To initialize the desired area, firstly select the desired item from the EEPROM RESET menu. Change the selected item from “CANCEL” to “OK”. Then press “ENTER”.

a) Whole Area

It initializes whole area of EEP ROM. This command is identical to executing the all items of “Common”, “White Balance”, “Prog. Gamma”, “Tuner”, “Prog. Preset”, “Last Memory”, “User Memory” and “Factory”. Execute this command only when the memory (IC1007) on the B board is replaced.

b) Common

It initializes “Common (1)”, “Common (2)” and “Common (3)” of the “COMMON DATA AREA” shown in Table 1. It initializes the data unique to the particular machine and the shared data (various setup values of the user menu”. Because it initializes the serial number and accumulative operation hours, do not execute this command.

c) White Balance

It initializes “Color Temp (1)” and “ Color Temp (2)” of the “COMMON DATA AREA” shown in Table 1. It initializes the color temperature “High”, “Mid” and “Low”, and all data of user setup 1 to 3 to all 0. It also initializes the user name to “User1”, “User2” and “User3”.

d) Prog. Gamma

This command is not used in this machine.

e) Tuner

This command is not used in this machine.

f) Prog. Preset

It initializes the “PRESET DATA AREA” shown in Table 1. It resets the backup preset area.

g) Last Memory

It initializes “LAST MEMORY AREA” shown in Table 1. It initializes the last memory data that user has adjusted for each signal.

h) User Memory

It initializes “USER MEMORY AREA” shown in Table 1. It resets all of the 20 types of the adjustment data that are saved in the “User Memory” function of the user menu.

i) Factory

It resets the EEP ROM to the factory default status. All of the EEP ROM areas except the following are initialized by this command.

Items that are not initialized by the “FACTORY” RESET function.

Perform this setup only when the logic board located in the bottom center on the rear of the PDP panel, is replaced. Take reading of the Vs voltage value and the Va voltage value that is written on the label on the rear of the PDP panel, and enter the Vs and Va values in the equations (1) and (3).

These submenu items are used in factory for operation checks. Do not operate this function.

Editing procedure

An independent memory area (editing RAM) is assigned for data editing inside the system controller as shown. First, copy the source data for editing to the editing RAM. Then modify the data on the editing RAM and save the editing contents to the specified preset area of EEP ROM. In addition to the default preset data that has been set already when shipped from the factory, you can edit the various data from the already saved data in EEP ROM or the signal data that is being input at this moment. (An example shows the case the data stored in the EEP ROM preset area No.2 is used for editing and the edited data is stored in the area No.11.)

Original Data Select Current Data Select (1) The signal data that is being Table input at this moment, is used

as the original data for editing.

(2) The data stored in the preset

area is used for editing.

(1) Current Data Select

When you select the signal data that is being input at this moment for editing, move the cursor to this item and press ENTER. The selected data is copied to the editing RAM. This mode is prepared for the case that the signal specification is unknown, and you can make editing by confirming the specification on screen. Select the respective adjustment items and change the data as desired using the ↑/↓ key or the ←/→ key. The changed data are reflected on screen. (If you press the ENTER key again, the screen returns to the previous menu.) Among the adjustment items, the three types of adjustment [H Freq], [V Freq] and [Sync Pol] cannot be modified.

(2) Table

When you select the data stored in the preset area, move the cursor to this item and press ENTER. Select the desired data using the ↑/↓ key. The selected data is copied to the editing RAM. This mode is prepared for the case that the signal specification is already known. You can make adjustment and edit data of all items but the modified data are not reflected to the actual picture images.

(1) H Freq

It sets the horizontal frequency.

When “Current Data Select” is selected in the Original Data Select, this item cannot be modified because the presently entered signal is selected for editing.

(2) V Freq

It sets the vertical frequency.

When “Current Data Select” is selected in the Original Data Select, this item cannot be modified because the presently entered signal is selected for editing.

(3) Sync Pol

It sets the sync signal polarity. Sync polarities are displayed in the order of “Horizontal/Vertical”.

Sync Pol : N/N Horizontal sync polarity Vertical sync polarity

When you set the sync signal polarity, set it as shown below. Nagative polarity : N Positive polarity : P SOG : SOG

When “Current Data Select” is selected in the Original Data Select, this item cannot be modified because the presently entered signal is selected for editing.

(4) H. Total Pixel

It sets the total number of dots within a single horizontal cycle. This setup value becomes the default value of the user menu “Total H Pixel”.

You should set in a way that number of H. Total Pixels is equal or more than sum of (H. Active Pixel +H. Sync Pixel +H. BP Pixel).

2-8

PFM-32C1/32C1E

(5) H. Active Pixel

It sets the horizontal resolution power.

(6) H. Sync Pixel

It sets the number of dots of horizontal sync signal.

(7) H. BP Pixel

It sets the number of dots during the horizontal back porch.

(8) V. total Line

It sets the total number of vertical lines.

You should set in a way that number of V. Total Line is equal or more than sum of (V. Active Line + V. Sync Line + V. BP Line).

(9) V. Active Pixel

It sets the vertical resolution power.

(10)V. Sync Line

It sets the total number of lines of vertical sync signal.

(11)V. BP Pixel

It sets the number of lines during the vertical back porch.

(12)Clamp Posi

It sets clamp pulse position. The clamp pulse position is set starting (when data is

0) from the trailing edge of the horizontal sync signal. When this data is increased, picture moves toward the picture area. The clamp pulse generation position Tcp is given by the equation below starting from the trailing edge of sync signal. Tcp = Clamp Posi/(Horizontal sync frequency x H. Total Pixel) [seconds]

(13)Clamp Width

It sets the clamp pulse width. The clamp pulse width increases starting from the position that is set by the Clamp Posi. When this value is increased, the clamp pulse width is widened in the direction toward picture area. The clamp pulse width Wcp is given by the equation below. Wcp = Clamp Width/(Horizontal sync frequency x H. Total Pixel) [seconds]

(14)Format Flag

It sets ON/OFF of the following respective items in units of bit.

00000000 1 : ON

1234 0 : OFF

Upper 4 bits are not used.

1 Setting the IP converter

Set to OFF during normal operation.

2 Setting interlace

It sets the interlace input. ON : When the input signal is the interlaced signal. OFF : When the input signal is the progressive signal.

3 Setting to enable the “dot adjustment”

It enables or disables the “dot adjustment” in the user menu. ON : The “dot adjustment” is enabled in the user

menu.

OFF : The “dot adjustment” is disabled in the user

menu. If the actual input signal specification is different from the setups of “H. Total Pixel” and “H. Active Pixel” due to fetching the interlace, set this item to OFF.

4 Frame synchronization setting

It sets synchronization setting of the picture input to scan converter. ON : Vertical sync of PDP panel synchronizes with

the input signal. OFF : The PDP panel display signal is no more

synchronized with the input signal. When the

motion picture is going to be displayed, set this

item to ON.

This item can be set to ON only when the vertical frequency of input signal is in the range from 50 to 60 Hz.

(15)Picture Mode

It sets the picture quality mode. Select the desired mode from “Standard”, “Vivid”, “Use1”, “User2” or “User3”. This setting becomes the default value of the “Picture Mode” of user menu.

(16)Color Matrix

It sets the color difference matrix when the color difference component signal is input. Either “12” or “13” can be set. 12 : In the case when the signal conforms to SMPTE293M. 13 : In the case when the signal conforms to SMPTE294M.

(17)Zoom Mode

It sets the wide selection. Select the desired mode from “Expd. 4/3”, “Letterbx”, “Restore”, “Subtitle” or “4/ 3”. This setting becomes the default value of the “Picture Quality Mode” of user menu.
