Daktronics C44 - Manual (Page 31)

C-44 Race Timer 3-3
Operation
1. General Disqualifications (DSQ)- Disqualifications are infractions manually
entered by the operator <ALT><F1> (left lane) or <ALT><F9> (right lane).
These include unsportsmanlike conduct, intentional delay of run, and others as
determined by the officials. The C-44 handles DSQ's in the following way. If
one driver is disqualified, the other driver automatically receives the win. If
both drivers are disqualified, the driver with the least severe infraction wins the
race. To determine the severity of an infraction, see the race officials.
Infractions may be canceled manually by the operator: <ALT><F4> (left lane)
or <ALT><F12> (right lane).
2. Crossing Lane Boundary Lines (OB)- Leaving lane boundary lines is an
infraction of the rules. If the operator is notified that a driver has left the driving
lane, the operator enters an out-of-bounds (OB) <ALT><F2> (left lane) or
<ALT><F10> (right lane). The driver who leaves the driving lane is
disqualified, the other driver automatically wins even if his or her car leaves the
driving lane during the remainder of the race, unless a more severe infraction
occurs.
3. Fouls (red lights)- A foul (or red light) is caused when a driver crosses the
starting line before the green light is on (negative reaction time). The C-44
automatically senses a foul, if one has occurred. When a foul does occur, the
driver who fouled is disqualified and the other driver receives the win. If both
drivers foul, the driver who fouled first loses the race. Note: When Sure Start is
active and both drivers foul, both are disqualified in accordance with the no deep
staging rule mentioned earlier.
4. E.T. Breakouts- A breakout occurs when the driver beats his or her respective
dial-in. The C-44 automatically detects breakouts. When a breakout occurs, the
driver who “broke-out” is disqualified and the other driver receives the win. If
both drivers breakout, the driver who “broke out” by the least amount of time
receives the win. If both breakouts are equal the driver that crossed the finish
line first is the winner.
5. Which Vehicle Crossed the Finish Line First- The C-44 automatically
determines which driver finishes the race first. This determination is used to
decide the winner when two drivers have equal dial-ins and no other infractions
occur, or when a double breakout of equal time occurs.
6. Not Finishing the Course (DNF)- If a driver does not finish the course, the C-
44 operator manually enters a did-not-finish (DNF): <ALT><F3> (left lane) or
<ALT><F11> (right lane). The driver who did not finish the race loses the race.
If both drivers do not finish, both drivers are given losses.
Both True Win and Breakout are deactivated by pressing their respective
keystroke combinations a second time.
Emergency
<CTRL><F9> will activate the flashing red lights on the tree and inhibit any countdown
of the tree. An emergency message on the monitor will also flash. Press <CTRL><F9>
a second time to deactivate the emergency mode.
There is also an emergency switch on the starter's console (Drawing A-57318), which
will also activate the emergency mode. The emergency mode will remain active until
both the keyboard select on the C-44 and the switch on the control box are off.
