The Planar Image Hub X Indisys Rack-mount Extensity processor is designed to provide additional expansion connecting to MultiCrop X or Image Master X.  Its uses may vary on the number of source inputs, often one to four added per wall. The modular processing system is managed over a private Ethernet network giving supervisory flexibility in setting and changing image layouts. Different video walls can be mixed into one system. Remote displays or smaller video walls can be added to the system. The rack-mounted processors work effectively with rack-located sources in the command room.
