BenQ LK954ST Projector Command Control Installation Guide

The 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.

Connections and communication settings

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

RS232 serial port with a crossover cable

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.

Determine the COM Port name used for the RS232 communications in Device Manager.
Choose Serial and the corresponding COM port as the communication port. In this given example, COM6 is selected.

Finish the Serial port setup.

Baud rate	115200 bps (default) Changeable settings in User OSD (9600/14400/19200/38400/57600/115200)
Data length	8 bit
Parity check	None
Stop bit	1 bit
Flow control	None

RS232 via LAN

Settings

Find the Wired LAN IP address of the connected projector from the OSD menu and make sure the projector and the computer are on the same network.

Input 8000 in the TCP port # field.

RS232 via HDBaseT

Settings

Determine the COM Port name used for the RS232 communications in Device Manager
Choose Serial an d the corresponding COM port as the communication port. In this given example, COM6 is selected.
Finish the Serial port setup.

Baud rate	115200 bps (default) Changeable settings in User OSD (9600/14400/19200/38400/57600/115200)

Stop bit	1 bit
Flow control	None

Command table

Available features differ by projector specification, input sources, settings, etc..
Commands are working if the standby power is 0.5W or a supported baud rate of the projector is set.
Uppercase, lowercase, and a mixture of both types of characters are accepted for a command.
If a command format is illegal, it will echo Illegal format.
If a command with the correct format is not valid for the projector model, it will echo Unsupported item.
If a command with the correct format cannot be executed under certain conditions, it will echo Block item.
If RS232 control is performed via LAN, a command works whether it starts and ends with <CR>. All the commands and behaviors are identical to the control through a serial port.
