VERY IMPORTANT NOTE:
During the updating time, please don’t use the PC for other purposes, in order to abolish communication problems between TV set and PC.
If TV set was not updated properly, the TV wonÅft have the software to startup again, and you must follow the “I2C method” to update
another time the TV set.
3. I2C Method Description
The hardware tools requirement are:
1. A Parallel port I2C interface with 20 pin to 3 pin cable (Sharp Code: CKIT-0004WJV0).
2. Make the connections as indicated below:
i)
Connect Parallel port I2C interface to LPT port of the computer.
ii) Connect the 20 to 3 pin cable from the I2C interface to the P2306 socket in the main board (XD603).
Before using I2C method is necessary to install Visual I2C software following next procedure.
1. Install Visual I2C release V3.2.3b from file (“Setup_Visual_I2C_v3-2-3b8h.exe”).
• It’s strongly recommended to accept the suggested default folder (“C:\Program Files\Micronas\Visual I2C”).
2. Install Visual I2C VCTp extension from file (“Setup_VI2C_for_VCT6wxyP_v0111.exe”).
• It’s interesting to change default folder to same as Visual I2C (“C:\Program Files\Micronas\Visual I2C”).
• During this installation process is possible to install also a complementary software to manage NVM memories .
This installation is not needed, for this reason uncheck the option when the setup program ask to you. In case of installation it’s interesting to change
default folder to same as Visual I2C (“C:\Program Files\Micronas\Visual I2C”).
3. Install Parallel driver depending of your Windows version from existing files inside the Visual I2C installation folder “C:\Program Files\Micro
    nas\Visual I2C\Port_Driver”, following next criteria:.
1) Windows 98/Me (“Setup_LptDrv_v0104_9x.exe”).
2) Windows NT (“Setup_LptDrv_v0104_NT_2000.exe”).

3) Windows Xp/2000 (“Setup_LptDrv_v020201_XP_2000.exe”).
After installing Visual I2C, the new generated file structure should look like this:
4. Check installation LPT driver using “C:\Program Files\Micronas\LptDrv\LptDrvTest.exe”. After run this software, if LPT driver is installed properly
     must appear this screen:
3.
• If the result is not OK, check inside PC bios: Parallel Port Mode=EPP
To run VCTp software update program, please click over “VCTP” icon from “START\All programs\Micronas\Visual I2C\IC\VCTP” and after Visual I2C
finish their starting process click on “TVT” module. As additional method, it’s possible to create a direct access to “C:\Program Files\Micronas\Visual
I2C\ic\vct6wxyP\vctq_tvt.vi2c” and launch it from Windows Desktop.
