synchronisation of the device during the start-up. Once it reaches 100%, the

Status page will disappear and the Menu page will come up.

The “Ethernet” box shows the IP address assigned to Z41, provided that an

Ethernet cable has been attached (6) and the network is running a DHCP

server.

Last, the “SW Version” box shows the version of the application program

currently loaded to the device.

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 brief press on the programming button (2) will make the device enter the

programming mode. The programming LED (3) will then light in red. On the contrary,

if this button is held while the device gets connected to the bus, Z41 will enter the safe

mode. In such case, the programming LED will blink in red colour.

Connectors (5) and (6) are provided for firmware updates (see section 1.3.1) and most

likely for enhanced functionality such as remote accesses to the device.

For detailed information about the technical features of Z41, as well as on security and

installation procedures, please refer to the device Datasheet, included within the

device packaging and also available at www.zennio.com.

1.3.1 FIRMWARE UPDATES

Z41 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 may consist in two phases:

Downloading the new application program (from ETS),

Downloading the new firmware.
