Small system
–
A system consisting of up to 5 SimNet products and up to 7
meters (23’) total length (L) of SimNet cable including the
SimNet power cable.
In a small system you need the SimNet power cable with built in
termination (red disc on cable plug).
Connect the products in a daisy chain or use drop cables as
recommended in the introduction. A second termination is not
required.

Total network load and System Size Factor
As with all network systems some basic rules must be observed
in relation to the size of the network. The System Size Factor
determines the size of a SimNet network based on load and cable
length.
Note ! Because of the high data rate the network shall be terminated at
each end to match the characteristic impedance of the network
cable. Do not use more than two terminations or place the
termination(s) away from the network ends. If cables are
extended beyond the termination point, they are to be considered
drop cables to the network and the length is limited to 6 m (20’).
