Connecting the USB cable
1. Connect the projector and computer with a suitable commercially available cable. Disconnect the mouse
cable from the projector.
2. Press the INPUT button of the projector or the RGB 1/2 button of the remote control and select the input
where the computer is to be connected.
3. Start the mouse function.
4. Refer to page 10 concerning the remote control of mouse operations.
5. Varying the force with which the DISK PAD button is pressed varies the speed of mouse operation.
USB jack
(B type)
• Before making connections, read the instruction manual of the equipment to be connected.
• Use the optional USB cable to connect.
• Effective with USB only when the mouse is used.
• Do not use with any device other than a personal computer.
• When using with Windows 95, it is necessary to set so that USB can be used with version
OSR 2.1 or higher. Depending on the kind or the virsion of the host controller, operation may
not be possible in some cases.
• With some notebook computers that use a built-in pointing device such as a track ball, 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. (Check laptop users guide)
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.

(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.

(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.
• 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.
