Introduction
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 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.
1. Determine the COM Port name used for the RS232 communications in Device Manager.
4
2. Choose Serial and the corresponding COM port as the communication port. In this given example, COM6 is selected.
3. Finish Serial port setup.

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 within 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 and the corresponding COM port as the communication port. In this given example, COM6 is selected.

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 correct format is not valid for the projector model, it will echo Unsupported item.
- If a command with correct format cannot be executed under certain condition, 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 behaviours are identical with the control through a serial port.
