1 Product Description
The KNX USB Interface KSI-01U provides a bi-directional data connection between
USB and KNX TP. PCs can be connected via USB and the bus system is galvanically
isolated. KSI-01U establishes access to all bus devices for commissioning,
addressing, setting parameters, visualization, protocolling, and diagnostic
operation. Operational states are shown by LEDs. KSI-01U is supplied by both KNX
TP and USB. No external power supply is necessary.
With the ETS (or compatible commissioning tool) KSI-01U works as the KNX
programming interface having no KNX communication objects for itself. Due to HID
profile support no specific USB driver is required. USB suspend mode is supported.
The protocol used for communication between interface and host is the flexible
“cEMI” protocol.
The connection between KNX and a PC with standard software (like ETS, EITT, also
in Raw Frame operating mode) or other software is handled by the Falcon driver.
KSI-01U supports extended frames and long messages with up to 220 byte APDU
length. Easy software handling is ensured. For specific diagnostic applications like
EITT, KSI-01U supports the "Raw Frame" operating mode.
