Mode of Operation
The Dupline
repeater is used
to increase the distance in a
Dupline
network. Further-
more, it can be used as
"Power-booster" in sections
with several Dupline
supplied
units.
The repeater introduces a de-
lay of 1 Dupline
scan when
transferring pulses from se-
condary Dupline
to primary
Dupline
, while pulses from
primary Dupline
to second-
ary Dupline
are transferred
with a max. delay of 1 ms.
When using analog transmis-
sion including synchronizer it
is necessary to be cautious
due to the above mentioned
delay. In this case the analog
transmitter should not be
connected on the secondary
side. On the other hand the
synchronizer and the analog
receivers can be placed with-
out restrictions.
By application of the Dupline
repeater there are no prob-
lems when transferring the
functions of the master gene-
rator.
Concerning the numbers of
channels the repeater adjusts
itself based on numbers of
channels on the input side of
the Dupline
network.
The repeater has a built-in
channel generator function for
the secondary Dupline
. This
channel generator function
locks itself on to the function
of the channel generator on
the primary side.
