Basic Operations 25
Each radio receiver will accept data sent from the broadcast channel of its respective
broadcast group. This is selected by setting the transmitter radio (from the console) to the
respective broadcast group (either 1, 2, 3 or 4). Every radio receiver will also accept data sent
from the “Master Broadcast” channel. This is selected when a transmitter (console) radio is
set to Broadcast Group 0 (BCAST 0) and Channel 0.
The channel number and broadcast group set on the radio installed in each scoreboard can be
verified by cycling power to the scoreboard. Approximately seven seconds after power up,
the scoreboard will show the current channel in the scoreboard clock digits. A CXX will first
be shown where XX is the current radio channel number. This will be followed by BXCY
where X is the current broadcast group and Y is the current channel number within this
broadcast group.
There are three different radio scenarios that can be accommodated.
1. Single Controller System:
In a single controller system, all radio receivers and all scoreboards receive signal
from the same All Sport console at all times. The default channel and broadcast
group settings on the receiver are not typically modified. An example of this type of
system is a typical high school football installation.
2. Multiple Controller System w/Single Broadcast Group:
In a multiple controller system with a single broadcast group, there are additional
All Sport Controllers for controlling multiple scoreboards. There is never a scenario
where groups of scoreboards that were run by individual controllers need to be run
by a single controller. An example of this type of system is a softball complex with
multiple fields and a scoreboard on each field.
3. Multiple Controller w/Multiple Broadcast Groups:
In a Multiple controller with Multiple Broadcast (Split Court Operation) system,
there are additional All Sport Controllers that can control multiple scoreboards. The
broadcast group jumper is used to select broadcast group 1, 2, 3, or 4. By changing
All Sport settings to a Broadcast address, a single All Sport Controller can control all
scoreboards or specific groups of scoreboards (defined by the broadcast group). One
example of this scenario is split court operation in basketball installations, where
scoreboards are used to score multiple games at once, but can be grouped together to
show one game if necessary. Refer to the drawings listed on the previous page for
more information.
The All Sport Console will automatically detect when a radio transmitter is installed and will
prompt the user for transmitter settings.
The All Sport Console will show the current transmitter radio status on the LCD when a code
is entered. The following table describes broadcast group and channel settings.
