PC Input Terminals connection
Notes:
•  With regard to the typical PC input signals that are described in the ap\
plicable input signals list, adjustment values such as for the standard picture positions and sizes have already been stored\
 in this unit. You can add up to eight PC input 
signal types that are not included in the list.
•  Computer signals which can be input are those with a horizontal scanning\
 frequency of 15 to 110 kHz and vertical scanning  frequency of 48 to 120 Hz. (However, the image will not be displayed properly if the signals exceed 1,200 l\
ines.)
•  The display resolution is a maximum of 768 × 768 dots when the aspect\
 mode is set to “4:3”, and 1,024 × 768 dots   when the aspect mode is set to “FULL”. If the display resolution e\
xceeds these maximums, it may not be possible to 
show fi  ne detail with suffi  cient clarity.
•  The PC input terminals are DDC2B-compatible. If the computer being conne\
cted is not DDC2B-compatible, you will need  to make setting changes to the computer at the time of connection.
•  Some PC models cannot be connected to the set.
•  There is no need to use an adapter for computers with DOS/V compatible M\
ini D-sub 15P terminal.
•  The computer shown in the illustration is for example purposes only.
•  Additional equipment and cables shown are not supplied with this set.
• Do not set the horizontal and vertical scanning frequencies for PC signa\
ls which are above or below the speci fi ed 
frequency range.
•  Component Input is possible with the pin 1, 2, 3 of the Mini D-sub 15P Connector.
•  Change the “COMPONENT/RGB-IN SELECT” setting in the “SET UP” menu to “COMPONENT” 
  (when COMPONENT signal connection) or “RGB” (when RGB signal connection).

SERIAL Terminals connection
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 
specifi  cation, 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 satis fi es  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.

command (3 bytes)Colon Parameter(s)

Notes:
•  If multiple commands are transmitted, be sure to wait for 
the response for the fi  rst 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.
•  S1A and S1B of Command IMS are available only when a  dual input terminal board is attached.
