3 Notes for Communication
・ The projector command is defined as a single command per line that starts with “C” and ends
with carriage return (0x0D).
・ When the projector receives carriage return, it starts decoding.
・ There are two types of commands: Functional Execution Commands and Status Read
Commands.
Example of Functional Execution Command: “C05” [CR]
Example of State Read Command: “CR0” [CR]
・ Projector clears the information of buffer in the cases below:
1) When the projector receives LF (0x0A) or EOF (0x1A).
2) When it takes more than one second to receive a signle command.
(Until the projector receives carriage return since it has received the first data.)
・ When executing the command pipelining for Functional Execution Commands, wait the interval
of time as below after the response.
1) [ZOOM UP/DOWN] [FOCUS UP/DOWN] [LENS SHIFT UP/ DOWN/ LEFT/ RIGHT]
Commands 100ms
2) Other Commands 500ms
・ When executing the command pipelining for Status Read Commands, allow at least 500ms after
the reception of the response.
・ Do not issue any command before receiving the response except when there is no response for
5 seconds.
・ Projector takes about 7 seconds for the internal initialization after plugging in AC until it moves to
Standby mode. During this time, the projector cannot process commands. Do not issue any
command.
・ For 7 seconds after executing Power ON operation in Stand-by mode, the projector receives a
command and returns the response but does not execute it due to the internal initialization or
lamp processing. However, Status Read Commands are carried out after 500ms when receiving
the response to Power ON command.
・ The operation during Countdown process and after Cooling Down:
When receiving a command during Countdown process after Power ON or Cooling Down
process after Power OFF, the projector returns the response but does not carry it out. However,
Status Read Commands are carried out.
・ The operation of Input switching:
Projector takes 5 seconds to switch inputs after receiving the command. When it receives
another command during this process, the command function is not executed. However, Status
Read Commands are carried out after 500ms since it receives the response to Input switching
command.
・ The number of characters of the response to Status Read Commands depends on commands.
・ Characters used for commands must be all Capital (A -Z).
