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.
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.
