The LAP receiver
The lap receiver may be infrared or magnetic and is used to recognise a lap
marker. The Optic receiver requires an Infrared Transmitter (beacon), at the side
of the track; for magnetic receiver, the track must have a magnetic strip installed.
The Magnetic receiver has to be
installed on the floor of the kart, with
two tyre wraps. The arrows on the
magnetic receiver need to point to
the front and rear of the kart
The Infra Red receiver has to “see”
the transmitter placed on the
trackside; the grey point is the
receiver eye.
The MyChron 3 automatically recognises the lap receiver ( optic or
magnetic ) and so no beacon type configuration is needed.
