Description
USB-KNX Interface
The USB interface N 148/12 is an N-system DIN-rail
mounted device. The device can be connected to the
bus line parallel via the pressure contact system as well
as the bus terminal.
The USB interface N 148/12 enables with its built-in USB
socket a personal computer to be attached for
addressing, parameterising, visualising, logging and
diagnosis of bus devices.
With the USB interface it is possible to operate all bus
devices in the whole bus system.
The USB interface N 148/12, supporting long frames up
to 64 bytes, is compatible to USB 2.0 and USB 3.0. The
transmission rate between the PC and the interface is
12 Mbit/s maximum.
Inside the device the USB socket is isolated from the
KNX-bus.
The connection between the USB interface and the PC
is arranged between the USB socket of the USB
interface and any USB socket of the PC or a connected
USB hub.
The required USB cable (normal USB cable for PC
peripherals with one USB plug type A and one USB plug
type B) is not a part of the shipment but has to be bought
separately, for example, at authorized computer stores.
The power supply of the USB interface N 148/12 is
carried out via the USB cable by the PC. When the
interface is not connected to the PC or the PC is not
switched on the interface N 148/12 is not active and
cannot be accessed from the bus.
