Operation Messages
Operation messages are constructed using the following format:
Header is always
EFBE
h (byte 1 =
BE
h and byte 2 =
EF
h)
Type is always
03
h for Operation Messages
Size is always
0019
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.
