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 the Illegal format.
• If a command with the correct format is not valid for the projector model, it will echo the Unsupported item.
