Welcome to Beoworld !
The Beolink 1000 will operate the Beomaster 3300 but the remote functions of
the Beogram 4002 can only be used if connected to a Beomaster 2400-2.
The Beogram 4002 uses a very early (and simple) version of datalink that is not
compatible with the later version found in the Beomaster 3300 etc..
