COMPUTER
The SERIAL terminal is used when the High Definition Plasma Display is controlled by a computer.
The SERIAL terminal conforms to the RS-232C interface specification, so that the High Definition Plasma Display can
be controlled by a computer which is connected to this terminal.
The computer will require software which allows the sending and receiving of control data which satisfies the conditions
given below. Use a computer application such as a programming language to software. Refer to the documentation for
the computer application for details.

Basic format for control data
The transmission of control data from the computer starts
with a STX signal, followed by the command, the
parameters, and lastly an ETX signal in that order. If there
are no parameters, then the parameter signal does not
need to be sent.
Note:
If multiple commands are transmitted, be sure to wait for
the response for the first command to come from this unit
before sending the next command.
