The Beacon Receiver (BR2) is the part of the lap timing
system that is fitted in the vehicle. Depending on the other components in the
application, the receiver can be connected using a switched output or a CAN bus
and should be set up accordingly.
Fitting the BR2
The BR2 should be fitted so that the infra red beam hits the
receiver window at a right angle when the car passes the transmitter.
If there are no obstacles between transmitter and receiver,
the range of MoTeC's lap timing system is up to 40 meters. The receiver should
be positioned carefully in the vehicle to avoid the beam passing through tinted
glass or acrylic, which can reduce the range substantially.
