Operation messages are constructed using the following format:
Header

Type is always

h for Operation Messages
Size is always

h (byte 4 =
19
h and byte 5 =
00
h) i.e. 25 bytes after CRC
CRC can be set to
5858
h if you want the CRC to be ignored. However, the CRC
should ideally be calculated, as described in the
Titan Projector Series External
Control Protocol
.
Operation type is one of the following:
Set
01
h
Get
02
h
Increment
03
h
Decrement
04
h
Execute
05
h
Set
writes a value to the projector.
Get
reads a value from the projector.
Increment
and
decrement
increase or decrease a value by one unit.
Execute
executes the current operation (specific commands only).
Spaces in the example messages are for visual clarity and should not be sent as
part of the message.
Notes
The following pages contain
examples of some basic
Operation commands.
