RaceAmerica Model 2650 Series XL Advanced
is about to start a race. The ET timer for a lane
with a blocked beam will start when the beam is
re-established as the vehicle pulls away. The beam
can re-establish in less than 0.0001 seconds.
RaceAmerica oers several dierent sensor
and emitter models (see Beam Emitter and Sensor
models); depending on a variety of requirements.
See the table of Sensor/Emitter combinations
which operate with the Model 2650 XLAdvanced
system. In general, non-similiar sensor/emitter
pairs will not function correctly. All start line
sensor options connect to the same Start cable
connections; make sure left and right lane
positions are correct.
SET-UP STEPS - 2650 SERIES
The content of this manual is designed to
assist the new system owner with the RaceAmerica
system, however, it is strongly suggested that the
system be set up in a race simulation area without
stretching the cables all out to gain familiarity with
basic operation of the components prior to race
day. This can be done in a driveway or garage.
Walking through beams can simulate vehicles
for purposes of familiarizing oneself with basic
operation.
STEP 1 - Familiarize yourself with the
components pictured in this manual and how they
interconnect. The Track Sensor Interconnect
Cable is congured for connection between the
timer console, starting line, and nish line; cable
drops are pre-congured for the Tree, a Starter’s
Button, 60 Foot times and a Speed trap. Track
lengths greater than 500 foot will be in two cable
segments; outside cables will join at the starting
line. The large round connector connects to the
console and the smaller connectors (RJ12) connect
to the Track Sensors at the start line, 60 foot, speed
trap and nish line as indicated on the cable near
each RJ12 connector. Ensure the correct sensor
is connected at each position (with the matching
emitter opposing it)
STEP 2 - Identify the emitter/sensor
placement at the start line and nish line. The
lane width should be set between four (4) and fty
(50) feet. Layout the Track Sensor Interconnect
Cables on the track site as illustrated on the Track
Sensors/Cabling Diagram pages based on the
options included with the system. Route cables to
avoid vehicle and pedestrian trac. Additionally,
avoid running any of the system cables in conduit
with 110/230VAC power lines as intermittent
failures may occur. Speed Trap sensor spacing is
set to the system requirements to record accurate
speeds. To help in determining initial beam emitter
to track sensor alignment in wide track widths,
use a string stretched between the beam emitter
and track sensor or eyeball a straight line between
units. The system Alignment Mode will be utilized
to verify alignment after power-up.
STEP 3 - Assemble the TREE to the base as
shown in the setup photos. Multiple base plates
may be required for windy racing conditions.
Install ood lamps in the AC TREE models.
STEP 4 - Route the cables, place the
equipment in position. Connect the Track
Interconnect cable. This cable has connector drops
for the TREE, all Track Sensor positions (Start,
60 Ft, Speed and Finish), and the Starter’s Button.
STEP5 - Connect cables for optional Starter’s
Button, Printer(s), PC(s), PODs, Wireless Links
and Scoreboards to the appropriate connectors.
The system will operate without these options
connected. See Connecting Peripheral Devices
for details about these options.
