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.

Can I control multiple projectors using RS232?
Yes, you can control multiple projectors using RS232 by connecting each projector to a separate COM port on your computer.
What are the available baud rates for RS232 communication?
The available baud rates are 9600, 14400, 19200, 38400, 57600, and 115200 bps. The default baud rate is 115200 bps.
How do I find the Wired LAN IP address of the connected projector?
You can find the Wired LAN IP address from the OSD menu of the projector.
Can I control the projector via LAN if the computer and projector are not on the same network?
No, the computer and projector need to be on the same network for LAN control.
Is a crossover cable necessary for RS232 serial port connection?
Yes, a crossover cable is required for RS232 serial port connection.
