OPTIONS Menu
Several option settings are available to fine tune the scoreboard system to your needs. These
settings are saved in the control. They are remembered even if the control is turned OFF or the
batteries removed. When a control turns ON the scoreboard, these settings are sent to the
scoreboard and are used to define how it operates. This allows each coach or group to have their
own control with its unique option choices, thus eliminating the need to set up the options every
time the scoreboard is used. For example, Brightness (Baseball – day time) (Soccer – night time).
It is also possible to use more than one control to operate the scoreboard. For instance, the Time
can be controlled by one person while someone else operates the rest of the scoreboard with
another control.
Standard Options
The options key can be used to access the following features. Each press of the options
key moves you to the next option screen. When all options screens have been accessed
you are returned to the main screen.
Note: In this illustration the cursor indicates the default factory settings.
Allows you to select the Brightness Level of the
scoreboard. (Bright or Dim)
Allows you to change the direction time counts
Some scoreboards (timers) that this MPCX is compatible
with have a horn. It can be used to sound at the end of
time. This enables or disables that function
Reports the condition of the batteries in the control.
Allows you to check signal strength when connected to a
receiver.
Used as an indication of reliability of communications.
Affected by distance, battery condition, obstructions and signal
interference.

Advanced Options
This menu option allows you to access settings that affect how
the control operates. Generally, these settings need not be
changed and should only be changed by an experienced operator
or under direction from the Nevco Service Department.
Press the following key sequence:
to gain access to the following additional menu items.
Or
Press the OPTIONS key to return to the main screen.
The Security setting is used to allow multiple controls to
simultaneously operate the scoreboard.
With the Security set to (+)ON, the scoreboard will ignore all
other controls and can be operated only by the control that turned
it ON. When this control is turned OFF another control can be
used to turn the scoreboard ON. Should the batteries go dead or
the 1
st
control leave the area – Power must be cycled to the
scoreboard to allow another control to operate the scoreboard.
If the Security is set to (-)OFF, multiple controls can be used to
operate the same scoreboard or scoreboard system. This allows
one person to operate part of the scoreboard, such as the clock,
while someone else operates the rest of the scoreboard with
another control. Allow each control to establish communications
with its receiver(s) (Greeting screen disappears) before powering
ON the next control.
Note: Set the Security of ALL controls used in a multi-control system to
(-)OFF.
Note: All controls need to be configured for the appropriate scoreboard model
group and linked to the same receiver(s).
Note: The control display will only update when keys are pressed.
Note: Make sure all controls of a multi-control scoreboard system are
powered OFF before starting the system. Power ON the system receivers,
then, power ON the control that will determine the scoreboard attributes
(Brightness Level etc.). Next; power ON the remaining controls. Please allow
time for each control to complete its powering ON process (main screen
appears) before turning ON another control.

This menu option reports the number of receivers the control is
currently linked to (0/0), and the number of receivers on its “Link
To” list (0/0). The option also allows you to link a control to a
scoreboard (receiver) or group of scoreboards (receivers). This
link procedure is required only at the time of installation, when
additional controls are added to an existing system, a change to
the system configuration is needed, or a control or receiver has
been repaired or replaced.
An MPCX control can operate up to eight scoreboards (receivers)
in a dual type configuration. (All scoreboards must be in the same
model series).
Procedure to mate a control and receiver(s)
Step 1. Insert the batteries included with the MPCX control or turn the control ON by pressing
Step 2. Power up one to eight receivers using the 9V wall plug-in power supply provided with
the receiver. Because all receivers powered up and within range of this control will be
linked to this control with this procedure, power down all receivers not to be mated with
new control.
Step 3. Press the button until the display reads
Step 4. Enter the “Code” with the buttons in the sequence
Step 5. Continue pressing the button until the display reads
Step 6. Press the button. The control will link to all receivers in range.
Step 7. This process could take as long as 3 minutes. The control will automatically reset when
linking is complete and each scoreboard connected to a “linked” receiver will light.
Repeat steps 3 – 5 in the “Re-Mating” procedure below to ensure the correct number of
receivers are linked indicated by 0/0 on the “Link Control screen”. The 0/0 on this screen
indicates how many receivers are found / how many receivers are linked.
If more receivers than intended are linked to the control, then power down any MPCX
receivers in the area that are within 2000’ and repeat the process. If you cannot find these
receivers, or they are located on an adjacent property, you may have to perform this
process in another location.
This process creates a list of receivers in the control. The control can only communicate
with receivers on this list. The list remains intact even if the batteries are removed from
the control. During normal operation (with any or all receivers ON), when you turn the
control on, it searches for receivers on its list and the scoreboard(s) will light.
Note: During normal operation, the receiver should always be powered ON before the control. In a multi-control
system, the controls must be powered ON and allowed to find the receiver one at a time. Wait about 30 seconds
between powering-up controls.
