It outlines the necessary steps for establishing connections and configuring communication settings, followed by a comprehensive table of RS232 commands. The guide is designed to assist users in integrating their BenQ projectors into a controlled environment, allowing for remote operation and management from a computer.

Function Description

The primary function of this guide is to enable users to control their BenQ projectors remotely using RS232 commands. This capability allows for a wide range of operational controls, from basic power management to intricate picture and audio adjustments, as well as system settings. The RS232 interface provides a robust and reliable method for integrating the projector into a larger control system, such as a home automation setup or a professional AV installation.

The projector can be controlled through various connection methods:

RS232 Serial Port with a Crossover Cable: This is a direct serial connection between a computer (PC or laptop) and the projector using a D-Sub 9 pin crossover cable. This method is ideal for local control where the computer is in close proximity to the projector.
RS232 via LAN: For network-based control, the projector can be connected to a LAN via an RJ45 port. This allows for remote control over a network, making it suitable for installations where the projector is located away from the control computer.
RS232 via HDBaseT: In setups utilizing HDBaseT compatible devices, the RS232 control signals can be transmitted alongside video and audio over a single LAN cable. This simplifies cabling in complex installations and extends the reach of RS232 control.

The command set covers a broad spectrum of projector functions, including:

Power Control: Commands to turn the projector on and off, and to check its power status.
Source Selection: Ability to switch between various input sources such as COMPUTER/YPbPr, DVI-D, HDMI, Composite, S-Video, Network, USB Display, USB Reader, HDBaseT, DisplayPort, 3G-SDI, and Smart System.
Audio Control: Commands for adjusting volume, muting/unmuting audio, and selecting audio sources (e.g., Audio-Computer1, Audio-Video/S-Video, Audio-Component, Audio-HDMI).
Picture Mode Selection: Access to various predefined picture modes like Dynamic, Presentation, sRGB, Bright, Living Room, Game, Cinema (Rec.709), Standard/Vivid, Football, Football Bright, DICOM, THX, Silence mode, DCI-P3 mode (D. Cinema), Vivid, Infographic, User1, User2, User3, ISF Day, ISF Night, 3D, Sport, HDR10, HLG, and Spreadsheet.

Dynamic Iris control (ON/OFF) and Color Calibration Save/Pattern Display are also available.

Usage Features

The guide emphasizes a structured approach to setting up RS232 control:

Connection: Users must first choose the appropriate connection method (serial port, LAN, or HDBaseT) and ensure the physical connection is correctly established. This includes using a crossover cable for direct serial connections and ensuring network connectivity for LAN/HDBaseT.
Communication Settings: After physical connection, the guide details how to configure communication parameters on the computer. For serial connections, this involves identifying the COM Port in Device Manager and setting up the serial port with specific baud rate, data length, parity check, stop bit, and flow control. The default baud rate is highlighted as a critical setting. For LAN connections, users need to find the projector's IP address from its OSD menu and input the correct TCP port number (8000).
Command Execution: Once the connection and settings are verified, users can send RS232 commands to the projector. The command table provides the exact ASCII strings for each function, including the required <CR> (carriage return) at the end of each command. Commands are typically in the format <CR>*command#<CR> or <CR>*command=value#<CR>.
Read Commands: Many commands have a corresponding "Read" operation, allowing users to query the current status or value of a particular setting (e.g., <CR>*power=?#<CR> to check power status). This is crucial for feedback and verification in automated systems.
Value-Based Commands: Several commands allow for setting specific values (e.g., brightness, contrast, color temperature). These commands typically use "value" as a placeholder, which should be replaced with the desired numerical or descriptive setting.
Increment/Decrement Commands: For settings like brightness, contrast, and color, there are also commands to increment or decrement the value (e.g., +#<CR> or -#<CR>), providing granular control without needing to know the exact current value.
Model-Specific Functions: The guide explicitly states that available functions and commands may vary by model. Users are advised to consult the specifications and user manual of their specific projector for accurate product functions. This ensures that users do not attempt to use commands that are not supported by their device.
On-Screen Image Reference: The document notes that on-screen images are for reference only and may vary based on the operating system, I/O ports, and connected projector specifications. This manages user expectations regarding visual consistency.

Maintenance Features

While the guide primarily focuses on control, some commands can be considered maintenance-related:

Reset Picture Settings: Commands like rstcurpicsetting#<CR> (reset current picture settings) and rstallpicsetting#<CR> (reset all picture settings) allow users to revert picture adjustments to default values, which can be useful for troubleshooting or preparing the projector for a new setup.
Lamp Hour Monitoring: The Itim=?#<CR> command allows users to read the lamp hours, which is a critical maintenance indicator for projectors. This helps in planning lamp replacements and ensuring optimal performance.
Quick Cooling: The qcool=on<CR> and qcool=off<CR> commands, along with qcool=?<CR> for status, relate to the projector's cooling system. Proper cooling is essential for the longevity and stable operation of the projector lamp and internal components.
High Altitude Mode: Commands for Highaltitude=on#<CR> and Highaltitude=off#<CR> are important for projectors operating in high-altitude environments, where different cooling profiles are required to prevent overheating.
