The Sony BZR-IF830 4093 x 4093 Control Software can be installed into the HKSP-R80/R81 Routing Switcher Controller board. The Software can expand the S-BUS space up to 4093 x 4093 as well as control multiple primary stations. Each primary station can control any size of S-BUS space under 1024 x 1024 and the S-BUS space can overlap with other primary stations. This allows control risks to be minimized.
