Digital Projection LIGHTNING 10sx, User Manual

Page: 100 / 151

Using an appropriate RS232 interface (see D—19, Cables & Connections) the
projector can be used in conjunction with a third party switching device. Currently
‘Extron System 8’ and ‘Extron System 10’ are compatible with the projector.
The projector and external switching device communicate at RS232 levels using the
following protocols:-
Data Rate: 9,600 baud
Data bits: 8
Stop bits: 1
Parity: None
Handshake: None
At present, an external switcher will allow you to control the lamp power, picture
mute and channel change functions. Messages transferred to and from the projector
are made up as a series of ASCII coded hexadecimal characters formed into
message packets using the structure below:-
Header Data Length Data Checksum
Header Represents data type according to the table below.
Data Length Will indicate the amount of variable length data to follow, in
bytes, not including the checksum.
Data Variable length string of characters.
Checksum A checksum of XX will indicate that the checksum should be
ignored and the message treated as correctly received.
Header Message Data Meaning
04 Lamp Power XX Change lamp power to specified value.
00 = minimum power and FF = maximum.
07 Picture Unmute - Unmutes the Picture.
