Transmission / Receiving Protocol

Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr]
* [Command1]: First command to control the set.
* [Command2]: Second command to control the set.
* [Set ID]: Used for selecting a set you want to control. A Set ID can be assigned to each set from 1 to 255 (from
01H to FFH), or from 1 to 1,000 (from 001H to 3e8H) in certain models, under OPTION in the OSD
menu. Selecting '00H' or '000H' for Set ID allows the simultaneous control of all connected monitors. (It
may not be supported depending on the model.)
* [Data]: Transmits command data.
Data count may increase depending on the command.
* [Cr]: Carriage Return. ASCII code '0x0D'.
* [ ]: White Space. Corresponds to '0x20' in ASCII code.
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' (=0x00) or '000 (=0x000)', 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.
