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.
