SOFTWARE UPDATE AND

AUTO CALIBRATION PROCEDURE

Vestel Electronics

2006

( ! ) Important Note:

It is necessary to load LPT Driver, Visual I2C program and some .dll folders for

starting software update process. Please load that important folders.

1) Setting up the LPT Driver

- Please set up the Setup_LptDrv….exe

- Please copy the .dll folders into the C:/Windows/System32.

- Please make a folder as C:/ProgramFiles/Micronas and create LptDrv into this

Micronas folder. (System creates all of that folders autometically, when

Setup_LptDrv….exe is loaded)

- When Start→Programs → Micronas → LptDrv → LptDrvTest.exe is opened, a

window appears like below.

If "=> Lpt Driver test OK!” string is visible, There is no problem for parallel port.

But if “Test with Error” string is visible instead of “OK”, true .dll folders must be

loaded. (given by Vestel). If the problem already continues, please refer to the IT.

2) Setting up the Visual I2C

- Please set up the Setup_Visual_I2C_v3-2-0.exe

- Please create a folder as C:/ProgramFiles/Micronas and create Visual I2C folder

inside that Micronas folder. (System creates all of that folders autometically, when

Setup_Visual_I2C_v3-2-0.exe is loaded.)

- Please copy exe files to C:/ProgramFiles/Micronas/ Visual I2C folder like below

steps,

a) Please make unzip vct49xyi_27Feb04.zip content to the

inside C:/ProgramFiles/Micronas/ Visual I2C. Folder must be like below.

b) Vcti_start folder can be made shortcut at desktop.

System Tools:

1) Visual I2C program

2) LPT Driver

3) .dll folders

HW Tools:

1) Software Update Card (17PRG24)

2) Parallel Port Cable (for VCTI microcontroller updating)

3) Serial Port Cable (for E2PROM updating)

4) Scart Cable

Connections:

VCTI Microcontroller Programming

***Firstly, push the switch1 button that is located on the programming card. (switch2

have to be off)

*** Please turn on the TV . After the TV image was visible, press “menu” and “1905”

by using remote control. Please connect both of the scart connectors (TV scart1

connector and programming card connector) by using scart cable. Please connect

both of the parallel port connectors (computer parallel port connector and

programming card connector) by using parallel port cable. Then, please open the

Micronas VCTI49XYI programming software interface.

*** After this folder was opened, a window will appear as below. Please choose

window, find window options in turn in order. Please write “bootloader” in selected

window (or click the TVT button as below), searching will start automatically. At

the end of the searching process, please double click to bootloader.bat.

*** Please click over to the “bootloader” icon for prepearing to loading. TV will  oto

stand-by mode if bootloder process was achived. And below window will appear

on the tv screen.

***If bootloader process was failed by using this button, another process is getting to

bootloader mode manually by using below window.

***After bootloader process, please pass to the reading process.

***After the reading process, bootloader version will come as 21 or 22 that depends

on bootloader version of IC.

***After that, please click to “erase flash” button that was determined by yellow color

as below.

***Set the options as to=0x7FFF and reclen=16. Please choose the path of binary file

by using “NAME” part.

*** As finally click to over of the Load BinÆ Flash icon .Loading will be started

automatically.

(!) IMPORTANT NOTE (1): If there is a problem as fast loading. Please follow the

steps;

*** Please open the File → Preferences → LPT Preferences. Below window will appear.

***Please make Delay = 10

(!) IMPORTANT NOTE (2): If there is a problem during bootloader process or there is

a message as “No Acknowledge From The Slave”, Please apply the following steps;

-Please turn off the TV.

-Please open the bootloader file.

-Please press bootloader icon and turn on the TV at the same time. You have to do

these process at same time.

(!) INITING NVM:

For initing the NVM (E2PROM);

-Please turn on the TV.

-Please press -turn in order- “menu”,”4”,”7”,”2”,”5”.

-You will see service menu that located on the screen.

-You will see init NVM option at the service menu.

-Get the string of this as INIT NVMÆYES.

-Turn off the TV.

-Thus, Inıt nvm process is over.

E2PROM READING AND WRITING

*** Firstly, push the switch2 button that is located on the programming card. (switch1

have to be off)

*** Please turn on the TV . After the TV image was visible, press “menu” and “2045”

by using remote control. Please connect both of the scart connectors (TV scart1

connector and programming card connector) by using scart cable. Please connect

both of the serial port (RS232) connectors (computer serial port (RS232)connector

and programming card connector) by using serial port cable. Then, please open

the Ponyprog programming software interface.

*** Please control some adjustments.

*** COM port settings can be made from set-up menu.

*** Please click the Device icon for settings. Set as below.

*** Please choose the Device type as 2432-512.

*** For reading process, please click the button that was marked with yellow.

*** After resding process, E2PROM content will appear on the screen.
