Repeater
If the maximum numbers of nodes (max. 64) or total cable distance are exceeded, a repeater
can be added to interconnect two or more network segments.
A repeater can also be used to convert from a free topology network to a bus topology
network. This can be useful when e.g. making network connection to remote PTZ cameras.
Note that only one Repeater should be placed in series between any two nodes in a segment

Validated Cables and Cable Types
1)
Any cable that meets the TIA/EIA 568A standard, is suitable for LON
®
Networks.
2)
Standard originally specified by the National Electrical Manufacturers Association (NEMA).
3)
The J-Y(St)Y cable is normally only available in Europe.
4)
In order to comply with EMC/EMI standard EN 50130-4, shielded cable must be used.
5)
With shield.
