BZR-2000 software is “the complete router control kit”, allowing full configuration, operation and maintenance of an S-BUS system from a single PC terminal. Operating using Windows 95/98 or Windows NT, the software provides multiple graphic display windows for easy operation and management. A full drag-and-drop facility for the configuration of different routing system devices; panels, routing switchers, UMDs, etc., allows multiple data bases to be saved for alternative configurations. This feature is particularly useful when the facilities of an OB vehicle are regularly used for several different series of productions. BZR-2000 can be interfaced to a routing switcher either via the RS-232 terminal of a PC, or as a secondary station using an optional BKS-R5001 S-BUS interface board installed in the same PC. An optional BKV-100 overlay board installed in the PC provides in-picture monitoring of sources and destinations within the routing system.
