"Six disk set" ? PanelBuilder32 (and for that matter, any Rockwell software) hasn't come on diskettes for more than ten years. It's entirely possible that your PanelView terminal firmware is not supported by this old software.
PanelView Standard terminals have a "DCE" style serial port. This is pinned with the Rx and Tx terminals opposite of a standard computer "DTE" port, so you need a straight-through serial cable to connect to the PanelView.
Most of the time, you use the RSLinx Classic communication drivers to connect to a PanelView, rather than the old direct drivers that were part of the PanelView Transfer Utility in the 1990's. Those direct drivers may not work with USB communication converters.
