Technical information

■■Basic format

Transmission from the computer starts with STX, then the ID, command, parameter, and ETX are sent in this order. Add parameters according to the details of control.

*1: When transmitting a command which does not need a parameter, a colon (:) is not necessary.

■■Basic format (with subcommands)

Same as the basic format

Sub command

Parameter (6 bytes)*1

(5 bytes)

Symbol “+” or “-” (1 byte) and setting

 

or adjustment value (5 bytes)

 

Operation (1 byte)*1

 

“=” (Set the value specified using parameter)

*1: When transmitting a command which does not need a parameter, the operation (E ) and parameter are not necessary.

Attention

zzIf 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.

zzWhen 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.

Note

zzIf a command cannot be executed, a “ER401” response is sent from the projector to the computer. zzIf an invalid parameter is sent, a “ER402” response is sent from the projector to the computer. zzID transmission in RS-232C supports ZZ (ALL) and 01 to 64, as well as 0A to 0Z groups.

zzIf a command is sent with a specified 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]

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