General Information 

Welcome to the user manual for the Race Timer. The timer consists of hardware that measures the 
race time and software running on a computer that controls the race and displays the results. For 
example the system can be used to time CO

2

 model drag racing cars. 

These instructions apply to: 

 

 

Hardware Version 1.0 

 

Dual Infrared (IR) transmitter option (separate IR transmitters are available is required) 

 

Infrared beams for both the start and end of the track, or, Solenoids at the start of the track 
and IR beams at the end. 

Function Overview 

 

1ms, 1/1000 second timing for accurate timing. This is crystal oscillator 

based electronic hardware timing (the laptop computer is not involved in the measurement 
process). 0.5ms measurement granularity to ensure timing accuracy. 

 

 Drag racing “Christmas Tree” sequencing starting display for real racing 

experience. 

 

 Overhead screen projector (not supplied) display interface supported by the 

laptop for viewing by a large target audience. 

 

 Screen shows dual lane information: reaction time, race time and racing 

speed. All software is included.
