When commands are sent to projector, the projector will respond in the following manner. 
 
1) Normal command receiving 
When the command is in the proper format and correct communications has been established 
between the controlling device and the projector, the projector will reply with the response 
information. 
 
2) Command receiving error (NO Response) 
If no response is transmitted from the projector, then check the communication settings and the 
cable configuration.  The command string must start with a [STX] Start of Text message.  This 
will alert the projector to start receiving commands.  An [ETX] End of Text message must end 
the command string or the projector will not execute the command. 
 
3) Command Receiving Error [STX]ER401[ETX] 
If this error is transmitted from the projector, the projector did not recognize the command that 
was sent from the control device.  Check the command list to ensure that the command is valid, 
and the characters are capitalized. 
 
4) Command Receiving Error [STX]ER402[ETX 
If this command is transmitted from the projector, the projector did not recognize the parameter 
that was sent from the control device.  Check the command list for the appropriate parameter 
data that is to be sent with the appropriate command to the projector. 
 
5) Query Reponses 
If a command such as [STX]Q$L[ETX] Query Lamp Operation Time is sent.  The projector will 
send the reply of [STX]Q$L:0000[ETX].  Parameter information will be replied only in the case of 
a Question type command.  Check the command list for the specific information.
