Transmission/Reception Protocol

Transmission

[Command1][Command2][ ][Set ID][ ][Data][Cr]

* [Command1]: identifies between the factory setting and the user setting modes.

* [Command2]: controls monitor sets.

* [Set ID]: Used for selecting a set you want to control. A unique Set ID can be assigned to each set

ranging from 1 to 1000(01H~3E8H) under Settings in the OSD menu.

Selecting '00H' for Set ID allows the simultaneous control of all connected monitors.

* [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 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 monitor sets and each monitor

set does 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 are not supported depending on the model.
