Product Description
Ordering KeyD 3212 4000
Dupline®transmitter with mul- tiplexing function for multi- plexed transmission of analog signals. Applicablefor trans- mitters and display with ana- log inputs and built-in demul-
tiplexer (type D 6369 6475 or D342961..). Increasesthe 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 multiplexedanalogmodules 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 onthechannel groups they are coded for. The time untilthesame modulesex- changedataagain depends on the setting of the selector switchatthefrontofthe 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 with4 or 3 sequences are installed.
