Attention
The projector cannot receive any command for 10 seconds after the lamp is switched on. Wait 10 seconds before sending
z
a command.
If sending multiple commands, check that a response has been received from the projector for one command before
z
sending the next.
When a command which does not require parameters to be sent, a colon (:) is not required.
