Appendix

The serial connector which is on the connector panel of the projector conforms to the RS-232C interface 
specification, so that the projector can be controlled by a personal computer which is connected to this connecter.

Basic format

 

The projector can not receive any command for 10 seconds after the lamp is switched on. Wait 10 seconds 
before sending the command.

 

If sending multiple commands, check that a response has been received from the projector for one 
command before sending the next command.

 

When a command which does not require parameters to be sent, the colon (:) is not required.

 

If an incorrect command is sent from the personal computer, the ER401 command will be sent from the 
projector to the personal computer.
