-When Projector receives carriage return code, it starts decoding.
-There are two types of command, Functional Execution Commands and State Read Commands.
Example of Functional Execution Command: “C04” [CR]
Example of State Read Command: “CR0” [CR]
-In the following cases, the data in the receive buffer is cleared.
・ When Projector receives LF (0x0A) or EOF (0x1A9).
・ When it takes more than 1 second to receive single command.
(More than 1 second from the first data to carriage return (0x0D)
Projector receives.)
-When control commands are pipelined, the following time intervals should be allowed after
receiving a response.
・ [Volume+/-], [ZOOM UP/DOWN], [FOCUS UP/DOWN], [LENS SHIF
UP/DOWN/LEFT/RIGHT] command -> 100ms
・ Other commands -> 500ms
-When Status Read Command pipelining, allow at least 500ms of interval time after receiving a
response.
-Do not issue any command before receiving a response; this is not the case when no response is
returned for 5 seconds
-It takes about 7 seconds for internal initialization after plugging in AC. During this period,
commands are not processed. Do not issue any commands.
-When starting POWER ON from the STANDBY status, it takes 7 seconds for intarnal
initialization and lamp lighting process. During this period, commands are accepted with OK
responses but the functions are not executed. However, Status Read commands are carried out
500 ms after OK response to Power ON command is received.
-About the behavior during Count Down and Cooling Down operation;
In the period of the Count Down operation after Power ON or Cooling Down after Power OFF,
the response to accept the command is returned, but it is not carried out except for Status
Read command.
-About the behavior during switching Inputs;
It takes 5 seconds to switch Inputs after receiving the command. During this period, even if it
receives another command, it does not carry it out although it returns the response for
acceptance. However, Status Read commands are carried out 500 ms after OK response to
Input switcing command is received.
-The number of characters for the returned value when Status Read command is successfully
received depends on commands. Please see the details and the table described in “7.3 Status
Read Command” section.
-Characters for commands must be in uppercase (A - Z). Those in lowercase can not be used.
