Lap Timing / GPS
Overview
The Lap Timing / GPS Tab provides configuration of lap timing.


Lap Timing Mode
Several pre-defined channels are automatically created if the Display Module supports lap timing. See Lap Timing Channels .
Beacon
In this mode, the beacon input is connected to a lap timing beacon receiver.
Standard
The lap timing outputs are updated as appropriate every time the beacon input is driven low.
AIM
If using an AIM beacon receiver, select AIM under Beacon Type.
AIM beacons have a slightly different output to other beacons; 3 pulses within 10ms must be received by the Display Module to register a beacon event.
Average Speed Setup
Input for average lap speed and predictive lap
Select a vehicle speed here. This will be set to the predefined Speed Input channel by default. Speed Input offers a single place to identify the speed channel and may be configured on the Speed / Odometer / Trip Setup page.
Use Speed Input here and set a common speed channel on the Speed / Odometer / Trip Setup page.
GPS Mode Setup
In this mode, a button (to ground) is connected to the beacon input.
Pressing the button (i.e. grounding the beacon input) for at least 500ms sets the location of the GPS Start/Finish line at the point the button was initially pressed, provided valid GPS data is being received by the display.
When the finish line is crossed again with the GPS Course within 90 degrees of the start finish line, a new lap is triggered.
For GPS mode to work, the outputs for GPS Longitude, GPS Latitude and GPS Course (all in degrees) must be specified together with the width of the track in metres. This should normally be a couple of metres wider than the actual track.
If using the serial input for GPS, these entries will be automatically populated.
The GPS Start/Finish position is stored between sessions and only changed when setting a new start/finish line.
Uploading a setup or uploading new firmware will reset the start/finish line.
If a speed input is specified, the average lap speed and predictive lap timing outputs will function.
