*1 When transmitting a command which does not need a parameter, an operator (E) and parameter are not necessary .
Attention
 fIf a command is transmitted after the light source starts illuminating, \
there may be a delay in response or the command may not be 
executed. T
ry sending or receiving any command after 60 seconds.
 fWhen transmitting multiple commands, be sure to wait until 0.5 seconds h\
as 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
 fIf a command cannot be executed, the “ER401” response is sent from the projector to the computer
. fIf an invalid parameter is sent, the “ER402” response is sent from the projector to the computer
. fID transmission in RS-232C supports ZZ (ALL) and 01 to 06. fIf a command is sent with a specified ID, a response will be sent to the computer only in the following cases. gIt matches the projector ID gThe projector’
