1INTRODUCTION
1.1 KIPI SC
KIPI SC is the solution from Zennio with KNX Secure for the interconnection of KNX
twisted-pair lines and Ethernet.It also provides a connection point for ETS to enable
programming (up to five parallel connections) and monitoring the KNX line via IP.
KIPI SC can synchronize the date and time with an NTP server in order to send this
information to the KNX bus and serve as the clock master of the installation.
To ensure the exchange of KNX data in both IP and TP medium, the KIPI SC has been
provided with KNX Secure. For detailed information about the functionality and
configuration of the KNX security, please refer to the specific user manual "KNX
Secure", available in the KIPI SC product section of the Zennio web portal
(www.zennio.com).
These are the most outstanding features of this device:
Maximum APDU length of 254 bytes.
Up to 5 parallel connections from ETS for programming and monitoring (via
group monitor).
No external power required.
High capacity buffer for the reception of telegrams from the Ethernet network.
4 lighting indicators (LEDs):two state indicators for the lines (bus and
Ethernet), one more IP factory reset indicator, and one additional indicator for
the programming mode.
Installation Clock master functionality, synchronized with NTP servers.
Heartbeat or periodical “still-alive” notification.

1.2 INSTALLATION
Figure 1. Element Diagram
Figure 1 shows a scheme with all the LED indicators and required connections. This
device does not require an external power supply, it is powered through the KNX bus.
To couple a KNX twisted-pair (TP) line and a LAN network, the KNX bus (6) and Ethernet
(1) cables must be connected. After the connection, the device can be conveniently
mounted on the DIN rail by the usual procedure
The programming button (8) shown in
Figure 1 programming button (8) may be pressed to set KIPI SC in programming mode.
After a short press, the programming LED (7) will light in red.
Note: if the programming button is held while plugging the device into the KNX bus, the
device will enter into safe mode. In such case, the LED will blink in red every 0.5
seconds.
The behaviour of the additional LEDs and the factory reset button will be described in
sections 1.3 and 1.4.
For detailed information about the technical features of the device, as well as on security
and installation procedures, please refer to the device Datasheet, bundled within the
original packaging of the device and also available at www.zennio.com.

1.3 LED INDICATORS
KIPI SC incorporates four LED lights on the top of the device that make it easy to monitor
the status of the buses and to detect typical communication problems, as detailed next.
Figure 2 LEDs
KNX Line Status LED (TP): shows the status of the primary bus.
➢OFF: error or KNX line not connected or not powered.
➢ON (green) = TP connection OK.
Note: the update of the LED status can be delayed a few seconds after the
trigger event, e.g., after the disconnection of the main line.
Ethernet Line Status LED (IP): shows the status of the secondary bus.
➢OFF: error or IP line not connected.
➢ON (green): Ethernet connection OK
Programming LED:
➢OFF = normal operation.
➢ON (red) = programming mode active.
IP Factory Reset LED:
➢OFF: normal operation.
➢ON (red): factory IP is restored (300 ms active).

1.4 HARD RESET TO FACTORY DEFAULTS
If “IP Fact. Reset” button is pressed for three seconds, the device restores its default
parameters (obtain an IP address via DHCP server). Thus, if a device becomes
inaccessible on the local network due to the loss of its IP configuration, the device can
be located again. The default configuration will persist until a new download is made.
When a long press is detected, the associated LED will light up in red for 300 ms. After
this time, LED will switch off again.

2CONFIGURATION
After importing the corresponding database in ETS and adding the device into the
topology of the desired project, the configuration process begins by entering the
Parameters tab of the device.
2.1 KNX TO IP INTERFACE
KIPI SC interconnects a KNX bus and an Ethernet network (LAN).
On the other hand, KIPI SC can be allocated within the project topology in ETS, as any
other device. This step can be omitted when it is going to be used as interface, because
there is no need to modify the default configuration (see previous section). However,
when requiring to modify any property of KIPI SC, an individual address should be
assigned in order to download.
2.1.1 PROGRAMMER
KIPI SC can be used in ETS as a programming interface. In addition to an IP address,
they must be assigned a KNX individual address for this purpose.
Up to five simultaneous connections are allowed for performing downloads or for bus
monitoring (via group monitor).
Note: to detect the KIPI SC as a programmer in ETS, it needs to be connected to the
same IP network as the PC.
To use a device as a programmer simply select it in the ETS "Bus" tab under Connections
→Interfaces.

Figure 3. Selection of KIPI SC in the Bus Connections tab in ETS.
Or by selecting it at the bottom left after opening a project in ETS.
Figure 4. Selection of KIPI SC in a ETS project.
Important: If the KIPI SC is selected as the programming interface to program itself
it is recommended to first perform individual address download and then application
download, rather than complete download (complete download causes a device
restart and therefore communication with ETS is lost and the download is cancelled).
2.1.1.1 PROPERTIES
Once the desire Interface KIPI SC has been selected, its configuration will be carried out
in the “IP” panel of “Properties” tab in ETS:

Figure 5. IP Configuration
Obtain an IP address automatically1.KIPI SC will automatically acquire an IP
address whenever there is a DHCP server in the local network to which it is
connected.
Use a static IP address. The following properties must be set manually:
➢IP Address [0.0.0.0…255.255.255.255].
➢Subnet Mask [0.0.0.0…255.255.255.255].
➢Default Gateway [0.0.0.0…255.255.255.255].
Note: If a static IP is configured, it is important to make sure that no other device on the
network has this IP assigned to it and that it does not belong to the DHCP range
configured for the router, otherwise connection problems with the KIPI SC will be
observed.
In addition, the following information will be shown:
MAC Address.
1The default values of each parameter will be highlighted in blue in this document, as follows:
[default/rest of options].

Multicast Address [224.0.23.12]: IP address (reserved by the IANA
organization for the KNXnet/IP protocol) used by ETS in this case, for
discovering the available KNX-IP interfaces within the same network.
Once these properties have been entered an ETS programming is required to download
the configuration to the device.
2.1.1.2 PARALLEL DOWNLOADS
ETS offers the option to perform multiple parallel downloads within the same project.
This option is only available for connections via a KNX-IP router or a KNX-IP interface.
Certain conditions must be met:
Each download must be performed on a different line.
For each line, it is necessary to select one KIPI SC to perform the download.
Note: There is a restriction: parallel downloads are not available to download physical
addresses. When performing this type of downloads, the link device used by ETS is not
the one configured for the line but the general one.
This is configured in the line properties.
Figure 6 ETS parallel downloads configuration.
Note: once the connection has been selected, it will not be available for the other lines.

2.1.2 ADDICIONAL INDIVIDUAL ADDRESSES (TUNNELING ADDRESSES)
KIPI SC requires a specific individual address when acting as a programming interface
(tunneling) other than the address of the device itself. Up to five simultaneous
connections are possible, which implies that up to five different individual addresses must
be configured.
Although, by default, the physical address of KIPI SC is 15.15.255 and tunneling
addresses are 15.15.250, 15.15.251, 15.15.252, 15.15.253 and 15.15.254, all of them
can be configured in ETS after adding the device to the project, as shown in Figure 7:
Figure 7. Set tunneling addresses.
After the individual KIPI SC address has been set, the five tunneling addresses are
automatically set with consecutive values. This can be changer at any time.
Important: KIPI SC tunnelling addresses must not match any of the addresses set to
other devices on the system.

2.2 GENERAL
The only parameterizable screen available is “General”. All device functions can be
activate/deactivate from this screen.
ETS PARAMETERISATION
Figure 8. General.
Heartbeat (Periodic Alive Notification) [disabled/enabled]: incorporates a
one-bit object to the project (“[Heartbeat] Object to Send ‘1’”) that will be sent
periodically with value “1” to notify that the device is still working (still alive).
Figure 9. Heartbeat
Note: the first sending after download or bus failure takes place with a delay of
up to 255 seconds, to prevent bus overload. The following sendings march the
period set.
Synchronize Clock Master via NTP [disabled/enabled]: enables or disables
the “NTP” tab in the tree on the left. For more information, see section 2.3.
Note: This parameter must be enabled in the device that will be clock master
so that there is only one in the installation.
DNS Servers Configuration: numeric text fields to enter the IP address of two
DNS servers:
➢IP Address of DNS Server 1 and 2 [198.162.1, 198.162.2].

Note: The connection to the DNS server is necessary to ensure the correct
functioning of the NTP servers (see section 2.3). As long as there is no
connection to a DNS server, the date and time information will not be
synchronized.
2.3 NTP CLOCK
KIPI SC can be configured as the installation master clock, it will send the date and time
information to the rest of the devices of the installation. This information will be obtained
from an NTP server.
Please refer to the specific manual “NTP Clock” (available under the KIPI SC product
section at Zennio homepage, www.zennio.com) for detailed information about the
functionality and the configuration of the involved parameters.
