BenQ LW600ST WXGA Short Throw LED Simulation Projector Installation Guide

A: To control your BenQ projector via RS232,
follow the wire arrangement guide, choose the appropriate
connection method, set up the communication settings, and refer to
the command table for RS232 commands specific to your model.

Q: Can I change the Baud Rate for RS232
communication?

A: Yes, the Baud Rate is changeable in User OSD
settings. The default Baud Rate is 115200 bps, but you can select
from other options like 9600, 14400, 19200, 38400, or 57600
bps.

Q: How do I find the Wired LAN IP address of
the projector?

A: You can find the Wired LAN IP address of the
connected projector from the OSD menu. Make sure both the projector
and the computer are on the same network for proper
communication.

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 behaviors are identical with the control through a serial port.
