Data streaming from the computer will start with STX,
and proceed to command, parameter and end with
ETX.
Parameters can be added as necessary.
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.
z
Note
If an incorrect command is sent, the ER401 command will be sent from the projector to the personal computer.
