11.1 TP-1250
The TP-1250 uses transformers for galvanic isolation. The topology of a TP-1250 network
is a bus. Thus, both ends of the bus cable need to be terminated. LOYTEC recommends
using its L-TERM network terminators (LT-13) for network termination (see Figure 140).
If the collision-less backbone mode (recommended, default behavior) is disabled, the L-IP
TP-1250 ports are fully compatible to the parameters specified by L
ON
M
ARK
for this
channel (TP/XF-1250). If the collision-less backbone mode is enabled, proprietary channel
parameters are used. In this case no Neuron Chip based nodes or other nodes with standard
TP-1250 communication parameters are permitted on the same channel.
11.2 FT-10
The L-IP FT-10 ports are fully compatible to the parameters specified by L
ON
M
ARK
for this
channel. FT-10 ports can also be used on Link Power (LP-10) channels. However, the L-IP
does not provide the power supply for Link Power channels.
