A
VOIDING POTENTIAL PROBLEMS WITH MULTIPLE CONTROLS
In facilities where one or more scoreboards are already synchronized to the
signal of one wireless MP-70/50
transmitting in ALL SCBDS mode,
that control will also transmit to any
other scoreboards that you set up
within its proximity - regardless of
what the channel setting of the new
scoreboard.
In other words, if you have a
situation where two wireless
scoreboards are operating on their
own basketball courts, and are both
operated under one control in ALL
SCBDS mode, you will not be able to
add and operate a new scoreboard
independently, merely by using
another MP-70/50 control set for ALL SCBDS. Instead, all of the scoreboards will
display scrambled information, because each will not be able to discern which is
its “correct” signal.
The reason for these garbled signals is that the wireless specification doesn’t
allow the simultaneous use of more than one wireless control set to one
particular channel. A situation where two or more controls are located within each
other’s range and set to transmit on the same channel will produce competing
signals. When this happens, the scoreboards will attempt to display both of these
competing signals, resulting in garbled, unintelligible digits. Fortunately, your
control includes the capacity to broadcast on 14 channels, and so the maximum
number of wireless controls that can be used within a local vicinity is 14.
Instead, you can avoid garbling these
transmission signals by setting up the
controls in one of two different fashions:
