BenQ TK700STi Projector RS232 Command Control Installation Guide

Introduction

This document describes how to control your BenQ projector via RS232 from a computer. Follow the procedures to complete the connection and settings first, and refer to the command table for RS232 commands. Available functions and commands vary by model. Check the specifications and user manual of the purchased projector for product functions.

Wire Arrangement

RS232 Pin Assignment

Diagram shows a D-Sub 9-pin connector with pins numbered 1 through 9. A hexagonal shape encloses pins 1-5 and another encloses pins 6-9, with a central line connecting them.

Connections and Communication Settings

Choose one of the connections and set up properly before RS232 control.

RS232 serial port with a crossover cable

Diagram shows a PC or laptop connected to a projector via a D-Sub 9 pin (male) on the projector and a D-Sub 9 pin (female) on the cable, using a crossover communication cable. The cable wiring is illustrated showing connections between pins 2-3, 3-2, and 5-5 (Ground).

Settings

On-screen images in this document are for reference only. The screens may vary depending on your Operating System, I/O ports used for connection, and the specifications of the connected projector.

1. Determine the COM Port name used for the RS232 communications in Device Manager. The Device Manager window is shown, listing various hardware categories. Under 'Ports (COM & LPT)', a 'Prolific USB-to-Serial Bridge (COM6)' is highlighted.
2. Choose 'Serial' and the corresponding COM port (e.g., COM6) as the communication port.
3. Finish Serial port setup. A Tera Term 'Serial port setup' window is shown, allowing configuration of Baud rate, Data bits, Parity, Stop bits, and Flow control.

Serial Port Settings Summary

Note: Check the baud rate of the connected projector from its OSD menu.

RS232 via LAN

Diagram shows a PC or laptop connected to a projector via a LAN cable. The projector has an RJ45 port.

Settings

1. Find the Wired LAN IP address of the connected projector from the OSD menu and ensure the projector and the computer are on the same network.
2. Input 8000 in the TCP port # field in the connection software (e.g., Tera Term). A Tera Term 'New connection' window is shown, with TCP/IP selected, and fields for Host and TCP port#.

RS232 via HDBaseT

Diagram shows a PC or laptop connected to an HDBaseT compatible device, which is then connected to a projector via RJ45 ports using a LAN cable. The HDBaseT device also has a D-Sub 9 pin connection.

Settings

1. Determine the COM Port name used for the RS232 communications in Device Manager.
2. Choose 'Serial' and the corresponding COM port (e.g., COM6) as the communication port.
3. Finish Serial port setup. (Similar to the RS232 serial port setup described above).

Command Table

This section provides a comprehensive list of RS232 commands for controlling the BenQ TK700STi projector. Commands are categorized by function and include details on operation type (Write/Read), the specific command syntax (ASCII), and whether the command is supported.

Command Categories:

• Power: Commands for controlling power status (On/Off, Status).
• Source Selection: Commands to select various input sources such as HDMI, DVI, Component, Network, USB Display, HDbaseT, DisplayPort, etc.
• Audio Control: Commands for managing volume (master, mic), mute status, and audio source selection.
• Picture Mode: Commands to select predefined picture modes like Dynamic, Game, Cinema, Vivid, User modes, etc., and adjust settings like Brightness, Contrast, Sharpness, Color Temperature, and Aspect Ratio.
• Picture Setting: Commands for fine-tuning picture parameters including Keystone correction, Overscan, Color Calibration (Red, Green, Blue Gain/Offset), Hue, Saturation, Gain, Color Gamut, and Dynamic Iris.
• Operation Settings: Commands for controlling projector operations such as Projector Position, Quick Cooling, Auto Search, Menu Position, Direct Power, and Standby Settings.
• Baud Rate: Commands to set or query the communication baud rate.
• Lamp Control: Commands related to lamp mode (Normal, Eco, SmartEco), Dimming, and custom light levels.
• Miscellaneous: Commands for system firmware versions, Mac address, High Altitude mode, Lens memory management, and basic menu navigation (Up, Down, Left, Right, Enter, Back).

Note: Available features and commands may differ based on the projector's specifications. Commands are generally effective when the standby power is 0.5W or a supported baud rate is set. Case (uppercase/lowercase) is accepted for commands.
