How to fix the Connection Issue between PIWIS3 Software and VNCI PT3G

When your PIWIS3 software is unable to connect to the original PT3G/PT4G device or the VNCI PT3G device, it may be due to a tampered or replaced PIWIS3 software driver. In order to rectify this issue and restore the connection, you will need to follow the steps outlined below:

The steps to restore the original PIWIS3 driver are as follows:

1. Begin by downloading the original driver, ensuring that you have the latest version available (v3.5.6).

2. Open the location of the PIWIS3 driver on your computer. This can usually be found at the following path: D:/PiwisApps/VCI/Actia_64/XS_D_PDU_API_64/. Once you have located the driver folder, delete all files present within it.

3. Copy the downloaded original driver file to the same location that you just cleared. Paste it into the XS_D_PDU_API_64 folder.

Windows Registry Editor Version 5.00


“Image Version”=”3.5r06-13787-108”
“Image File”=”D:/PiwisApps/VCI/Actia_64/XS_D_PDU_API_64/PT3G-VCI-3.5r06-13787-108-20220801”
“Module Version”=”3.5.6”
“Module File”=”D:/PiwisApps/VCI/Actia_64/XS_D_PDU_API_64/PT3G-VCI-D-PDU-API-Fw.tgz”
“Image Boot Timeout”=dword:0001d4c0
“Update Timeout Default”=dword:00003a98
“Update Timeout Image”=dword:00030d40
“Update Timeout Module”=dword:0000afc8
“Module Name”=”D-PDU-API”

4. Next, you will need to modify the registry settings. Copy the provided registry contents and save them as a text file with a “.reg” suffix. Once saved, double-click the file to run it. This will update the registry settings accordingly.

5. After completing the above steps, you can now connect your VNCI PT3G or the original PT3G/PT4G device. Run the ACTIA_D-PDU_API_Tester.exe program and click on the “Start” button to initiate the connection. If all communication protocols are successfully passed, it indicates that the original device driver has been fully restored to its normal state.

By following these steps, you should be able to resolve the issue of the PIWIS3 software not connecting to the VNCI PT3G or the original PT3G/PT4G device. Restoring the original driver ensures proper functionality and enables a smooth connection between the software and the devices.
