Product Description
Ordering Key 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 or 3.5 BCD.

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.
