Network topology
Linear bus
Active bus termination at both ends. A total length of all
branches
of
up
to
6.6 m
is
only
permissible
with
transmission rates
≤
1.5 Mbit/s. No branches should be
used with 12 Mbauds
Medium
Shielded twisted-pair cable
Number of stations
32 stations per segment without repeaters. Up to 127
stations possible with repeaters.
Connector plugs
Preferably 9-pinSub-D connectors.
7.2.3.2
Cable parameters
The bus cable to be used for FI 830F is specified in DIN 19245/EN 50170 as line type
A and can be used according to the following table:
Parameters
Line A
Characteristic impedance in
Ω
135 ... 165
Capacitance per unit length (pF/m)
< 30
Loop resistance (
