GPS trackers

GPS trackers show where a vehicle is, how fast it moves and where it stopped. Use them for vehicle fleets, trucks, vans, machines and equipment. They connect to the internet over the 4G mobile network, with a SIM card. They do not need WiFi.

The serial number starts with t and the family number, for example t2:.

Models

Model	Description
FMC920	Compact 4G LTE Cat 1 tracker, for basic fleet tracking.
FMC880	Water-resistant 4G tracker with high GPS precision.
FMC230	Water-resistant 4G tracker, with an input for a temperature probe.

Families

The app puts the trackers into families. The family depends on the configuration and the sensors that you bought.

Serial	Name in the app	What it adds
t2:	Telt GPS	Position, speed, distance and ignition only.
t1:	Telt GPS+T	Temperature from up to 2 probes, and humidity.
t3:	Telt GPS+EYE	Temperature and humidity from an EYE sensor over Bluetooth.
t4:	Telt GPS+BLE+GI	Temperature and humidity over Bluetooth, and 4 general inputs.
t6:	Telt GPS+BLE+GI+DOUT	As t4, and 2 outputs that you control from the app.
t5:	Telt GPS+OBD	Engine data from the OBD-II port. See GPS with OBD-II.

For the families with temperature, see GPS with temperature.

What it measures

All trackers give:

Reading	Unit	Note
Latitude, Longitude	degrees	The position of the vehicle.
Speed	km/h
Distance Traveled	m
Angle	°	The direction of travel.
Ignition	on / off	See the caution below.
Battery Voltage	V
Last move at	time	The last time the position changed.

Typical uses

• Fleets of company vehicles.
• Delivery trucks and vans.
• Construction machines and equipment that moves.

SIM and subscription

The tracker has a built-in SIM card with mobile data. Usually it comes with data for 6 or 12 months. Before the period ends, renew it with a SIM product from the shop. If you do not renew it, the tracker stops sending data. Its history stays in your account.

See subscriptions.

Installation

The tracker needs no WiFi setup. It needs only power and a claim.

1. Connect the red wire to the positive (+) terminal of the vehicle battery.
2. Connect the black wire to ground.
3. Install the tracker with the “Mount this side up” side up, for a better signal.
4. Claim it to your account with the Device key.

The tracker has two LEDs: Navigate for GPS and Status for power and operation. When both blink about once per second, the installation is correct.

See install a GPS tracker.

Wires

The colours and pins come from the Teltonika drawings.

Connection	FMC920	FMC880	FMC230
Power (+)	Red	Red	Pin 1, red
Ground (-)	Black	Black	Pin 7, black
Digital input DIN1	Yellow	None	Pin 5, yellow
Analog input AIN1	Grey	None	Pin 4, shared with DIN2
Digital output DOUT1	White	None	Pin 8
Other inputs and outputs	None	None	DIN3/AIN2, DOUT2, DOUT3, 1-Wire

The FMC920 has 5 wires. On the FMC920, the yellow wire is a digital input for a dry contact. The platform does not use the grey and white wires.

The FMC880 has only 2 wires. They connect directly to the terminals of the vehicle battery.

The FMC230 has a 12-pin connector (2 rows of 6).

Map and route

• On the device page, the Map item shows the route of the vehicle.
• The route shows for a period of up to 7 days. For a longer period the app shows “Select a shorter range to see the route”.
• The map page shows all vehicles. When you select a vehicle, it shows the route and the stops of the last 24 hours and follows its live position.
• The Stops report shows where the vehicle stopped. A stop is when the vehicle stays still for more than 120 seconds.

See the map and reports.

Settings

• Ignition filter: while the ignition is off, the GPS position does not change and the speed is zero.
• Show map: shows the position on a map.
• Include in summary views: the tracker shows in the summary views.
• Device Description: text that shows as a subheading in reports.

Caution

The tracker finds the ignition state from the change in the battery voltage. When the engine runs, the alternator charges the battery and the voltage goes up. On a hybrid or electric vehicle, the tracker cannot find the ignition state this way. With an OBD tracker, the OBD data confirms the ignition state. Enable the Ignition filter only if Ignition shows correctly. If not, the position can stay the same.

Controls

The t6 family has 2 outputs, DOUT1 and DOUT2. You turn them on and off from the app or with a rule. See controls.

Rules

There are no ready recommended rules for trackers without temperature. The Location (geofence) condition checks if the vehicle is inside or outside an area on the map. The minimum radius is 50 m. See rule conditions and create a rule.

Troubleshooting

• The tracker is offline: the vehicle is at a place with no mobile signal, or the SIM data ended, or the vehicle power is cut.
• The position does not change: check the Ignition filter and Ignition.
• The route does not show: select a period of up to 7 days.
• For general problems, see device offline.

Specifications

All models connect to the 4G mobile network, with a built-in SIM.
