The Derby Magic test track timer uses 3 ‘AAA’ batteries for power.  The batteries are installed on the
battery holder on the back of the timer assembly.  There is an ON/OFF switch located on the top of the
timer and a green status LED.  The function of the status LED is as follows:

  •      When the timer is turned on and/or the start gate is in the down position, the status LED will flash.
  •      When the start gate is up and the timer is ready to race, the LED will be off.
  •      When the run is being timed, the LED will be on.
  •      When the run is over, the LED will be flashing and the run time will be sent to the computer via the
RS-232 serial cable or USB to serial converter cable.
