Digital Matter tracking devices cater for a number of different ways to start a trip.
When a device is in trip, it's "Trip Status Flag" will be set in the digital inputs (separate to bit 0).
Input 0 (bit 0) is the IGNITION input and Telematics Guru uses this to work out whether run hours and odometer readings should be incremented.
Hard-wired Ignition Trips
The most common way of doing this is to wire in the physical ignition line to the white wire on the device (the ignition input on Dart, G60, G100) and use this to start and stop trips.
There are a number of different ways that the devices can be setup on OEM Server.
Movement - the device can also use movement trips, where the GPS is used to decide if the device has started moving and the device emulates ignition by setting the ignition input.
Run Detect - the device can look at the external voltage and use different thresholds to determine if the engine is running or not. It will then set the ignition input.
Other - there are other mechanism to emulate ignition depending on the device and firmware, eg Remora can be setup to use accelerometer activity to emulate trips.
If the device detects that it starts moving and it is not already in a trip then it will start a movement trip. If the device is not set up to map movement trips to the Ignition digital input then Telematics Guru sees that the device is in a trip, but the ignition is not set.
In third party software platforms, bit 0 (trip status) of the digital status flags will be set, but bit 0 (ignition will not be set) so we know the device is on the move but the ignition isn't on.
In this case, the asset is not running/in use, so in general the odometer/run hours should not be incremented
To achieve this (not setting the ignition for a movement trip) Disable the emulated ignition input under the Movement Trips tab in OEM.
TG will still show the trip in its Trip List, but it is marked as a Transported trip - meaning that the asset was moved but the ignition was not active. This will typically be the case when a piece of equipment is towed or moved on a flatbed trailer for example.
Asset Transport Report
Telematics Guru has a report that lists all Transported trips for assets. This report is useful to show equipment movement to / from sites.
