A **MA Network Processing Unit (NPU)** is for [parameter expansion](/grandma2/key_so_parameter_expansion/) and to add DMX ports in a network solution.

It is a 19" 3 Unit rack mount processor.

It got 8 female DMX ports and 1 female etherCON connector for network.

It cannot function as a standalone unit. It has to be connected to a session to do anything.
