1. General Description
The KNX TP Media Coupler LC100 provides a bi-directional data connection between two KNX TP lines
or areas and works as a KNX line/area coupler in the KNX network. KNX TP main line and KNX TP subline
are coupled having a galvanic isolation in between. Extended frames and long telegrams with up to
240 bytes APDU length are supported.
Using the TP Coupler application, LC100 can be used as KNX TP line coupler to connect different TP
lines, but also as a KNX TP area coupler to connect different TP areas or installation systems via a TP
Backbone. Telegram filtering is accomplished according to the installation place in the hierarchy
(Physical[ly addressed] Telegrams) and according to the built in filter tables for group communication
(Group [oriented] Telegrams). For detailed diagnosis, all operational modes/states are shown by a duo-
LED display. Programming on main line from the subline can be suppressed. Number of repetitions on
both KNX TP lines can be reduced.
Using the TP Repeater application, LC100 is able to extend a KNX TP line providing unfiltered data
transfer and galvanic isolation between segments. Up to four line segments can form a single KNX TP
line by connecting three LC100 line repeaters. Each line segment requires its own KNX power supply
unit.
To ease commissioning and troubleshooting, special routing/repetition/confirmation ETS settings and
a configurable Manual Function for short-time telegram filter switch-
off are available. E.g. “transmit
all group telegrams” can be activated by a single button press. After
the set time period, LC100
switches back to normal operation automatically. Another feature to increase the data throughput is
the ability to send IACKs on own telegrams.
