MoTeC BRX - Manual (Page 4)

2 Overview
Overview
The MoTeC Lap Beacon consists of a Beacon Transmitter and a Beacon
Receiver.
The Beacon Transmitter is mounted beside the track and the Beacon
Receiver is mounted in the vehicle and connected to a Display or Data
Logging system or to an Engine Management System.
The Lap Beacon system is used to mark the start of a Lap. This can be used
by a display system to show the driver lap times and lap number and can be
used by a data logging system for lap time and start of lap information. The
Lap Beacon may also be used to generate split times by placing multiple
transmitters around the race circuit.
Operation
The Beacon transmitter emits a narrow infrared beam, which is encoded with
a number that will only be detected by a receiver with the same number.
When the receiver detects a transmitter with a matching number a signal is
sent to the connected device in the vehicle, typically a MoTeC ADL
Dash/Logger or a MoTeC ECU.
