BESTview for the BE1-BPR, Version 1.02.01 can be downloaded.

BESTView application software provides a simple terminal interface to communicate with the BE1-BPR Breaker Protection Relay, retrieve and display COMTRADE oscillographic fault data, and provide a remote front panel interface.

This software is not required to communicate with the relay. However, it combines the functions of a number of separate software packages into one program that is optimized for the BE1-BPR relay.
