4. Notes for Communication
4.1. The projector command is defined one command/one line that starts “C” and ends carriage
return (0x0D).
4.2. The projector starts decoding after the carriage return.
4.3. There are two types of command, functional execution commands and state read commands.
Example of Functional Execution Command: “C05” [CR]
Example of State Read Command: “CR0” [CR]
4.4. It clears information of accepting buffer as following terms.
1. When a projector receives LF (0xoA) or EOF (0x1A)
2. When it takes more than one second to receive on e command
(Until the projector receives the carriage return after the projector receives the first data)
4.5. When control command pipelining, after the response, wait interval of time as below.
1. COMMAND such as ”VOLUME +/-“!100ms
2. Other COMMAND!500ms
4.6. Wait at least 500 ms after the response, when status read command pipelining.
4.7. Do not issue any command before the Response.
When there is no response after 5 seconds, issue next command.
4.8. It takes about 7 seconds for internal initialization after plugging in AC. During this time, it
cannot process command. Do not issue any commands.
4.9. 7 seconds after Power ON from Standby, even when a projector receives a command, a
computer receives acceptable response, but it does not execute for internal initialization and
lamp lighting process. However, Status Read Commands are executed after 500ms when
they receive acceptable response.
4.10. About performance during processing count down or cooling down.
When a projector receives After Stand By or Power ON, Even when a projector receives a
command, a computer receives response to accept the command, but it does not execute
for internal initialization and lamp lighting process. However, Status Read Commands
are executed.
4.11. About performance when changing INPUT.
After receiving INPUT switching command, when receiving commands between 5 seconds
from starting the switching to completing the switching, a computer receives acceptable
command, but it is not executed.
However, status read commands are executed after a computer receives response to
accept the command, after 500ms.
4.12. Response for Status Read Command after accepting has different characters.
See ”Status Read Command Table”.
4.13. Characters for commands must be Capital (A - Z).
