3.2 FT-10
The L-Switch XP FT-10 ports are fully compatible to the parameters specified by
LONMARK for this channel. FT-10 ports can also be used on Link Power (LP-10) channels.
However, the L-Switch XP does not provide the power supply for Link Power channels.
When using the Free Topology Segment feature of the FT-10, only one termination is
required and can be placed anywhere on the free topology segment. In a double terminated
bus topology, two terminations are required. These terminations need to be placed at each
end of the bus.
LOYTEC recommends using its L-TERM network terminators (LT-13, LT-33 or LT-03)
for network termination (see Figure 9).

3.3 RS-485
The L-Switch XP RS-485 ports are fully compatible with the parameters specified by
TIA/EIA RS-485 for this channel. A maximum of 32 L-Switch XP RS-485 ports can be
connected to one channel.
The RS-485 ports support bit-rates between 300 kbps and 2.5 Mbps. When using bit-rate
auto-detection (see Section 4.2) the L-Switch XP checks for the following bit-rates: 0.61
kbps, 1.221 kbps, 2.441 kbps, 4.883 kbps, 9.766 kbps, 19.531 kbps, 39.0625 kbps, 78.125
kbps, 156.25 kbps, 312.5 kbps, 625 kbps, 1,250 kbps and 2,500 kbps. Standard Neuron
Chip compatible channel parameters with a channel priority of 4, but no node priority are
