Daktronics TI-2020 Multipurpose Track & Field LED Timing Display - Manual (Page 22)

16 Controls & Timing Functions
5. Game Clock
In this mode, the clock is set in MN:SC.TH format. The display counts down from
59:59.99 to zero, rolls over to 59:59, and continues counting. Or, if a time is programmed,
the clock counts down to the programmed time, stops at zero, and sounds the horn.
A setting of 0 tells the display to count down from 59:59.99 to 0, roll over to 59:59 and
continue counting. If another value is set, from 00:00 to 99:59, the set value is the number
that the timer will go to when the RESET switch is pressed. When START is pressed, the
timer count downs, stops at zero and sounds the horn. If a STOP input is received
during a countdown, the display stops on that time. Next, either press START to
continue counting, or press RESET to go back to the preset time.
 START input will look for a normally open closure.
 STOP input will look for a normally open closure.
 HORN input will look for a normally open closure.
 RESET input will look for a normally open closure.
6. 12-Hour Time of Day
This mode programs the time of day using a 12-hour clock. In this mode, the display
shows time in HR:MN:SC format.
The display will keep time in 12-hour format, starting from the preset value. The switch
inputs are used only to set the time and mode of operation.
7. 24-Hour Time of Day
This mode displays time of day using a standard, 24-hour military clock. In this mode,
the display shows time in HR:MN:SC format.
The display will keep time in 24-hour format starting from the preset value. The switch
inputs are only used to set the time and mode of operation.
8. Agility Timer (with normally open Start and Stop)
Time will display as MN:SC.TH.
With the display reset to 0.00, a START input will start the display counting. The STOP
input will be disabled for the first five seconds. Additional START inputs will be ignored
until the clock is RESET to 0.0. Pressing STOP freezes the running time on the display to
a hundredth (0.01) of a second. RESET sets the clock to 0.00. Pressing the RESET switch
again would return the clock to the previous time. The HORN input manually sounds
the horn.
 START input will look for a normally open closure.
 STOP input will look for a normally open closure.
 HORN input will look for a normally open closure.
 RESET input will look for a normally open closure.
