The KNX-USB interface enables communication between the KNX bus and a computer for
programming and monitoring devices on the bus by using the ETS program (version 5.5
or newer).
Furthermore, the KNX-USB interface can work in the bus logging mode, in which the history
of events generated on the KNX bus is saved to the interface non-volatile memory. The KNX-
USB Soft program allows you to enable / disable the bus logging mode and manage the
interface memory. Information saved in the KNX-USB interface memory allows you to
reproduce the telegram traffic on the KNX bus in off-line mode.
You can download the "KNX-USB Soft" program from www.satel.eu.
1. Features
Communication with the KNX bus via integrated bus connector.
Power supply from the KNX bus or from the computer USB port.
Galvanic isolation of the KNX system and computer.
Data transmission between the interface and the computer acc. to USB 2.0 standard.
LEDs indicating the device status.
Easy to connect and use.

terminal for connecting the KNX bus.
3. Connecting
1. Using the connection terminal, connect the KNX bus cable to the interface (Fig. 3).
2. Use the included USB cable to connect the computer USB port to the interface mini USB
port. The device will be automatically detected and installed in the computer's operating
system (Microsoft Windows). In the ETS program, the interface will be added to the list
of devices connected to the bus (Bus \ Connections \ Interfaces), where you can change
its individual address.
4. KNX-USB Soft program
The KNX-USB Soft program allows you to switch the KNX-USB interface to the bus logging
mode, in which the log of events generated on the KNX bus is saved to the non-volatile
memory of the device. All events are saved to the memory, which enables the bus to be
monitored in the same way as in the “Bus monitor” function of the ETS program.
The KNX bus power loss and restore events are also saved to the non-volatile
memory of the KNX-USB interface. The history of these events can be restored
by exporting data from the interface memory to a CSV or XML file.

SATEL KNX-USB 3
If several KNX-USB interfaces are connected to the computer, the KNX USB Soft
program will select the first one that is not used by another program.
In the bus logging mode, the interface does not support communication with the ETS
program.
After switching to the bus logging mode, you can disconnect the interface from the computer.
For protection against power failure, you can connect a power bank to the mini USB port
of the interface. If a bus power failure occurs, the interface will remain in the bus logging
mode instead of being shut down, and the bus loss and restore events will be saved to the
interface non-volatile memory.
A history of up to 350,000 events can be saved to the non-volatile memory of the
KNX-USB interface (the value was calculated for a telegram type 1.001 Switch).
Reaching this value does not stop logging. Information about events with the oldest
date is overwritten with information about events that are currently generated on the
KNX bus.
A power loss turns off the bus logging mode.
The interface powered from the KNX bus does not charge the energy bank connected
to it.
In order to restore data that are saved in the non-volatile memory of the KNX-USB interface,
they must be exported to a CSV (Microsoft Excel format) or XML (ETS program format) file.
If you want to change the separator used in the CSV file, you can do it in the Windows
“Control Panel”.
