3． Notes for communication
・ Expand Serial Command is defined as a single command per line that starts with "C" and ends with
carriage return (0x0D).
・ When a projector receives carriage return (0x0D), it starts decoding.
・ There are two types of commands as below:
Example of Functional Execution Command:"CF_BRIGHT_032" [CR]
Example of Status Read Command: "CR_BRIGHT" [CR]
Note) "_" indicates a space
It clears the information of buffer in the following cases:
・
- 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)
・ The projector processes the command and returns the response within a few ms to 8000 ms after
the reception of the command. When several commands are sent 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.
Note) when the current command processing has not completed, another command process can
not be accepted by the projector
・ 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 as listed
below:
