Attention
 z 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.
 zWhen 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
 z If a command cannot be executed, a “ER401” response is sent from the projector to the computer
.
 zIf an invalid parameter is sent, an “ER402” response is sent from the projector to the computer
.
 zID transmission in RS-232C supports ZZ (ALL) and 01 to 64, as well as 0A
 to 0Z groups.
 zIf 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]
 zSTX and ETX are character codes. STX shown in hexadecimal is 02, and ETX shown in hexadecimal is 03.
▶■ When multiple projectors are controlled
▶z
When multiple projectors are all controlled
When 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).
▶zWhen multiple projectors are all controlled by group unit
When 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).
Note
 z There will be no response if 2 or more projectors have [RESPONSE(ID 
ALL)] set to [ON].
 zT

here will be no response if 2 or more projectors of the same group have [RESPONSE(ID GROUP)] set to [ON].
 zWhen setting multiple groups, set [RESPONSE(ID 

ALL)] to [ON] in only one projector in each group.
