3 Introduction to Functions
3.1 Indicators
HBS indicator: if the communication between S2S KNX Gateway and the
unit is normal, the HBS indicator will be on constantly; if there is communication
error between S2S KNX Gateway and the unit, the indicator is off.
RUN indicator: if the S2S KNX Gateway works normally, RUN indicator
ashes.
Prog. indicator: when the indicator is on, it means the S2S KNX Gateway
is under programming status; when the indicator is off, it means the S2S KNX
Gateway quits programming status.
3.2 Functional Dial Codes
Setting area of S2S KNX Gateway DIP switch is located inside the product.
The first knob of functional dialer S1 is used for setting the master and
slave HBS equipment, after altering the setting of master and slave HBS

equipment, it will come into force only after re-energizing the gateway. When the
rst bit is in number end, it is set as master HBS equipment, when the rst bit is
in ON end, it is set as slave HBS equipment.
The second bit of functional dialer S1 is reserved.
master HBS equipment slave HBS equipment
Remark: the default S2S KNX Gateway is master HBS equipment. When
there is multiple equipment in the HBS bus bar, it is recommended to set the S2S
KNX Gateway as slave equipment, the wired controller as master equipment.
