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:

a. Connect  Parallel port I2C interface to LPT port of the computer.
b. 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\Micronas\Visual I2C\Port_Driver”, following next criteria:.

a. Windows 98/Me (“Setup_LptDrv_v0104_9x.exe”).

b. Windows NT (“Setup_LptDrv_v0104_NT_2000.exe”).

c. Windows Xp/2000 (“Setup_LptDrv_v020201_XP_2000.exe”).

After installing Visual I2C, the new generated file structure should look like this:

3.  Install  Parallel  driver  depending  of  your  Windows  version  from  existing  files  inside  the 

Visual I2C installation folder “C:\Program Files\Micronas\Visual I2C\Port_Driver”, following 

next criteria:. 

a.  Windows 98/Me (“Setup_LptDrv_v0104_9x.exe”). 

b.  Windows NT (“Setup_LptDrv_v0104_NT_2000.exe”). 

c.  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: 

�� If the result is not OK, check inside PC bios:  Parallel Port Mode=EPP 

To  run  VCTp  software  updater  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.
