The USB interface, flush-mounted allows linking to a PC
for addressing, programming and diagnosis of KNX
components with USB1.1 or USB2 interfaces.
The device has an integrated bus coupler and is
connected to the bus with a bus connecting terminal.
Power is supplied entirely from the connected PC via
the USB interface. The USB interface is recognised by
the KNX system when the USB cable is plugged in. The
device is programmed with the physical address locally
only via the connected PC and therefore does not have
a programming button or a programming LED.
The firmware for the USB interface can be updated via
a PC and is therefore future-proof for any later
standards.
The USB interface is provided for screw assembly in a
size 60 installation box.
For combination with the central plate for telephone
socket-outlet TAE (e.g. Art. no. 2960.., 2979.., 2978..,
2928.., 2938..).
|Common covers for 230 V devices and low-
voltage devices are allowed for flush-mounted
switches and socket-outlets with screwless
terminals. Observe the relevant regulations.
