Single Controller System
In a single controller system, all radio receivers and all scoreboards receive signal from the same console at all times. The default channel and broadcast group settings on the receiver (“b1C1”) are not typically modified. This type of system is often used for football fields or basketball courts with a primary and auxiliary scoreboard displaying the same information at each end of the facility.
Multiple Controller System with Single Broadcast Group
In a multiple controller system with a single broadcast group, there may be one console for each scoreboard and/or one master controller that can run every scoreboard at one time or take control of a specific scoreboard. An example of this type of system is a gymnasium with multiple scoreboards and shot clocks.
