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 (01H to FFH) or 1 to 1000 (00 01H to 03e8H) under OPTION in the OSD menu.
Selecting '00H' or '000H' for set ID allows the simultaneous control of all connected moni-
tors. (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), the data is reflected to all monitors and they do not send an
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.
