Hitachi CP-S833W, CP-S833E Procedure of getting the Projector status, Example of command error

Page 26

Connection to the control signal terminal (continued)

The procedure of getting the Projector status

(1)Computer sends the command '20H'+'yyH' to Projector. (2)Projector reply the command '1xH'+'yyH'+data bytes.

The procedure of setting the Projector status

(1)Computer sends the command '3xH'+'yyH'+data bytes. (2)Projector changes it’s status.

(3)Projector reply the command '1xH'+'yyH'+data bytes which indicate status.

Caution

∙ (3) data bytes is not always same as (1) data bytes. If projector cannot realize the status of (1)

data bytes, projector set the proper status and reply this new setting data bytes or projector

 

 

reply the error reply '0xH'+'yyH'+data bytes same as (1).

∙When only power control (POWER COMMAND) is performed, it takes about 2~80 seconds between sending set code and receiving answering code.

The procedure of default setting the Projector status

(1)Computer sends the command '40H'+'yyH' (2)Projector changes it's status to default setting.

(3)Projector reply the command '1xH'+'yyH'+data bytes which indicate default.

Caution If projector replys '4Dh', (before command code, etc.) computer ignores '4Dh'

The example of command error

When projector cannot accept command from PC, error code '00H'+'yyH' is sent back.

(in a case when command code '2xH', '3xH' or '4xH'+'yyH'+data is sent from PC to projector)

The example of data error

When projector cannot accept command from PC, error code with data '00H'+'yyH'+data is sent back as it is. (in a case when command code '2xH', '3xH' or '4xH'+'yyH'+data is sent from PC to projector)

When data is longer than required data code length, projector ignores excess data code.

When data is shorter than required data code length, projector sends back error code shown above.

The example of framing error

After setting to 1200bps 7N1, projector sends error code '70H'+'70H' up to 10 times at intervals of 1 second until any answer is received. When projector receives framing error code ('70H'+'70H'), '12H'+'03H'+'03H'+'10H' is sent with 1200 bps 7N1.

The interval of command bytes and data bytes

After command code '2xH', '3xH' or '4xH' is sent from PC, if command or data is not sent within 500ms, projector sends back error command '70H'+70H'. If no answer is sent within 1 second from that time, framing error is assumed.

Caution

∙ The interval of command bytes and data bytes must be over 1mS and under 500mS. If it is

under 1mS, it may be treat as framing error.

 

∙After projector has sent back answer code, when next command is to be sent from PC, allow for an interval of 40ms or more between answer code and other code.

CP-S833W, CP-S833E specifications

The Hitachi CP-S833E and CP-S833W projectors stand out in the market for their balance of quality, performance, and versatility, making them ideal for both business presentations and educational environments. These projectors are designed to provide vibrant visuals, ensuring that audiences remain engaged and informed.

One of the main features of the CP-S833E and CP-S833W is their high brightness level, rated at around 3,000 ANSI lumens. This impressive brightness ensures that images are clear and visible even in well-lit rooms. Coupled with a high contrast ratio, these projectors deliver sharp images with deep blacks and vibrant colors, enhancing the overall viewing experience.

Both models utilize 3LCD technology, which helps in producing accurate color reproduction while minimizing the risks of color breakdown often associated with other projection technologies. The 3LCD system effectively uses three chips to project red, green, and blue light, resulting in richer and more natural images.

The Hitachi CP-S833E and CP-S833W are equipped with a native XGA resolution of 1024 x 768 pixels. This resolution strikes a good balance between image quality and performance, making it suitable for various content types, whether it be text-heavy slides, videos, or images. Furthermore, the projectors support various input options, including HDMI, VGA, and composite video, allowing for easy connectivity with a wide range of devices.

Additionally, these projectors come with features such as keystone correction and a built-in speaker, which enhance flexibility and functionality. Keystone correction allows users to adjust the projected image, ensuring it maintains a proper rectangular shape even when the projector is not perfectly aligned with the screen. The built-in speaker makes it convenient for users to present without needing additional audio equipment.

In terms of energy efficiency, both models are designed to consume less power. They feature a long lamp life, extending up to 5,000 hours in eco mode, which reduces replacement costs and contributes to lower overall operating expenses.
