Wireless segment
Setting Up Wireless:
Locate the MP-70/50 wireless control in a place where it and the receiving device is within
range. The maximum range for indoor scoreboards is 300 feet; for outdoor scoreboards it
is 1,200 feet. Be sure and rotate the MP-70/50’s antenna to the full upright position when
using the controller. Otherwise, you may reduce your control’s transmission range.
• Ideally, you should not have to change the MP-70/50 wireless settings; however, the additional
information is provided, if you need to verify that the control is communicating with the score
-
board.
Selecting transmission modes
The MP-70/50 can operate in one of two (synonym for transmission mode). Select one of
the following two transmission modes:
• SELECT CHANNEL mode (SEL) - A mode where you can operate more than one display
with more than one control, simultaneously, without them interfering with one another.
• ALL SCOREBOARDS mode (ALL) - A mode where you can synchronize multiple scoreboards
to one control.
The data link can operate in either:
• HIGH POWER mode - A mode where your control broadcasts a signal to the display at its
maximum available power output. This mode is preferable for most circumstances.
• LOW POWER TRANSMIT mode - Used for system testing.
Viewing your settings
To view the radio transmitter setting of your control, hold down the SHIFT key and press
the
BAT/RF key. If you have a battery-operated control, hold down the key a second time
to display your settings (the first screen you will see will be your percentage of power
remaining in your battery).
Selecting and changing channels
You can also change your channel setting by turning the control off, hitting the SHIFT+9
keys, and then turning it back on again. You will see a series of three questions, the last of
which will ask you to select a channel. Make sure that the channel you pick for the control is
the same that you have selected for the radio receiver in your scoreboard. Keep in mind that
selecting channels 0, 14 (E) or 15 (F) will disable the radio transmitter in either the control
or the scoreboard.
Verifying channel selection and signal lock
Your channel should display on the scoreboard for 30 minutes after you have powered it
up. After this, portions of the LED should display in sequence. If you cannot tell what chan-
nel your scoreboard is set up to receive, you will need to find its signal lock. Do so with the
following sequence:
• If you are running an indoor display, first set your control to ALL SCOREBOARDS mode.
Then follow the instructions below.
• If you are running an outdoor display, you can verify its signal lock by holding the SHIFT
key, then pressing the 9 key. Skip the first two prompts, until you get to the SEL CHANNEL?
prompt. Then, enter all of the possible channel numbers, starting with channel 1, and
working up to channel 13.
