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.
�
Example of Functional Execution Command:”CF_BRIGHT_032” [CR]
�
Example of Status Read Command: “CR_BRIGHT” [CR]
Note) “_” indicates a space
3.4
It clears the information of buffer in the conditions bellow:
�
When the projector receives LF (0x0A) or EOF (0x1A).
�
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.

returned, the projector may not operate properly.
Note)
When the current command processing has not been completed, another command
process cannot be accepted by the projector.
3.5.1
Normally it is less than 1000ms for the completion of receiving a command and returning the
response, but it takes more than 1000ms for some Functional Execution Commands (CF
commands) as listed below:

It takes about 8 seconds for the internal initialization after plugging in AC power.
During this time commands cannot be processed. Do not issue any command.
