RS-232C Adjustment Mode
1.0 RS-232C Adjustment Mode
This display panel has an RS-232C terminal. It is possible to use a PC to make adjustments and settings.
1.1 About the RS-232C Adjustment Mode
1) Adjustments in the RS-232C adjustment mode:
• The adjustments are written to the same memory area as for the integrator mode. Refer to section 5.4.4,
“PICTURE, White Balance and SCREEN Position Adjustment Values Memory Area Tables" (pg. 211).
2) Display screen in the RS-232C adjustment mode:
––
1280X0214@60Hz
• The screen appears as shown to the right.
The set ID is display in the ‘– –’ area in the upper left corner
of the screen.

Notes
(1) Always assign an ID before using the RS-232C adjustment mode. Also, include the ID for the set
to be controlled or adjusted in the RS-232C command. For details, refer to section 5.5.2, “Interface"
(pg. 217).
(2) There are some RS-232C commands that can be used in the normal-operation mode.
For details refer to section, 5.5.5, “List of RS-232C Commands" (pg. 221).
(3) Some adjustment values and items set by RS-232C commands are stored in memory while other values
sand settings are not. For details, refer to section 5.5.5, “List of RS-232C Commands" (pg. 221).
Also, when storing final values in memory, the conditions described in section 5.1.5, “Last Memory"
(pg. 152), must be satisfied.
(4) <DIN>/<DIY> (OSD display disable/enable setting)
The following items can be displayed regardless of the setting:
• Menu display (menu mode, integrator mode)
• Warnings before Auto Power OFF or Power Management operation
• Warning of high temperature inside the set
• Display announcing that the FUNCTIONAL LOCK is set, and the FUNCTIONAL LOCK setting display
• Display call (including holding a button down)
(5) The RS-232C adjustment mode is automatically cancelled in the following cases:
• When the [STANDBY/ON] or [MENU] button is pressed
(6) Cancel the Integrator mode before entering the RS-232C adjustment mode.
(6) When controling the panel using RS-232C commands, control both the input signal and the power. If
the power is ON when there is no signal, the display continues to have a weak discharge. A discharge
could affect the life of the display.

1.3 ID Assignment
After connecting to a computer, the PC can assign an ID for each plasma display panel.
Commands: <IDC> (ID CLEAR) ........ Clears the assigned ID
<IDS> (ID SET) ............. Assigns an ID
IDS is only effective when an ID is not assigned.
Also, IDs are set starting from the set closest to the PC.
Example: Case of 4 displays (assigning IDs with the PC for the first time)
Connect each unit as shown below.
Refer to section 5.5.4, “Combination Connection" (pg. 219).

Sent commands:

3 <∗∗AJY>
4 <02 IDS>
‘
5 <∗∗AJY>
6 <03 IDS>
‘
7 <∗∗AJY>
8 <04 IDS>
By sending RS-232C commands in this order, it is possible to assign an ID for each unit.
Units for which an ID has been set can only receive commands with an ID attached. Attach an ID before sending a
command.
ID characters can include 0 - 9 and A - F (there is no distinction between upper and lower case letters).
.
An ∗ (asterisk) can be used as follows:
<∗∗IDC>: Clear the IDs assigned for all sets
<∗1AJY>: Only a set with the second digit as 1 enters the RS-232C adjustment mode
<2∗IN1>: Only input of a set with the first digit as 2 is set to INPUT1
Precautions when assigning IDs
Units that were connected after a set whose ID was cleared cannot be operated with RS-232C commands.
After assigning a setting as shown in the figure above and <∗∗AJY> = <∗∗IDC> is performed, the IDs for all the sets
from Set #1 to Set #4 are cleared. Only the one set (Set #1) that is directly connected to the PC can be controlled.
Furthermore, by performing <∗∗ AJY> = <01 IDS>, it again becomes possible to control the second set (Set #2). By
setting IDs in the same way for the other sets, it again becomes possible to control the sets connected in succession.
Note
When the IDs are set and one or both of the IDs before a command are sent from the PC as a ∗, there is no echo
back. When sending more commands, wait 6 seconds before sending the next command.
Example) When ∗∗OOO and ∗1OOO or 1∗OOO (OOO is the command) are sent from the PC, operation is performed
but there is no echo back.

1.4 Combination Connection
When performing control and adjustment, it is easiest to connect several panels to one PC.
By performing a combination connection and assigning IDs to the displays, it is possible to control and adjust several
panels at the same time or separately.
Connection method:
Connect the panels as shown below. Control and adjust the units with the PC.

Note
Only the combination IN terminal or RS-232C terminal can be used at the same time on one panel. Connecting them
at the same time could cause errors or cause other problems so do not connect them at the same time. Also,
do not connect pairs of combination IN terminals or combination OUT terminals. Doing so could cause errors or
other problems.
It is possible to use a general-purpose mini DIN 6-pin (straight) cable for the combination cable.

Note
To output RS-232C signals from the combination OUT terminal, an ID must be assigned.
For details, refer to section, 5.5.3, “ID Assignment" (pg. 218).
