RaceAmerica Wireless Drag Racing Scoreboards
PRODUCT OVERVIEW
RaceAmerica Drag Race Scoreboards are a
microprocessor controlled system based upon the
7-segment format display digit using the latest
technology Ultra-Bright LEDs. The scoreboard
utilizes a wireless link to receive data to be
displayed. The wireless link is precongured
for use with RaceAmerica two lane drag timing
systems (models 2650 XL Advanced, 2900/2910
XL Professional, and models 2700/2710 XL
Wireless). Each scoreboard contains its own
microprocessor to analyze the data string received
and correctly display the desired race results (e.g.
left/right lane, speed, ET, etc.).
Race results to be displayed are selected
through DIP switches located on the rear panel of
the scoreboard or congured remotely with the
XLscore Pro software and/or 2700 XL wireless
console.
All Scoreboards can display Reaction
Time, Dial-Ins, Speed and ET, Time of Day and
a countdown clock for intermission sessions.
Multiple race results can be displayed in sequence
as a race is run; Dial-Ins, then RT, and lastly speed
and ET. A ve inch scoreboard can be used as a
Dial-In board at the starting line with or without
larger scoreboard systems. Brightness control is
available with 2700/2710/2900/2910 systems.
A separate WIN light option is available
for each scoreboard system. The WIN light is
connected to the scoreboard with a 10ft cable
for power and data. The WIN light will ash for
the winning lane. Wireless Win Lights are also
available.
Data communication to all models is via
internal wireless data link units (requires timer side
wireless transmitter). Multiple scoreboards can be
daisy chained down the track for spectator viewing
and controlled from a single wireless transmission.
Scoreboards are available in single or dual
line formats in fteen and twenty-four inch digit
heights for viewing up to 1000 ft/301M away.
NOTE: THESE PRODUCTS USE ULTRA-
BRIGHT LED TECHNOLOGY. DUE TO THE
BRIGHTNESS LEVEL OF THIS DISPLAY,
CARE SHOULD BE TAKEN, AS WITH ANY
BRIGHT LIGHTING SOURCE,TO AVOID
PROLONGED VIEWING AT CLOSE RANGE
AND SHORT DISTANCES. AS WITH ANY
BRIGHT LIGHTING SOURCE, VISION MAY
BE AFFECTED SHORT TERM SIMILAR TO
CAMERA FLASHES.
SCOREBOARD SET-UP
Each scoreboard model and race track
have unique requirements; see suggestions and
instructions with each respective model in this
manual. Hard mounting suggestions are provided
for each enclosure.
STEP 1 - Mounting
Each scoreboard contains mounting PEMs
as shown in Figure 8 for 24in/61cm tall digits and
Figure 9 for 15in/38cm tall digits.
STEP 2 - Congure the scoreboard
The scoreboards ship from the factory
congured and labeled, no other conguration is
required.
STEP 3 - Connect the interface

Gland
POWER CONNECTIONS
Power is supplied through the POWER
INPUT box located on the backside bottom left
rear corner. Models are available powered by
either 110VAC/230VAC or 12VDC or 24-30VDC.
AC power can be connected with an AC power
cord using the watertight compression gland
shown in Figure 1 using a standard 3-conductor
power cord.
L = live or hot side of AC power
N = neutral side of AC power
G = ground lead of AC power
Power can also be conduit connected by installing
a 1/2in (Figure 2) or 3/4 (Figure 3) by removing
the compression gland. The 3/4” conduit xture
is connected to the matching hole in the cabinet
metal. The compression gland can remain in
place to provide a watertight connection. DC
power is connected to the terminal strip for
12VDC powered equipment and 24VDC powered
equipment. Figure 4 illustrates the typical
installation for 24VDC powered equipment. An
external chassis ground connection is provided
and should be connected to a grounded wire for
permanent installations. DC powered models will
accept 12VDC or 24-30VDC but not both.

INTERNAL DIP SWITCH SETTINGS
All scoreboard models have two banks of eight
DIP switches (S1 and S2) located inside the unit
numbered from 1 to 8 and can be switched ON
or OFF. Access to these switches require partial
dissassembly of the front of the scoreboard and
therefore are preset at the factory.
The ON position is indicated on the switch
itself. Each switch function and setting are
discussed below. Cycle power OFF/ON after
making any changes.

SCOREBOARD MAINTENANCE
The drag racing scoreboards do not require
any maintenance to maintain proper operation.
The scoreboards are sealed from moisture for all
electrical and data communicatiions connectors.
To clean the red lens, use a non-abrasive
cleaner with a soft cloth. This will keep the
protective lens clean and maximize visibility and
clarity of the digits. If the red lens is soiled with
mud or dirt, gently remove the grit using a soft
cloth/water being careful not to press when wiping
to avoid scratching the red lens acrylic material.
SPARE PARTS
Further to minimize race program
interruptions, RaceAmerica recommends some
spare parts. Related cables for the Scoreboard
should be in considered. Contact RaceAmerica
for availability and pricing of spares items.
SUPPORT AGREEMENTS
Support agreements are available from
RaceAmerica providing Telephone Assistance on
technical issues and operational questions, repair
and/or replacement of hardware failures, Software
and Firmware updates and bug reporting. Contact
RaceAmerica for more information and pricing of
