A1
Connecting the cable
Connect the RS-232C cable
as shown in the picture.
* The RS-232C protocol is used for communication between the PC and product. You can
turn the product 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
Communication Code : ASCII code
Use this method to connect several products to a single PC.
You can control several products at a time by connecting them to a single PC.

OK Acknowledgement
[Command2][ ][Set ID][ ][OK][Data][x]
* The Product 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

range : 1~99. by setting '0', server can control all products.
* In case of operating with more than 2 sets using set ID as '0' at the same
time, it should not be checked the ack message.
Because all sets will send the ack message, so it's impossible the check the
whole ack messages.
* [DATA]: To transmit command data.
Transmit 'FF' data to read status of command.
