KNX USB Interface 312.1

The KNX USB Interface 312.1 is a data interface between a PC or laptop and the KNX installation bus.

The device can be used as a programming interface for ETS® Software and supports KNX Long Frames. Long telegrams enable a faster download to devices that support these telegrams, and it is necessary for KNX Security.

The LEDs on the device indicate the operating status and communication errors on the bus. The USB connector (USB C) is galvanic isolated from the KNX bus

 

The KNX USB communication is based on HID and cEMI telegram coding according to the KNX specification. To integrate the KNX USB interface in applications running on Windows or Linux the cross-platform SDK kDrive is available from Weinzierl.

In addition to the telegram interface via cEMI, the KNX USB Interface 312.1 includes a complete KNX Stack with communication objects and BAOS protocol V2. Thus, the device offers the possibility to extend devices with USB connection (e.g. boards with embedded Linux) to full KNX devices, which can even be programmed with the ETS.
