RaceAmerica 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
uses a serial link (RS422/RS485) to receive data
to be displayed. Each scoreboard contains its
own CPU chip to analyze the data string received
and correctly display the desired race results (e.g.
left/right lane, top/bottom position).
Scoreboards can display race results and a
test pattern from the Compulink StarTrak and
Port-A-Tree Silver & Gold Timing systems.
ET, Speed and Dial-ins, etc. are controlled by
the Compulink system or the Porta-A-Tree
Professional software.
Data communication to all models is available
via internal wireless data link units (requires timer
side wireless transmitter).
Multiple scoreboards can be daisy chained
down the track for spectator viewing or controlled
from a single wireless transmission.
Scoreboards are available in single or dual
line formats in fifteen and twenty-four inch digit
heights for viewing up to 1000 ft away. Each
product is addressed for its unique properties in
this manual.
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
STE P 1 - Ass emb le/ mou nt the
scoreboard
Each scoreboard model and race track
have unique requirements; see suggestions and
instructions with each respective model in this
manual. Hanging or hard mounting suggestions
are provided for each enclosure.
Twenty-four inch models are assembled
using the digit position labels located on the top
of each digit (segment is identified by the inverse
printing of its number). A full unit consists of
segments one thru five assembled from left to
right.
Connect the cable to the connector between
each two digits as they are asssembled. A
horizonal and vertical frame structure is required
to mount each scoreboard (see figures).
STEP 2 - Configure the scoreboard
The scoreboards ship from the factory with
the most likely selections enabled. See DIP switch
definitions to change scoreboard positions.
NOTE: IF DIP SWITCH NUMBER 1 (BANK
S1) IS SET TO ‘OFF’ DURING THE POWER
UP SELF-TEST, THE DISPLAY WILL
CONTINUOUSLY LOOP ON THE SELF-TEST
UNTIL SWITCH NUMBER 1 IS SET TO THE
‘ON’ POSITION.
STEP 3 - Connect the interface
Fifteen and twenty-four inch models
must receive RS422/RS485 data. Models with
a Wireless ‘receive’ Link mounted internally are
configured to receive RS422/RS485 data.
A 07-3434 red RS422 cable or timer side
wireless link transmitter are all that is required to
send data to the scoreboards.
Scoreboards without an internal wireless
unit use interface cables containing RJ45 modular
