RS-232C Adjustment

This display has an RS-232C terminal. It is possible to use a PC to make various adjustments and settings.

1 About the RS-232C Adjustment

Adjustments using the RS-232C:

• 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. 257 to 261)).

Note

(1) Assign an ID before using the RS-232C adjustment. Include the panel ID in the RS-232C command.

For details, refer to section 5.5.2, “Interface” (pg. 263).

(2) Of the adjustment values and setting items set by RS-232C commands, there are some items that are

stored in memory and some that are not. For details, refer to section 5.5.5, “List of RS-232C Commands”

(pg. 267). Also, when storing values in “last” memory, the conditions described in section 5.1.5, “Last

Memory” (pg. 170), must be satisfied.

(3) <OSDS00>/<OSDS01> (OSD display disable/enable setting)

Regardless of the setting, the following items can be displayed.

• Menu display (menu mode, integrator mode)

• Warnings before Auto Power OFF or Power Management operation

• Warning of high temperature inside the panel

• Display announcing that the FUNCTIONAL LOCK is set and the FUNCTIONAL LOCK setting display

• Display call (including holding a button down)

(4) When using RS-232C commands, control the input signal as well as the power. If the power is ON when

there is no signal, the display continues to have a weak discharge. This activity can affect the life of the

display.

Note

The baud rate of this display should be set to match the baud rate of the PC.

Also, when the RS-232C cable is extended over a long distance, use a slower baud rate.

6) Protocol

From the PC to the display

(1) Sending one command at a time:

STX (02 hex)

ID (2 Byte) COMMAND (3 Byte or 6 Byte) ETX (03 hex)

(2) Sending numerical direct commands:

STX (02 hex)

ID (2 Byte) COMMAND (3 Byte) ARGUMENT (3 Byte) ETX (03 hex)

ID, COMMAND, ARGUMENT are transmitted as ASCII characters.

From the display to a PC

(1) Echo back (Normal response)

Command received and returned but the ID is not returned.

STX (02 hex)

COMMAND (3 Byte or 6 Byte) ETX (03 hex)

Received command is a numerical direct effect command and numerical data is returned:

STX (02 hex) COMMAND (3 Byte) ARGUMENT (3 Byte) ETX (03 hex)

(2) Error (Abnormal response)

Received command is a non-corresponding command, ‘ERR’ is returned:

STX (02 hex)

ERR (3 Byte)

ETX (03 hex)

Received command cannot be processed (when PON is received when the power is already ON, etc.), ‘XXX’ is

returned:

STX (02 hex)

XXX (3 Byte)

ETX (03 hex)

RS-232C Adjustment

3 Combination Connection

When controlling/adjusting panels, it is convenient to connect several displays to one PC.

By performing a combination connection and assigning IDs to the panels, it is possible to control and adjust several

displays at the same time or separately.

Connection method:

Connect the panels as shown in the figure below.

First Panel

Second Panel

Third Panel

OUT

RS-232C

COMBINATION

OUT

Combination cable

Note

Only the combination IN terminal or the RS-232C terminal can be used at the same time. Connecting them at the

same time could cause errors. Also, do not pair combination IN terminals or combination OUT terminals. Doing so

could cause communication to fail.

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, 5.5.4, “ID Assignment” (pg. 265).

Download from Www.Somanuals.com. All Manuals Search And Download.

RS-232C Adjustment

4 ID Assignment

The ID is assigned from the PC.

Commands: <IDC> (ID CLEAR)........ Clears the assigned ID

<IDS> (ID SET) ............. Assigns an ID

IDS is only effective when an ID is not assigned.

IDs are assigned starting from the panel closest to the PC.

Example: Case of 4 displays (assigning IDs with the PC for the first time)

First, connect an RS-232C and combination cables. (Refer to section 5.5.3, “Combination Connection” (pg.

264).)

Set #1

Set #2

Set #3

Set #4

OUT

ID = 01

ID = 02

ID = 03

ID = 04

RS-232C connection

Sent commands:

1 <01 IDS>

‘

2 <02 IDS>

‘

3 <03 IDS>

‘

4 <04 IDS>

By sending RS-232C commands in this order, it is possible to assign an ID for each panel.

When a panel has a PC-assigned ID, it can only receive commands containing the ID. Assign an ID before sending a

command.

Characters that can be used for an ID include, 0 - 9 and A - F (there is not distinction between upper case and lower case

letters).

An ∗ (asterisk) can be used as follows:

<∗∗IDC>: Clear the IDs assigned for all panels

<2∗IN1>: The input for which the first digit is 2 is set to INPUT1

Precautions when assigning IDs

Panels connected after a display’s ID has been cleared cannot be operated with RS-232C commands.

When the <∗∗IDC> command is sent, the IDs for all the sets from Set #1 to Set #4 are cleared. Only the first panel,

which is directly connected to the PC, can be controlled.

Send the command <01 IDS> to control the next panel. Continue setting IDs in this way for the remaining panels to

once again control the displays.

Note

When the IDs are set, when one or both of the IDs before a command is sent from the PC is an ∗, there is no echo.

When sending more commands, wait six 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.

RS-232C Adjustment

Under the connection conditions shown below, use a combination cable for up to 16 panels.

Conditions: 1 Length of RS-232C cable connecting PC to Plasma Display: 5 m

2 Combination cable length: 5 m each

3 Wire specifications for linking cable: Mini Din 6-pin straight (7 strand cable)

For one strand, suitable for AWG28:

Cross-section area = 0.08 mm²

≠

7 strands × π r²= 7 × 3.14 × 0.06²= 0.079 mm²≠ 0.08 mm²
