KNX USB Interface 312
The KNX USB Interface 312 is a data interface between a PC or laptop and the KNX installation bus. It can be used as a programming interface for ETS® Software Version 3 (or higher) and supports KNX long frames. Long telegrams enable a faster download to devices that can receive these telegrams.
The LEDs on the device indicate the operating status and communication errors on the bus. The USB connector is galvanic isolated from the KNX bus.
Notes for developers
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 includes a complete KNX Stack with communication objects and BAOS protocol V2. Thus, the device offers the possibility to extend devices with USB connection to full KNX devices, which can even be programmed by ETS.
