Operating instructions

Configuration Description Example
Devices in a
chain
The devices are connected in pairs using
single lines. These should be terminated at
the ends. This type of configuration can
only be made when the devices used have
separate input (reception) and output
(transmission) channels, such as The
VIDEOTEC DTRX1 and DTRX3
receivers..
The received signal is sent “clean” to the
next device. If one device is blocked,
communication is cut off to the devices that
follow.
The maximum total length is equal to the
number of lines multiplied by 1200m for
each stage.
Mixed
configuration
It is possible to set up mixed
configurations, always bearing in mind the
limits given above:
 each line can have a maximum length
of 1200m
 each line should be terminated at the
ends
the stubs should be very short (max 2m)
