binary parameter data to the host.
Send/receive a segment (256 bytes) of data
(a segment relating to a single button)
Send 80 A6 ?? [256 bytes of data] Seg0 The host sends 256 bytes of
binary data to the System 7.
Receive 80 A7 ?? The System 7 sends 256 bytes of

(0 to 127 decimal).
The responses shown are ASCII.
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.
