RS-232C Specifications and Commands

Computer control

A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type, commercially available) to the projector. (See page 27 of the projector’s operation manual for connection.)

Communication conditions

Set the serial port settings of the computer to match that of the table.

Signal format: Conforms to RS-232C standard.	Parity bit: None
Baud rate*: 9,600 bps / 38,400 bps / 115,200 bps	Stop bit: 1 bit
Data length: 8 bits	Flow control: None

*Set the projector’s baud rate to the same rate as used by the computer.

Basic format

Commands from the computer are sent in the following order: command, parameter, and return code. After the projector processes the command from the computer, it sends a response code to the computer.

Command format

C1 C2 C3 C4 P1 P2 P3 P4

Return code (0DH)

Command 4-digit

Parameter 4-digit

Response code format Normal response

O K

Return code (0DH)

Problem response (communication error or incorrect command)

E	R	R		Return code (0DH)

Info

•When controlling the projector using RS-232C commands from a computer, wait for at least 40 seconds after the power has been turned on, and then transmit the commands.

•After sending an input selection or picture adjustment command and then receiving an “OK” response code, the projector may take some time to process the command. If a second command is sent while the projector is still processing the first command, you may receive an “ERR” response code. If this happens, try resending the second command.

•When more than one code is being sent, send each command only after the response code for the previ- ous command from the projector is verified.

•“POWR????” “TABN _ _ _ 1” “TLPS _ _ _ 1” “TPOW _ _ _ 1” “TLPN _ _ _ 1” “TLTT _ _ _ 1” “TLTL _ _ _ 1” “TNAM _ _ _ 1” “MNRD _ _ _ 1” “PJN0 _ _ _ 1”

−When the projector receives the special commands shown above:

*The on-screen display will not disappear.

*The “Auto Power Off” timer will not be reset.

−The special commands are available for applications that require continuous polling.

Note

•If an underbar (_) appears in the parameter column, enter a space.

•If an asterisk (*) appears in the parameter column, enter a value in the range indicated in brackets under Control Contents.

*1 Serial No. Check command is used to read out the 12 digits of serial No..

*2 For setting the projector name, send the commands in the order of PJN1, PJN2 and PJN3. *3 Parameters of CLR Temp settings are as follows.

CLR Temp	Parameter	CLR Temp	Parameter
5500K	_0 5 5	8500K	_0 8 5
6500K	_0 6 5	9300K	_0 9 3
7500K	_0 7 5	10500K	_1 0 5

*4 The adjustable range of “V-Pos” (V-Position) may vary depending on the screen resolution of the computer.

XG-C330X, XG-C335X, XG-C430X specifications

The Sharp XG-C430X and XG-C330X are advanced projectors designed to deliver high-quality presentations and visuals, making them ideal for educational, corporate, and professional environments. Both models leverage cutting-edge technologies to provide an efficient and impactful viewing experience.

One of the standout features of the XG-C430X and XG-C330X is their impressive brightness levels, making them suitable for diverse lighting conditions. The XG-C430X boasts a brightness of 4300 lumens, while the XG-C330X delivers 3300 lumens, ensuring that images remain vibrant and clear even in well-lit rooms. This high brightness, combined with a native resolution of XGA (1024 x 768), allows both projectors to produce sharp and detailed images for presentations, graphics, and video content.

The projectors are built with DLP (Digital Light Processing) technology, which enhances color accuracy and contrast, resulting in high-quality visuals with rich colors and deep blacks. This technology also minimizes the rainbow effect often found in traditional projection systems, providing a smoother viewing experience. Additionally, they use a reliable lamp with a long lifespan, requiring less frequent replacements and ensuring cost-effectiveness over time.

Another key characteristic of the XG-C430X and XG-C330X is their versatility in connectivity options. They come equipped with multiple input ports, including HDMI, VGA, and composite video, allowing users to connect various devices such as laptops, DVD players, and streaming devices seamlessly. This capability enhances usability, making them suitable for a wide range of applications, from classroom learning to business presentations.

The lightweight and portable design of both projectors makes them easy to transport between locations, catering to the needs of users who require mobility. Their compact size does not compromise performance, making them an excellent choice for organizations that need reliable and high-performing projection solutions.

Additionally, the XG-C430X and XG-C330X feature automatic keystone correction, simplifying setup and ensuring that the projected image is perfectly aligned. This functionality helps to eliminate distortions that can occur when the projector is not perfectly centered, enhancing the overall viewing experience.

In summary, the Sharp XG-C430X and XG-C330X projectors combine high brightness, superior image quality, versatile connectivity, and user-friendly features, making them ideal for a range of professional and educational settings. Their advanced DLP technology, portability, and cost-effective operation further solidify their status as top choices for high-performance projection needs.
