Depending on the kind or the virsion of the host controller, operation may not be possible in some cases. • In the case of notebook type computers with a built-in pointing device such as a track ball, in some cases the built-in pointing device will have priority even if a mouse is connected and the mouse may not be selected. In such case, disable the built-in pointing device and change the BIOS setting (system setup) so that an external mouse can be selected. After changing the BIOS setting, perform the operations described in 1 - 3 above. Refer to the computer hardware manual concerning the BIOS setting. Also, some computers may not have a utility program to operate a mouse. Refer to the computer hardware manual.

Use the mouse cable provided or an optional mouse cable to make the connection. • In the case of notebook type computers with a built-in pointing device such as a track ball, in some cases the built-in pointing device will have priority even if a mouse is connected and the mouse may not be selected. In such case, disable the built-in pointing device and change the BIOS setting (system setup) so that an external mouse can be selected. After changing the BIOS setting, perform the operations described in (1) - (3) above. Refer to the computer hardware manual concerning the BIOS setting. Also, some computers may not have a utility program to operate a mouse. Refer to the computer hardware manual.Caution 1. Mouse functions (1) Turn off the main power switches of the projector and computer and connect the two units with the cable provided or an optional suitable commercially available cable. Disconnect the USB cable from the projector. (2) Turn on the main switch of the projector (the POWER indicator lamp will light green). (3) Press the INPUT button of the projector or the RGB button of the remote control and select the input where the computer is to be connected. (4) Turn on the computer power supply. (5) Start the mouse function. If the mouse has not been started, reboot the computer (soft reboot or reboot buttons). (6) Refer to page 10 concerning remote control operation.

30 Connection to the control signal terminal (continued) Requesting projector status (1) Send the request code ‘20H’ + ‘yyH’ from the computer to the projector. (2) The projector returns the response code ‘1xH’ + ‘yyH’ +data to the computer. Changing the projector settings (1) Send the setting code ‘3xH’ + ‘yyH’ +data from the computer to the projector. (2) The projector changes the setting based on the above setting code. (3) The projector returns the response code ‘1xH’ + ‘yyH’ +data to the computer. Using the projector default settigns (1) The computer sends the default setting code ‘40H’ + ‘yyH’ to the projector. (2) The projector changes the specified setting to the default value. (3) The projector returns the default value with the response code ‘1xH’ + ‘yyH’ =data. When a command sent by the projector cannot be understood by the computer (1) The computer sends the command code ‘3xH’ , ‘4xH’ or ‘4xH’ + ‘yyH’ +data to the projector. (2) When the command sent by the projector cannot be understood, the error command ‘00H’ + ‘yyH’ is returned by the computer. When data sent by the projector cannot be understood (1) The computer sends the command code ‘3xH’ , ‘4xH’ or ‘4xH’ + ‘yyH’ +data to the projector. (2) When the command sent by the projector cannot be understood, the the error code ‘0xH’ +‘yyH’ +data is returned. When the data length is greater than indicated by the data length code, the projector will ignore the excess data code. Conversely, when the data length is shorter than indicated by the data length code, an error code will be returned to the projector. When a frame error occurs Repeats 10 times per second until there is some sort of response to the error code 70H + 70H. When the interval between bytes in one command is 500ms or greater When a command or data is not sent within 500ms after the command code ‘2xH’ , ‘3xH’ or ‘4xH’ is sent by the computer, the error command ‘70H’ +‘70H’ will be returned as soon as the 500ms elapses. After this, if there is no response within 1 sec., a frame error will occur. The response data in (3) above need not match the setting data in (1). For example, when the projector cannot set the setting data in (1), the projector may set the closest value. That value will be used as the response data in (3). Or else the projector will return the error code ‘0xH’ + ‘yyH’ +data.Caution • Operation cannot be guaranteed when the projector receives an undefined command or data. • Provide an interval of at least 40ms between the response code and any other code.Caution
