To control the projector from a personal computer, com-mands must be input through communication software, based on the format and satisfying the commu-nication conditions shown below.Pin assignments and signal namesCommunication conditions (factory setting)Basic formatTransmission from the computer begins with STX, then the ID, command, parameter, and ETX are sentin this order. Add parameters according to the details of control.NOTE* If a wrong command is received, the projector will send an ER401 command to the computer.* If a wrong parameter is received, the projector will send an ER402 command to the computer.CAUTION* 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 com-mand. * Additional time is sometimes required for response due to processing inside the projector. Set the time-out period for command response to 10 secondsor more.D-sub HD 9-pin, femaleNo.12345No.6789Signal name-TXDRXD-GNDSignal name-CTSRTS-DescriptionNCSend dataReceive dataNCGroundSignal nameConnected internallyConnected internallyConnected internallyNC6159Signal levelSynchronization m ethodBaud rateParityCharacter lengthStop bitX parameterS parameterRS-232C-compliantStart-stop synchronization9,600 bpsNone8 bits1 bitNoneNoneCable specifications
