Notes:

(1)Use the RS-232C cable to connect the computer to the Plasma Display.

(2)The computer shown is for example purposes only.

(3)Additional equipment and cables shown are not supplied with this set.

The SERIAL terminal conforms to the RS-232C interface specification, so that the 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 programming language 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.

Notes:

(1)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.

(2)If an incorrect command is sent by mistake, this unit will send an “ER401” command back to the computer.
