Notes:
Use the RS-232C straight cable to connect the computer
to the Plasma Display.
The computer shown is for example purposes only.
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.

The SERIAL terminal is used when the Plasma Display is controlled by a computer.
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.
Start
(02h) 3-character
command (3 bytes)
Colon Parameter(s)
(1 - 5 bytes) End
(03h)
STX C1 C2 C3 P1 P2 P3 P4 : P5 ETX
Notes:
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.
If an incorrect command is sent by mistake, this unit will
send an “ER401” command back to the computer.
SL1A, SL1B, SL2A and SL2B of Command IMS are
available only when a dual input terminal board is attached. •
