Avoiding Potential Problems With Multiple Controls (G2) - Fairplay MP-70 User Manual

A
VOIDING POTENTIAL PROBLEMS WITH MULTIPLE CONTROLS
In facilities where one or more scoreboards are already synchronized to the
signal of one wireless MP-72/52 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 both operate
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-72/52 control set for ALL SCBDS.
This will result in the situation illustrated below:
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. Fortunately, your control
includes the capacity to broadcast on 16
channels, and so the maximum number of
wireless controls that can be used within any
local vicinity is 16.
You can avoid garbling these transmission
signals by setting up the controls in one of two different fashions:

The recommended method of operating multiple scoreboards from one wireless
control is to use the SEL TRANSMIT
mode and tune the control and
scoreboards to the same channel. As
displayed below, the Court 1 scoreboards
and control are tuned to channel 4 and the
Court 2 scoreboards and control are tuned
to channel 7. Keep in mind that this
arrangement will require you to physically
change the channel at one of the
scoreboards of both courts if you ever
want to operate all four scoreboards
independently with four wireless controls.
On the other hand, the benefit of this setup
is that if either control ceases transmitting, the scoreboards that particular control
was operating will not lock on to the signal from the other control.
