(1)   
ACK reply: 06h 
When the projector receives the Set, Increment, Decrement or Execute 
command correctly, the projector changes the setting data for the specified 
item by [Type], and it returns the code.
(2)   NAK reply: 15h 
When the projector cannot understand the received command, the projector 
returns the error code. 
In such a case, check the sending code and send the same command again.

When the projector connects network, the projector can be controlled with RS-
232C commands from the computer with web browser. 
For details of RS-232C commands, refer to RS-232C Communication / Network 
command table 
(&19).
