* The RS-232C protocol is used for communication between the PC and monitor. 
You can turn the monitor on/off, select an input source or adjust the OSD menu
from your PC.
Baud Rate : 9600bps (UART)
Data Length : 8bits
Parity Bit : NONE
Stop Bit : 1bit
Flow Control : NONE
Use a straight cable
Use this method to connect several monitors to a single PC.
You can control several monitors at a time by connecting them to a single PC.

Transmission
[Command1][Command2][ ][Set ID][ ][Data][Cr]
* [Command 1]: First command.
* [Command 2]: Second command.
* [Set ID]: You can adjust the set ID to choose desired monitor
ID number in Setup menu. Adjustment range is 
0~ 99. When selecting Set ID ‘0’, every connected
monitor set is controlled. Set ID is indicated as decimal
(0~99) on menu and as Hexa decimal (0x0~0x63)
on transmission/receiving protocol.
* [DATA]: To transmit command data.
Transmit 'FF' data to read status of command.
* [Cr]: Carriage Return
ASCII code ‘0x0D’
* [    ]: ASCII code Space (0x20)’
OK Acknowledgement
[Command2][ ][Set ID][ ][OK][Data][x]
* The Monitor transmits ACK (acknowledgement) based on
this format when receiving normal data. At this time, if the
data is data read mode, it indicates present status data. If
the data is data write mode, it returns the data of the PC
computer.
Error Acknowledgement
[Command2][ ][Set ID][ ][NG][Data][x]
* The Monitor transmits ACK (acknowledgement) based on
this format when receiving abnormal data from non-viable
functions or communication errors.
Data 1: Illegal Code
2: Not supported function
3: Wait more time
