The “Software” box will show empty in absence of an application program. In
general, it will indicate if the download software is correct (“OK”) or if it is
found to be corrupt due to download issues (“ERROR”).
The “Sync” box shows, as a percentage, the progress of the internal
synchronisation of the device during the start-up. Once it reaches 100%, the
Status page will disappear and the Menu page will come up.
Last, the “SW Version” box shows the version of the application program
currently loaded to the device.
The “Ethernet” box shows the IP address assigned to Z41 Pro, provided that
an Ethernet cable has been attached (7) and the network is running a DHCP
server.
The Status page will also show up during bus failures in case the external power (12-
24-29v) is not interrupted.
Note: although the device will not turn functional until it is powered with the external
supply, the KNX bus power should be enough to perform downloads from ETS
(application program, group addresses, etc.).
A short press on the programming button (5) will make the device enter the
programming mode. The programming LED (6) will then light in red. On the contrary,
if this button is held while the device gets connected to the bus, Z41 Pro will enter the
safe mode. In such case, the programming LED will blink in red colour.
Connectors (7) and (9) are provided for firmware updates (see section 1.3.1) and
remote accesses to the device.

and installation procedures, please refer to the device Datasheet, included within the
device packaging and also available at www.zennio.com.
