PLC-HF15000L Expand Serial Command Functional Specifications 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.

Expand Serial Command Functional Specifications
11/105
�
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.
