*1 When transmitting a command which does not need a parameter, an operator (E) and parameter are not necessary.
Attention
ff If a command is transmitted after the light source starts illuminating, there may be a delay in response or the command may not be executed. Try sending or receiving any command after 60 seconds.
ff When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the projector before sending the next command. When transmitting a command which does not need a parameter, a colon (:) is not necessary.
Note
ff If a command cannot be executed, the “ER401” response is sent from the projector to the computer. ff If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.
ff ID transmission in
ff If a command is sent with a specified ID, a response will be sent to the computer only in the following cases. gg It matches the projector ID
gg The projector’s [PROJECTOR ID] (x page 69) is [ALL]
ff STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
