Daktronics TI-2020 Multipurpose Track & Field LED Timing Display - Manual (Page 23)

Controls & Timing Functions 17
9. Agility Timer (with normally closed Start and Stop)
Time will display as MN:SC.TH.
With the display reset to 0.0, 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 closed closure.
 STOP input will look for a normally closed closure.
 HORN input will look for a normally open closure.
 RESET input will look for a normally open closure.
10. Self Timer (with special reset/start and normally open stop)
Time will display as MN:SC.TH.
When the START input is closed, the display will reset to 0.00. When the START input
opens the clock will start counting. Pressing STOP will freeze the time on the display.
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.
This mode also has the ability to program a countdown to start. Press RESET once to
reset the display to 0.00. Press and hold RESET. After two seconds the PR:(current
program #) will display for one second, then the countdown time will display. If 0 is
showing, the display will start counting up from 0. If for example the number 10 is
showing, the display will start counting up. While still holding the RESET switch, toggle
the START to get the minutes, toggle STOP to get the seconds.
Note: An All Sport ® control console or an OmniSport ® timing console can be connected to the
TI-2020 or TI-2021
to control it, but the display is then limited to being an output device
rather than the self-contained timing system for which it was designed. Also, the seven-digit
TI-2021 may be used for field events. In those modes, the display must be connected to an
All Sport 1610 console.
