Command Control via the Network (continued)

2. Response code / Error code ("h" shows hexadecimal)

The connection ID is attached for the TCP#23's response / error codes are used. The connection ID is same as the sending command format.

(1) ACK reply : 06h + ××h

(××h : connection ID)

(2)NAK reoly : 15h + ××h

(3)Error reply : 1Ch + 0000h + ××h

(4)Data reply : 1Dh + xxxxh + ××h

(5)Authentication error reply : 1Fh + 0400h + ××h

(6)Projector busy reply: 1Fh + ××××h + ××h

When the projector is too busy to receives the command ,the projector returens the error code.

In such a case, check the sending code and send the same command again.

Automatic Connection Break

The TCP connection will be automatically disconnected after there is no communication for 30 seconds after being established.

Authentication

The projector does not accept commands without authentication success when authentication is enabled. The projector uses a challenge response type authentication with an MD5 (Message Digest 5) algorithm. When the projector is using a LAN, a random 8 bytes will be returned if authentication is enabled. Bind this received 8 bytes and the authentication password and digest this data with the MD5 algorithm and add this in front of the commands to send.

Following is a sample if the authentication password is set to “password” and the random 8 bytes are “a572f60c”.

1)Select the projector.

2)Receive the random 8 bytes “a572f60c” from the projector.

3)Bind the random 8 bytes “a572f60c” and the authentication password “password” and it becomes “a572f60cpassword”.

4)Digest this bind “a572f60cpassword” with MD5 algorithm. It will be “e3d97429adffa11bce1f7275813d4bde”.

5)Add this “e3d97429adffa11bce1f7275813d4bde” in front of the commands and send the data.

Send “e3d97429adffa11bce1f7275813d4bde”+command.

6)When the sending data is correct, the command will be performed and the reply data will be returned. Otherwise, an authentication error will be returned.

NOTE • As for the transmission of the second or subsequent commands, the authentication data can be omitted when the same connection.

CP-X2514WN, CP-WX3014WN, CP-X3014WN, CP-X4014WN specifications

The Hitachi CP-X3014WN, CP-X4014WN, CP-WX3014WN, and CP-X2514WN projectors are designed to meet the diverse needs of educational institutions, corporate environments, and various presentation settings. Each model blends innovative technology with user-friendly features, ensuring high-quality visuals and seamless performance.

The CP-X3014WN and CP-X4014WN are notable for their bright image output, delivering brightness levels of up to 3,500 lumens, making them suitable for use in well-lit environments. Both projectors support XGA resolution, providing clarity for detailed presentations and sharp images. The CP-X3014WN is specifically tailored for standard projection needs, while the CP-X4014WN enhances user experience with additional connectivity options and advanced features, such as a wireless presentation capability, allowing users to connect without the hassle of cables.

On the other hand, the CP-WX3014WN excels with WXGA resolution, which is ideal for widescreen content and offers greater pixel density. This model maintains similar brightness at 3,500 lumens and is perfect for HD content and multimedia presentations. Enhanced features include a wide range of input options, including HDMI and USB, making it compatible with various devices.

The CP-X2514WN, while having a slightly lower brightness level at 3,000 lumens, still provides high-quality images suitable for smaller classrooms and meeting rooms. With XGA resolution, this model is ideal for basic data presentations and casual screenings. It focuses on economy without compromising on performance, making it a great choice for budget-conscious institutions.

All models incorporate Hitachi's advanced technologies, such as 3LCD technology, which ensures vibrant color reproduction and consistent brightness without the rainbow effect commonly associated with other projection technologies. Additionally, these projectors come with features such as automatic vertical keystone correction, which simplifies setup by instantly correcting image distortion.

Other essential characteristics include long-lasting lamp life, ranging from 5,500 to 10,000 hours in eco mode, and a low power consumption rating, both of which contribute to lower operational costs. With their robust design and comprehensive feature set, the Hitachi CP series projectors are well-suited to meet the dynamic needs of modern presentation environments, ensuring a reliable and effective projection solution.
