SIM Cards (usually in the device)

Usually the SIM card comes with the device. Sometimes customers take their own SIM cards.

Only SIM Cards without a pin can be used.

The device is preconfigured for a certain provider, the usage of other SIM cars will not work.

The sim card must pe done in the device, where there is no power connected.

To test a Sim card, if it works or not, an unlocked mobile phone can be used.


Mounting Positions

In-Vehicle Tracker



Mobile Tracker  & Container Tracker

In this case it is only necessary that the device can face the satellite!

Connecting Wires

If there are cables to connect, the following rules apply:

Connecting the Permanent Power Source / Ground

If a power must be connected, the following rules apply:

Connecting Ignition

If the device must be connected to ignition, the following rules apply:

GPS Antenna

The GPS antenna can be fixed visibly on the dashboard or right below the dashboard. The green areas shown below are recommended (close to the windshield):

GSM Antenna

If the device has an external GSM antenna, the following rules apply:

Power Consumption

Please note that external factors might cause the box to enter sleep mode (searching for GPS, reloading batteries).

Different factors (box operations, antenna positions) will cause different power consumption.To avoid total battery depletion after very long inactivity you can add a main power switch that can be installed hidden so that you can disconnect the device from power if needed.

Connecting Digital Inputs / Outputs

Connecting Positive Inputs

Most external signals (alarm buttons, door sensors, ignition, etc) return two states: high or low voltage. Digital inputs should be used to read this information. The figure below shows how to connect alarm button, door sensor, etc.

Different tracking units have different numbers of Digital Inputs. See above for finding the right pin for digital inputs. In cases when sensor output signal is negative an additional relay has to be installed to convert negative signal to positive.

GPS Tracking Units have various digital inputs that can process simple status signals (0 = off, 1 = ON).

Other examples for vehicle signals that could be connected to digital inputs (depending on the vehicle and how you can connect): Ignition, Door/hood open/closed, Seat belt on/off, Fuel tank lid open/close, 4-wheel drive on/off, light on/off.

Interaction between the tracking box digital inputs and the vehicle signal needs skilled professional people (in a workshop) AND the electrical plan of the vehicle. Most workshops know about how and where to connect a digital input to the vehicle. In rare cases (or depending on the vehicle brand and model) you will need a special CANBUS interface to get the vehicle signal safely from the vehicle without interfering the CANBUS. If you are not sure, consult a professional workshop or dealer or search for the vehicle electronical switching plan online:

Connecting Negative Inputs

As it is common in the automotive industriy, tracking devices also have negative inputs

In this case  the ground signal has to be switched instead of the positive voltage.

Connecting Outputs (Open Collector)

The usage of outputs can lead to dangerous situations and needs precaution. The provider EXPRESSLY DISCLAIMS ALL WARRANTIES OR LIABILITIES that could be caused by connecting outputs. The customer bears the risk of any consequential damages.

 Example connection Plan - Negative Input

A possible configuration:

The relay is connected with the OUT 1 cable, that its pulls , if the output is active (in other words when ground is coming over the OUT 1 cable)

If the relay is active, the ignition will not work.

If the relay is not active, the ignition will work.

If the tracking device is not working or would be damaged, the ignition would work!
