Chapter 6 Appendix — Technical information206 - ENGLISHAttentionf If a command is sent after the light source starts lighting, there may be a delay in response or the command may not be executed. Trysending or receiving any command after 60 seconds.f When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the projector beforesending the next command. When transmitting a command which does not need a parameter, a colon (:) is not necessary.Notef If a command cannot be executed, the “ER401” response is sent from the projector to the computer.f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer.f ID transmission in RS-232C supports ZZ (ALL) and 01 to 64, as well as 0A to 0Z groups.f If a command is sent with an ID designated, a response will be sent to the computer only in the following cases.g It matches the projector IDg ID is designated as ALL and [RESPONSE(ID ALL)] is set to [ON]g ID is designated as GROUP and [RESPONSE(ID GROUP)] is set to [ON]f STX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.When multiple projectors are controlledWhen multiple projectors are all controlledWhen controlling multiple projectors together via RS-232C, perform the following settings.1) Set a different ID for each projector.2) Set [RESPONSE(ID ALL)] to [ON] in only one projector.3) Set [RESPONSE(ID ALL)] to [OFF] for all other projectors set in Step 2).When multiple projectors are all controlled by group unitWhen controlling multiple projectors by group unit via RS-232C, perform the following settings.1) Set a different ID for each projector.2) Set [RESPONSE(ID GROUP)] to [ON] in only one projector.3) Set [RESPONSE(ID GROUP)] to [OFF] for all other projectors set in Step 2).Notef There will be no response if two or more projectors have [RESPONSE(ID ALL)] set to [ON].f There will be no response if two or more projectors of the same group have [RESPONSE(ID GROUP)] set to [ON].f When setting multiple groups, set [RESPONSE(ID ALL)] to [ON] in only one projector in each group.Cable specification1 NC NC 12 23 34 NC NC 45 56 NC NC 67 78 89 NC NC 91 NC NC 12 23 34 NC NC 45 56 NC NC 67 78 89 NC NC 9When connected to a computerProjector( terminal)Computer(DTE specifications)When multiple projectors are connectedProjector 1(terminal)Projector 2(terminal)
