HKSP-R80
8-1-2. System Connection
Two possible systems using an S-BUS subnet controller are introduced here.
One is to extend the number of units to be controlled. Another is to separate the system for each subnet to
use the subnets in separate studios. If the system is separated into subnet systems, effects of updating a
program, disconnecting units, operation errors, etc. are limited to only the affected subnet within the
subnet system.
System to extend the number of units connectable
System setup is performed for a system including routing switcher control units connected to the S-BUS
subnet controller (the secondary station) with a control terminal connected to the primary station’s HKSP-
R80.
