810D Data loading WINPCIN Transmission error

Dear All
We have bought a new CCU card for our 810D PCU20. So no hard disk
We have tried to load the BACKUP PLC, NCK with WINPCIN .

The software starts loading. Both HMI and WinPCIN shows the percentage. But after some moment data transfer HMI shows an error:
RS232C transmission error has occured.
That time baudrate was: 9600
When again do the same loading with baudrate 1200
Progress a little bit more but then Same error occured.

But when I use barudrate 300, then data loading progress . But at last it shows the same error while the loaded around 90%.

One other PLC data is not loading even for baudrate 300. I have put S4 to position 2.

I have given reset to plc and nck correctly. Like S4 2 3 2 3 2. And S3 1 reset button.
Can anyone please give me some suggestion how to solve this problem
