8.1 FT
The L-Gate FT port is fully compatible to the parameters specified by LONMARK for this
channel. FT ports can also be used on Link Power (LP-10) channels. However, the L-Gate
does not provide the power supply for Link Power channels.
When using the Free Topology Segment feature of the FT, only one termination (Figure
113) is required and can be placed anywhere on the free topology segment. Instead of
building the termination, one can order the L-Term module (LT-33) from LOYTEC, which
can be used to properly terminate the bus.

Figure 113: FT Free Topology Termination
In a double terminated bus topology, two terminations are required (Figure 114). These
terminations need to be placed at each end of the bus. Here, also L-Term modules can be
used at either end.
