Attention

If a command is transmitted after the lamp 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.

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

If a command cannot be executed, an “ER401” response is sent from the projector to the computer.

If an invalid parameter is sent, an “ER402” response is sent from the projector to the computer.

ID transmission in RS-232C supports ZZ (ALL) and 01 to 64, as well as 0A to 0Z groups.

If a command is sent with a specied ID, a response will be sent to the computer only in the following cases.

It matches the projector ID

ID setting is set to ALL and [RESPONSE(ID ALL)] is [ON]

ID setting is set to GROUP and [RESPONSE(ID GROUP)] is [ON]

STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
