Notes for communication

3.1
Expand Serial Command is defined as a single command per line that starts with "C" and ends with
carriage return (0x0D).
3.2
When a projector receives carriage return (0x0D), it starts decoding.
3.3
There are two types of commands; the Functional Execution Command and the Status Read
Command.
0û Example of Functional Execution Command:"CF_BRIGHT_032" [CR]
0û Example of Status Read Command: "CR_BRIGHT" [CR]
Note) "_" indicates a space
3.4
It clears the information of buffer in the conditions bellow:
0û When the projector receives LF (0x0A) or EOF (0x1A).
0û When it takes more than one second to receive a single command.
(Until receiving the carriage return after the reception of the first data.)
3.5
The projector processes commands and returns responses within a few ms to 8000 ms after the
reception of the command.
When several commands are issued in succession, do not send another command unless the
response to the previous command has been returned; need to confirm that the processing of the
current command has been completed and returned the response before sending another
command.
PC → Projector
Projector → PC
Note) When the computer sends another command before the previous response has been
returned, the projector may not operate properly. In case the current command processing has not
been completed, another command process cannot be accepted by the projector.
