Ekinex EK-BA1-TP Manual

Line/area coupler
Product code: EK-BA1-TP
S
TP1
KNX device with function of line/area coupler. It has to be
used in KNX installations for control of homes and buil-
dings.
Description
The ekinex EK-BA1-TP line/area coupler allows the cou-
®
pling of a KNX bus main line with a KNX bus secondary
line. The device provides the galvanic isolation between
the two connected lines. Thanks to its flexibility, the cou-
pler can be used as a line coupler to connect a secondary
line with a main line or as an area coupler to connect a
main line with a backbone line. The main task of the devi-
ce is filtering the traffic according to the installation place
in the hierarchy or according to the built-in filter tables
for group oriented communication. The device provides
support for long messages (up to 250 bytes) and a confi-
gurable pushbutton for the activation of special functions
which are helpful during installation, run time operation
and troubleshooting. 6 LEDs accurately display the bus
status on each line. This helps identifying common com-
munication problems due to bus load or retransmissions
on both lines. The device is powered by the KNX bus line
with SELV voltage 30 Vdc and does not require any auxi-
liary power supply.

Long press (3 sec)
- Switch to manual overwrite, configuration is done via
ETS
- Status LED main bus line red:
On: switch on manual overwrite
Off: switch to configured routing
Very long press (15 sec)
