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.
