RaceAmerica 3850B Timer AC4 Owner's Manual page 16

Each finish freezes the running timer and
sends the time to the serial ports (PCs and
displays).
The console operator can use the Manual
Start [3] key to over-ride the track sensor or
when the Status Display indicates the sensors are
disabled [*2].
If a car goes off course and cannot finish;
press 'Did not Finish DNF [9] when the car
should finish and their time will be set to the time
configured in [out Et] (*44####).
If a car reaches the maximum time allowed,
its timer will automatically stop at that number.
This time is configured in [End Et] (*44###).
Use 'All Stop' [*7] to stop the currently
counting timer to reset for another car.
During timing, alignment status can be
checked.
Sensor status is monitored in the background.
When the sensors are properly aligned, the decimal
points by the rightmost character on each line will
flash intermittently (about every three seconds). If
the start sensor goes out of alignment, the display
will show [StArt] [SenSor] [test] [FAiLEd] with
'test failed' flashing to get the operators attention.
Unaligned sensors will cause a sensor trip and
a sensor trip each lockout interval as set in the
CONFIG menu (*44#####). During an out of
alignment situation, turn off the sensors and use
the manual START (3)/FINISH (6) to continue
the event.
Single Beam - Laptimer configuration
T-Link Wireless
Run Single Beam Wireless with Sensors
[OFF] as configured in SENSORS [*2]. Each time
the beam (T-Link 'A') is interrupted, a timer will
stop counting and a new one will start counting.
After each finish/start, the beam is locked out for
two to nine seconds (see *4 CONFIG) to allow
the car to pass through and the dust to clear. A
lap number is assigned to each start on the console
(press/hold [0] to view lap number; press/hold [8]
to view the 'Best' lap).
Each finish freezes the console and sends the
time to the serial ports (PCs and displays).
If a car goes off course and cannot finish;
press 'IGNORE [2] to not count the lap. Use 'All
Stop' [*7] to stop the currently counting timer to
reset for another car.
This mode only operates with 'SENSORS'
OFF ([*2]).
During timing, status conditions can be
checked. RF Integrity and Battery Level status
are available. Alignment status is available on the
'A' T-Link Wireless unit.
Dual Beam - Autocross Solo II
Manual
This manual stop watch type operation works
with Sensors [OFF] as selected in SENSORS [*2].
T-Link 'Z' can be connected but not turned on.
When a vehicle cosses the Start line, press
'Start' [3], a timer will start countiing. When a
car crosses the Finish line, press 'Stop' [6] and the
first running timer will stop. Up to four cars can
start before the first car must finish. Once a car
has finished, another car can start. A run number
is assigned to each start on the console. Cars must
start and stop without passing.
Each finish freezes the highest count running
timer and sends the time to the serial ports (PCs
and displays) until another run starts.
If a run is stopped in error, the operator can
press Continue [5] which will restart the last run
stopped. This feature can restart timers for all runs
on the display without losing any time.
If a car goes off course and cannot finish;
press 'Did not Finish DNF [9] when the car
should finish and their time will be set to the time
configured in [out Et] (*44####).
If a car reaches the maximum time allowed,
its timer will automatically stop at that number.
This time is configured in [End Et] (*44###).
Use 'ALL STOP' [*7] to stop all currently
counting timers when something happens requiring
a rerun of all cars on the track. Run numbers are
not reset. Alternately, 'RESTART' [*0] will reset
the timer to the initial power-up settings.
