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 with2 or 3 sequences are installed.
