect and connect Z41 once more to load the firmware again, and
ensure that there are no further interruptions for at least two minutes)
.
