RS-232C Communication (continued)

Requesting projector status (Get command)

(1)Send the request code Header + Command data (‘02H’+‘00H’+ type (2 bytes)+ ‘00H’ +‘00H’) from the computer to the projector.

(2)The projector returns the response code ‘1DH’+ data (2 bytes) to the computer.

Changing the projector settings (Set command)

(1)Send the setting code Header + Command data (‘01H’+‘00H’+ type (2 bytes) + setting code (2 bytes)) 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 ‘06H’ to the computer.

Using the projector default settings (Reset Command)

(1)The computer sends the default setting code Header + Command data (‘06H’+ ‘00H’ + type (2 bytes) +‘00H’+‘00H’) to the projector.

(2)The projector changes the specified setting to the default value.

(3)The projector returns the response code ‘06H’ to the computer.

Increasing the projector setting value (Increment command)

(1)The computer sends the increment code Header + Command data (‘04H’+ ‘00H’+ type (2 bytes) +‘00H’+‘00H’) to the projector.

(2)The projector in creases the setting value on the above setting code.

(3)The projector returns the response code ‘06H’ to the computer.

Decreasing the projector setting value (Decrement command)

(1)The computer sends the decrement code Header + Command data (‘05H’+ ‘00H’+ type (2 bytes) +‘00H’ + ‘00H’) to the projector.

(2)The projector decreases the setting value on the above setting code.

(3)The projector returns the response code ‘06H’ to the computer.

When the projector cannot understand the received command

When the projector cannot understand the received command, the error code ‘15H’ is sent back to the computer.

Sometimes the projector cannot properly receive the command. In such a case, the command is not executed and the error code ‘15H’ is sent back to the computer. If this error code is returned, send the same command again.

When the projector cannot execute the received command.

When the projector cannot execute the received command, the error code ‘1CH’

+‘xxxxH’ is sent back to the computer. When the data length is greater than indicated by the data length code, the projector 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 computer.

NOTE • 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.

•The projector outputs test data when the power supply is switched ON, and when the lamp is lit. Ignore this data.

•Commands are not accepted during warm-up.

CP-X705, CP-X615 specifications

The Hitachi CP-X615 and CP-X705 are advanced projectors designed for educational and business environments, boasting a variety of impressive features and technologies that cater to the needs of diverse users. Both models share core characteristics that enhance their usability, performance, and image quality.

One of the standout features of the CP-X615 and CP-X705 is their exceptional brightness levels, with the CP-X615 delivering up to 3,200 ANSI lumens and the CP-X705 reaching 3,400 ANSI lumens. This high brightness ensures clear visibility even in well-lit rooms, making these projectors ideal for classrooms and conference halls where ambient light can be an issue. The native XGA (1024 x 768) resolution facilitates sharp and detailed images, making it suitable for presentations that involve text-heavy content or intricate visuals.

Both models also incorporate advanced image processing technologies. The "Active 3D" technology in the CP-X705 offers an immersive viewing experience for 3D content, catering to educational institutions that utilize three-dimensional visuals for enhanced learning. The CP-X615, while primarily focusing on 2D presentations, still delivers impressive performance with features like image correction and various display modes tailored for different content types.

Portability is another significant advantage of these projectors. Weighing approximately 3.5 kg, both the CP-X615 and CP-X705 are lightweight and easily transportable, allowing for quick setup and use in various locations. Additionally, the built-in speaker enhances the audio experience, reducing the need for external audio equipment in smaller settings.

Connectivity options are plentiful, with both models featuring multiple input terminals, including HDMI, VGA, and USB ports, facilitating seamless integration with a range of devices, from laptops to multimedia players. The projectors are also equipped with a network function, enabling remote control and monitoring, which is essential for IT administrators managing multiple units across different locations.

With their reliable performance, robust features, and user-friendly design, the Hitachi CP-X615 and CP-X705 projectors stand out as excellent choices for both educators and professionals seeking high-quality projection solutions. Their combination of brightness, resolution, and connectivity options ensures they can meet various presentation needs effectively.
