Command/response table for advanced instructions

(for the Windows-based control program)

Data downloads/uploads are initiated by sending a series of hex commands to the
host RS-232 port of the System 7 switcher. The Windows-based control program
uses these commands mainly to load and save driver data and system
configuration settings. See page 3-6 for information on projector control memory.
