1INTRODUCTION
1.1 Attention
Do not disassemble the device. If the device is
damaged, the power supply cables are not isolated or
the isolation is damaged, before unplugging the power
supply, do not touch the device.
All wireless data transferring devices produce
interference that may affect other devices which are
placed nearby.
The device must be connected only by qualified
personnel.
The device must be firmly fastened in the predefined
location.
The programming must be performed using a second
class PC (with autonomic power supply).
The device is susceptible to water and humidity.
Any installation and/or handling during a lightning
storm are prohibited.
FM3620 has USB interface;
Please use cables provided with FM3620 device.
Teltonika is not responsible for any harm caused by
using wrong cables for PC <-> FM3620 connection.
1.2 Instructions of safety
This chapter contains information on how to operate FM3620 safely. By following these
requirements and recommendations, you will avoid dangerous situations. You must read these
instructions carefully and follow them strictly before operating the device!
The device uses a 10 V...30 V DC power supply. The nominal voltage is 12 V DC. The
allowed range of voltage is 10 V...30 V DC.
To avoid mechanical damage, it is advised to transport the FM3620 device in an impact-
proof package. Before usage, the device should be placed so that its LED indicators are visible,
which show the status of operation the device is in.
When connecting the connection (2x3) cables to the vehicle, the appropriate jumpers of
the power supply of the vehicle should be disconnected.
Before dismounting the device from the vehicle, the 2x3 connection must be disconnected.

6
The device is designed to be mounted in a zone of limited access, which is inaccessible for
the operator. All related devices must meet the requirements of standard EN 60950-1.
The device FM3620 is not designed as a navigational device for boats.

FM3620 connected to PC creates an STM Virtual COM Port, which can be used as a system
port (to flash firmware and configure the device):

1 –Wire devices for FM3620_C2
One of the realized features is 1-Wire® data protocol, which enables connection of
thermometer (DS1820, DS18S20 and DS18B20) and I-Button type: DS1990A (Figures 8 and 9
show FM3620_C2 and 1-wire® device connection schemes).

Fuel Tank sensors for FM3620_C1 or FM3620_C2
A fuel tank level sensor exists in most cars, which shows the approximate fuel level in the
driver’s indicator panel. It is possible to connect Analog input to FM3620_C1 or FM3620_C2 (if
sensor returns analogue signal proportional to fuel level). As input shares the same PIN with
Digital input 2, FM3620_C1 or FM3620_C2 must be configured to use only one of them. Figure 10
shows the connection scheme to the FM3620 and fuel tank sensor through Analog input 1. After
the connection to the tank fuel level sensor, calibration is needed. Calibration is needed because
most fuel tank sensors are not linear. Calibration is performed by measuring voltage dependence
on volume of fuel in tank.
Figure 10. Fuel Tank sensor connection
Alarm buttons, door sensors, etc.
Alarm buttons, door sensors, ignition, etc. return two states: high or low voltage. Digital
inputs are used to read this information. Figure below shows how to connect alarm button, door
sensor, etc.

In cases when sensor output signal is negative, an additional relay has to be installed to
convert negative signal to positive.

Immobilizer relay
When connected as shown below, FM3620 disables engine starter when output is OFF.
More details about relays can be found below.

Relays
An ordinary automotive relay is used to invert input signal or to immobilize engine starter.
Note, that they are available as 12 V or 24 V.
