Transmission / Receiving Protocol
Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr]
* [Command1] Identifies the factory setting and the user setting modes.
* [Command2] Controls monitors.
* [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. Corresponds to '0x0D' in ASCII code.
* [ ] White Space. Corresponds to '0x20' in ASCII code.
Acknowledgement
[Command2][ ][Set ID][ ][OK/NG][Data][x]
* The Product transmits an ACK (acknowledgement) based on this format when receiving normal data. At this
time, if the data is FF, it indicates the present status data. If the data is in data write mode, it returns the data
of the PC computer.
* 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 may not be supported on some models.
