RS232 Port Specifications
PC control of the TV
• 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.
Communication conditions
Set the RS-232C communication settings on the PC to
match the TV's communication conditions.
The TV's communication settings are as follows:
•
Communication procedure
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.
Parameter
Input the parameter values, aligning left, and fill 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.
