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.
