Some addtitional questions at the beginning:

1. What type of device do you use for making backup?

2. What settings do you have in Port init screen?

3. Which port do you use for making backup?

4. What kind of cable do you use to communicate with PC?

Below is the instructions and cable pin out I have always used on our Rj2. Worked for me.

Kfloppy directions TO SEE USB PORT GO TO TOP TASK BAR>>>DEVICES>>>USB>>>SELECT PORT AND DOUBLE CLICK. Turn Off Screen Saver And Hard Drive Shut Down To save program: Open Kfloppy >>> Set comm portt>>> In KFloppy Folder on Desk Top: Create a File, Example: “837_5_18” this is the robot number and the month and year of back up.

On the laptop, sometimes it helps to copy a small file from an old backup into the destination directory, ZERO.TP for example. I then do a directory in the teach pendant 'File' menu to verify that it reads from the destination directory. If you can't read the directory then something is wrong with the setup.
