Autonomous Decoder
Description Autonomous Decoder
Since 2004, Chronelec has developed autonomous decoders. These decoders allow to manage checkpoints for Rally and Enduro
Each decoder is delivered in a waterproof suitcase with a 12 hours' autonomy battery. A numeric clock panel can be connected to the suitcase in order to display the time of day.
All check time are saved on a SD card. A ticket is printed and given at each competitor's passings. When the checkpoint is closed, reading all passings from SD card allow to compute penality.
This system is used by the FFM (French Federation of Motorcycling) for enduro and rally championships.

3 years warranty
The height of detection transponder depends on :
- The disturbance signal in the loop (Noise)
- The lenght of the loop (5 to 25 m, 16 to 82 ft)
- The width of the loop (more the width is large and more the height of detection increase, and vice versa)
- The sensitivity level of detection (0 means high sensitivity)
