This was an external unit, designed for the CD32 which plugged into the keyboard port. It was designed to allow the CD32 to be controlled from another Amiga and act as an FMX box using the Scala EX software. It also contained a keyboard port, so a keyboard could still be used with the CD32. At this time, it is uncertain what the difference between the Communicator 1 and the Communicator 2 is.
