Termination Resistance
Connect the termination resistance connector to the first and last device connected to
the bus: CU, splitter or I/O module.
Caution
2-wire
Use unshielded wires of the cross-section of 0.75 mm .
2
The maximum total length per shaft is 600 m.
With multi-strand cables, always use a pair of wires which match
each other.
With a tow cable, consider the cable length too.
With special cables (to the cabin), use the neighbouring wires and
make sure that the nearest surrounding wires do not radiate
interference (power wire, video signal etc.).
Tip
Do not lead the bus close to power cables, especially in long-distance
sections.
Branch the bus to shorten the total length of sections.
Safety
The bus is electrically isolated from the telephone line circuits according to
the EN60950 standard requirements and its low voltage cannot cause any
electrical accident.
Caution
Find the 2-pin termination resistance connector between the main bus
connector and audio unit connectors (see the figure below).
By default, the termination resistance is connected (jumper mounted).
