the photocell and the reflector is 15 metres.

Max 15 m

4.1. CENTERING

Centering takes place in the following way: when switched on, the photocell emits a continuous

BEEP, pointing the photocell on the reflector, the BEEP stops, thus indicating correct centering.

5. RADIO TRANSMISSION

The LinkGate-Light system incorporates special technological features to ensure maximum

reliability in the transmission of acquired impulses.

5.1. DIGITAL TRASMISSION OF IMPULSES

EncRadio-Light transmits a set of data (no longer a single impulse!) that contains a large quantity of

information. In particular, the following are transmitted:

• The transmitter’s code

• The type of signal transmitted (Start, Lap number or Stop, which can be selected with the Signal

Type switch)

• How long ago the event took place.

To the set of data are added numerous control codes and error self-correction codes which prevent a

signal from being incorrectly interpreted during reception.

All the data (information + control codes) are transmitted 16 times, in order to reduce the possibility

of reception failure.
