Digital Matter tracking devices cater for a number of different ways to start a trip.
Input 0 (bit 0) is the IGNITION input and Telematics Guru uses this to work out if the a device is in a trip.
Hardware 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. You should consult the user manual for the specific device that you have.
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.
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 setup 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.
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.
