•  Attach an RS-232C cable cross-type (commercially 

available) to the supplied Din/D-Sub RS-232C for the 

connections.

This operation system should be used by a person who is 

accustomed to using computers.

Set the RS-232C communication settings on the PC to 

match the TV's communication conditions.

The TV's communication settings are as follows:

•

Send the control commands from the PC via the RS-

232C connector.

The TV operates according to the received command 

and sends a response message to the PC.

Do not send multiple commands at the same time. 

Wait until the PC receives the OK response before 

sending the next command.

Input the parameter values, aligning left, and fi ll with 

blank(s) for the remainder. (Be sure that 4 values are 

input for the parameter.)

When the input parameter is not within an adjustable 

range, “ERR” returns. (Refer to “Response code format”.)

Any numerical value can replace the “x” on the table.
