This document describes the Projector Management Protocol between the Projector and a Computer (Host). The Protocol is
based on a ASCII commands. By using this protocol a Host will be able control the projector on a physical link.

The physical link is not defined in this document. Therefore the protocol can either be implemented on top of  RS-232, USB,
Ethernet or other forthcoming communication methods.

The Function is grouped in four different function types:
