Synchronizer Module
Type D 3212 4000
Dupline
transmitter with mul-
tiplexing function for multi-
plexed transmission of analog
signals. Applicable for trans-
mitters and display with ana-
log inputs and built-in demul-
tiplexer (type D 6369 6475 or
D 3429 61..). Increases the
transmission capacity of a
Dupline
system to max. 112
analog signals with 12 bit re-
solution.

General Specifications
Mode of Operation
Synchronizer for control of
multiplexed analog modules
in H4-housing.
D 3212 continuously trans-
mits binary values (addresses)
on channels A1 to A4 as
shown in the chart below.
Every binary value enables
the respective transmitters,
receivers and displays in a
system that uses multiplexed
modules.
First, the transmitters/receivers
on address 0 exchange data.
In the following pulse train the
transmitters/receivers on ad-
dress 1 exchange data etc.
With this all modules set up to
the same multiplex address
exchange data for one pulse
train on the channel groups
they are coded for. The time
until the same modules ex-
change data again depends
on the setting of the selector
switch at the front of the
D 3212.The selector switch
defines the number of multi-
plex addresses that are gene-
rated on channels A1 to A4.
Note: Multiplexed modules
must not be used in systems
where channel generators
with 2 or 3 sequences are
installed.
