CAUTIION
It may not be possible to send or receive commands for about 10 to 60 seconds when the lamp is first turned on. If this occurs, wait for 60 seconds, then
try sending or receiving again. When sending multiple commands, be sure to wait for at least 0.5 second after receiving a response from the projector
before sending the next command. Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for
command response to 10 seconds or more.
NOTE:
If a wrong command is received, the projector will send an ER401 command to the computer.
When sending commands without parameters, a colon (:) is not necessary.
