LED LAMPS
A LED or Light Emitting Diode is a rather simple semiconductor circuit which emits light without
producing waste heat. This means, it needs only very little energy, about 5% of a normal light
bulb to produce the same amount of light. We use ultra bright LEDs as warning lamps in the
display unit.
MAGNET STRIPE
A piece of magnet going all the way across the track. Used to trigger the Laptimer as an
alternative to the loop.
MAIN BOX
Most of the electronic is located in the main box. This is the box with all the connectors, memory
and batteries.
MEMORY
A lot of different memory is used for storing the program, setup, lap times and logged data. The
most used type of memory is Flash or EEPROM. Both types are used in this Laptimer.
PROCESSOR
The part of the Laptimer with all the intelligence and calculating power. It is also called a CPU, μP,
μC or just the computer.
PROTOCOL
A protocol is a piece of software that sets the standard for how the systems work. For example
the process for sending data through infrared light is defined in the Infrared Data Association
Protocol – the IrDA protocol.
RECEIVER
The receiver picks up the trigger signal and starts the Laptimers stopwatch. There are different
types of receivers: loop, magnet stripe and infrared. Your Unipro Laptimer supports all kinds of
receivers.
TRIGGER
The Laptimer trigs when it passes the finish line. The trigger can be either infrared light, a magnet
stripe or a Loop signal.
TELEMETRY
A way of sending data through the air from the running kart to the pit. It is illegal during official
races and can only be used for training.
