Acknowledgement

[Command2][ ][Set ID][ ][OK/NG][Data][x]

* When the product receives data normally, it sends an acknowledgement (ACK) in the format above. If data is

in read mode, it indicates the data that shows the current status. If data is in read mode, it simply indicates the

data that is sent from the PC.

* If a command is sent with Set ID '00' (=0 x 00), the data is reflected to all monitor sets and they do send any

acknowledgement (ACK).

* If the data value 'FF' is sent in control mode via RS-232C, the current setting value of a function can be

checked (only for some functions).

* Some commands are not supported depending on the model.
